请问squid的用法，我的启动不了
各位老大，我在启动squid时，它报错 “could not determin full qualified hostname.please set visible hostname"请问应该检查那里出的毛病，怎样解决，多谢！ 你能将你的/etc/squid/squid.conf配置部分挂出来吗？ 好的，我 看看 # WELCOME TO SQUID 2
# ------------------
#
# This is the default Squid configuration file. You may wish
# to look at the Squid home page (http://www.squid-cache.org/)
# for the FAQ and other documentation.
#
# The default Squid config file shows what the defaults for
# various options happen to be.If you don't need to change the
# default, you shouldn't uncomment the line.Doing so may cause
# run-time problems.In some cases "none" refers to no default
# setting at all, while in other cases it refers to a valid
# option - the comments for that keyword indicate if this is the
# case.
#
# NETWORK OPTIONS
# -----------------------------------------------------------------------------
#TAG: http_port
# Usage: port
# hostname:port
# 1.2.3.4:port
#
# The socket addresses where Squid will listen for HTTP client
# requests.You may specify multiple socket addresses.
# There are three forms: port alone, hostname with port, and
# IP address with port.If you specify a hostname or IP
# address, then Squid binds the socket to that specific
# address.This replaces the old 'tcp_incoming_address'
# option.Most likely, you do not need to bind to a specific
# address, so you can use the port number alone.
#
# The default port number is 3128.
#
# If you are running Squid in accelerator mode, then you
# probably want to listen on port 80 also, or instead.
#
# The -a command line option will override the *first* port
# number listed here. That option will NOT override an IP
# address, however.
#
# You may specify multiple socket addresses on multiple lines.
#
# If you run Squid on a dual-homed machine with an internal
# and an external interface then we recommend you to specify the
# internal address:port in http_port. This way Squid will only be
# visible on the internal address.
#
#Default:
# http_port 3128
#TAG: https_port
# Usage:port cert=certificate.pem
#
# The socket address where Squid will listen for HTTPS client
# requests.
#
# This is really only useful for situations where you are running
# squid in accelerator mode and you want to do the SSL work at the
# accelerator level.
#
# You may specify multiple socket addresses on multiple lines,
# each with their own SSL certificate and/or options.
#
# Options:
#
# cert= Path to SSL certificate (PEM format)
#
# key= Path to SSL private key file (PEM format)
# if not specified, the certificate file is
# assumed to be a combined certificate and
# key file
#
# version= The version of SSL/TLS supported
# 1 automatic (default)
# 2 SSLv2 only
# 3 SSLv3 only
# 4 TLSv1 only
#
# cipher= Colon separated list of supported ciphers
#
# options= Varions SSL engine options. The most important
# being:
# NO_SSLv2Disallow the use of SSLv2
# NO_SSLv3Disallow the use of SSLv3
# NO_TLSv1Disallow the use of TLSv1
# See src/ssl_support.c or OpenSSL documentation
# for a more complete list.
#
#Default:
# none
#TAG: ssl_unclean_shutdown
# Some browsers (especially MSIE) bugs out on SSL shutdown
# messages.
#
#Default:
# ssl_unclean_shutdown off
#TAG: icp_port
# The port number where Squid sends and receives ICP queries to
# and from neighbor caches.Default is 3130.To disable use
# "0".May be overridden with -u on the command line.
#
#Default:
# icp_port 3130
#TAG: htcp_port
# Note: This option is only available if Squid is rebuilt with the
# --enable-htcp option
#
# The port number where Squid sends and receives HTCP queries to
# and from neighbor caches.Default is 4827.To disable use
# "0".
#
#Default:
# htcp_port 4827
#TAG: mcast_groups
# This tag specifies a list of multicast groups which your server
# should join to receive multicasted ICP queries.
#
# NOTE!Be very careful what you put here!Be sure you
# understand the difference between an ICP _query_ and an ICP
# _reply_.This option is to be set only if you want to RECEIVE
# multicast queries.Do NOT set this option to SEND multicast
# ICP (use cache_peer for that).ICP replies are always sent via
# unicast, so this option does not affect whether or not you will
# receive replies from multicast group members.
#
# You must be very careful to NOT use a multicast address which
# is already in use by another group of caches.
#
# If you are unsure about multicast, please read the Multicast
# chapter in the Squid FAQ (http://www.squid-cache.org/FAQ/).
#
# Usage: mcast_groups 239.128.16.128 224.0.1.20
#
# By default, Squid doesn't listen on any multicast groups.
#
#Default:
# none
#TAG: udp_incoming_address
#TAG: udp_outgoing_address
# udp_incoming_address is used for the ICP socket receiving packets
# from other caches.
# udp_outgoing_address is used for ICP packets sent out to other
# caches.
#
# The default behavior is to not bind to any specific address.
#
# A udp_incoming_address value of 0.0.0.0 indicates that Squid should
# listen for UDP messages on all available interfaces.
#
# If udp_outgoing_address is set to 255.255.255.255 (the default)
# then it will use the same socket as udp_incoming_address. Only
# change this if you want to have ICP queries sent using another
# address than where this Squid listens for ICP queries from other
# caches.
#
# NOTE, udp_incoming_address and udp_outgoing_address can not
# have the same value since they both use port 3130.
#
#Default:
# udp_incoming_address 0.0.0.0
# udp_outgoing_address 255.255.255.255
# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
# -----------------------------------------------------------------------------
#TAG: cache_peer
# To specify other caches in a hierarchy, use the format:
#
# cache_peer hostname type http_port icp_port
#
# For example,
#
# # proxyicp
# # hostname type port portoptions
# # -------------------- -------- ----- ----------------
# cache_peer parent.foo.net parent 31283130
# cache_peer sib1.foo.net sibling 31283130
# cache_peer sib2.foo.net sibling 31283130
#
# type:either 'parent', 'sibling', or 'multicast'.
#
# proxy_port:The port number where the cache listens for proxy
# requests.
#
# icp_port:Used for querying neighbor caches about
# objects.To have a non-ICP neighbor
# specify '7' for the ICP port and make sure the
# neighbor machine has the UDP echo port
# enabled in its /etc/inetd.conf file.
#
# options: proxy-only
# weight=n
# ttl=n
# no-query
# default
# round-robin
# multicast-responder
# closest-only
# no-digest
# no-netdb-exchange
# no-delay
# login=user:password | PASS | *:password
# connect-timeout=nn
# digest-url=url
# allow-miss
# max-conn
#
# use 'proxy-only' to specify that objects fetched
# from this cache should not be saved locally.
#
# use 'weight=n' to specify a weighted parent.
# The weight must be an integer.The default weight
# is 1, larger weights are favored more.
#
# use 'ttl=n' to specify a IP multicast TTL to use
# when sending an ICP queries to this address.
# Only useful when sending to a multicast group.
# Because we don't accept ICP replies from random
# hosts, you must configure other group members as
# peers with the 'multicast-responder' option below.
#
# use 'no-query' to NOT send ICP queries to this
# neighbor.
#
# use 'default' if this is a parent cache which can
# be used as a "last-resort." You should probably
# only use 'default' in situations where you cannot
# use ICP with your parent cache(s).
#
# use 'round-robin' to define a set of parents which
# should be used in a round-robin fashion in the
# absence of any ICP queries.
#
# 'multicast-responder' indicates that the named peer
# is a member of a multicast group.ICP queries will
# not be sent directly to the peer, but ICP replies
# will be accepted from it.
#
# 'closest-only' indicates that, for ICP_OP_MISS
# replies, we'll only forward CLOSEST_PARENT_MISSes
# and never FIRST_PARENT_MISSes.
#
# use 'no-digest' to NOT request cache digests from
# this neighbor.
#
# 'no-netdb-exchange' disables requesting ICMP
# RTT database (NetDB) from the neighbor.
#
# use 'no-delay' to prevent access to this neighbor
# from influencing the delay pools.
#
# use 'login=user:password' if this is a personal/workgroup
# proxy and your parent requires proxy authentication.
# Note: The string can include URL escapes (i.e. %20 for
# spaces). This also means that % must be written as %%.
#
# use 'login=PASS' if users must authenticate against
# the upstream proxy. This will pass the users credentials
# as they are to the peer proxy. This only works for the
# Basic HTTP authentication sheme. Note: To combine this
# with proxy_auth both proxies must share the same user
# database as HTTP only allows for one proxy login.
# Also be warned that this will expose your users proxy
# password to the peer. USE WITH CAUTION
#
# use 'login=*:password' to pass the uname to the
# upstream cache, but with a fixed password. This is meant
# to be used when the peer is in another administrative
# domain, but it is still needed to identify each user.
# The star can optionally be followed by some extra
# information which is added to the uname. This can
# be used to identify this proxy to the peer, similar to
# the login=username:password option above.
#
# use 'connect-timeout=nn' to specify a peer
# specific connect timeout (also see the
# peer_connect_timeout directive)
#
# use 'digest-url=url' to tell Squid to fetch the cache
# digest (if digests are enabled) for this host from
# the specified URL rather than the Squid default
# location.
#
# use 'allow-miss' to disable Squid's use of only-if-cached
# when forwarding requests to siblings. This is primarily
# useful when icp_hit_stale is used by the sibling. To
# extensive use of this option may result in forwarding
# loops, and you should avoid having two-way peerings
# with this option. (for example to deny peer usage on
# requests from peer by denying cache_peer_access if the
# source is a peer)
#
# use 'max-conn' to limit the amount of connections Squid
# may open to this peer.
#
# NOTE: non-ICP neighbors must be specified as 'parent'.
#
#Default:
# none
#TAG: cache_peer_domain
# Use to limit the domains for which a neighbor cache will be
# queried.Usage:
#
# cache_peer_domain cache-host domain
# cache_peer_domain cache-host !domain
#
# For example, specifying
#
# cache_peer_domain parent.foo.net .edu
#
# has the effect such that UDP query packets are sent to
# 'bigserver' only when the requested object exists on a
# server in the .edu domain.Prefixing the domainname
# with '!' means that the cache will be queried for objects
# NOT in that domain.
#
# NOTE: * Any number of domains may be given for a cache-host,
# either on the same or separate lines.
# * When multiple domains are given for a particular
# cache-host, the first matched domain is applied.
# * Cache hosts with no domain restrictions are queried
# for all requests.
# * There are no defaults.
# * There is also a 'cache_peer_access' tag in the ACL
# section.

#
# Modifying the neighbor type for specific domains is now
# possible.You can treat some domains differently than the the
# default neighbor type specified on the 'cache_peer' line.
# Normally it should only be necessary to list domains which
# should be treated differently because the default neighbor type
# applies for hostnames which do not match domains listed here.
#
#EXAMPLE:
# cache_peerparent cache.foo.org 3128 3130

#
#Default:

#TAG: icp_query_timeout (msec)
# Normally Squid will automatically determine an optimal ICP
# query timeout value based on the round-trip-time of recent ICP
# queries.If you want to override the value determined by
# Squid, set this 'icp_query_timeout' to a non-zero value.This
# value is specified in MILLISECONDS, so, to use a 2-second
# timeout (the old default), you would write:
#
# icp_query_timeout 2000
#
#Default:
# icp_query_timeout 0
#TAG: maximum_icp_query_timeout (msec)
# Normally the ICP query timeout is determined dynamically.But
# sometimes it can lead to very large values (say 5 seconds).
# Use this option to put an upper limit on the dynamic timeout
# value.Do NOT use this option to always use a fixed (instead
# of a dynamic) timeout value. To set a fixed timeout see the
# 'icp_query_timeout' directive.
#
#Default:
# maximum_icp_query_timeout 2000
#TAG: mcast_icp_query_timeout (msec)
# For Multicast peers, Squid regularly sends out ICP "probes" to
# count how many other peers are listening on the given multicast
# address.This value specifies how long Squid should wait to
# count all the replies.The default is 2000 msec, or 2
# seconds.
#
#Default:
# mcast_icp_query_timeout 2000
#TAG: dead_peer_timeout (seconds)
# This controls how long Squid waits to declare a peer cache
# as "dead."If there are no ICP replies received in this
# amount of time, Squid will declare the peer dead and not
# expect to receive any further ICP replies.However, it
# continues to send ICP queries, and will mark the peer as
# alive upon receipt of the first subsequent ICP reply.
#
# This timeout also affects when Squid expects to receive ICP
# replies from peers.If more than 'dead_peer' seconds have
# passed since the last ICP reply was received, Squid will not
# expect to receive an ICP reply on the next query.Thus, if
# your time between requests is greater than this timeout, you
# will see a lot of requests sent DIRECT to origin servers
# instead of to your parents.
#
#Default:
# dead_peer_timeout 10 seconds
#TAG: hierarchy_stoplist
# A list of words which, if found in a URL, cause the object to

# and hot objects will be released.In other words, the
# negative-cached and hot objects will fill up any unused space
# not needed for in-transit objects.
#
# If circumstances require, this limit will be exceeded.
# Specifically, if your incoming request rate requires more than
# 'cache_mem' of memory to hold in-transit objects, Squid will
# exceed this limit to satisfy the new requests.When the load
# decreases, blocks will be freed until the high-water mark is
# reached.Thereafter, blocks will be used to store hot

#
# The heap GDSF policy optimizes object hit rate by keeping smaller

# it evicts larger (possibly popular) objects.
#
# The heap LFUDA policy keeps popular objects in cache regardless of
# their size and thus optimizes byte hit rate at the expense of
# hit rate since one large, popular object will prevent many
# smaller, slightly less popular objects from being cached.
#
# Both policies utilize a dynamic aging mechanism that prevents

#
# auth_param basic program /usr/bin/ncsa_auth /usr/etc/passwd
# would tell the basic authentication scheme it's program parameter.
#
# The order that authentication prompts are presented to the client_agent
# is dependant on the order the scheme first appears in config file.
# IE has a bug (it's not rfc 2617 compliant) in that it will use the basic
# scheme if basic is the first entry presented, even if more secure schemes
# are presented. For now use the order in the file below. If other browsers
# have difficulties (don't recognise the schemes offered even if you are using
# basic) then either put basic first, or disable the other schemes (by commenting
# out their program entry).
#
# Once an authentication scheme is fully configured, it can only be shutdown
# by shutting squid down and restarting. Changes can be made on the fly and
# activated with a reconfigure. I.E. You can change to a different helper,
# but not unconfigure the helper completely.
#
# === Parameters for the basic scheme follow. ===
#
# "program" cmdline
# Specify the command for the external authenticator.Such a
# program reads a line containing "username password" and replies
# "OK" or "ERR" in an endless loop.If you use an authenticator,
# make sure you have 1 acl of type proxy_auth.By default, the
# authenticate_program is not used.
#
# If you want to use the traditional proxy authentication,
# jump over to the ../auth_modules/NCSA directory and
# type:
# % make
# % make install
#
# Then, set this line to something like
#
# auth_param basic program /usr/bin/ncsa_auth /usr/etc/passwd
#
# "children" numberofchildren
# The number of authenticator processes to spawn (no default).
# If you start too few Squid will have to wait for them to
# process a backlog of usercode/password verifications, slowing
# it down. When password verifications are done via a (slow)
# network you are likely to need lots of authenticator
# processes.
# auth_param basic children 5
#
# "realm" realmstring
# Specifies the realm name which is to be reported to the
# client for the basic proxy authentication scheme (part of
# the text the user will see when prompted their uname and
# password). There is no default.
# auth_param basic realm Squid proxy-caching web server
#
# "credentialsttl" timetolive
# Specifies how long squid assumes an externally validated
# username:password pair is valid for - in other words how
# often the helper program is called for that user. Set this
# low to force revalidation with short lived passwords.Note
# that setting this high does not impact your susceptability
# to replay attacks unless you are using an one-time password
# system (such as SecureID).If you are using such a system,
# you will be vulnerable to replay attacks unless you also
# use the max_user_ip ACL in an http_access rule.
#
# === Parameters for the digest scheme follow ===
#
# "program" cmdline
# Specify the command for the external authenticator.Such
# a program reads a line containing "username":"realm" and
# replies with the appropriate H(A1) value base64 encoded.
# See rfc 2616 for the definition of H(A1).If you use an
# authenticator, make sure you have 1 acl of type proxy_auth.
# By default, authentication is not used.
#
# If you want to use build an authenticator,
# jump over to the ../digest_auth_modules directory and choose the
# authenticator to use. It it's directory type
# % make
# % make install
#
# Then, set this line to something like
#
# auth_param digest program /usr/bin/digest_auth_pw /usr/etc/digpass
#
#
# "children" numberofchildren
# The number of authenticator processes to spawn (no default).
# If you start too few Squid will have to wait for them to
# process a backlog of H(A1) calculations, slowing it down.
# When the H(A1) calculations are done via a (slow) network
# you are likely to need lots of authenticator processes.
# auth_param digest children 5
#
# "realm" realmstring
# Specifies the realm name which is to be reported to the
# client for the digest proxy authentication scheme (part of
# the text the user will see when prompted their uname and
# password). There is no default.
# auth_param digest realm Squid proxy-caching web server
#
# "nonce_garbage_interval" timeinterval
# Specifies the interval that nonces that have been issued
# to client_agent's are checked for validity.
#
# "nonce_max_duration" timeinterval
# Specifies the maximum length of time a given nonce will be
# valid for.
#
# "nonce_max_count" number
# Specifies the maximum number of times a given nonce can be
# used.
#
# "nonce_strictness" on|off
# Determines if squid requires increment-by-1 behaviour for
# nonce counts (on - the default), or strictly incrementing
# (off - for use when useragents generate nonce counts that
# occasionally miss 1 (ie, 1,2,4,6)).
#
# === NTLM scheme options follow ===
#
# "program" cmdline
# Specify the command for the external ntlm authenticator.
# Such a program reads a line containing the uuencoded NEGOTIATE
# and replies with the ntlm CHALLENGE, then waits for the
# response and answers with "OK" or "ERR" in an endless loop.
# If you use an ntlm authenticator, make sure you have 1 acl
# of type proxy_auth.By default, the ntlm authenticator_program
# is not used.
#
# auth_param ntlm program /usr/bin/ntlm_auth
#
# "children" numberofchildren
# The number of authenticator processes to spawn (no default).
# If you start too few Squid will have to wait for them to
# process a backlog of credential verifications, slowing it
# down. When crendential verifications are done via a (slow)
# network you are likely to need lots of authenticator
# processes.
# auth_param ntlm children 5
#
# "max_challenge_reuses" number
# The maximum number of times a challenge given by a ntlm
# authentication helper can be reused. Increasing this number
# increases your exposure to replay attacks on your network.
# 0 means use the challenge only once.(disable challenge
# caching) See max_ntlm_challenge_lifetime for more information.
# auth_param ntlm max_challenge_reuses 0
#
# "max_challenge_lifetime" timespan

# #
# # NOTE: proxy_auth requires a EXTERNAL authentication program

# #
# # WARNING: proxy_auth can't be used in a transparent proxy. It

#
# acl aclname snmp_community string ...
# # A community string to limit access to your SNMP Agent
# # Example:
# #
# # acl snmppublic snmp_community public
#
# acl aclname maxconn number
# # This will be matched when the client's IP address has
# # more than <number> HTTP connections established.
#
# acl aclname max_user_ip [-s] number
# # This will be matched when the user attempts to log in from more
# # than <number> different ip addresses. The authenticate_ip_ttl
# # parameter controls the timeout on the ip entries.
# # If -s is specified then the limit is strict, denying browsing
# # from any further IP addresses until the ttl has expired. Without
# # -s Squid will just annoy the user by "randomly" denying requests.
# # (the counter is then reset each time the limit is reached and a
# # request is denied)
# # NOTE: in acceleration mode or where there is mesh of child proxies,
# # clients may appear to come from multiple addresses if they are
# # going through proxy farms, so a limit of 1 may cause user problems.
#
# acl aclname req_mime_type mime-type1 ...
# # regex match agains the mime type of the request generated

# # to match the returned file type.
#
# acl aclname rep_mime_type mime-type1 ...
# # regex match against the mime type of the reply recieved by
# # squid. Can be used to detect file download or some
# # types HTTP tunelling requests.
# # NOTE: This has no effect in http_access rules. It only has
# # effect in rules that affect the reply data stream such as

#TAG: http_access
# Allowing or Denying access based on defined access lists
#
# Access to the HTTP port:
# http_access allow|deny [!]aclname ...
#
# NOTE on default values:
#
# If there are no "access" lines present, the default is to deny
# the request.
#
# If none of the "access" lines cause a match, the default is the
# opposite of the last line in the list.If the last line was
# deny, then the default is allow.Conversely, if the last line
# is allow, the default will be deny.For these reasons, it is a
# good idea to have an "deny all" or "allow all" entry at the end
# of your access lists to avoid potential confusion.
#
#Default:
# http_access deny all
#
#Recommended minimum configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
http_access deny manager
# Deny requests to unknown ports
http_access deny !Safe_ports
# Deny CONNECT to other than SSL ports
http_access deny CONNECT !SSL_ports
#
# We strongly recommend to uncomment the following to protect innocent
# web applications running on the proxy server who think that the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
# Exampe rule allowing access from your local networks. Adapt
# to list your (internal) IP networks from where browsing should
# be allowed
#acl our_networks src 192.168.1.0/24 192.168.2.0/24
#http_access allow our_networks
# And finally deny all other access to this proxy
http_access allow localhost
http_access deny all
#TAG: http_reply_access
# Allow replies to client requests. This is complementary to http_access.
#
# http_reply_access allow|deny [!] aclname ...
#
# NOTE: if there are no access lines present, the default is to allow
# all replies
#
# If none of the access lines cause a match, then the opposite of the
# last line will apply. Thus it is good practice to end the rules
# with an "allow all" or "deny all" entry.
#
#Default:
# http_reply_access allow all
#
#Recommended minimum configuration:
#
# Insert your own rules here.

#TAG: icp_access
# Allowing or Denying access to the ICP port based on defined

#
# See http_access for details
#
#Default:
# icp_access deny all
#
#Allow ICP queries from everyone

#TAG: miss_access
# Use to force your neighbors to use you as a sibling instead of
# a parent.For example:
#
# acl localclients src 172.16.0.0/16
# miss_access allow localclients
# miss_access deny!localclients
#
# This means that only your local clients are allowed to fetch
# MISSES and all other clients can only fetch HITS.
#
# By default, allow all clients who passed the http_access rules
# to fetch MISSES from us.
#
#Default setting:
# miss_access allow all
#TAG: cache_peer_access
# Similar to 'cache_peer_domain' but provides more flexibility by
# using ACL elements.
#
# cache_peer_access cache-host allow|deny [!]aclname ...
#
# The syntax is identical to 'http_access' and the other lists of
# ACL elements.See the comments for 'http_access' below, or
# the Squid FAQ (http://www.squid-cache.org/FAQ/FAQ-10.html).
#
#Default:
# none
#TAG: ident_lookup_access
# A list of ACL elements which, if matched, cause an ident
# (RFC 931) lookup to be performed for this request.For
# example, you might choose to always perform ident lookups
# for your main multi-user Unix boxes, but not for your Macs
# and PCs.By default, ident lookups are not performed for
# any requests.
#
# To enable ident lookups for specific client addresses, you
# can follow this example:
#
# acl ident_aware_hosts src 呵呵，我明白了，你压根就没有配置嘛。 让你 set visible_hostname 就 set 上好了：
在你的/etc/hosts里加上
你的IP你的机器名称
或者在squid.conf里加上
visible_hostname 你的机器名称 你需要看一些squid的文档：
http://squid.visolve.com/squid/squid24s1/squid24s1.pdf :oops:不好意思,发出去后,才发现里面居然都注释了,我居然以为有默认配置,当时看小说上瘾了,根本没检查,丢大人了,谢谢各位老大啊 U'r Welcome!
