To lues： 这两天感冒头晕，基本上没有到公社来。

[quote:826b5ac095="lues"]但我的/etc/ha.d/haresources 已经写了
test3 IPaddr::210.75.11.37 ipvsadm ldirectord::www
为什么ldirectord没有启动呢？[/quote]

如果不是使用24位的掩码， /etc/ha.d/resources.d/IPaddr 脚本需要的IP地址参数要指定子网位数甚至网卡、广播地址，像这样的：
  IP地址/子网位数/广播地址

否则你只写一个 210.75.11.37 它启动不起来。

，我试了一下不行， ldirectord还是没有启动
我的LVS服务器：210.75.11.38
我的Real Server: 210.75.11.34
                           210.75.11.36


LVS服务器配置（采用LVS/DR模式）

我的ldirectord.cf是按照系统默认的，没有修改过

[root@test7 ha.d]# service ldirectord status
ldirectord is stopped for /etc/ha.d/ldirectord.cf

[root@test7 ha.d]# ifconfig

  -> 210.75.11.36:80              Route   1      0          2     


然后我down掉210.75.11.34的http服务，LVS服务器并没有自动删除其路由

你的 ha.cf 是前面那个吗？怎么没有指定 bcast 接口？
日志里有相关记录吗？

[quote:c8606f6cf2="dannycat"]你的 ha.cf 是前面那个吗？怎么没有指定 bcast 接口？

我的ha.cf确实没有指定bcast 接口，因为我发现udp 694就可以作为心跳线

我的ldirectord.log 如下

[root@test7 ha.d]# tail /var/log/ldirectord.log
[Mon Nov  1 12:54:20 2004|www] Config file www not found

[Mon Nov  1 12:54:25 2004|www] Exiting with exit_status 1: Initialisation Error

我的现在的ha.cf如下

debugfile /var/log/ha-debug
logfile /var/log/ha-log   
node test7               
node test9               
keepalive 2               
deadtime 20               
initdead 240              
udp eth1                  
udpport 694

我觉得奇怪，为什么会说Config file www not found

[root@test7 root]# cd /etc/ha.d
[root@test7 ha.d]# ls
authkeys  conf  ha.cf  harc  haresources  ldirectord.cf  rc.d  README.config  resource.d  shellfuncs  www.cf


此外，版主你的感冒好了吗？这么快就上来了

从日志看ldirectord www 已经启动了，只是www.cf配置文件系统没有找到

是 bcast eth1 吧？ 好象可以不要，不过还是加上的好，省得数据包乱发   没有仔细研究过，乱说的~~

呵呵，把 www.cf 改名成 www。

我现在在机房忙里偷闲将www.cf改为了www，启动以后没有Config file www not found 错误提示了，但是出现了 Exiting with exit_status 1: Initialisation Error，是不是我www的语法还是有错？
现在我的34服务器down掉了，但是ldirectord还是没有自动删除34的路由，

子网位数 32 ？

这个应该是工作了。

你直接运行 /etc/ha.d/resource.d/ldirectord www start 看看有什么反应。

重启后我尝试了down掉34、36的httpd服务,再观察ipvsadm
[root@test7 root]# ipvsadm
IP Virtual Server version 1.0.8 (size=65536)
Prot LocalAddressort Scheduler Flags
  -> RemoteAddressort           Forward Weight ActiveConn InActConn
TCP  210.75.11.37:http wlc
  -> 210.75.11.34:http            Route   1      0          3         
  -> test9:http                   Route   1      0          0   

虽然ipvsadm一直没有变化，但我在外部访问和/var/log/ldirectord.log的信息来看，ldirectord已经生效了





非常激动，我再增加一个http服务试试
