急急急!有关mysql问题?

wzflinux

我安装了mysql3.23.56,
./configure -prefix=/usr/local/mysql
make
make install
然后初始化,一切正常,但是当我运行/usr/local/mysql/bin/safe_mysqld &   的时候,显示
chown:'mysql' :无效的用户
starting mysqld daemon with databases from/usr/local/mysql/var
[1]+done                           /usr/local/mysql/bin/safe_mysqld
最后显示mysqld dened
不知道是什么原因,请个位帮个忙,不胜感激!

还有,当联接时出现
ERROR2002:can't connet to local mysql server through socket "/tmp/mysql.sock
