as4的mysql启动问题

Question

#service mysqld start
Timeout error occurred trying to start MySQL Daemon. Faild
#
是系统自带的，配置文件如下/etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/tmp/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
     
[mysql.server]
user=mysql
basedir=/var/lib

[mysqld_safe]
err-log=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
感觉内容少了很多
请教！
