help mysql的启动问题

help mysql的启动问题

安装redhat7.1版本,everything安装。
启动mysql
1.输入mysql ,显示error2002。
2.输入/usr/share/mysql/mysql.server start
显示starting mysqld daemon with databases from /var/lib/mysql
020110 mysqld ended
3.输入safe_mysqld -u root 显示和如上相同。
请问该如何进行操作。谢谢!10[/SIZE]       
/etc/rc.d/init.d/mysqld start
OR
root-->setup-->service-->mysql-->start
reboot      
另外请教一下
safe_mysqld  -u root
/usr/share/mysql/mysql.server start
启动的方法和/etc/rc.d/init.d/mysql start 有何不同
谢谢!      
我的错误跟你一样:  error 2002:  can`t connect to local mysql server through socket '/var/lib/mysql/mysql.sock'(2)

也照上面的方法做了,但是还不行。  
谢谢      
/etc/rc.d/init.d/mysqld is a chkconfig file!
It is a script that point to safe_mysqld and mysql.server!
It is writed by mysql!      
偶运行/etc/rc.d/init.d/mysqld start 即可,
如果你有错误,看一下/var/log/ 关于mysql的帖出来,      
你比我幸运多了。  /var/log/messages  关于mysql只有如下两行:
mysqld: starting mysql:succeeded
....
mysqld:stopping mysql:succeeded

*********
最近倒霉事比较多.....      
想这样的/var/log/mysqld.log有没有,帖出来.      
都是重复这几句:
020124 10:27:01  mysqld started
/usr/libexec/mysqld: ready for connections
020124 12:20:33  /usr/libexec/mysqld: Normal shutdown

020124 12:20:33  /usr/libexec/mysqld: Shutdown Complete      
/usr/bin/mysql_install_db
试一试即先初始化一下数据库
