linux安装mysql提示mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

输入命令后报错：
[root@dev1 mysql]# bin/mysqld_safe --user=mysql &
[1] 15325
[root@dev1 mysql]# 091217 22:22:53 mysqld_safe Logging to '/var/lib/mysql/dev1.sccl.cn.err'.
091217 22:22:53 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
091217 22:23:01 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

[root@dev1 mysql5.1]# bin/mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (1)

解决办法
vi /etc/my.cnf
把
[mysqld_safe]
err-log=/var/log/mysqld.log
pid-file=/var/lib/run/mysql/mysqld.pid
改成
[mysqld_safe]
err-log=/var/log/mysqld.log
pid-file=/var/lib/mysql/mysqld.pid

好现象，貌似启动成功了，插件进程
[root@dev1 log]# ps -aux | grep mysql
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.3/FAQ

root     15613 0.0 0.0 5976 656 pts/0    S+   22:44   0:00 grep mysql

但是登陆还是报错，修改如下：
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

登陆老是提醒我登陆的用户名和密码不对，我重新设置了一下密码
mysql -u root(默认密码为空)
登陆
登陆终于成功了：），好事多磨啊。
