如何启动/停止/重启MySQL
一、 启动方式

1、使用 service 启动:service mysql start

2、使用 mysqld 脚本启动:/etc/inint.d/mysql start

3、使用 safe_mysqld 启动:safe_mysql&

二、停止

1、使用 service 启动:service mysql stop

2、使用 mysqld 脚本启动:/etc/inint.d/mysql stop

3、mysqladmin shutdown

三、重启

1、使用 service 启动:service mysql restart

2、使用 mysqld 脚本启动:/etc/inint.d/mysql restart

刚开始学mysql时都是用redhat自带的。启动是什么 /rc.d/init.d/ start
这很简单,但是后来越学越多,系统自带的mysql,有的是版本太低,有的是与
自己想要装的web服务需要的低版本的mysql

后来自己学着以tar的方式安装mysql,我的mysql装在/usr/local/mysql目录下启

动碰到过很多问题。最常见的是:
ERROR 2002: Can’t connect to local MySQL server through socket

‘/tmp/mysql.sock’ (111)

解决办法:
[root@test mysql]# /usr/local/mysql/bin/mysqladmin -u root /

-S /var/lib/mysql/mysql.sock password ‘your.passwd’
或者做个连接
ln -s /var/lib/mysql/mysql.sock /tmp
其实提示找不到 /tmp/mysql.sock有时也并不是/tmp目录下没这个文件,是启动
命令不对,我碰到过
常见的几种启动方式,自己也不是记得很 清楚,如果你确定tmp下有mysql.sock这
个文件不妨试试另外的几个命令
/usr/local/mysql/bin/mysql -u root -p
/usr/local/mysql/bin/mysqld –user=mysql&
/usr/local/mysql/bin/mysqld –user=root&
/usr/local/mysql/bin/mysqld_safe –user=root&
/usr/local/mysql/bin/mysqld_safe –user=mysql&
/usr/local/mysql/bin/safe_mysqld–uer=root&(注意safe_mysqld与mysqld_safe是不同的,&表示mysql在后台运行)我的就会报错了
STOPPING server from pid file
/usr/local/mysql/data/localhost.localdomain.pid
060304 11:46:21 mysqld ended
这是权限问题,我的mysql目录属于root用户,也属于root群组,改用mysqld_safe启动就没问题了,
大家只要注意这几个mysql,safe_mysqld,mysqld_safe,mysqld,mysqladmin.多试
几次
其实有时mysql已经正 常启动了,查看mysql是否启动命令
ps -aux | grep mysqld
会看到如下类似内容
mysql 6394 0.0 1.5 10528 992 pts/3 S 16:16 0:00
/usr/local/mysql/
mysql 6395 0.0 1.5 10528 992 pts/3 S 16:16 0:00
/usr/local/mysql/
mysql 6396 0.0 1.5 10528 992 pts/3 S 16:16 0:00
/usr/local/mysql/
root 6422 0.0 1.1 2408 732 pts/3 S 16:20 0:00 grep
mysql

查看mysql是否在监 听端口命令
netstat -tl | grep mysql
会看到如下类似内容
tcp 0 0 :mysql :* LISTEN
