linux重启MYSQL的命令

 

一、启动方式 

 

1、使用 service 启动:service mysqld start 

 

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

 

3、使用 safe_mysqld 启动:safe_mysqld& 

 

二、停止 

 

1、使用 service 启动:service mysqld stop 

 

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

 

3、 mysqladmin shutdown 

 

三、重启 

 

1、 使用 service 启动:service mysqld restart 

 

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