linux mysql状态、启动、停止、重启命令

1.查看mysql状态

【1】ps -ef|grep mysqld 看看是否有mysqld_safe 和mysqld进程

  [root@localhost ~]# ps -ef|grep mysqld
  显示结果:

  1)root 4052 29869 0 10:25 pts/0 00:00:00 grep mysqld
  2)root 30905 1 0 10:14 pts/0 00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/localhost.localdomain.pid
  3)mysql 31231 30905 1 10:14 pts/0 00:00:09 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-                      error=/usr/local/mysql/data/localhost.localdomain.err --pid-file=/usr/local/mysql/data/localhost.localdomain.pid --socket=/tmp/mysqld.sock --port=3306                                    
【2】如果已添加到系统服务中,可以service mysqld status
  [root@localhost ~]# service mysqld status
  显示结果:
  SUCCESS! MySQL running (31231)

2.启动MySQL服务

/etc/init.d/mysqld start

也可以用/etc/init.d/mysqld的简化命令启动MySQL服务:service mysqld start

3.停止MySQL服务

/etc/init.d/mysqld stop

也可以使用服务命令:service mysqld stop

4.重启MySQL服务

/etc/init.d/mysqld restart

 也可以使用服务命令:service mysqld restart

 

输入mysql -u root -p出现错误:-bash: mysql: command not found
输入:alias mysql=/usr/local/mysql/bin/mysql
再重复mysql -u root -p,输入mysql口令即可
