1、检查mysql的进程,如为X

2、kill X,与kill -9 X的区别

1)kill x :mysql的服务会停掉

2)kill -9 x:mysql的服务停掉,守护进程会将mysql服务拉起来

3)手动启动mysql服务

service mysqld start

4)手动停止mysql服务

service mysqld stop

5)命令行启动,命令行启动不支持restart
[root@VM-16-14-centos ~]# mysqld --no-defaults --user=mysql

汇总:

RedHat Linux上启停mysql

service mysqld start

service mysqld status

service mysqld stop

systemctl start mysqld

systemctl status mysqld

systemctl stop mysqld

mysqladmin shutdown

mysql -e 'shutdown'

mysql -e 'restart'

mysqld --user=mysql &  #命令行启动不支持restart
