[[email protected] support-files]#

查看是否开启开机启动
[[email protected] support-files]# systemctl is-enabled mysqld3346     —-一种方式
mysqld3346.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mysqld3346 –level=5
enabled

[[email protected] support-files]# chkconfig –list mysqld3346 —两种方式
mysqld3346         0:off    1:off    2:on    3:on    4:on    5:on    6:off

—————mariadb多实例开机启动—————
现在增加 多实例开机启动脚本

vim /etc/rc.d/init.d/mumysql

#!/bin/bash
#add for chkconfig
#chkconfig: 2345 70 30
#description: mysql autostart
#processname: mumysql                  
/usr/bin/mysqld_multi –defaults-extra-file=/etc/mysql/cfg3325.cnf –log=/var/log/mysql/mysql_3325.log start

#end

说明:
2345是指脚本的运行级别,即在2345这4种模式下都可以运行,234都是文本界面,5就是图形界面X
70是指脚本将来的启动顺序号,如果别的程序的启动顺序号比70小(比如44、45),则脚本需要等这些程序都启动以后才启动。
30是指系统关闭时,脚本的停止顺序号。

chmod +x /etc/rc.d/init.d/mumysql
systemctl enable mumysql

[[email protected] support-files]# systemctl is-enabled mumysql
mumysql.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mumysql –level=5
enabled

[[email protected] init.d]# chkconfig –add mumysql   在系统里增加开记机启动
[[email protected] init.d]# chkconfig –list           查看开机启动列表。
mumysql            0:off    1:off    2:on    3:on    4:on    5:on    6:off
netconsole         0:off    1:off    2:off    3:off    4:off    5:off    6:off
network            0:off    1:off    2:on    3:on    4:on    5:on    6:off
