———-mysql多实例开机启动及加入服务———————–

将脚本cp到init.d目录

cd /usr/mysqlsoft5.6.38_3346/support-files/

[root@mysql02 support-files]# cp mysql.server /etc/init.d/mysqld3346

[root@mysql02 support-files]# systemctl status mysqld3346

Unit mysqld3346.service could not be found.

[root@mysql02 support-files]# systemctl enable mysqld3346    —-开机启动

mysqld3346.service is not a native service, redirecting to /sbin/chkconfig.   —–有报错，开机启动加入失败

查看是否开启开机启动

[root@mysql02 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

[root@mysql02 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

[root@shtsmysql02 support-files]# systemctl is-enabled mumysql

mumysql.service is not a native service, redirecting to /sbin/chkconfig.

Executing /sbin/chkconfig mumysql –level=5

enabled

[root@shjhmysql01 init.d]# chkconfig –add mumysql   在系统里增加开记机启动

[root@shjhmysql01 init.d]# chkconfig –list           查看开机启动列表。
