———-mysql多實例開機啟動及加入服務———————–

將腳本cp到init.d目錄

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??? —-開機啟動

mysqld3346.service is not a native service, redirecting to /sbin/chkconfig.?? —–有報錯，開機啟動加入失敗

查看是否開啟開機啟動

[root@mysql02 support-files]# systemctl is-enabled mysqld3346???? —-一種方式

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 —兩種方式

mysqld3346???????? 0:off??? 1:off??? 2:on??? 3:on??? 4:on??? 5:on??? 6:off

—————mariadb多實例開機啟動—————

現在增加 多實例開機啟動腳本

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

說明：

2345是指腳本的運行級別，即在2345這4種模式下都可以運行，234都是文本界面，5就是圖形界面X

70是指腳本將來的啟動順序號，如果別的程序的啟動順序號比70小(比如44、45)，則腳本需要等這些程序都啟動以后才啟動。

30是指系統關閉時，腳本的停止順序號。

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?? 在系統里增加開記機啟動

[root@shjhmysql01 init.d]# chkconfig –list?????????? 查看開機啟動列表。

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
