Centos7 add startup service/script

1. Add self-start service after boot

It is very convenient to add the self-start service in centos7, only two commands are needed (take Jenkins as an example):

systemctl enable mariadb.service #设置服务为自启动服务
sysstemctl start  mariadb.service #启动mariadb服务

Two, add boot scripts

There are two common ways to add scripts in centos7. Take the script autostart.sh as an example:

#!/bin/bash
# chkconfig: - 85 15
# description:开机自启脚本
/usr/local/tomcat/bin/startup.sh  #启动tomcat

method one

1. Grant script executable permissions (/opt/script/autostart.sh is your script path)

chmod +x /opt/script/autostart.sh 

2. Open the /etc/rc.d/rc.local file and add the following content at the end

/opt/script/autostart.sh

3. In centos7, the permissions of /etc/rc.d/rc.local have been reduced, so you need to execute the following commands to give it executable permissions

chmod +x /etc/rc.d/rc.local

The above methods have been verified on the centos7 system, and the centos version is 7.3

Method Two

1. Move the script to the /etc/rc.d/init.d directory

mv  /opt/script/autostart.sh /etc/rc.d/init.d

2. Increase the executable permissions of the script

chmod +x  /etc/rc.d/init.d/autostart.sh

3. Add scripts to the automatic startup project

cd /etc/rc.d/init.d
chkconfig --add autostart.sh
chkconfig autostart.sh on
