CentOS系统,设置应用开机启动

1. 编写开机自启脚本,nginx为例

mkdir -p /opt/script/
vim /opt/script/sys-autostart-app.sh
# centos system autostart application shell
# nginx
/usr/local/nginx/sbin/nginx 

2. 配置自动启动脚本,1:

2.1. 设置开机启动脚本(自定义)可执行权限:

chmod +x /opt/script/sys-autostart-app.sh
cat /opt/script/sys-autostart-app.sh

# centos system autostart application shell
# nginx
/usr/local/nginx/sbin/nginx

2.2. 打开/etc/rc.d/rc.local文件,在末尾增加:

vim /etc/rc.d/rc.local
/opt/script/sys-autostart-app.sh

2.3. 在centos7中,/etc/rc.d/rc.local的权限被降低了,需要执行命令赋予其可执行权限:

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

3. 配置自动启动脚本,2:

3.1. 将脚本移动到/etc/rc.d/init.d目录下

mv /opt/script/sys-autostart-app.sh /etc/rc.d/init.d

3.2. 增加脚本的可执行权限

chmod +x /etc/rc.d/init.d/sys-autostart-app.sh

3.3. 添加脚本到开机自动启动项目中

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