Linux自启动执行脚本方法

来源：互联网发布：java读取文件编辑：程序博客网时间：2024/04/30 09:45

1. 在/etc/rc.d/init.d/下创建脚本，要遵守service script的标准；

例如：

vi /etc/rc.d/init.d/gfs

#!/bin/bash
#

case "$1" in
restart)
    echo "umount /data"
    umount /data
    echo "mount /data"
    touch /var/lock/subsys/gfs
    mount -t gfs2 /dev/gfsvg/gfs /data
    ;;
start)
    echo "mount /data"
    touch /var/lock/subsys/gfs
    mount -t gfs2 /dev/gfsvg/gfs /data
    ;;
stop)
    echo "umount /data"
    umount /data
    ;;
*)
    echo "Usage: $0 {restart|start|stop}"
    exit 1
esac
exit 1

2. 修改执行脚本权限

chown -R root /etc/rc.d/init.d/gfs
chmod 700 /etc/rc.d/init.d/gfs

3. 创建开机启动的符号连接（S 是start的简写、代表启动、K是kill的简写、代表关闭。数字代表启动的顺序）

who -r 检查当前运行级别，然后再对应的rc*.d中增加软连

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc0.d/S60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc1.d/S60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc2.d/S60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc3.d/S60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc4.d/S60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc5.d/S60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc6.d/S60gfs

4. 创建关机执行

1）在/var/lock/subsys空文件

touch /var/lock/subsys/gfs

2）创建关机符号连接

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc0.d/K60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc1.d/K60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc2.d/K60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc3.d/K60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc4.d/K60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc5.d/K60gfs

ln -s /etc/rc.d/init.d/gfs /etc/rc.d/rc6.d/K60gfs
