Script Method for Linux Startup and Shutdown

1. Create a script under/etc/rc. d/init. d/to comply with the service script standard;

For example:

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. Modify the execution script permission

Chown-r root/etc/rc. d/init. d/GFS
Chmod 700/etc/rc. d/init. d/GFS

3. Create a symbolic connection for startup (S stands for START, K stands for START, K stands for kill, and stands for close. Number indicates the order of startup)

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. Create shutdown and execute

1) empty file in/var/lock/subsys

Touch/var/lock/subsys/GFS

2) create a shutdown symbolic connection

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
