Linux配置开机自启动执行脚本的两种方法

开机要启动的脚本qidong.sh

[root@c69-01 scripts]# vim /server/scripts/qidong.sh

[root@c69-01 scripts]# cat /server/scripts/qidong.sh
#!/bin/bash
/bin/echo $(/bin/date +%F_%T) >> /tmp/qidong.log

方法一:修改/etc/rc.local

/etc/rc.local,该文件为链接文件,/etc/rc.local 是 /etc/rc.d/rc.local 的软连接

[root@c69-01 ~]# ll /etc/rc.local 
lrwxrwxrwx. 1 root root 13 Feb  5 10:03 /etc/rc.local -> rc.d/rc.local

修改/etc/rc.local文件

[root@c69-01 scripts]# tail -n 1 /etc/rc.local 
/bin/bash /server/scripts/qidong.sh >/dev/null 2>/dev/null

为/etc/rc.d/rc.local 增加x权限

# ll /etc/rc.d/rc.local 
-rw-r-xr-x

# chmod 755 /etc/rc.d/rc.local

# ll /etc/rc.d/rc.local 
-rwxr-xr-x. 1 root root 490 Jul 30 15:54 /etc/rc.d/rc.local

重启系统,查看结果

[root@c69-01 ~]# cat /tmp/qidong.log 
2018-02-19_23:30:56

已开机自启动该脚本

方法二:chkconfig管理

删除掉方法一的配置

[root@c69-01 ~]# vim /etc/init.d/test 
#!/bin/bash
# chkconfig: 3 88 88
/bin/bash /server/scripts/qidong.sh >/dev/null 2>/dev/null

[root@c69-01 ~]# chmod +x /etc/init.d/test

添加到chkconfig,开机自启动

[root@c69-01 ~]# chkconfig --add test
[root@c69-01 ~]# chkconfig --list test
test           	0:off	1:off	2:off	3:on	4:off	5:off	6:off

重启系统,查看结果

[root@c69-01 ~]# cat /tmp/qidong.log 
2018-02-19_23:30:56
2018-02-19_23:59:10

操作成功

关闭开机启动

[root@c69-01 ~]# chkconfig test off
[root@c69-01 ~]# chkconfig --list test
test           	0:off	1:off	2:off	3:off	4:off	5:off	6:off

从chkconfig管理中删除test

[root@c69-01 ~]# chkconfig --list test
test           	0:off	1:off	2:off	3:off	4:off	5:off	6:off

[root@c69-01 ~]# chkconfig --del test

[root@c69-01 ~]# chkconfig --list test
service test supports chkconfig, but is not referenced in any runlevel (run 'chkconfig --add test')

 以上2种开机自启动脚本的方法,仅供参考,可根据自己的情况,进行配置!
