Linux配置开机自启动执行脚本有哪些方法

Question

如题所述

Answer 1

设置test.sh为开机要启动的脚本
[root@oldboy scripts]# vim /server/scripts/test.sh
[root@oldboy scripts]# cat /server/scripts/ test.sh
#!/bin/bash
/bin/echo $(/bin/date +%F_%T) >> /tmp/ test.log
方法一：修改/etc/rc.local
[root@oldboy ~]# ll /etc/rc.local
lrwxrwxrwx. 1 root root 13 Mar 30 10:50 /etc/rc.local -> rc.d/rc.local
修改/etc/rc.local文件
[root@oldboy scripts]# tail -n 1 /etc/rc.local
/bin/bash /server/scripts/test.sh >/dev/null 2>/dev/null
重启系统，查看结果
[root@oldboy ~]# cat /tmp/test.log
2018-03-30_12:00:10
方法二：chkconfig管理
删除掉方法一的配置
[root@oldboy ~]# vim /etc/init.d/test
#!/bin/bash
# chkconfig: 3 88 88
/bin/bash /server/scripts/test.sh >/dev/null 2>/dev/null
[root@oldboy ~]# chmod +x /etc/init.d/test
添加到chkconfig，开机自启动
[root@oldboy ~]# chkconfig --add test
[root@oldboy ~]# 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@oldboy ~]# cat /tmp/test.log
2018-03-30_12:00:10
2018-03-30_12:33:20
操作成功
关闭开机启动
[root@oldboy ~]# chkconfig test off
[root@oldboy ~]# 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@oldboy ~]# chkconfig --list test
test 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[root@oldboy ~]# chkconfig --del test
[root@oldboy ~]# chkconfig --list test
service test supports chkconfig, but is not referenced in any runlevel (run
'chkconfig --add test')

Answer 2

1.执行脚本的命令放到/etc/rc.local
2.脚本放到你想要的开机启动的级别的/ect/rc.d/rcX.d
中
X是开机等级
0
1
2
3
4
5
6
3.脚本放到/etc/init.d
不知道对不对
目前知道就这样么多了

设置test.sh为开机要启动的脚本

[root@oldboy scripts]# vim /server/scripts/test.sh

[root@oldboy scripts]# cat /server/scripts/ test.sh

#!/bin/bash

/bin/echo $(/bin/date +%F_%T) >> /tmp/ test.log

方法一：修改/etc/rc.local

[root@oldboy ~]# ll /etc/rc.local

lrwxrwxrwx. 1 root root 13 Mar 30 10:50 /etc/rc.local -> rc.d/rc.local

修改/etc/rc.local文件

[root@oldboy scripts]# tail -n 1 /etc/rc.local

/bin/bash /server/scripts/test.sh >/dev/null 2>/dev/null

重启系统，查看结果

[root@oldboy ~]# cat /tmp/test.log

2018-03-30_12:00:10

方法二：chkconfig管理

删除掉方法一的配置

[root@oldboy ~]# vim /etc/init.d/test

#!/bin/bash

# chkconfig: 3 88 88

/bin/bash /server/scripts/test.sh >/dev/null 2>/dev/null

[root@oldboy ~]# chmod +x /etc/init.d/test

添加到chkconfig，开机自启动

[root@oldboy ~]# chkconfig --add test

[root@oldboy ~]# 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@oldboy ~]# cat /tmp/test.log

2018-03-30_12:00:10

2018-03-30_12:33:20

操作成功

关闭开机启动

[root@oldboy ~]# chkconfig test off

[root@oldboy ~]# 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@oldboy ~]# chkconfig --list test

test 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[root@oldboy ~]# chkconfig --del test

[root@oldboy ~]# chkconfig --list test

service test supports chkconfig, but is not referenced in any runlevel (run
'chkconfig --add test')
