Linux 开机执行脚本方法

1. 方式一修改/etc/rc.local

tail -2 /etc/rc.local

touch /root/aa.txt

/bin/bash /root/shell/redis-start.sh >/dev/null 2>/dev/null

2. 方式二chkconfig管理

  2 > 第二种方式

[root​​@redis​​ ~]# cat /etc/init.d/redis-6379

#!/bin/bash

# chkconfig: 3 88 88

/bin/bash /server/scripts/redis-6379-start.sh >/dev/null 2>/dev/null

[root​​@redis​​ ~]# chmod +x /etc/init.d/redis-6379

#添加到chkconfig，开机自启动

[root​​@redis​​ ~]# chkconfig --add redis-6379

[root​​@redis​​ ~]# chkconfig --list redis-6379

redis-6379               0:off    1:off    2:off    3:on    4:off    5:off    6:off

重启系统，查看结果

[root​​@redis​​ ~]# cat /tmp/redis-6379-start.log

2020-12-19_09:59:10

操作成功

关闭开机启动

[root@redis ~]# chkconfig redis-6379 off

[root@redis ~]# chkconfig --list redis-6379

redis-6379               0:off    1:off    2:off    3:off    4:off    5:off    6:off

从chkconfig管理中删除redis-6379

[root@redis ~]# chkconfig --list redis-6379

redis_6379         0:关    1:关    2:开    3:开    4:开    5:开    6:关

[root@redis ~]# chkconfig --del redis-6379
