编辑 /etc/rc.local 文件

vim /etc/rc.local

在文件底部加入需要执行的命令,示例如下:

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
touch /var/lock/subsys/local
ip route delete default via 172.19.79.253 dev eth0 proto dhcp metric 100  #示例

保存,reboot 重启,查看命令是否正常执行。
如果命令没有正常执行,可能是未设置 /etc/rc.local 文件的执行权限:

chmod +x /etc/rc.local

再次重启,就可以正常自动执行了。
