ubuntu ens33网卡掉线问题配置系统重启后自动加载网卡驱动

 

cd /lib/systemd/system

 

进入system目录 找到 rc-local.service 文件

cat rc-local.service

[Unit]
Description=/etc/rc.local Compatibility
Documentation=man:systemd-rc-local-generator(8)
ConditionFileIsExecutable=/etc/rc.local
After=network.target

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
RemainAfterExit=yes
GuessMainPID=no

可以看到ExecStart指向了/etc/rc.local,去到 etc目录找到rc.local，没有则创建(sudo touch rc.local)，添加以下内容：

#!/bin/bash
sudo dhclient ens33

保存后退出。

sudo systemctl enable rc-local
sudo systemctl start rc-local
sudo systemctl status rc-local
sudo systemctl restart rc-local
