Ubuntu下启动后网卡没有服务没有启动的问题

参照了很多帖子，两个典型的帖子分别是
https://blog.csdn.net/ErErFei/article/details/98205463
Ubuntu 18.04设置开机自动启动
https://blog.csdn.net/weixin_42116341/article/details/81410805
Ubuntu输入ifconfig找不到IP地址，只有lo问题

和第二个帖子里面不同的是，我的每次重启都要敲一遍这个命令

sudo dhclient ens33
sudo ifconfig ens33

所以就参照第一个帖子吧这两条命令在启动时候执行。
添加内容：

#以下为添加项
sudo dhclient eno1
sudo ifconfig eno1
#添加log输出，以确认命令正确执行
sudo echo “the enthernet boot information!” > /usr/local/text1.log
#以上为添加项

具体如下：

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

#以下为添加项
sudo dhclient eno1
sudo ifconfig eno1
# 添加log输出，以确认命令正确执行
sudo echo "the enthernet boot information!" > /usr/local/text1.log
#以上为添加项

sudo echo "just test" > /usr/local/text.log
exit 0

reboot后ifconfig，网卡显示出来了

结束，收工。
