/etc/rc.local脚本是一个ubuntu开机后会自动执行的脚本,咱们能够在该脚本内添加命令行指令。该文件须要root权限才能修改。该脚本具体格式以下,shell
注意,必定要将命令添加在 exit 0以前,好比我用VirtualBox启动Ubuntu虚拟机,虚拟机上配置的 网络链接是桥接模式,但Ubuntu每次启动后,网络ubuntu
都链接不上,须要启动后,本身再执行NetworkManager命令,这里,咱们就能够将这个命令的执行放在/etc/rc.local里面,bash

# 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.
