因为ubuntu18已经没有用rc.local，因为日常用的习惯所以我们下面进行创建

1.创建rc.local软链接（因为system只会读取/etc/systemd/system下的文件）

ln -fs /lib/systemd/system/rc-local.service /etc/systemd/system/rc-local.service

2.修改/lib/systemd/system/rc-local.service文件

[Install]
WantedBy=multi-user.target #运行级别
Alias=rc-local.service

3.创建rc.local

 

 

touch /etc/rc.local
chmod 755 /etc/rc.local #添加权限

 

4. vi  /etc/rc.local

#!/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.
