ubuntu-18.04不能像ubuntu14一样通过编辑rc.local来设置开机启动脚本，通过下列简单设置后，可以使rc.local重新发挥作用。
1、建立rc-local.service文件
|
1
|
sudo vi /etc/systemd/system/rc-local.service |
2、将下列内容复制进rc-local.service文件

3、创建文件rc.local

sudo 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.echo "看到这行字，说明添加自启动脚本成功。" > /usr/local/test.logexit 0 |
5、给rc.local加上权限
|
1
|
sudo chmod +x /etc/rc.local |
6、启用服务
|
1
|
sudo systemctl enable rc-local |
7、启动服务并检查状态
|
1
2
|
sudo systemctl start rc-local.servicesudo systemctl status rc-local.service |
8、重启并检查test.log文件
|
1
|
cat /usr/local/test.log |
如果能看到内容，说明设置成功，你就可以通过编辑rc.local文件来设置启动脚本了
