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

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[Unit] Description=/etc/rc.local Compatibility ConditionPathExists=/etc/rc.local   [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes SysVStartPriority=99   [Install] WantedBy=multi-user.target

3、创建文件rc.local　　

1	sudo vi /etc/rc.local

4、将下列内容复制进rc.local文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14

#!/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.log exit 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.service sudo 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
