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

1234567891011121314 [Unit]Description=/etc/rc.local CompatibilityConditionPathExists=/etc/rc.local [Service]Type=forkingExecStart=/etc/rc.local startTimeoutSec=0StandardOutput=ttyRemainAfterExit=yesSysVStartPriority=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

1234567891011121314 #!/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

12 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
