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、打开/etc/systemd/system/rc-local.service,在后面加上
[Install]WantedBy=multi-user.targetAlias=rc-local.service
如果/etc/systemd/system/下没有rc-local.service,可在/lib/systemd/system/下找到这个文件,然后做软链接。
2、创建文件rc.local
sudo vi /etc/rc.local
3、将下列内容复制进rc.local文件
#!/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
4、给rc.local加上权限
sudo chmod +x /etc/rc.local
5、启用服务
sudo systemctl enable rc-local
