ubuntu-18.04 设置开机启动脚本
原文地址：https://www.jianshu.com/p/79d24b4af4e5
在设置frp的时候，需要添加到开机自启动项目中。不过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
sudo vi /etc/systemd/system/rc-local .service
2.将下列内容复制进rc-local.service文件
[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
sudo vi /etc/rc.local
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.log exit 0
4.给rc.local加上权限,启用服务
sudo chmod +x /etc/rc.local
sudo systemctl enable rc-local
启动服务并检查状态
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
5.重启并检查test.log文件
cat /usr/local/test.log
