系统自带服务/lib/systemd/system/rc-local.service
软连接为 /lib/systemd/system/rc.local.service -> rc-local.service

可以看到此文件缺少[install]部分，为他加上。
[Install]
WantedBy=multi-user.target
输入systemctl enable rc-local.service
系统启动时将执行/etc/rc.local文件里的内容
16.10开始不再有/etc/rc.local文件
创建
printf ‘%s\n‘ ‘#!/bin/bash‘ ‘exit 0‘ | sudo tee -a /etc/rc.local
vim /etc/rc.local
添加以下内容用于测试
#!/bin/bash touch /var/lock/subsys/local source /etc/profile echo `date`,"ok" >>/tmp/test-rc-local.log
sudo chmod +x /etc/rc.local
重启后看效果
