linux - rc.local 自启动脚本的问题

Question

centos7 配置了shadowsocks，想简单地配置开机启动，于是在 /etc/rc.local中添加启动的命令如图：

直接运行 /etc/rc.local 是可以启动的，而且也给了rc.local执行权限 chmod +x /etc/rc.local

但是为什么reboot的时候不会运行呢，reboot完后我systemctl status rc-local,得到的是：

shadowsocks启动不了。但是当我systemctl restart rc-local的时候：

此时就正常启动了。那这还有什么开机启动的意义，请问是为何？

Answer 1

It turns out that it is not a problem with rc.local, but a problem with ss configuration. I logged the ss log and found it. .

Answer 2

Because of the soft link of /etc/rc.local是文件/etc/rc.d/rc.local, you need to give the latter executable permission, and then restart it to start it:

chmod 755 /etc/rc.d/rc.local
