原因解析

在centos7，使用ls -l /etc/rc.loacl可以看到如下结果
lrwxrwxrwx. 1 root root 13 7月  31 22:02 /etc/rc.local -> rc.d/rc.local

可以看到上面的执行结果是显示有执行权限的，
但是当使用ls -l /etc/rc.d/rc.loacl的时候却可以看到如下结果
-rw-r--r--. 1 root root 730 Sep 27 05:38 /etc/rc.d/rc.local
/etc/rc.loacl所链接的文件是没有执行权限的，
所以在启动的时候rc.local中写的命令得不到执行，
因此需要手动添加执行权限给/etc/rc.d/rc.loacl


解决办法

Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
打开 就有提示哦  请用心看 哈哈 

chmod +x /etc/rc.d/rc.local

关于在rc.local文件中指定用户执行脚本命令

使用su命令即可，命令格式：

su - username -c “your-cammand” ,如：

注意：指定用户执行的脚本（程序）目录，该用户必须有管理该脚本（程序）目录（文件）的权限。

最好将该脚本（程序）目录的所有权给该用户：




tail  boot.log
[  OK  ] Started Network Time Service.
[FAILED] Failed to start /etc/rc.d/rc.local Compatibility.
See 'systemctl status rc-local.service' for details.

#启动rc-local 服务  on aliyun 不要不小心 不清空了  /etc/rc.d/rc.local
 systemctl enable  rc-local.service
