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 Failed to start /etc/rc.d/rc.local Compatibility #原内容哦 有时改了就不行 要原文件 cat /etc/rc.d/rc.local #!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot.
