centos7以后rc.local和之前的有不太一样了，centos7默认开机不会执行，那是什么原因呢，其实细心点看rc.local的注释就知道了

#!/bin/bash#这个文件是为兼容性才添加的# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES#强烈建议使用systemd服务或udev规则来运行开机启动脚本,而不是使用这个文件# It is highly advisable to create own systemd services or udev rules to run scripts during boot instead of using this file.#与以前的版本引导时的并行执行相相比，这个脚本将不会在其它服务后执行# In contrast to previous versions due to parallel execution during boot this script will NOT be run after all other services.#请记住：你必须运行'chmod +x /etc/rc.d/rc.local'来确保这个脚本在启动时执行# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure that this script will be executed during boot.

看了上面的注释就明白了吧，其实给rc.local加上执行权限就可以了

[root@localhost ~]# ll /etc/rc.locallrwxrwxrwx. 1 root root 13 2月  16 23:32 /etc/rc.local -> rc.d/rc.local[root@localhost ~]# ll /etc/rc.d/rc.local-rw-r--r--. 1 root root 502 3月   9 00:16 /etc/rc.d/rc.local[root@localhost ~]# chmod +x /etc/rc.d/rc.local[root@localhost ~]# ll /etc/rc.d/rc.local-rwxr-xr-x. 1 root root 502 3月   9 00:16 /etc/rc.d/rc.local
