概要：
thinkphp 在Apache上配置启用伪静态，重启Apache1 restart 竟然失败了，报错
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details
嗯，看状态
执行命令 systemctl status httpd.service
[root@cloud1 bin]# systemctl status httpd.service

从上可以看到，80端口被占用了
执行journalctl -xe

上面这是查看日志
查看Apache中的 httpd-vhosts.conf 文件，发现Listen 80 两次，httpd-vhosts.conf一次，httpd.conf一次
虚拟机里的加个#Listen 80 OK解决了
备注：apache\Apache\conf下，extra和original文件夹的含义
extra的意思是额外扩展
original的意思是源目录文件
original文件夹是配置文件的源文件备份，而真正要配置的是conf目录下的httpd.conf文件以及extra目录的额外扩展配置。
