CentOS上启动Apache报错

系统版本为 CentOS 7，启动Apache报错

[root@localhost wiki]# service httpd start
Redirecting to /bin/systemctl start  httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

从网上查到的说法是端口被占用，解决办法是找到被占用的这个端口然后kill掉对应的进程，然后再重启httpd。但这个方法对我没有用，因为该服务器上之前就部署过禅道和SVN，而我查了该端口对应的应用程序就是Nginx，我没法kill它对应的进程，那在这个情况下，该怎么做呢？

1. 首先，我认为有必要评估下，是否有足够的理由同时部署Nginx和Apache。换句话说，Apache上有什么需求是Nginx不能顺带做了的？
2. 如果一定有理由的话，由于Nginx是主配，那么就需要改一下Apache的设置，比如原来监听的是80接口，那么现在就可以改到8080或者任意一个未被占用的接口上去，这样才能保证二者不会冲突。
3. 由于Nginx是在前级接收请求的，那么需要把原本需要给Apache的请求单独挑出来，反代到Apache监听的接口上去。网上Nginx反代的配置太多了，不再赘述。
