restart the apache server
```
  service httpd restart
```
check the result on the browser

If Error, Debug steps:

  1. check whether the browser go to the apache server. If successful, you can find:

      Apache .....

  Or

      Internal Error 501/500 and so on.

  Then you can run the following command to debug:

      tail -n 20 /var/log/httpd/error_log

  You can get some info in the last lines of the output.

  2. if failed or you cannot got the apache server, you should check the url, the linux Network config, iptables, selinux and so on.

Tips

file permission can cause many bugs.
you should firstly confirm apache server is ok. After you installed&started the apache server, you can get the index.html on browser.
