Apache has configured a multi-domain site, but access to the third domain site shows the page is indeed the first domain site?

RT, my centos6.5 system server previously set two domain name sites, everything is normal, but today set a third domain name site (the method is exactly the same as the previous two) however, when you open the third domain name site, it is indeed the content of the first domain name site. the server has been restarted for N times...

So what is the problem?

Check whether the port configuration is correct.
There is also a better way to paste the configuration. I don't know which method you are using.

Check if the host is bound?

If the three's port and ip is same as the one;
You will get the ONE.
You can't get the three.
Please paste your configure of appache

It is best to publish the configuration
