To disable SSLv3 support for Apache you need to look for the ssl configuration file (in Centos it is at /etc/httpd/conf.d/ssl.conf) and modify the SSLProtocol line:
SSLProtocol all -SSLv2 -SSLv3
You can also add the line after SSLEngine On in a Virtual Host file.
Just be aware that old versions of Internet Explorer (<=6) do not have TLS enabled by default so any users still using this version will be left out in the cold.
