comment Is it possible to configure CPanel to run only eith Nginx
I'm not exactly sure I've only used CPanel once and from my experience it's coupled with Apache very tight. So I guess even if it is possible it's not so easy.

comment Apache 2 Settings for high traffic webserver
MaxClients 1000 - this setting is dangerous, 1000 Apache workers will effectively utilize virtually any amount of server's RAM. Your setting should be more realistic.

comment Would Sphinx be a good solution to solve server getting bogged with heavy MySQL reads?
Are you absolutely sure these queries use indexes properly? You can check this using the EXPLAIN command in mysql console. If they do you should probably extend max MySQL key buffer size in the config.

There should be an application server behind them, like Apache or PHP-FPM, nginx is only a reverse proxy by nature. It uses HTTP or FastCGI to talk to backends.

comment With HTTPS-Enforcer chrome extension, a normal ping is answered by different site
Okay it's obvious now that your system uses a custom DNS server installed on it (namserver is set to the default local address 127.0.0.1). Again, 67.215.65.132 is NOT a github site of that plugin, it is one of the OpenDNS IP addresses according to its whois info (you can check this using whois 67.215.65.132). The easiest way to fix it temporarily is to edit /etc/resolv.conf manually and to replace nameserver 127.0.0.1 with nameserver 8.8.8.8 (8.8.8.8 is a Google public DNS). To make this fix permanent you should consult resolvconf manual, I'm not a big expert here.

Apache should have at least x permission on your folder to be able to work with its subfolder.

Does Apache user have rights to access this subfolder in your home folder? You can check using sudo su - your-apache-user and then using ls /home/your_user/path/to/your/subfolder

comment Mysql - Performance improvement of “ORDER BY” with index
No it won't be useful then, the only optimization I can think of in that case is to select not * but primary keys only and use a LIMIT clause (I guess a user never needs the whole table). When you get the primary keys you will be able to get everything else in separate query like SELECT * FROM t1 WHERE pk IN (.., .., ..). Queries like SELECT * WHERE some_complex_expression ORDER BY ... effectively kill MySQL sorting buffers, it's always better to sort less data and * can be a lot of data.

Why do you need to repair the database tables every time? What storage engine do you use?
