Replace MySQL with MariaDB on CentOS

MariaDB is an enhanced, drop-in replacement for MySQL offering many speed improvements intended to remain free under the GNU GPL. MariaDB version numbers, up to 5.5, followed MySQL’s numbers. Thus, if one uses MariaDB 5.5 one knows that all features from MySQL 5.5 are available. After version 5.5, MariaDB developers decided to start a branch numbered 10, as an attempt to make it clear that MariaDB 10.0 will not import all features from MySQL 5.

Set up NginX and Varnish with Apache in Sentora

By default, Sentora, as well as Sentora, comes with Apache 2.2 and I feel that it’s a bad solution when there are many good solutions already for using as web server e.g. Litespeed, NginX, Lighttpd etc. Litespeed is a paid service so I never use it at all. If you have the ability to pay for it, you should use it as it is very good as far as I see on Benchmark test results.

cPanel Bandwidth problem solution

Hello readers! After a long time I am back with a new topic. Today I am going to discuss about cPanel bandwidth problem. The websites on your server may use heavy traffic but cPanel bandwidth counter always show that they are using a low bandwidth. Then you can understand that cPanel can’t count bandwidth correctly. Actually we get this issue when we try to use Nginx/Varnish as a web-proxy in front of Apache.

Change SSH port on your CentOS server

When you install CentOS on your server then your default SSH port is 22. It’s default, I mean, all servers with CentOS operating system normally have port 22 opened. Any hacker may flood this port or try to connect via this port and can do any harm to the server. So the better practice is to change the port. Though it can’t do much for you, but I believe that it’s quite impossible to find out a SSH port for a hacker where the appropriate range is too long to guess the correct port.

Change WHM Nameserver IPs

If you are using a VPS and you have cPanel installed on it, then you may need to update or change WHM Nameserver IPs for various reasons. If you simply try to change it, you will find that they are not changing accurately. For this, you have to do it manually I mean you may do it by command. Login to your server via SSH, you need to log in as root.
