In todays world when everything is going online and has almost gone online, it is very important to secure web applications. Apache web server is the most common server used to serve resources such as entire website, music files, movies etc in web programming.

Following are some points :

  1. Firstly and most important always use HTTPS in your website's url because it provides an extra layer of protection in addition of username and password.

  2. Secondly, always change the url of your phpmyadmin. By default it is always 'http://ip_address/phpmyadmin' so make sure you change and make it some appropriate url so that it is difficult to assume. Following are the steps to change phpmyadmin url in Linux :

    • Connect to your server via ssh utility.

    • edit /etc/phpmyadmin/apache.conf, for that type

      nano /etc/phpmyadmin/apache.conf

For eg. Alias /rwma1THi2WWC /usr/share/phpmyadmin

    • Done.

  4. Always use a strong password for login with a combination of alphabets, numbers, special chars and upper case letters.

  5. Always give permissions to users who are reliable. You can manage permissions like listed below :
