How to Disable SSH Login for the Root User

In this document, we will show you to disable the SSH root login to your server.

A major security hole is to allow direct root access without any restrictions. This is an open door for hackers. They can attempt to brute force your root password and potentially get access to your server if the password can be guessed.

Quick Steps:

Login to the server via SSH.
Open the file “/etc/ssh/sshd_config” in any of your favorite text editors.
Find the section in the file containing the line with “#PermitRootLogin yes” in it.
Uncomment and change it to “PermitRootLogin no”.
Save the file and exit.
Restart the sshd service.

Disabling SSH Login for Root

The first step is to login to the server. Please note that you need to get more than one terminal access to the server because in case we lost one connection you can recover and get access to the server with the other one.

Open the SSH configuration file with your text editor.

How do I create a custom php.ini file

A custom php.ini file can be constructed and placed in your web account. For instance, using a text editor such as Notepad, you can create a php.ini file with the following custom setting which would override our default server setting:

file_uploads=off

The php.ini file should only contain the custom settings - each on it's own line (such as the above example). When completed, save the file and upload it to an area (folder) on your web account where the rest of your php files are located.

NOTE: The php.ini file should be uploaded into every folder and/or subfolder where the settings need to take place.  Be sure to rename your php.txt file to php.ini before you upload it to your server.
