How To Install phpMyAdmin on Ubuntu 18.04

phpMyadmin is a web-based GUI (graphical user interface) that allows administrators to create, store and edit databases that are created with MySQL. While you can interact directly with the system console from the MySQL prompt, having a GUI is preferred by some database administrators.

Before we start with the installation process, we will need some basic steps completed:


  • Connect to the server via SSH
  • A root user or a user with root privileges
  • MySQL database server up and running
  • A complete installation of LAMP stack on Ubuntu

Installing phpMyAdmin

phpMyAdmin is available through the official Ubuntu repository. However, it is recommended to update the repository to the latest version before installing phpMyadmin. To update the system:

sudo apt update

now, enter the following code to install phpMyAdmin on your system. When prompted to continue, don’t forget to press hen prompted to continue, don’t forget to y.

sudo apt install phpmyadmin php-mbstring php-gettext

You will be presented with the following screen. Be sure to select apache2 and press enter.

Note that the red highlighter does not select apache 2, you will need to press Spacebar and then press Enter. If you miss this step, the files needed for installation will not be transferred properly.

The next part of the installation will be presented with a screen as seen below. Select Yes and press Enter.

You will be prompted to enter a new password. Enter the password and confirm the password in the next window and press Enter.

Once the installation is finished, it will automatically add a phpMyAdmin configuration file in this location /etc/apache2/conf-enabled/phpmyadmin.conf.

Now, everything is set and all is left is to activate the PHP mbstring extension. You can do this by:

sudo phpenmod mbstring

Don’t forget to restart the service so that all the changes made will be properly applied to the system.

sudo systemctl restart apache2

Once the installation completes, you should now be able to point your browser to http://SERVER_IP/phpmyadmin (where SERVER_IP is the IP address of your hosting server) and log in.

Managing user access privileges

During the installation process, a database user known as phpmyadmin was created. However, instead of logging in using this user with the administrative password that was set during installation, it’s recommended to log in using a different user. You can log in as either your root MySQL user or a user dedicated to managing databases through the phpMyAdmin web interface.

You can configure both these users which will be covered in the coming steps starting from the root account.

Configure the MySQL root account for phpMyAdmin

The root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. This is a good security practice, but it complicates things when allowing external programs to access the user (like phpMyAdmin).

In order to log in to phpMyAdmin as your root MySQL user, you will need to switch its authentication method from auth_socket to mysql_native_password if you haven’t already done it so.

Enter the following commands:

sudo mysql

Now check the current authentication method of your MySQL user accounts:

SELECT user,authentication_string,plugin,host FROM mysql.user;

| user             | authentication_string                     | plugin                | host      |
| root             |                                           | auth_socket           | localhost |
| mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *8486437DE5F65ADC4A4B001CA591363B64746D4C | mysql_native_password | localhost |
| phpmyadmin       | *5FD2B7524254B7F81B32873B1EA6D681503A5CA9 | mysql_native_password | localhost |
5 rows in set (0.00 sec)

As seen above, the root user has the authentication type as auth_socket. To change it enter the following command:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

Note that, instead of the password you should enter a password that you will remember. Once this command is run, confirm the changes using the flush command.


Check the authentication methods again:

SELECT user,authentication_string,plugin,host FROM mysql.user;

You will see the output with the authentication method changed for the root user.

| user             | authentication_string                     | plugin                | host      |
| root             | *DE06E242B88EFB1FE4B5083587C260BACB2A6158 | mysql_native_password | localhost |
| mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *8486437DE5F65ADC4A4B001CA591363B64746D4C | mysql_native_password | localhost |
| phpmyadmin       | *5FD2B7524254B7F81B32873B1EA6D681503A5CA9 | mysql_native_password | localhost |
5 rows in set (0.00 sec)

Configure the MySQL user account for phpMyAdmin

If you don’t want to use the root account, then we will need to create a user account specifically for this purpose. We will need to login into the MySQL shell once again.

sudo mysql

NOTE: If you have password authentication enabled, as described in the previous section, you will need to use a different command to access the MySQL shell.

mysql -u root -p

Create a new user with a unique password (remember to replace your username and password with your new user password).

CREATE USER 'username' @ 'localhost' IDENTIFIED BY 'password';

Now to grant the permissions, enter the following command:

GRANT ALL PRIVILEGES ON *. * TO 'username' @ 'localhost' WITH GRANT OPTION;

That’s all. You can exit the MySQL prompt by entering:


Access phpMyAdmin

Once the installation completes, you should now be able to point your browser to:


Here SERVER_IP is the IP address of your hosting server. You can log in using the root user or the newly created user. If the server was set up correctly you will see a web page similar to the one below.

Once you click on Go, you will be redirected to the phpMyAdmin dashboard as seen below.

Adding the proper security configurations

phpMyAdmin is a popular target for attackers, and you should take extra care to prevent unauthorized access. One of the easiest ways of doing this is to place a gateway in front of the entire application by using Apache’s built-in .htaccess authentication and authorization functionalities.

The easiest way to prevent these attacks is to add an access port to the entire application using an integrated Apache function.

In order to do this, we will need to access the configuration file using the nano command:

sudo nano /etc/apache2/conf-available/phpmyadmin.conf

You will need to scroll down to this section < Directory / usr / share / phpmyadmin> and add the following text afterwards:

 AllowOverride All

Save and close the file. To implement all the changes, restart Apache:

sudo systemctl restart apache2

Now you have successfully enabled .htaccess for your application. The next step is to create it and implement the additional security measure.

You can create the file by entering the following.

sudo nano /usr/share/phpmyadmin/.htaccess

Enter the following data inside the file. Once done, don’t forget to the save the file and exit the text editor.

AuthType Basic
AuthName "Confined Files"
AuthUserFile /etc/phpmyadmin/.htpasswd
Require valid-user

A brief explanation of the above text:

  • AuthType Basic: This will implement password authentication using a password file.
  • AuthName: This sets the message for the authentication dialog box.
  • AuthUserFile: This sets the location of the password file that will be used for authentication.
  • Require valid-user: This specifies that only authenticated users should be given access to this resource. This is what actually stops unauthorized users from entering.

Now let’s create a password file:

sudo htpasswd -c /etc/phpmyadmin/.htpasswd username

Replace the username with a name of your choice. You will need to add a password for the user you are creating and then the file will be created.

Now when you will log in to the server, there will be an additional username and password set in place as a security measure.

Enter the credentials and then you will be greeted with the normal phpMyAdmin login window.

Wrapping up

During this tutorial, we went through the process of configuring phpMyAdmin on the Ubuntu 18.04 server. By adding this, the system administrator will have a web-based interface to work directly with the MySQL databases instead of using the console.

We also added .htaccess as an additional security measure for our server. If you will come across any problems, feel free to contact us through the dedicated comment section below.
