How To Install phpMyAdmin On Ubuntu

Managing MySQL, MariaDB and other databases via the command line is not easy, especially for those who are not particularly familiar with Linux. In this article, I will tell how you can install phpMyAdmin on your ubuntu server and create new databases visually through it. And you can use these databases in your CMS project and other web app projects.

What is phpMyAdmin?

phpMyAdmin is a free and open-source software/tool for managing MySQL and MariaDB. This tool is written in PHP, and it is the most popular database administration tool, especially for web hosting services. phpMyAdmin is primarily comes preinstalled with shared web hosting services (like cPanel hosting).

Pre-requisites for Installing phpMyAdmin on Ubuntu

Before installing phpMyAdmin on Ubuntu or Debian system, you must make sure that some required components are installed. However, you can download the package without the required elements, but you cannot configure without them.

  1. Apache Web Server
  2. MySQL/MariaDB
  3. PHP 7.4.x or above (for best performance)

Apache2 web server is required to make HTTP protocol, so we can access phpMyAdmin using a web browser, and you also need pre-installed MySQL or MariaDB database to manage other databases or create a new one. Although, if you are thinking to create a web project based on PHP language, then you should also install the latest version of PHP, that is PHP 8.0.

Steps of Installing phpMyAdmin on Ubuntu

As I have already mentioned, you must install an Apache web server, MySQL or MariaDB database, and PHP. If you have not installed these packages in the system, you can follow the LAMP stack installation method or execute the following command to install these pre-requisites software.

Install Pre-requisites components

Update system:

sudo apt update -y && apt upgrade -y

Install Apache, PHP, and MySQL (MariaDB) database:

sudo apt install apache2 && apt install php-cli && apt install mariadb-server

When you execute the command, the system will prompt you to “Do you want to continue?” several times. You have to type “Y” and then ENTER on the keyboard. Your Apache server, PHP, and Database installation are complete, but you must start the services by running the command. Sometimes these services run automatically after installing packages.

Start Apache Webserver:

sudo service apache2 start

Start MySQL Database:

sudo service mysql start

Secure MySQL/MariaDB

Before installing phpMyAdmin and configuring it, you must secure the MySQL/MariaDB database, using the following command.

sudo mysql_secure_installation

When you execute the command, the system will ask some questions, and you must give the answers according to the list below.

  • Enter current password for root (enter for none): Press ENTER key
  • Set root password? [Y/N]: Y
  • New password: Type your password
  • Re-enter new password: Type your password again
  • Remove anonymous users? [Y/N]: Y
  • Disallow root login remotely? [Y/N]: Y
  • Remove test database and access to it? [Y/N]: Y
  • Reload privilege tables now? [Y/N]: Y

Install phpMyAdmin & Configure

After securing the MySQL database, you must execute the following command to install latest version of phpMyAdmin in Ubuntu server.

sudo apt install phpmyadmin
install phpmyadmin

Select web server:

select server for phpmyadmin

Auto configure phpMyAdmin:

configure phpmyadmin with dbconfig-common tool

Enter Password for phpMyAdmin:

set phpmyadmin database password

Re-enter phpMyAdmin password:

reenter phpmyadmin database password

Login to phpMyAdmin

After installing phpMyAdmin successfully, you have to login phpMyAdmin dashboard. However, you could face some possible error. But I am also rectifying all the possible error, during installation or after the installation.

So, open your web browser and visit http://your_ip_address/phpmyadmin and in case you are installing phpMyAdmin in a local machine, then visit http://localhost/phpmyadmin.

login to phpMyAdmin

Suppose you configure phpMyAdmin using the automatic method as the tutorial. In that case, it automatically creates a new database named ‘phpmyadmin’ and the user also ‘phpmyadmin.’ So, login with the user name ‘phpmyadmin’ and the password made earlier.

phpMyAdmin dashboard

Possible error while/after configuring phpMyAdmin

After installing the phpMyAdmin in the Ubuntu server, you may face some errors like 404 not found and no privileges to create a database or Access denied for the root login. So, in this article, I am going to resolve all the issues.

404 Not Found

404 not found phpmyadmin

If you get a 404 not found error when you visit the phpMyAdmin URL, that means your Apache server configuration with phpMyAdmin is not fully configured. For completing the setup or resolving the error, you must edit apache.conf file.

sudo nano /etc/apache2/apache2.conf

Use nano to edit apache.conf file and add the following line in the last.

Include /etc/phpmyadmin/apache.conf

After adding the line, you must restart the Apache server and open the URL, and phpMyAdmin will work.

sudo service apache2 restart

Access denied for user ‘root’@’localhost.’

Access Denied

If you try to login with root, it possible that phpMyAdmin will show the access denied error. Cause the phpMyAdmin configuration. First, you have to give full privileges to the root user upon phpmyadmin database and then change the username on phpMyAdmin.

Login to MySQL:

sudo mysql -u root -u

When you execute the command system will prompt you to enter your MySQL root password.

Give full privileges to the root user upon phpmyadmin:

GRANT ALL PRIVILEGES ON phpmyadmin.* TO [email protected] IDENTIFIED BY 'password';

After login to MySQL, you have to execute the following command to give full privileges to root user. As you can see the password on the command you have to put your MySQL password.

FLUSH PRIVILEGES;
exit;

Now flush the privileges and then execute exit command to quit MySQL cli.

Edit config-db.php:

nano /etc/phpmyadmin/config-db.php
edit config-db-php

When you execute the command to edit config-db.php, the terminal will open a GNU nano editor, and you will see $dbuser as phpmyadmin. So, you must change it to ‘root’ from ‘phpmyadmin,’ as you can see in the image above.

Root privileges dashboard of phpMyAdmin:

root privileges databases

Now, successfully configuring the phpMyAdmin, you can log in with your root username and password. And as you can see from the image of the phpMyAdmin dashboard, you will access all databases, and you can create new databases.

Conclusion

So, that was the easiest method to install phpMyAdmin in your Ubuntu server, and this method also works with other version of Ubuntu server, and with Debian operating system. If you face any other issues please let us know in the comment box.
