[SOLVED] - Install phpMyAdmin & LAMP on Ubuntu 20.04 Desktop

Install phpMyAdmin & Linux, Apache, MySQL/MariaDB & PHP [LAMP] on Ubuntu 20.04 desktop.

Below you will find the instructions that I myself have tried and successfully implemented on my system.

 1. Install Apache Web Server

 sudo apt update  
 sudo apt install apache2  

2. Install MariaDB

 sudo apt install mariadb-server  
 sudo apt install mariadb-client  

After that, run the commands below to secure the MariaDB server by creating a root password, disallowing remote root access removing anonymous, and more.

 sudo mysql_secure_installation  

 If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here.  
 Enter current password for root (enter for none): PRESS ENTER  
 Switch to unix_socket authentication [Y/n] n  
 Change the root password? [Y/n] n  
 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  
 All done!  

3. Install PHP

 sudo apt install php7.4 php7.4-common php7.4-mysql php7.4-gmp php7.4-curl php7.4-intl php7.4-mbstring php7.4-xmlrpc php7.4-gd php7.4-xml php7.4-cli php7.4-zip  

4. Install phpMyAdmin

 sudo apt install phpmyadmin  

When prompted to choose the web server, select apache2 and continue.

   

When prompted again to allow web config-common to install a database and configure select Yes and press ENTER.

Then type and confirm a password.

After installing phpMyAdmin, open your web browser and browse to the server hostname or IP address followed by /phpmyadmin.

 http://localhost/phpmyadmin  

If you encounter the following error implement the solution below to resolve the issue:

ERROR: mysqli_real_connect(): (HY000/1698): Access denied for user 'root'@'localhost'

Open your terminal and run the following commands:

 sudo mysql -u root  

 use mysql;  
 update user set plugin='' where User='root';  
 flush privileges;  
 \q  

Now the LAMP cum phpMyAdmin should be working for you.

If you are unable to suspend your laptop, here's the solution which I've tried & tested and it worked with my Lenovo Thinkpad T440.

 Open your terminal and enter the following commands:

>> Steps 1: Create backup of the following file 'logind.conf':

 sudo cp /etc/systemd/logind.conf /etc/systemd/logind-backup.conf

 sudo vi /etc/systemd/logind.conf  

 >> Steps 3: Step 3: Carefully navigate and make sure the following lines are changed to look like shown below. If the lines are commented (Example: #HandleSuspendKey=suspend), uncomment them.

 HandleSuspendKey=suspend  
 HandleLidSwitch=suspend  
 HandleLidSwitchDocked=suspend  

 >> Steps 4: Save the file.

 >> Steps 3: Reboot & check. You can reboot from the terminal using the following command:

[Solved] - How to Find Composer Name of Mageplaza Paid Extensions - Magento 2

Don't know why Mageplaza haven't still listed the composer name of their paid extensions. Look at the comment section of this tutorial: https://bit.ly/2Z9P7jC; you will see users asking for composer name, and still no solution is provided by them. Today I tried posting this solution as a comment in the aforementioned page, and each time my comment got deleted for reasons unknown to me. That's why I have decided to post this solution here.

The solution is very simple. Just download the extension, and look in the composer.json file. You will see a key/value pair entry as follows:

  "name": "mageplaza/module-search"  

Here module-search is the composer name of the paid extension Ajax Search for Magento 2.

NOTE: If you are installing Mageplaza extensions for the first time via composer, make sure to run the following command first:

 $ composer config repositories.mageplaza composer https://repo.mageplaza.com
