LAMP stack on WSL2 (Ubuntu 20.04) - Apache, MySQL, PHP, PhpMyAdmin

Apache

sudo apt-get update && sudo apt-get upgrade 
sudo apt-get install -y apache2

PHP

sudo apt-get install -y php libapache2-mod-php
sudo apt-get install -y php-curl php-gd php-json php-mbstring php-xml

MySQL

sudo apt-get install -y mysql-server php-mysql
sudo service mysql restart
sudo mysql_secure_installation
    #> Validate password component: N
    #> New password: MyPassword
    #> Remove anonymous users: Y
    #> Disallow root login remotely: Y
    #> Reload privilege tables now: Y
sudo service mysql stop
sudo usermod -d /var/lib/mysql mysql
sudo service mysql start

Allow remote root login

sudo mysql -u root -pMyPassword  -e "UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root'; FLUSH PRIVILEGES;"

PhpMyAdmin

sudo apt-get install -y phpmyadmin
    #> Use apache2
    #> Configure db with dbconfig-common: Yes
    #> Random password (leave password blank)

sudo service mysql restart && sudo service apache2 restart

Now you can login into phpmyadmin with username root and password MyPassword.

---

Additional (optionally)

Disallow root login remotely

sudo mysql -u root -pMyPassword  -e "UPDATE mysql.user SET plugin = 'auth_socket' WHERE User = 'root'; FLUSH PRIVILEGES;"

* If remotely login for root is disallowed then you need to create new MySql user, otherwise you will not be able to login into PhpMyAdmin.

LAMP Control Aliases

cd ~ && touch .bash_aliases
echo 'alias lampstatus="sudo service apache2 status ; sudo service mysql status"' >> .bash_aliases
echo 'alias lampstart="sudo service mysql start ; sudo service apache2 start"' >> .bash_aliases
echo 'alias lampstop="sudo service mysql stop ; sudo service apache2 stop"' >> .bash_aliases
echo 'alias lamprestart="lampstop ; lampstart"' >> .bash_aliases

Now you need to logout/login and then you can use lampstatus, lampstart, lampstop and lamprestart for controling LAMP stack.

Change document root of Apache2

In this example document root will be changed from /var/www/html to ~/www

cd ~
mkdir www
sudo sed -i "s;/var/www;$HOME/www;g" /etc/apache2/apache2.conf
sudo sed -i "s;/var/www/html;$HOME/www;g" /etc/apache2/sites-available/000-default.conf

Now you can go to ~/www and create index.html

Configure Apache2 for Wordpress module rewrite custom permalink structure

First with cd go into your wordpress installation folder and then:

sudo touch .htaccess
sudo chown -v :www-data .htaccess
sudo chmod -v 664 .htaccess
sudo sed -i "s/AllowOverride None/AllowOverride All/g" /etc/apache2/apache2.conf
sudo a2enmod rewrite
sudo service apache2 restart

Now go to WpAdmin -> Settings -> Permalinks. Choose permalink structure and hit "Save Changes". Now .htaccess should be populated with wordpress rewrite rules and conditions.

NOTES --
MySQL:
1.
You may see:
"su: warning: cannot change directory to /nonexistent: No such file or directory"
after running sudo service mysql restart

• don't worry this is fixed later with sudo usermod -d /var/lib/mysql mysql

when you run mysql_secure_installation, you may see:
“Failed! Error: SET PASSWORD has no significance for user ‘root’@’localhost'”

• First open a second terminal and run:
  sudo killall -9 mysql_secure_installation
• then run:
  sudo mysql
• type the following at the mysql> prompt:
  ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YOUR_PASSWORD';
• press enter
• type "exit"
• run sudo mysql_secure_installation again and use the password you just set

Allow remote login:
sudo mysql -u root -pMyPassword -e "UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root'; FLUSH PRIVILEGES;"
gave the following error/warning:
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
what worked:
sudo mysql -u root -p [press enter, then enter password]

• at the mysql> prompt, type:
  UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root'; FLUSH PRIVILEGES;
• Press enter, type "exit"

--- accessing phpmyadmin via web browser ---

• copy the phpmyadmin.conf to apache's conf-available directory:
  sudo cp /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf

• enable the configuration:
  sudo a2enconf phpmyadmin

• restart apache2:
  sudo service apache2 restart

• change the $dbserver value in config-db.php
  sudo nano /etc/phpmyadmin/config-db.php
  --- change:
  $dbserver='localhost';
  to
  $dbserver='127.0.0.1';

• restart apache2:
  sudo service apache2 restart

• go to localhost/phpmyadmin

• you can now login with user: root and the password you set during the phpmyadmin setup

Thank you

cannot make work virtual hosts. localhost/site works though. But site.dev doesn't

Me encanto este paso a paso si se toma el tiempo para entender todos los comandos es lo que que e podido encotrar en interner

Segui todos os passos do guia, no entanto não consegui logar como root e com a senha que configurei.
Então, para resolver esse problema, editei o arquivo CONFIG.INC.PHP em /etc/phpmyadmi, removendo o comentário em , removi isso -> "//", $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

Assim consegui logar como ROOT sem o uso de senha e criei outro usuário no banco de dados para o phpmyadmin, logo após voltei a colocar o comentário: //$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
