Скачать или смотреть How to install LAMP stack (Linux, Apache, MySQL, PHP) on Ubuntu 20.04

Install Apache on Ubuntu 20.04 by running
apt install apache2
after install MySQL server
apt install mysql-server
secure your MySQL server by running
mysql_secure_installation
follow onscreen instructions to set your root password and disable remote login.
Install PHP by running
apt install php libapache2-mod-php php-mysql

Create directories for the new sites:
mkdir /var/www/site1
mkdir /var/www/site2

Create config files and add:
nano /etc/apache2/sites-available/site1.conf
with (don't forget to add VirtualHost *:80 between brackets and the ending VirtualHost as in the video):

ServerName site1.tut
ServerAlias www.site1.tut
ServerAdmin [email protected]
DocumentRoot /var/www/site1
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

for the 2nd site:
nano /etc/apache2/sites-available/site2.conf
with (don't forget to add VirtualHost *:80 between brackets and the ending VirtualHost as in the video):

ServerName site2.tut
ServerAlias www.site2.tut
ServerAdmin [email protected]
DocumentRoot /var/www/site2
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

Enable the new config files:
a2ensite site1
a2ensite site2

Disable old config by running: a2dissite 000-default

Now you can add your site file in /var/www/site1 for the first one and in /var/www/site2 for the second website.

If you need additional post in comments and I will try to respond asap.

Thanks!
