Wordpress

PHP

Note: All these are needed(installed) by the web server OR PHP CLI

Install the PHP metapackage (not web server)
sudo apt install php -y

Installs the MySQLi (MySQL Improved) extension for PHP.Allows PHP scripts to interact with MySQL databases. Newer version (e.i object orient support).
sudo apt install php-mysqli

Installs the MySQL extension for PHP (the php-mysql module). Allows PHP scripts to interact with MySQL databases with MySQL/MariaDB databases. Legacy version.
sudo apt install php-mysql
Note:This is NOT the php that the Apache Web Server uses but the MySQL extension for PHP

(For more indepth installation of CLI PHP)

Web Server

For installation of Apache or nginx
(Make sure that php code can execute on Web Server – Decide between apache php module or FPM-PHP)

Install Apache
sudo apt install apache2 apache2-doc apache2-utils -y

Verify that Apache is running
systemctl status apache2

(After installation go to ip address where Apache Server is installed and the welcome page for apache should be displayed)
Install the package for apache php module
sudo apt install libapache2-mod-php -y
Note: sudo apt install libapache2-mod-php8.2 -y

Enable the apache php module
sudo a2enmod php8.2

Restart Apache
systemctl restart apache2
Create a php file and put it the same folder as default index.html, usually /var/www/html and se if webserver executes php code

Install and configure WordPress

There are 2 ways of installing wordpress, manually by downloading wordpress or by using the package manager supplied by Linux OS (our case here debian)

Install and enable rewrite module (for SEO in wordpress)

(Not mandatory but recommended that the rewrite module is installed and enabled)
11.a) Is the rewrite module installed
cd /etc/apache2/mods-available
List content – should be named rewrite.load. PS The module should be installed as default with apache
ls -la

b) Is the rewrite module enabled
cd /etc/apache2/mods-enabled
List content – should be present and named rewrite.load.
ls -la
If this module not found then enable and restart the apache2 server
sudo a2enmod rewrite && sudo systemctl stop apache2 && sudo systemctl start apache2

Manuell installation of WordPress

1. Go to homefolder
cd ~

2. Download wordpress
wget https://wordpress.org/latest.tar.gz

3. Extract the tar ball
tar xpf latest.tar.gz

4.Now we want to put the wordpress in the html folder of wordpress
a) Remove all content i html folder
sudo rm -fr /var/www/html

b) Copy the content of wordpress directory into the html directory
sudo cp -r wordpress /var/www/html

5. Change some ownerships for html folder and everything withing that folder
sudo chown -R www-data:www-data /var/www/html

6. Change some permissions on folder and files
a) For folder/directories
sudo find /var/www/html -type d -exec chmod 755 {} \;

b) For files
sudo find /var/www/html -type f -exec chmod 644 {} \;

8. Restart the apache web server
sudo systemctl stop apache2 && sudo systemctl start apache2

9. Go to the domain or ip adress and there you will be greated by the wordpress installtion page
During that installation you will create a wordpress user AND also need to specify the database connection details(when we created the database – database,user,password,host).
This information will be stored in wp-config.php file later. After this procedure wordpress is up and running

Install through the package manager – Debian(Not recommended)

(PS Debian WordPress Version Lacks way behind the official one. Sometimes not even possible to install WooCommerce)
1. Install the wordpress package
sudo apt install wordpress

2. Create the site
nano /etc/apache2/sites-available/wp.conf

a). With the content

<VirtualHost *:80>
# ServerName myblog.example.com
ServerName 167.71.13.64

ServerAdmin webmaster@example.com
DocumentRoot /usr/share/wordpress

Alias /wp-content /var/lib/wordpress/wp-content
<Directory /usr/share/wordpress>
   Options FollowSymLinks
   AllowOverride Limit Options FileInfo
   DirectoryIndex index.php
   Require all granted
</Directory>
<Directory /var/lib/wordpress/wp-content>
   Options FollowSymLinks
   Require all granted
</Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

OR
b)

<VirtualHost *:80>
ServerAdmin webmaster@genixtryout.win
ServerName genixtryout.win
ServerAlias www.genixtryout.win

# Needed for apache that allows .htaccess file to override setting
# Should be the folder where wordpress is located
# Settings are applied to this directory
<Directory /var/www/html/>
   # Allows apache to follow symbolik links
   Options FollowSymLinks
   # Most important, else wordpress permalinks do NOT work
   AllowOverride All
   #Grant all user to access the content of the directory
   Require all granted
</Directory>

ErrorLog /var/www/logs/error.log
#ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog /var/www/logs/access.log combined
#CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

3. Disable the default site and enable the one created in the step 2.
Disable the default site – usually /etc/apache2/sites-available/000-default.conf
a2dissite 000-default

Enable the new site – Same name as specified in step 2
a2ensite wp

4. Create the default config file. Here debian is DIFFERENT from all others.
replace myblog.example.com with what you entered in the ServerName (ip or domain). NOT nano /etc/wordpress/config-myblog.example.com.php
BUT
nano /etc/wordpress/config-167.71.13.64.php
And enter this to the file. Use it as a template

5. Reload the server
systemctl stop apache2 && systemctl start apache2

TO BE CONTINUED!

Go to the domain or ip adress and there you will be greated by the wordpress installtion page. During installation the you will create a wordpress user and may need to specify the database connection.
