Install WordPress on Ubuntu 16.04 | 17.10 | 18.04 with Apache2, MariaDB, PHP 7.2 and Let’s Encrypt SSL/TLS
This brief tutorial shows students and new users how to install WordPress CMS on Ubuntu 16.04 / 17.10 and 18.04 LTS with Apache2, MariaDB and PHP 7.2 support with Let’s Encrypt free SSL/TLS enabled… {LAMP + Let’s Encrypt}
This setup will probably be how all WordPress sites will be configured going forward, since Google is strongly encouraging website owners to use SSL/TLS encryption for all web pages..
Also, WordPress is PHP 7.2 compatible.. so why not use the latest PHP? However, before using PHP 7.2, make sure all your plugins and themes are compatible or you’ll seriously run into issues..
When you’re ready to get WordPress working, continue with the steps below:
Step 1: Install Apache2 HTTP Server on Ubuntu
Apache2 HTTP Server represents the A in the LAMP stack… It’s the most popular web server in use… so install it, since WordPress needs it..
To install Apache2 HTTP on Ubuntu server, run the commands below…
sudo apt update sudo apt install apache2
After installing Apache2, the commands below can be used to stop, start and enable Apache2 service to always start up with the server boots.
sudo systemctl stop apache2.service sudo systemctl start apache2.service sudo systemctl enable apache2.service
To test Apache2 setup, open your browser and browse to the server hostname or IP address and you should see Apache2 default test page as shown below.. When you see that, then Apache2 is working as expected..

Step 2: Install MariaDB Database Server
MariaDB database server is a great place to start when looking at open source database server to use with WordPress… To install MariaDB run the commands below…
sudo apt-get install mariadb-server mariadb-client
After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots..
Run these on Ubuntu 16.04 LTS
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.service
Run these on Ubuntu 17.10 and 18.04 LTS
sudo systemctl stop mariadb.service sudo systemctl start mariadb.service sudo systemctl enable mariadb.service
After that, run the commands below to secure MariaDB server by creating a root password and disallowing remote root access.
sudo mysql_secure_installation
When prompted, answer the questions below by following the guide.
- Enter current password for root (enter for none): Just press the Enter
- Set root password? [Y/n]: Y
- New password: Enter password
- Re-enter new password: Repeat password
- 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
Restart MariaDB server
To test if MariaDB is installed, type the commands below to logon to MariaDB server
sudo mysql -u root -p
Then type the password you created above to sign on… if successful, you should see MariaDB welcome message

Step 3: Install PHP 7.2 and Related Modules
PHP 7.2 isn’t available on Ubuntu default repositories… in order to install it, you will have to get it from third-party repositories.
Run the commands below to add the below third party repository to upgrade to PHP 7.2
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.2
sudo apt update
Next, run the commands below to install PHP 7.2 and related modules.
sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-gd php7.2-xml php7.2-intl php7.2-mysql php7.2-cli php7.2-zip php7.2-curl
After installing PHP 7.2, run the commands below to open PHP default config file for Apache2…
sudo nano /etc/php/7.2/apache2/php.ini
Then make the changes on the following lines below in the file and save. The value below are great settings to apply in your environments.
file_uploads = On allow_url_fopen = On memory_limit = 256M upload_max_filesize = 100M max_execution_time = 360 date.timezone = America/Chicago
After making the change above, save the file and close out.
Step 4: Restart Apache2
After installing PHP and related modules, all you have to do is restart Apache2 to reload PHP configurations…
To restart Apache2, run the commands below
sudo systemctl restart apache2.service
To test PHP 7.2 settings with Apache2, create a phpinfo.php file in Apache2 root directory by running the commands below
sudo nano /var/www/html/phpinfo.php
Then type the content below and save the file.
<?php phpinfo( ); ?>
Save the file.. then browse to your server hostname followed by /phpinfo.php
You should see PHP default test page…

Step 5: Create WordPress Database
Now that you’ve installed all the packages that are required for WordPress to work, continue below to start configuring the servers. First run the commands below to create a blank WordPress database.
To logon to MariaDB database server, run the commands below.
sudo mysql -u root -p
Then create a database called wpdb
CREATE DATABASE wpdb;
Create a database user called wpuser with new password
CREATE USER 'wpuser'@'localhost' IDENTIFIED BY 'new_password_here';
Then grant the user full access to the database.
GRANT ALL ON wpdb.* TO 'wpuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;
Finally, save your changes and exit.
FLUSH PRIVILEGES; EXIT;
Step 6: Download WordPress Latest Release
Next, visit WordPress site and download the latest version….
After downloading, run the commands below to extract the downloaded file and move it into a new WordPress root directory.
cd /tmp && wget https://wordpress.org/latest.tar.gz tar -zxvf latest.tar.gz sudo mv wordpress /var/www/html/wordpress
Then run the commands below to set the correct permissions for WordPress direcotories.
sudo chown -R www-data:www-data /var/www/html/wordpress/ sudo chmod -R 755 /var/www/html/wordpress/
Step 7: Configure Apache2 HTTP Server
Next, configure Apache2 site configuration file for WordPress. This file will control how users access WordPress content. Run the commands below to create a new configuration file called wordpress.conf
sudo nano /etc/apache2/sites-available/wordpress.conf
Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.
<VirtualHost *:80> ServerAdmin admin@example.com DocumentRoot /var/www/html/wordpress/ ServerName example.com ServerAlias www.example.com <Directory /var/www/html/wordpress/> Options +FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>
Save the file and exit.
Step 8: Enable the WordPress Site and Rewrite Module
After configuring the VirtualHost above, enable it by running the commands below, then restart Apache2 server…
sudo a2ensite wordpress.conf sudo a2enmod rewrite sudo systemctl restart apache2.service
STEP 9: CONFIGURE WORDPRESS
Now that Apache2 is configured, run the commands below to create WordPress wp-config.php file.
sudo mv /var/www/html/wordpress/wp-config-sample.php /var/www/html/wordpress/wp-config.php
Then run the commands below to open WordPress configuration file.
sudo nano /var/www/html/wordpress/wp-config.php
Enter the highlighted text below that you created for your database and save.
// ** MySQL settings - You can get this info from your web host ** // /** The name of the database for WordPress */ define('DB_NAME', 'wpdb'); /** MySQL database username */ define('DB_USER', 'wpuser'); /** MySQL database password */ define('DB_PASSWORD', 'user_password_here'); /** MySQL hostname */ define('DB_HOST', 'localhost'); /** Database Charset to use in creating database tables. */ define('DB_CHARSET', 'utf8'); /** The Database Collate type. Don't change this if in doubt. */ define('DB_COLLATE', '');
Step 10: Install Let’s Encrypt Client
To get Let’s Encrypt free SSL/TLS certificates on your Ubuntu machine, you should first install its client. The client helps automate the process for you. To install it, run the commands below.
sudo apt-get install python-certbot-apache
Step 11: Obtaining your free SSL/TLS Certificates
After installing Let’s Encrypt Certbot client module for Apache2, run the commands below to obtain your free Let’s Encrypt SSL/TLS certificate the domain specified… make sure to replace example.com with your own domain..
sudo certbot --apache -m admin@example.com -d example.com -d www.example.com
After running the above commands, you should get prompted to accept the licensing terms. If everything is checked, the client should automatically install the free SSL/TLS certificate and configure the Apache2 site to use the certs.

This is how easy is it to obtain your free SSL/TLS certificate for your Apache2 powered website.
Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access. ------------------------------------------------------------------------------- 1: No redirect - Make no further changes to the webserver configuration. 2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for new sites, or if you're confident your site works on HTTPS. You can undo this change by editing your web server's configuration. ------------------------------------------------------------------------------- Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2
Pick option 2 to redirect all traffic over HTTPS. This is important!
After that, the SSL client should install the cert and configure your website to redirect all traffic over HTTPS.
Congratulations! You have successfully enabled https://example.com and https://www.example.com You should test your configuration at: https://www.ssllabs.com/ssltest/analyze.html?d=example.com https://www.ssllabs.com/ssltest/analyze.html?d=www.example.com ------------------------------------------------------------------------------- IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at: /etc/letsencrypt/live/example.com/fullchain.pem Your key file has been saved at: /etc/letsencrypt/live/example.com/privkey.pem Your cert will expire on 2018-02-24. To obtain a new or tweaked version of this certificate in the future, simply run certbot again with the "certonly" option. To non-interactively renew *all* of your certificates, run "certbot renew" - If you like Certbot, please consider supporting our work by: Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate Donating to EFF: https://eff.org/donate-le
The highlighted code block should be added to your Apache2 WordPress configuration file automatically by Let’s Encrypt certbot. Your WordPress site is ready to be used over HTTPS.
<VirtualHost *:80> ServerAdmin admin@example.com DocumentRoot /var/www/html/wordpress/ ServerName example.com ServerAlias www.example.com <Directory /var/www/html/wordpress/> Options +FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined RewriteEngine on RewriteCond %{SERVER_NAME} =example.com [OR] RewriteCond %{SERVER_NAME} =www.example.com RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent] </VirtualHost>
A new configuration file for the domain should also be created named /etc/apache2/sites-available/example.com-le-ssl.conf. This is Apache2 SSL module configuration file and should contain the certificate definitions defined in it.
<IfModule mod_ssl.c> <VirtualHost *:443> ServerAdmin admin@example.com DocumentRoot /var/www/html/wordpress/ ServerName example.com ServerAlias www.example.com <Directory /var/www/html/wordpress/> Options +FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem Include /etc/letsencrypt/options-ssl-apache.conf </VirtualHost> </IfModule>
You’ll have to manually renew the certificates. You’ll get email reminder to reset when the certificates are about to expire. To test the renewal process run the commands below.
sudo certbot renew --dry-run
To setup a process to automatically renew the certificates, add a cron job to execute the renewal process.
sudo crontab -e
Then add the line below and save.
0 1 * * * /usr/bin/certbot renew & > /dev/null
The cron job will attempt to renew 30 days before expiring
After that, open your browser and browse to your domain name to launch WordPress configuration wizard.
You should see WordPress setup wizard to complete. Please follow the wizard carefully.

Then type the WordPress website name and create a new admin user and password.. the click install.

This should install WordPress.

Congratulations! You’ve successfully installed WordPress on Ubuntu with Apache2, MariaDB, PHP 7.2 with Let’s Encrypt free SSL/TLS certificates
