Install WordPress on Ubuntu 16.04 LTS with Nginx, MariaDB and PHP 7.1 Support
If you’re not using WordPress to run your PHP based websites or blogs, you should highly consider it…
WordPress, the most powerful and popular content management systems (CMS) is the right tool to develop and build powerful and dynamic websites based on PHP…
With PHP 7.1 now supported, you can greatly improve its performance configured with Nginx HTTp Server… For those who are new and want to learn how to install WordPress on Ubuntu running Nginx with PHP 7.1, the steps below should be a great starting point.
This brief tutorial is going to show students and new users how to install WordPress on Ubuntu 16.04 LT with Nginx, MariaDB and PHP 7.1 support.
To get started with installing WordPress, follow the steps below:
Step 1: Install Nginx HTTP Server
WordPress requires a web server and the most popular webserver in use today is Nginx HTTP Server. So, go and install Nginx on Ubuntu by running the commands below:
sudo apt install nginx
Next, run the commands below to stop, start and enable Nginx service to always start up with the server boots.
sudo systemctl stop nginx.service sudo systemctl start nginx.service sudo systemctl enable nginx.service
Step 2: Install MariaDB Database Server
WordPress also requires a database server… and MariaDB database server is a great place to start. To install it run the commands below.
sudo apt-get install mariadb-server mariadb-client
After installing, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.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
sudo systemctl restart mysql.service
Step 3: Install PHP 7.1 and Related Modules
WordPress also requires PHP. However, PHP 7.1 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 7.1
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.1
sudo apt update
Run the commands below to install PHP 7.1 FPM and related modules.
sudo apt install php7.1-fpm php7.1-common php7.1-mbstring php7.1-xmlrpc php7.1-soap php7.1-gd php7.1-xml php7.1-intl php7.1-mysql php7.1-cli php7.1-mcrypt php7.1-zip php7.1-curl
After install PHP 7.1, run the commands below to open PHP-FPM default file.
sudo nano /etc/php/7.1/fpm/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 cgi.fix_pathinfo=0 max_execution_time = 360 date.timezone = America/Chicago
Step 4: Create WordPress Database
Now that you’ve install all the packages that are required, continue below to start configuring the servers. First run the commands below to create WordPress database.
Run the commands below to logon to the database server. When prompted for a password, type the root password you created above.
sudo mysql -u root -p
Then create a database called wordpress
CREATE DATABASE wordpress;
Create a database user called wordpressuser with new password
CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'new_password_here';
Then grant the user full access to the database.
GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;
Finally, save your changes and exit.
FLUSH PRIVILEGES; EXIT;
Step 5: 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 to function.
sudo chown -R www-data:www-data /var/www/html/wordpress/ sudo chmod -R 755 /var/www/html/wordpress/
Step 6: Configure Nginx HTTP Server
Finally, configure Apahce2 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
sudo nano /etc/nginx/sites-available/wordpress
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.
server {
listen 80;
listen [::]:80;
root /var/www/html/wordpress;
index index.php index.html index.htm;
server_name example.com www.example.com;
client_max_body_size 100M;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
Save the file and exit.
Step 7: Enable the WordPress and Rewrite Module
After configuring the VirtualHost above, enable it by running the commands below… the commands also disable PHP7.0 and enable PHP 7.1 for Nginx.
sudo ln -s /etc/nginx/sites-available/wordpress /etc/nginx/sites-enabled/
Step 8 : Restart Nginx
To load all the settings above, restart Nginx by running the commands below.
sudo systemctl restart nginx.service
STEP 9: CONFIGURE WORDPRESS
Now that Nginx 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', 'wordpress'); /** MySQL database username */ define('DB_USER', 'wordpressuser'); /** 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', '');
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.
http://example.com

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

This should install WordPress.

You saved my life !
I followed so many instructions on the net but not worked.
Thank you so much !!!
Hi,
I’m not able to create a new username. I perfectly followed your instructions but I get this
Query OK, 0 rows affected (0.00 sec)
The command looks good
Excellent! After spending several hours on other websites (including DO and others) finally was able to successfully deploy!
In case after the server reboot you get “White Page of Death”, which is actually internal server error 500 you can try checking NGINX error log, in my case it was here
/var/log/nginx/error.log
FastCGI sent in stderr: “PHP message: PHP Fatal error: Allowed memory size of 2097152 bytes exhausted
After several hours of digging the only thing that helped to bring the page back to normal was to add memory limit here:
/var/www/html/wordpress/wp-settings.php
just add the following line somewhere, (probably 1024M is an overkill):
ini_set(‘memory_limit’, ‘1024M’);
for php7.1-fpm:
sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 4F4EA0AAE5267A6C
tks,very great!!!
This worked for me too. The only step left out was that I had to remove the default from ‘sites-available.’
