Installing Nginx, MariaDB on Ubuntu 16.04 / 17.10 / 18.04 with PHP 7.2 Support (LEMP)

LEMP is an acronym for Linux, Engine-X (Nginx), MariaDB or MySQL and PHP… It’s the building block for majority of the content management systems in use today, like WordPress, Joomla, Drupal and many more…

If you’re going to be developing any PHP based applications or websites with support for Nginx and MariaDB, then you’re going to probably need the latest version of PHP installed…

With PHP 7.2 released, you can now include the latest PHP version with your stack to improve the performance of the sites and applications… This brief tutorial is going to show students and new users how to install Nginx, MariaDB and PHP 7.2 on Ubuntu Linux 16.04, 17.10 and 18.04 LTS server.

To get started with install LEMP with PHP 7.2 support, follow the steps below:

Step 1: Install Nginx HTTP Server on Ubuntu

Nginx HTTP Server represents the E in the LEMP stack… It’s probably the second most popular web server installed today not far behind Apache2…

To install Nginx HTTP on Ubuntu server, run the commands below…

sudo apt update
sudo apt install nginx

After installing Nginx, the commands below can be used 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

To test Nginx setup, open your browser and browse to the server hostname or IP address and you should see Nginx default test page as shown below.. When you see that, then Nginx is working as expected..

ex.. http://localhost

Nginx ssl ubuntu

Step 2: Install MariaDB Database Server

MariaDB database server is a great place to start when looking at open source database server… Although MySQL was originally the default database server, MariaDB has taken over.. To install it 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..

On Ubuntu 16.04 LTS

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

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

mariadb welcome

Step 3: Install PHP 7.2 FPM 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

Run the commands below to install PHP 7.2 FPM and related modules.

sudo apt install php7.2-fpm 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 install PHP 7.2, run the commands below to open PHP-FPM default file.

sudo nano /etc/php/7.2/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

After making the change above, save the file and close out.

Step 4: Configure Nginx PHP-FPM Settings

Next, open the Nginx site configuration file… by default it’s stored at /etc/nginx/sites-available/default

If you have a custom file, then edit it to enable Nginx PHP support. Run the commands below to open Nginx default site configuration file

sudo nano /etc/nginx/sites-available/default

Then uncomment or remove the # symbol on the highlighted lines below to enable Nginx PHP support.

server {
    listen 80;
    listen [::]:80;
    root /var/www/html;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

    location / {
        try_files $uri $uri/ =404;       
    }

  
     # pass PHP scripts to FastCGI server
        #
        location ~ \.php$ {
               include snippets/fastcgi-php.conf;
        #
        #       # With php-fpm (or other unix sockets):
               fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        #       # With php-cgi (or other tcp sockets):
        #       fastcgi_pass 127.0.0.1:9000;
        }
}

Restart Nginx and PHP-FPM services

sudo systemctl restart nginx.service
sudo systemctl restart php7.2-fpm.service

To test PHP-FPM settings with Nginx, create a phpinfo.php file in Nginx 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

http://localhost/phpinfo.php

You should see PHP default test page…

PHP 7.2 ubuntu nginx

  1. hey
    sudo systemctl restart nginx.service
    sudo systemctl restart php7.2-fpm.service

    phpinfo.php file gives 502 error after executing these commands.

  2. phpinfo 502 error is due to your nginx caonfig looking for an older version of php, you need to edit fastcgi_pass unix:/run/php/php7.0-fpm.sock; to fastcgi_pass unix:/run/php/php7.2-fpm.sock;

    it is in the instructions, but easy to miss, i know i missed it, but figured it out after some googling.

  3. After your:
    sudo apt-get install software-properties-common
    sudo add-apt-repository ppa:ondrej/php
    then
    sudo apt-get update
    I try and do the next line to install all the packages, but get the following errors:

    The following packages have unmet dependencies:
    php7.2-fpm : Depends: php7.2-common (= 7.2.9-1+ubuntu18.04.1+deb.sury.org+1) but 7.2.10-0ubuntu0.18.04.1 is to be installed
    php7.2-intl : Depends: php7.2-common (= 7.2.9-1+ubuntu18.04.1+deb.sury.org+1) but 7.2.10-0ubuntu0.18.04.1 is to be installed

    Depends: libzip4 (>= 1.0) but it is not installable
    E: Unable to correct problems, you have held broken packages.

    I am not entirely sure how to correct this. Google has been no help, even for distros for 18.04 LTS (which is what I am using.) Adding the ppa went fine. Also reading the CAVEATS from the ppa (#3) Stated it is advisable to add ppa:ondrej/nginx-mainline
       or ppa:ondrej/nginx.
    I did try adding ppa:ondrej/nginx, but no luck (Mainline is for Nginx 1.15 iI think, and this one is for 1.14, which I have.)

    Anny suggestions?
