Concrete5 also requires a database server and MariaDB is a great place to start when looking for an open-source database server.

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 the 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 the MariaDB server.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

  • Remove test database and access to it? [Y/n]:  Y
  • Reload privilege tables now? [Y/n]:  Y

Install PHP-FPM and Related Modules

PHP 7.1 isn’t available on Ubuntu’s default repositories. 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 installing PHP, run the commands below to open the Nginx PHP default file.

sudo nano /etc/php/7.1/cli/php.ini

Then make the change to the following lines below in the file and save.

memory_limit = 256M
upload_max_filesize = 64M
max_execution_time = 240
max_input_vars = 1500
cgi.fix_pathinfo = 0

Create Concrete5 Database

Now that you’ve installed all the packages that are required, continue below to start configuring the servers.

First, run the commands below to create the Concrete5 database.

Run the commands below to log on 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 concrete5

CREATE DATABASE concrete5;

Create a database user called concrete5user with a new password

CREATE USER 'concrete5user'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the database.

GRANT ALL ON concrete5.* TO 'concrete5user'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Download Concrete5 Latest Release

Next, visit the Concrete5 site and download the latest version. After downloading, run the commands below to extract the download file into the Nginx root directory.

cd /tmp && wget --trust-server-names http://www.concrete5.org/download_file/-/view/96959/ -O concrete5.zip
unzip concrete5.zip
sudo mv concrete5-8.2.1 /var/www/html/concrete5

Then run the commands below to set the correct permissions for Concrete5 to function.

sudo chown -R www-data:www-data /var/www/html/concrete5/
sudo chmod -R 755 /var/www/html/concrete5/

Configure Nginx Site

Finally, configure the Nginx server block configuration file for Concrete5. This file will control how users access Concrete5 content.

Run the commands below to create a new configuration file called concrete5

sudo nano /etc/nginx/sites-available/concrete5

Then copy and paste the content below into the file and save it. Replace the highlighted line with your domain name and root location.

server {
    listen 80;
    listen [::]:80;
    root /var/www/html/concrete5;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

    location / {
    try_files $uri $uri/ /index.php$request_uri /index.php;        
    }

    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;
        include fastcgi_params;
    }

}

Save the file and exit.

Enable Concrete5 server block

After configuring the server block above, enable it by running the commands below

sudo ln -s /etc/nginx/sites-available/concrete5 /etc/nginx/sites-enabled/

To load all the settings above, restart Apache2 by running the commands below.
