Drupal is an open source, flexible, highly scalable and secure Content Management System ( CMS) which allows users to easily build and create web sites. It can be extended using modules and enables users to transform content management into powerful digital solutions.Drupal runs on a web server like Apache, IIS, Lighttpd, Cherokee, Nginx and a backend databases MySQL, MongoDB, MariaDB, PostgreSQL, SQLite, MS SQL Server.In this article, we will show how to perform a manual installation and configuration of Drupal 8 on RHEL 7/6, CentOS 7/6 and Fedora 20-25 distributions using LAMP setup. Drupal Requirement:. Apache 2.x (Recommended). PHP 5.5.9 or higher (5.5 recommended). MySQL 5.5.3 or MariaDB 5.5.20 with PHP Data Objects (PDO)For this setup, I am using website hostname as “ drupal.tecmint.com” and IP address is “ 192.168.0.104“.
These settings may differ at your environment, so please make changes as appropriate. Step 1: Installing Apache Web Server1. First we will start with installing Apache web server from the official repositories: # yum install httpd2.
After the installation completes, the service will be disabled at first, so we need to start it manually for the mean time and enable it to start automatically from the next system boot as well: - On SystemD - CentOS/RHEL 7 and Fedora 22+ -# systemctl start httpd# systemctl enable httpd- On SysVInit - CentOS/RHEL 6 and Fedora -# service httpd start# chkconfig -level 35 httpd on3. Next, in order to allow access to Apache services from HTTP and HTTPS, we have to open 80 and 443 port where the HTTPD daemon is listening as follows: - On FirewallD - CentOS/RHEL 7 and Fedora 22+ -# firewall-cmd -permanent -zone=public -add-service=http# firewall-cmd -permanent -zone=public -add-service=https# firewall-cmd -reload- On IPtables - CentOS/RHEL 6 and Fedora 22+ -# iptables -A INPUT -p tcp -m tcp -dport 80 -j ACCEPT# iptables -A INPUT -p tcp -m tcp -dport 443 -j ACCEPT# service iptables save# service iptables restart4. Now verify that Apache is working fine, open a remote browser and type your server IP Address using HTTP protocol in the URL:and the default Apache2 page should appear as in the screenshot below. Apache Default Page Step 2: Install PHP Support for Apache5. Next, install PHP and the required PHP modules.
# yum install php php-mbstring php-gd php-xml php-pear php-fpm php-mysql php-pdo php-opcacheImportant: If you want to install PHP 7.0, you need to add the following repositories: EPEL and Webtactic in order to install PHP 7.0 using yum: - Install PHP 7 in CentOS/RHEL and Fedora -# rpm -Uvh rpm -Uvh yum install php70w php70w-opcache php70w-mbstring php70w-gd php70w-xml php70w-pear php70w-fpm php70w-mysql php70w-pdo6. Next, to get a full information about the PHP installation and all its current configurations from a web browser, let’s create a info.php file in the Apache DocumentRoot ( /var/www/html) using the following command. # echo ' /var/www/html/info.phpthen restart HTTPD service and enter the URL in the web browser.
# systemctl restart httpdOR# service httpd restart. Verify PHP Information Step 3: Install and Configure MariaDB Database7. For your information, Red Hat Enterprise Linux/CentOS 7.0 moved from supporting MySQL to MariaDB as the default database management system.To install MariaDB database, you need to add the following to file /etc/yum.repos.d/MariaDB.repo as shown.
mariadbname = MariaDBbaseurl = the repo file in place you can able to install MariaDB like so: # yum install mariadb-server mariadb8. When the installation of MariaDB packages completes, start the database daemon for the mean time and enable it to start automatically at the next boot.
On SystemD - CentOS/RHEL 7 and Fedora 22+ -# systemctl start mariadb# systemctl enable mariadb- On SysVInit - CentOS/RHEL 6 and Fedora -# service mysqld start# chkconfig -level 35 mysqld on9. Then run the mysqlsecureinstallation script to secure the database (set root password, disable remote root login, remove test database and remove anonymous users) as follows: # mysqlsecureinstallation. Mysql Secure Installation Step 4: Install and Configure Drupal 8 in CentOS10. Here, we will start by (i.e 8.2.6) using the.
If you don’t have wget and gzip packages installed, then use the following command to install them: # yum install wget gzip# wget -c Afterwards, let’s and move the Drupal folder into the Apache Document Root ( /var/www/html). # tar -zxvf drupal-8.2.6.tar.gz# mv drupal-8.2.6 /var/www/html/drupal12. Then, create the settings file settings.php, from the sample settings file default.settings.php) in the folder ( /var/www/html/drupal/sites/default) and then set the appropriate permissions on the Drupal site directory, including sub-directories and files as follows: # cd /var/www/html/drupal/sites/default/# cp default.settings.php settings.php# chown -R apache:apache /var/www/html/drupal/13. Importantly, set the SELinux rule on the folder “ /var/www/html/drupal/sites/” as below: # chcon -R -t httpdsyscontentrwt /var/www/html/drupal/sites/14. Now we have to create a database and a user for the Drupal site to manage. # mysql -u root -pEnter password. MySQL Shell Welcome to the MariaDB monitor.

This is simply not possible under regular CentOS7 without deviating from the instructions and also breaking the chain of enterprise updates.I know of Remi’s fine work. I’m not asking about that. I’m mentioning that, in case it’s not clear, the instructions give a different result than anticipated. I don’t mean to belabour so much as to firmly state as clearly as I can that the instructions have a flaw in that following them exactly gives a result not predicted by the instructions.In short, the instructions are broken.We can talk about the added risks of breaking enterprise updates on a very vulnerable package, but that’s a little more ‘next level’ than the bits I worry you may have already overlooked; so we’ll save that.
