In the steps that follow, we will look at how to install and set up the Drupal content management system on a CentOS v7 virtual server.
A few words about Drupal
Drupal is one of the most well-known content management systems (CMS) in the world. It is free, easy to install, and has a lot of features for making websites. Two hundred new features have been added to the eighth version.
- A lot of languages to choose from for the interface;
- Changes to caching and how it works with CDN;
- Ability to create dynamic content; Ability to control the display without using program code;
- Use for both personal and business needs;
- Adapts to the needs of disabled users.
If you put Drupal in a container, it will be much easier to set up. You won’t have to install Apache or Nginx again, prepare empty databases, or load the PHP web language.
How to set up Docker
Docker is a system for making containers. For it to work with Drupal, it needs to be installed on the server ahead of time.
Step 2 is to download the image for the mariadb database management system. If the device doesn’t have the latest version, it can be downloaded through the following line:
docker pull mariadb
Additionally, you need to download CMS Drupal:
docker pull drupal
The image will contain everything you need: a web scripting language and Apache.
The latest Dockerfile is at the link .
Please note that if you want to load a certain CMS model, you need to write the model name in the line after the colon. For example, drupal:7.5.5.
When loading the database, you need to specify the main parameters:
docker run -e MYSQL_ROOT_PASSWORD=admin -e MYSQL_DATABASE= -e MYSQL_USER= -e MYSQL_PASSWORD= -v mariadb:/var/lib/mysql -d --name mariadb
More detailed example:
docker run -e MYSQL_ROOT_PASSWORD=admin -e MYSQL_DATABASE=drupal -e MYSQL_USER=duser -eMYSQL_PASSWORD=drupalpass -v mariadb:/var/lib/mysql -d --name mariadb mariadb
At the end, the user will get a container with a deployed database full of data inside. With the -v option, a mounted server partition is made into which the database is installed.
Starting Drupal and connecting it to the DBMS with the database hostname is done as follows:
docker run --name --link mariadb: -p : -d drupal
docker run --name drupal8 --link mariadb:mariadb -p 80:80 -d drupal
To be able to work via remote access, you need to open the port:
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
How to set up Drupal
You need to open a browser and follow the link, not forgetting to specify the IP:
In this way:
Language choice is the first step (in this case, it is Russian).
The second one shows the installation profile (standard is selected).
The third is choosing the name, user name, and password for the database.
You can write down the host and use more settings.
As soon as the changes are saved, the Drupal installation will start.
During the process, the system will ask you for personal information, such as your website’s domain name, email address, main user name, and password.
You can use different difficulty levels to write a strong password.
The configuration will then be updated on its own.
After this, a window with the control panel will open. The installation is now done.
To enter the Drupada panel, you will need to re-enter the username and password from the account that was generated earlier.
The whole process of installation is done.
