Drupal is an open-source content management framework written in PHP, which consists of a content management system and a PHP development framework. It can be used to build rich-featured dynamic websites ranging from personal blogs to large communities.
This tutorial describes how to build a Drupal ecommerce website on a CVM instance.
Software environments used here include CentOS v7.2, Drupal v7.56, and PHP v5.4.16.

Logging in to the CVM Instance

For more information on how to purchase and access CVM instances, see Getting Started with Linux-based CVM.

Installing the MariaDB Service

1. MariaDB is supported by CentOS v7 and higher by default, so it is used here. Install the MariaDB service in the CVM instance with yum.

   yum install mariadb-server mariadb -y

2. Start the MariaDB service.

   systemctl start mariadb

3. Create a database named drupal for Drupal.

   mysqladmin -u root -p create drupal

   Here, "drupal" is the database name used in the Drupal service.
4. Create a user for the database.

   mysql -u root -p

   Authorize the user and exit the database after the authorization is successful.

   GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON drupal.* TO 'username'@'localhost' IDENTIFIED BY 'password';
   FLUSH PRIVILEGES;
   exit

   Here, "username" and "password" are the database username and password used in the Drupal service, respectively.

Installing the Apache Service

1. Install Apache in the CVM instance with yum.

   yum install httpd -y

2. Start the Apache service.

   service httpd start

3. Test Apache.

   In this step, you should configure an inbound rule with the source being all and the port protocol being TCP:80 in the security group of your CVM instance. For more information on how to configure the security group, see Security Group.

   Enter http://115.xxx.xxx.xxx/ in your local browser (where 115.xxx.xxx.xxx is the public IP of your CVM instance). If the following page appears, Apahce has started successfully.
   

Installing PHP

1. Install PHP and its extensions in the CVM instance with yum.

   yum install php php-dom php-dg php-mysql php-pdo -y

2. Create an info.php file in the /var/www/html directory of the CVM instance to check whether PHP is successfully installed. Below is the sample code:

   <?php phpinfo(); ?>

3. Restart the Apache service.

   service httpd restart

4. Enter http://115.xxx.xxx.xxx/info.php in your local browser (where 115.xxx.xxx.xxx is the public IP of your CVM instance). If the following page appears, PHP has been installed successfully.
   

Installing the Drupal Service

1. Download the Drupal installation package.

   wget http://ftp.drupal.org/files/projects/drupal-7.56.zip

2. Decompress the package to the root directory of the website.

   unzip drupal-7.56.zip 
   mv drupal-7.56/* /var/www/html/

3. Download the translation kit.

   cd /var/www/html/
   wget -P profiles/standard/translations http://ftp.drupal.org/files/translations/7.x/drupal/drupal-7.56.zh-hans.po

4. Modify the owner and group to which the sites directory belongs.

chown -R apache:apache /var/www/html/sites

5. Restart the Apache service.

service httpd restart

6. Enter http://115.xxx.xxx.xxx/ in your local browser (where 115.xxx.xxx.xxx is the public IP of your CVM instance) to go to the installation interface of Drupal, select the version to be installed, and click Save and continue.
   

7. Select the language for installation and click Save and continue.

8. Set up the database and enter the database information you configured when installing the MariaDB service.

9. Enter the site information.

10. Complete the process of Drupal installation.

11. You can access http://115.xxx.xxx.xxx/ (115.xxx.xxx.xxx is the public IP of your CVM) to customize the website.
