How to Install SilverStripe on CentOS 7

SilverStripe is a free and open source content management system. It is written in PHP and uses MySQL to store its data. SilverStripe is very flexible, extensible and easy to use application. It is easy to learn and optimized to produce high-quality reusable codes. It is responsive and available in many languages. It is a very secure platform as it is written from ground. It is a popular CMS and used by prominent companies like Lenovo and Forbes etc.

In this tutorial, we will be installing SilverStripe on CentOS 7 server.


SilverStripe does not require any special hardware requirements. It can be installed on servers with a small amount of RAM. All the required dependencies will be installed throughout the tutorial. You will need a minimal installation of CentOS 7 with root access on it. If you are logged in as a non-root user, you can run sudo -i to switch to root user.

Installing SilverStripe

Before installing any package it is recommended that you update the packages and repository using the following command.

yum -y update

Now install Apache, Git, and MariaDB, which is a fork or MySQL using the following command.

yum -y install httpd mariadb-server mariadb git

SilverStripe requires PHP 5.3.3 or higher. In this tutorial, we will install PHP 5.6. Install EPEL repository using following commands.

yum -y install epel-release yum -y update

Now install Webtatic repository using the following commands.

rpm -Uvh yum -y update

To install PHP 5.6 and all the required PHP modules, run the following command.

yum -y install php56w php56w-openssl php56w-dom php56w-mysqli php56w-cli php56w-mbstring php56w-gd php56w-fileinfo php56w-hash php56w-iconv php56w-simplexml php56w-session php56w-tokenizer php56w-xml php56w-tidy

Once you have PHP installed, you can check the version of PHP using the following command.

php -v

You should get output similar to this.

[root@liptan-pc ~]# php -v
PHP 5.6.30 (cli) (built: Jan 19 2017 22:31:39)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

You will need to edit the php.ini file to configure the timezone. Run the following command to open the file in nano editor.

nano /etc/php.ini

Now find the following line.

;date.timezone =

Uncomment the line and provide the timezone for your application. An example may be.

date.timezone = Asia/Kolkata

Now start Apache web server and enable it to start at boot time using the following command.

systemctl start httpd systemctl enable httpd

To start MariaDB and enable it to start at boot time using the following commands.

systemctl start mariadb systemctl enable mariadb

Now run the following commands to secure your MySQL or MariaDB installation.


It will run a small script which asks you to provide the root password for MariaDB. As we have just installed MariaDB, the root password is not set, just press enter to proceed further. Set a root password for MySQL root user and answer y for all other questions asked.

Now you will need to create a database to store SilverStripe data.

To create a database we will need to login to MySQL command line first. Run the following command for same.

mysql -u root -p

This will prompt you for the password, provide the root password of MySQL which you have set earlier. Now run the following query to create a new database for your SilverStripe installation.


To create a new database user, run the following query.

CREATE USER 'ss_user'@'localhost' IDENTIFIED BY 'StrongPassword';

Replace StrongPassword with a strong password. Now provide the appropriate privileges to your database user over the database you have created. Run the following command.

GRANT ALL PRIVILEGES ON ss_data.* TO 'ss_user'@'localhost';

Now run the following command to immediately apply the changes on the database privileges.


Exit from MySQL prompt using exit command.

SilverStripe can be installed in two ways, either using composer or using the setup archive. In this tutorial both the methods are explained.

Using Composer

If you want to use Composer to install SilverStripe, you will need to install Composer. Composer is a dependency manager for PHP.

curl -sS | php mv composer.phar /usr/bin/composer

Now switch to the webroot directory of Apache web server and download SilverStripe using following command.

cd /var/www composer create-project silverstripe/installer silverstripe

Once the download finishes, go to the newly created SilverStripe directory and install the required Composer dependencies using the following commands.

cd silverstripe composer install

SilverStripe files are now downloaded, you can now continue the tutorial from disabling SELinux.

Using Setup Archive

To install SilverStripe using the setup archive, run the following command to download the archive.

cd /var/www wget -O

You can always check the SilverStripe download page to look for the link to the latest version of the archive.

Now extract the archive using the following command.

unzip -d silverstripe

If you do not have unzip installed, you can run yum -y install unzip.

Now you will need to disable your SELinux. To temporary disable SELinux, run the following command.

setenforce 0

To completely disable the SELinux you will need to edit /etc/selinux/config file.

nano /etc/selinux/config

Find the following line:


Change it to:


Now, you will need to provide the ownership of the application to web server user using the following command.

chown -R apache:apache /var/www/silverstripe

You may also need to allow HTTP traffic on port 80 through the firewall if you are running one. Run the following commands for same.

firewall-cmd --zone=public --permanent --add-service=http firewall-cmd --reload

Now create a virtual host for the SilverStripe application. Run the following command for same.

nano /etc/httpd/conf.d/

Paste the following lines into the file.

<VirtualHost *:80>
    DocumentRoot "/var/www/silverstripe"
    <Directory "/var/www/silverstripe">
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    ErrorLog "/var/log/httpd/"
    CustomLog "/var/log/httpd/" combined

Replace with any domain or subdomain you want to use to access the application. Save the file and exit from the editor. Run the following command to restart your Apache server.

systemctl restart httpd

Now complete the installation using a web browser, go to the following link using your favorite web browser.
