Cerb is an open-source application for web-based collaboration and automation. Cerb can also be used for sending a high volume of emails. Cerb is written in PHP and uses MySQL/MariaDB to store its data. In this tutorial, you will learn how to install Cerb on CentOS 7.
- An ITWeb.Services CentOS 7 server instance.
- A sudo user.
Step 1: System update
Before installing any packages on a CentOS server instance, it is recommended to update the system. Login using the sudo user and run the following commands to update the system.
sudo yum -y install epel-release sudo yum -y update sudo shutdown -r now
Once the system has finished rebooting, log in again as the sudo user and proceed to the next step.
Step 2: Install Apache web server
Run the following command to install the Apache web server.
sudo yum -y install httpd
Once Apache is installed, run the following command to start Apache and enable it to automatically start at boot time.
sudo systemctl start httpd.service sudo systemctl enable httpd.service
Step 3: Install PHP 7
Cerb is compatible with any version of PHP greater than 5.5. You can use the latest version of PHP 7 in order to get maximum performance. Add and enable the Remi repository on your system.
sudo rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm sudo yum -y install yum-utils sudo yum-config-manager --enable remi-php71
Install the latest version of PHP with Cerb’s required modules.
sudo yum -y install php php-curl php-dom php-gd php-imap php-json php-mbstring php-mysqli php-openssl php-pcre php-session php-simplexml php-xml php-spl php-mailparse
/etc/php.ini using your favorite editor.
sudo nano /etc/php.ini
Update the following lines.
memory_limit = 128M # 128M or Higher according to the memory available upload_max_filesize = 2M # 32M or Higher post_max_size = 8M # 32M or Higher ;upload_tmp_dir = # Uncomment and change it to upload_tmp_dir = /tmp
Save the file and exit from the text editor. Then, restart Apache.
sudo systemctl restart httpd.service
Step 4: Install MariaDB
Install MariaDB using the following command. MariaDB is a fork of MySQL.
sudo yum -y install mariadb mariadb-server
Once MariaDB has been installed, run the following command to start MariaDB and enable it to automatically start on boot.
sudo systemctl start mariadb.service sudo systemctl enable mariadb.service
Now secure your MariaDB installation using the following command.
You will be asked for the current root password. As we have just installed MariaDB, the root password is not set. Press the “Enter” key to proceed. Set a strong root password for your MySQL server and answer
Y for all of the other questions asked. All the questions asked are self explanatory.
Step 5: Create a database for Cerb
Login to the MySQL shell as the root user using the following command.
mysql -u root -p
Provide the password for root user you just set earlier.
Now run the following queries to create the database and database user for the Cerb installation.
CREATE DATABASE cerb_data; CREATE USER 'cerb_user'@'localhost' IDENTIFIED BY 'StrongPassword'; GRANT ALL PRIVILEGES ON cerb_data.* TO 'cerb_user'@'localhost'; FLUSH PRIVILEGES; EXIT;
Make sure that you use a semicolon at the end of each query above. You can replace the database name
cerb_data and database username
cerb_user according to your needs. Be sure to change
StrongPassword with a very strong password.
Step 6: Install Cerb
git if you do not have it already installed.
sudo yum -y install git
Now, switch to the
webroot directory of Apache and clone the latest version of Cerb using the following command.
cd /var/www/html sudo git clone git://github.com/wgm/cerb.git cerb
Provide appropriate ownership and file permissions using the following commands.
cd /var/www/html/cerb sudo chown -R apache:apache . sudo chmod -R u+w framework.config.php storage
You may also need to allow HTTP traffic on port
80 through the system firewall.
sudo firewall-cmd --zone=public --permanent --add-service=http sudo firewall-cmd --reload
Now complete the installation using a web browser.
Step 7: Finish installation
Go to the following link using your favorite web browser.
192.0.2.1 with the IP address of your server. If you have followed the tutorial correctly, you should have all of the requirements satisfied. On the “Database Setup” interface, choose the driver
MySQLi and engine
InnoDB. Also provide the database name and credentials that you have created earlier. Once the database connection is checked, it will ask to provide details of your SMTP server to send outgoing emails. Finally, create the administrator user.
Cerb is now installed on your server.
Run the following command to delete the
install directory before using it.
sudo rm -rf /var/www/html/cerb/install
You can now use Cerb through your web browser.
