How to Install Osclass on a CentOS 7

Install Osclass on a CentOS
Osclass is your one-stop shop to building your own classifieds marketplace. Create a site with real estate ads, job listings, car classifieds, rentals, or just about anything you can imagine. With dozens of templates, themes and plugins, Osclass is fully customizable.

INSTALLATION
Install Apache web server

yum -y install httpd

Once the installation of the Apache web server is completed, start it and make it to start automatically on boot.

systemctl start httpd
systemctl enable httpd

Osclass is written in the PHP programming language, so we need to install PHP and a few PHP extensions

yum -y install php php-mysql

Run the following command on your terminal to install MariaDB server on your CentOS 7 server

yum -y install mariadb mariadb-server

Once the installation of the database server is completed start the MariaDB server and set it to start on system boot

systemctl start mariadb
systemctl enable mariadb

Then, run the mysql_secure_installation script. This script will help you improve the security of your MariaDB installation and set your MariaDB root password.

Osclass requires an empty database, so login to the MariaDB server with the root user and create a new user and database that will be used by Osclass to store information

mysql -u root -p

CREATE DATABASE osclass;
CREATE USER 'osclassuser'@'localhost' IDENTIFIED BY 'PASSWORD';
GRANT ALL PRIVILEGES ON `osclass`.* TO 'osclassuser'@'localhost';
FLUSH PRIVILEGES;
exit

Go to the official Osclass website and download the latest release of their application then follow the bellow instruction:

wget https://static.osclass.org/download/osclass.3.6.1.zip
mkdir /var/www/html/osclass
unzip osclass.3.6.1.zip -d /var/www/html/osclass

Set the Apache user to be owner of the Osclass files and directories

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

On the next step we will create Apache virtual host for your Osclass based website. Create a '/etc/httpd/conf.d/vhosts.conf' file with the following content:

IncludeOptional vhosts.d/*.conf

Create a 'vhosts.d/' directory:

mkdir /etc/httpd/vhosts.d/

Create the virtual host with the following content:

vim /etc/httpd/vhosts.d/yourdomain.com.conf

<VirtualHost YOUR_SERVER_IP:80>
ServerAdmin webmaster@yourdomain.com
DocumentRoot "/var/www/html/osclass/"
ServerName yourdomain.com
ServerAlias www.yourdomain.com
ErrorLog "/var/log/httpd/yourdomain.com-error_log"
CustomLog "/var/log/httpd/yourdomain.com-access_log" combined

<Directory "/var/www/html/osclass/">
DirectoryIndex index.html index.php
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>

Save the changes and restart the Apache web server for the changes to take effect.

systemctl restart httpd
