Live helper chat is a free, flexible, and open-source live support chat for your website. It is written in PHP and uses MySQL/MariaDB to store its data. It provides lots of features such as online user tracking, multiple chats, archive chat, user screenshots, file upload and much more.

First you will need to update your OS with the latest release and update its installed packages and repositories using below command:
sudo yum update -y

We need to install a LAMP stack.
You can install it by running the following command:
sudo yum install php httpd mariadb mariadb-server php-cli php-mysqli php-mysqlnd php-gd php-bcmath php-pdo php-mbstring -y
Once all the packages are installed, start the Apache and MariaDB services then enable it to start on boot with the following command:
sudo systemctl start httpd sudo systemctl start mariadb sudo systemctl enable httpd sudo systemctl enable mariadb
Configure MariaDB Database
By default MariaDB installation is not secured, so you will need to secure it first.
To do so, run the following script:
Answer all the questions as shown below and provide a strong password:
Enter current password for root (enter for none): Enter Set root password? [Y/n]: Y Remove anonymous users? [Y/n]: Y Disallow root login remotely? [Y/n]: Y Remove test database and access to it? [Y/n]: Y Reload privilege tables now? [Y/n]: Y
Log in to MariaDB shell with the following command:
mysql -u root -p
Enter the root password when asked, then create a database for Live Helper Chat:
MariaDB [(none)]>CREATE DATABASE livechatdb;
Create a database user and password for Live Helper Chat:
MariaDB [(none)]>CREATE USER 'user'@'localhost' IDENTIFIED BY 'password'; MariaDB [(none)]>GRANT ALL PRIVILEGES ON livechatdb.* TO 'user'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION; MariaDB [(none)]>FLUSH PRIVILEGES; MariaDB [(none)]>exit;

You can download the latest version of Live Helper Chat from the GitHub repository with the following command:
Once the download is complete, extract the downloaded archive with the following command:
Move the extracted directory to the Apache web root directory:
sudo mv livehelperchat-master /var/www/html/livechat
Give proper permissions to the
sudo chown -R apache:apache /var/www/html/livechat
Configure Apache for Live Helper Chat
Now we will need to configure an Apache virtual host for Live Helper Chat.
You can do this by creating
sudo nano /etc/httpd/conf.d/livechat
Add the following line:
<VirtualHost *:80> ServerAdmin firstname.lastname@example.org DocumentRoot "/var/www/html/livechat/lhc_web" ServerName example.com ErrorLog "/var/log/httpd/livechat-error_log" CustomLog "/var/log/httpd/livechat-access_log" combined </VirtualHost>
Save and close the file when you are finished.
You will also need to enable
mod_rewrite in Apache. You can do this by editing the
sudo nano /etc/httpd/conf/httpd.conf
Change the following line:
<Directory "/var/www/html"> AllowOverride All
Save the file and restart Apache service:
sudo systemctl restart httpd
Next we will need to allow HTTP on port
80 through the local firewall,
firewalld. You can do this by running the following command:
sudo firewall-cmd --zone=public --add-service=http --permanent sudo firewall-cmd --reload
