Step 1 - Install Required Packages

Before starting the installation process, make sure you have installed the required packages.

Step 2 - Download KChat

To download KChat, use the following command:

Now, extract the downloaded zip file using:

unzip master.zip

Step 3 - Install KChat

Once you have extracted the KChat files, navigate to the extracted directory using:

cd kchat-master

Create a new database and user for KChat using:

mysql -u root -p

CREATE DATABASE kchat_db;
CREATE USER 'kchat_user'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON kchat_db.* TO 'kchat_user'@'localhost';
FLUSH PRIVILEGES;
exit

Now, rename the config.php.sample file to config.php:

cp config.php.sample config.php

Edit the config.php file and set the database details:

nano config.php

Update the following lines:

define('DB_HOST', 'localhost');
define('DB_USER', 'kchat_user');
define('DB_PASSWORD', 'password');
define('DB_DATABASE', 'kchat_db');

Save and close the file.

Copy the KChat files to the Nginx web root directory /usr/share/nginx/html/kchat:

sudo cp -r . /usr/share/nginx/html/kchat

Configure the Nginx server to serve KChat by creating a kchat.conf file:

sudo nano /etc/nginx/conf.d/kchat.conf

And add the following content:

server {
    listen 80;
    listen [::]:80;
    root /usr/share/nginx/html/kchat;
    index index.php index.html index.htm;
    server_name localhost;
    location / {
            try_files $uri $uri/ /index.php$is_args$args;
    }
    location ~ \.php$ {
            fastcgi_pass unix:/var/run/php-fpm/www.sock;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param SCRIPT_NAME $fastcgi_script_name;
            include fastcgi_params;
    }
}

Save and close the file.
