1. What is linux - dash?#

linux - dash is an open - source, lightweight web - based dashboard for monitoring Linux server performance. It provides a user - friendly interface that displays essential system statistics and allows you to manage your server remotely from any device with a web browser. Built using PHP on the back - end and Bootstrap, HTML, CSS, and JavaScript on the front - end, linux - dash is easy to install and doesn't require any complex database configurations. It can be run on various Linux distributions, including Ubuntu, CentOS, Debian, and Fedora.

2. Prerequisites for Installation#

Before you start installing linux - dash, make sure your server meets the following requirements:

  • A Linux server running a supported distribution (e.g., Ubuntu 18.04+, CentOS 7+, Debian 9+).
  • A web server installed on the server. Popular choices include Apache or Nginx. For this guide, we'll assume you have Nginx installed.
  • Basic knowledge of the Linux command line.

3. Installation Steps#

Step 1: Install Required Dependencies#

linux - dash is a PHP application that requires PHP and Composer. On Ubuntu and Debian systems, install the required packages:

sudo apt update
sudo apt install nginx php php-fpm php-curl php-json composer

On CentOS and Fedora systems:

sudo yum install nginx php php-fpm php-curl php-json
sudo systemctl start nginx
sudo systemctl enable nginx

Note: On CentOS, you may need to use php composer.phar instead of the composer command after downloading Composer, or install it via yum install composer if available.

Step 2: Clone the linux - dash Repository#

First, navigate to the directory where you want to store linux - dash. A common location is /var/www/html.

cd /var/www/html
sudo git clone https://github.com/afaqurk/linux-dash.git

Step 3: Install PHP Dependencies#

Navigate to the linux - dash directory and install the required Composer dependencies:

cd /var/www/html/linux-dash
sudo composer install --no-dev

Step 4: Configure Nginx#

Create a new Nginx configuration file for linux - dash.

sudo nano /etc/nginx/sites-available/linux-dash

Add the following configuration to properly handle PHP requests:

server {
    listen 80;
    server_name your_server_ip_or_domain;
 
    root /var/www/html/linux-dash;
    index index.php;
 
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }
 
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php-fpm.sock; # Adjust path based on your PHP-FPM version (e.g., php7.4-fpm.sock, php8.0-fpm.sock)
    }
}

Replace your_server_ip_or_domain with your actual server IP address or domain name. Ensure the fastcgi_pass path matches your PHP-FPM socket location.

Create a symbolic link to enable the configuration:

sudo ln -s /etc/nginx/sites-available/linux-dash /etc/nginx/sites-enabled/

Test the Nginx configuration and restart Nginx:

sudo nginx -t
sudo systemctl restart nginx

Step 5: Adjust Permissions#

Make sure the web server has the necessary permissions to access the linux - dash files.

sudo chown -R www-data:www-data /var/www/html/linux-dash
sudo chmod -R 755 /var/www/html/linux-dash

4. Features of linux - dash#

  • System Overview: Displays a summary of the server's uptime, load average, and the number of running processes.
  • CPU Usage: Shows real - time CPU usage percentage, along with a breakdown of user, system, and idle time.
  • Memory Usage: Provides information about total, used, and free memory, as well as swap space usage.
  • Disk I/O: Monitors disk read and write operations, including the number of I/O requests and the amount of data transferred.
  • Network Traffic: Displays incoming and outgoing network traffic, allowing you to identify network bottlenecks.
  • Process List: Lists all running processes, including their CPU and memory usage, process ID, and command name.

5. Using linux - dash to Monitor Server Performance#

Once you have successfully installed linux - dash, you can access the dashboard by opening your web browser and navigating to http://your_server_ip_or_domain.

  • Navigation: The dashboard has a simple and intuitive layout. You can easily switch between different sections using the menu on the left - hand side.
  • Real - Time Monitoring: All the statistics on the dashboard are updated in real - time, allowing you to track changes in server performance as they occur.
  • Process Management: You can view detailed information about running processes and even terminate processes if necessary.

6. Troubleshooting Common Issues#

  • Permission Errors: If you encounter permission issues while accessing the dashboard, make sure the web server user has the correct permissions to access the linux - dash directory.
  • Nginx Configuration Errors: If the dashboard is not loading, check your Nginx configuration file for syntax errors. You can use the sudo nginx -t command to test the configuration.
  • Network Connectivity Issues: Ensure that your server's firewall allows incoming traffic on port 80 (or the port you have configured Nginx to listen on).

7. Conclusion#

linux - dash is a powerful and user - friendly tool for monitoring Linux server performance remotely. Its simple installation process, rich set of features, and real - time monitoring capabilities make it an ideal choice for both beginners and experienced system administrators. By using linux - dash, you can keep a close eye on your server's health and performance, and take proactive measures to ensure its smooth operation.
