[CentOS]: How To Install Linux-dash Web Based Monitoring System In CentOS/RHEL

How To Install Linux-dash Web Based Monitoring System In CentOS/RHEL

Linux-dash is a web-based lightweight monitoring dashboard for Linux machines. This application will display real-time, various system properties, such as CPU load, RAM usage, disk usage, Internet speed, network connections, RX/TX bandwidth, logged-in users, running processes etc. It will not store long term statistics, Thus it doesn’t have a backend database.

In this article i will show you how to install and setup Linux dash, Here my web server is Nginx.

Installation

First of all we should enable, EPEL repository.

Next, we need to install nginx with the following command.

sudo yum install nginx

Install php-fpm component

sudo yum install git php-common php-fpm

Now, we have to configure nginx for Linux-dash. So create /etc/nginx/conf.d/linuxdash.conf as follows.

sudo vim /etc/nginx/conf.d/linuxdash.conf

server {
 server_name $domain_name;
 listen 8080;
 root /var/www;
 index index.html index.php;
 access_log /var/log/nginx/access.log;
 error_log /var/log/nginx/error.log;
 
 location ~* \.(?:xml|ogg|mp3|mp4|ogv|svg|svgz|eot|otf|woff|ttf|css|js|jpg|jpeg|gif|png|ico)$ {
 try_files $uri =404;
 expires max;
 access_log off;
 add_header Pragma public;
 add_header Cache-Control "public, must-revalidate, proxy-revalidate";
 }
 
 location /linux-dash {
 index index.html index.php;
 }
 
 # PHP-FPM via sockets
 location ~ \.php(/|$) {
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 fastcgi_split_path_info ^(.+?\.php)(/.*)$;
 fastcgi_pass unix:/var/run/php-fpm.sock;
 if (!-f $document_root$fastcgi_script_name) {
 return 404;
 }
 try_files $uri $uri/ /index.php?$args;
 include fastcgi_params;
 }
}

Next job is to configure php-fpm. Open  /etc/php-fpm.d/www.conf in your Favorite editor.

sudo vim /etc/php-fpm.d/www.conf

Make sure to set “listen”, “user” and “group” fields as below. You can leave the rest of the configuration unchanged.

. . .
listen = /var/run/php-fpm.sock
user = nginx
group = nginx
. . .

Now, We are going to Download and install linux-dash under /var/www

git clone https://github.com/afaqurk/linux-dash.git
sudo cp -r linux-dash/ /var/www/
sudo chown -R nginx:nginx /var/www

Next, restart Nginx web server as well as php-fpm

sudo service nginx restart
sudo service php-fpm restart

Set nginx and php-fpm to auto-start upon boot

sudo chkconfig nginx on
sudo chkconfig php-fpm on

In this example, we have configured linux-dash to use TCP port 8080. So make sure that the firewall is not blocking TCP port 8080.

Monitor a Linux server with linux-dash

You can access Linux-dash by pointing you browser to http://<linux-IP-address>:8080/linux-dash/

The web dashboard consists of several widgets, each of which displays particular system properties. You can customize the look of the web dashboard by rearranging and/or closing some of the widgets.

Good day!
