It helps speed up your website by caching web pages and reducing the load on your web server. In this guide, we&#8217;ll walk through the installation of Varnish Cache 6 for both Apache and Nginx on CentOS 8. If you&#8217;re using a  or other <a href=\"https:\/\/ie.netcloud24.com\">Windows VPSVirtual Private Server Hosting<\/a>, the process may vary slightly, but this tutorial focuses on CentOS 8.<\/p>\n<h2>Prerequisites<\/h2>\n<p>Before we begin, make sure you have:<\/p>\n<ul>\n<li>A CentOS 8 server with root access.<\/li>\n<li>Apache or Nginx installed and running.<\/li>\n<li>Basic knowledge of the command line.<\/li>\n<\/ul>\n<p>If you&#8217;re using a , similar configurations can be applied on your server. <a href=\"https:\/\/ie.netcloud24.com\">Windows VPSServer VPS<\/a> solutions offer dedicated resources, making it easier to handle caching.<\/p>\n<h2>Step 1: Update Your System<\/h2>\n<p>Start by updating your CentOS 8 system to ensure all packages are up to date:<\/p>\n<pre><code>sudo dnf update -y<\/code><\/pre>\n<h2>Step 2: Install Apache\/Nginx<\/h2>\n<p>If you don&#8217;t already have Apache or Nginx installed, you can install one of them using the following commands:<\/p>\n<h3>For Apache:<\/h3>\n<pre><code>sudo dnf install httpd -y\r\nsudo systemctl start httpd\r\nsudo systemctl enable httpd<\/code><\/pre>\n<h3>For Nginx:<\/h3>\n<pre><code>sudo dnf install nginx -y\r\nsudo systemctl start nginx\r\nsudo systemctl enable nginx<\/code><\/pre>\n<h2>Step 3: Install Varnish Cache<\/h2>\n<p>To install Varnish Cache 6, we need to add the official Varnish repository to CentOS 8:<\/p>\n<pre><code>sudo dnf install epel-release -y\r\nsudo dnf install https:\/\/packagecloud.io\/varnishcache\/6.0\/packages\/el\/8\/varnish-6.0.7-1.el8.x86_64.rpm<\/code><\/pre>\n<p>Once installed, start and enable the Varnish service:<\/p>\n<pre><code>sudo systemctl start varnish\r\nsudo systemctl enable varnish<\/code><\/pre>\n<h2>Step 4: Configure Varnish for Apache\/Nginx<\/h2>\n<p>By default, Varnish listens on port 6081, but we need to configure it to listen on port 80 and forward traffic to Apache or Nginx on port 8080.<\/p>\n<h3>For Apache:<\/h3>\n<p>Edit the Apache configuration file to change the listening port from 80 to 8080:<\/p>\n<pre><code>sudo nano \/etc\/httpd\/conf\/httpd.conf<\/code><\/pre>\n<p>Find the line <code>Listen 80<\/code> and change it to:<\/p>\n<pre><code>Listen 8080<\/code><\/pre>\n<p>Then, restart Apache:<\/p>\n<pre><code>sudo systemctl restart httpd<\/code><\/pre>\n<h3>For Nginx:<\/h3>\n<p>Modify the Nginx configuration file to listen on port 8080:<\/p>\n<pre><code>sudo nano \/etc\/nginx\/nginx.conf<\/code><\/pre>\n<p>Change the listening port:<\/p>\n<pre><code>listen 8080;<\/code><\/pre>\n<p>Restart Nginx:<\/p>\n<pre><code>sudo systemctl restart nginx<\/code><\/pre>\n<h2>Step 5: Configure Varnish to Listen on Port 80<\/h2>\n<p>Now we need to configure Varnish to listen on port 80. Edit the Varnish systemd service file:<\/p>\n<pre><code>sudo nano \/usr\/lib\/systemd\/system\/varnish.service<\/code><\/pre>\n<p>Find the line starting with <code>ExecStart<\/code> and modify it as follows:<\/p>\n<pre><code>ExecStart=\/usr\/sbin\/varnishd -a :80 -T localhost:6082 -f \/etc\/varnish\/default.vcl -s malloc,256m<\/code><\/pre>\n<p>Reload the systemd daemon and restart Varnish:<\/p>\n<pre><code>sudo systemctl daemon-reload\r\nsudo systemctl restart varnish<\/code><\/pre>\n<h2>Step 6: Test Varnish<\/h2>\n<p>To verify that Varnish is working correctly, you can use <code>curl<\/code> to check if the headers are coming from Varnish:<\/p>\n<pre><code>curl -I http:\/\/yourdomain.com<\/code><\/pre>\n<p>You should see a response header like this:<\/p>\n<pre><code>X-Varnish: 1000<\/code><\/pre>\n<h2>Benefits of VPS Hosting for Varnish<\/h2>\n<p>Using <a href=\"https:\/\/ie.netcloud24.com\">Windows VPSVirtual Private Servers<\/a> for hosting Varnish Cache provides dedicated resources for caching and improving website performance.
