In this article, we are gonna explain on how to setup varnish to listen on port 80(http)\u00a0<\/em>and forward request to backend webserver(our example, we deals with nginx as backend server). The backend server can be anything, either Apache or Nginx webserver.<\/p>\n

Assumption:<\/h5>\n
    \n
  1. Apache or nginx webserver. This post also deals with how to change the webserver port 80 on webserver.<\/li>\n
  2. Ubuntu 16<\/li>\n<\/ol>\n

    Incase, if there is no webserver installed, refer the following post on installing webserver.<\/p>\n

    Install apache, php5.6 ubuntu<\/a><\/p>\n

    Install Nginx, Php, MariaDB on Ubuntu 16.04.1<\/a><\/p>\n

    Implementation:<\/h5>\n

    Login to the server as root. As updated earlier, this post assumes that nginx is installed on the webserver.<\/p>\n

    Add the key to the server.<\/p>\n

    curl http:\/\/repo.varnish-cache.org\/debian\/GPG-key.txt | sudo apt-key add -<\/code><\/p>\n

    Add the varnish repo to the server.<\/p>\n

    echo \"deb http:\/\/repo.varnish-cache.org\/ubuntu\/ lucid varnish-3.0\" >>\/etc\/apt\/sources.list<\/code><\/p>\n

    Run the update<\/p>\n

    apt-get update<\/code><\/p>\n

    Install varnish on the server.<\/p>\n

    apt-get install varnish<\/code><\/p>\n

    Open the file\u00a0\/etc\/default\/varnish\u00a0<\/em> and edit the following files.<\/p>\n

    nano \/etc\/default\/varnish<\/code><\/p>\n

    DAEMON_OPTS=\"-a :6081 \\<\/code><\/p><\/blockquote>\n

    to<\/p>\n

    DAEMON_OPTS=”-a :80 \\<\/p><\/blockquote>\n

    Edit the file\u00a0\/etc\/systemd\/system\/multi-user.target.wants\/varnish.service\u00a0<\/em> to use port from 6081 to 80.<\/p>\n

    <\/code>nano \/etc\/systemd\/system\/multi-user.target.wants\/varnish.service<\/code><\/p>\n

    From<\/p>\n

    ExecStart=\/usr\/sbin\/varnishd -j unix,user=vcache -F -a :6081<\/span> -T localhost:6082 -f \/etc\/varnish\/default.vcl -S \/etc\/varnish\/secret -s malloc,256m<\/p><\/blockquote>\n

    To<\/p>\n

    ExecStart=\/usr\/sbin\/varnishd -j unix,user=vcache -F -a :80<\/span>\u00a0-T localhost:6082 -f \/etc\/varnish\/default.vcl -S \/etc\/varnish\/secret -s malloc,256m<\/p><\/blockquote>\n

    We can optionally edit the memory allocated to varnish. Incase of dedicated server, increase the memory depends on the RAM available.<\/p>\n

    Open the file\u00a0\/etc\/varnish\/default.vcl\u00a0<\/em> and add\/edit\/modify the file.<\/p>\n

    nano \/etc\/varnish\/default.vcl<\/code><\/p>\n

    backend default<\/span> {
    \n.host = “127.0.0.1”;
    \n.port = “8080”;
    \n}<\/p><\/blockquote>\n

    Edit the port on the nginx default configuration. Incase, if there are multiple domains then we may need to edit all the domain virtualhost. If the webserver is apache then edit the Listen section to use 8080 port(default installation location is\u00a0\/etc\/apache2\/apache2.conf).\u00a0<\/em>In our example, we are using nginx and default configuration is\u00a0\/etc\/nginx\/sites-available\/default.<\/em><\/p>\n

    nano \/etc\/nginx\/sites-available\/default<\/code><\/p>\n

    From<\/p>\n

    listen 80 default_server;
    \nlisten [::]:80 default_server;<\/p><\/blockquote>\n

    To,<\/p>\n

    listen 127.0.0.1:8080 default_server;
    \nlisten [::]:8080 default_server;<\/p><\/blockquote>\n

    Restart the services to make the changes into effect.<\/p>\n

    systemctl restart nginx<\/code><\/p>\n

    sytemctl restart varnish<\/code><\/p>\n

    Verification:<\/h5>\n
    To verify whether varnish is working on port 80 and nginx on port 8080 use the following commands,<\/h5>\n

    netstat -plan |grep -w 80|grep varnish<\/code><\/p>\n

    netstat -plan |grep -w 8080|grep nginx<\/code><\/p>\n

    TO verify from outside of the server, use curl command to get the result.<\/p>\n

    \u00a0curl -I IPaddress<\/code><\/p>\n

    Output of the command is mentioned which confirms that varnish implemented over nginx.<\/p>\n
