...

The following instructions assume these tasks have previously been completed:


Your web server should meet the following criteria before installing the frontend VCL codeWeb Server:

  • Apache HTTP Server v1.3 or v2.x with SSL enabled - while VCL
  • PHP 5.0 or later
    Note: The VCL web frontend may run under another webserver other web server platforms capable of running PHP code, it but has only been tested to work with Apache HTTP Server.

Required Linux Packages:

  1. Frontend Web Code

    1. If you
    haven't
    1. have not already done so, download and extract
    a copy of the latest release. There is a link to it under the Project Resources section on our wiki home page. Look for "Current version".copy the "web" directory to a location somewhere
    1. the source files on the web server:
      Panel

      wget http://www.apache.org/dist/incubator/vcl/apache-VCL-2.2.1-incubating.tar.bz2
      tar -jxvf apache-VCL-2.2.1-incubating.tar.bz2

    2. Copy the web directory to a location under the web root of your web server: code
      Panel

    1. cp

    1. -r

    1. apache-VCL-2.2.1-incubating/web/

    1. /var/www/html/vcl

    copy/
    1. Copy or rename secrets-default.php to secrets.php
    modify
    1. :
      Panel

      cp /var/www/html/vcl/.ht-inc/secrets-default.php /var/www/html/vcl/.ht-inc/secrets.php

    2. Edit the secrets.php file:
      Panel

      vi /var/www/html/vcl/.ht-inc/secrets.php

  2. set $vclhost, $vcldb, $vclusername, and $vclpassword to match your database setup
      • Set the following variables to match your database configuration:
        • $vclhost
        • $vcldb
        • $vclusername
        • $vclpassword
      • Create random passwords for the following variables:
        • $mcryptkey
        • $mcryptiv (
    create random passwords for $mcryptkey, $mcryptiv, and $pemkey - $mcryptiv
        • must be 8 hex characters
    run
        • )
        • $pemkey
      • Save the secrets.php file
    2. Run the genkeys.sh script
    from within vcl/.ht-inc and give it $pemkey from
    1. , enter the value you set for $pemkey in secrets.php as the passphrase (3 times, copy/paste is a good idea
    here
    1. )
    1. Panel

      /var/www/html/vcl/.ht-inc/genkeys.sh

    2. Copy or

      Panel

      vi /var/www/html/vcl/.ht-inc/conf.php

      • COOKIEDOMAIN needs to be the domain name your web server is using
    ,

    it
      • the web server by its IP
    only.
      • address
    *

          optionally
            1. Optionally, fill in these

Then, the IP configuration on the nodes will be manually set using Public Netmask, Public Gateway, Public DNS Server, and the IP address set for the computer under Manage Computers
          click "
