This file provides information on how to upgrade from VCL 2.1 to VCL 2.2. Please note it only applies for the upgrade from 2.1 to 2.2, this may or may not work for other versions.

The basic steps that will be preformed

  • Download and Extract 2.2 code
  • Shutdown httpd and vcld services
  • Create backup of vcl database
  • Update mysql schema
  • Update Web code, create a backup, copy in new, make changes
  • Update Management node vcl code, create a backup, copy in new, make changes
  • Restart httpd and vcld services

Download and Extract 2.2 code

download to /root/vcl_2.2

Shutdown services

Shutdown the httpd and vcld services

service httpd stop or /etc/init.d/httpd stop
service vcld stop or /etc/init.d/vcld stop

Create a backup of vcl database

We will create a backup of the vcl database. This will provide a restore point if necessary.

mysql dump command

Update mysql schema

This step updates the mysql schema.

cd to vcl2.2 source directory
cd /<path to vcl 2.2 source> 

mysql vcl < mysql/update-2.2.sql

Update web code

This step we will move the 2.1 web directory out of the way, so we can copy in the new web code base. After copying in the new code, we will migrate any of your configuration changes, etc.

  1. cd <your vcl web root> i.e. cd /var/www/html 
    mv vcl vcl_2.1_web
  1. copy your 2.1 config files 
    cp vcl_2.1_web/.ht-inc/conf.php vcl/.ht-inc/conf.php
....

Update management node code

This step will move the 2.1 vcl code base out of the way, so we can cleanly copy in the new management node(MN) code.

  1. Copy 2.1 code base to a backup location 
    cd <your vcl MN code root path>
ie. cd /usr/local/
mv vcl vcl_2.1_management_node
  1. Copy 2.2 code base to /usr/local 
    cp -r /root/vcl_2.2 /usr/local/vcl
  1. Make changes related to vcld.conf settings
    Open VCL web interface (assumes httpd has been restarted)
    Go to Management Nodes
    Select Edit Management Node Information
    Select Edit.
    Set any relevant fields:
    SysAdmin Email Address(es) - comma delimited list of vcl admin email addresses
    Address for Shadow Emails - a shared mail box, optional it receives email of all notifications
    Public NIC configuration method - Defines what type of NIC configuration is used, options are dynamic DHCP, Manual DHCP, or static
