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 performed

  • 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

  1. follow instructions on VCL 2.2 (unreleased) Release page to download and verify apache-VCL-2.2-incubating.tar.bz2 and put in in /root
  2. extract VCL 2.2 code 
    tar xjf apache-VCL-2.2-incubating.tar.bz2

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.

mysqldump vcl > ~/vcl-pre2.2-upgrade.sql

Update mysql schema

This step updates the mysql schema.

cd /root/apache-VCL-2.2-incubating
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 your configuration changes. These instructions assume that you installed the vcl web code at /var/www/html/vcl. If you installed it elsewhere, replace /var/www/html/vcl with your vcl web root.

  1. copy your old code out of the way 
    cd /var/www/html
mv vcl ~/vcl_2.1_web
  2. copy the new code in place 
    cd /root/apache-VCL-2.2-incubating
cp -r web /var/www/html/vcl
  3. copy your 2.1 config files 
    cd ~/vcl_2.1_web/.ht-inc
cp conf.php secrets.php pubkey.pem keys.pem /var/www/html/vcl/.ht-inc
  4. add the following new entries to conf.php - You can copy them in from .ht-inc/conf-default.php. Descriptions of each item can also be found in conf-default.php
    • date_default_timezone_set('America/New_York');
    • $blockNotifyUsers = "adminuser@example.org";
    • define("SCHEDULER_ALLOCATE_RANDOM_COMPUTER", 0);
    • define("DOCUMENTATIONURL", "https://cwiki.apache.org/VCLDOCS/");
    • define("USEFILTERINGSELECT", 1);
    • define("FILTERINGSELECTTHRESHOLD", 1000);
    • define("DEFAULTTHEME", 'default');

Start httpd service

service httpd start or /etc/init.d/httpd start

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/
cp -r vcl ~/vcl_2.1_managementnode
  1. Copy 2.2 code base to /usr/local 
    /bin/cp -r /root/apache-VCL-2.2-incubating/managementnode/* /usr/local/vcl
  2. Make changes related to vcld.conf settings
    1. Open VCL web interface
    2. Go to Management Nodes
    3. Select Edit Management Node Information
    4. Select Edit.
    5. Set any relevant fields:
    6. SysAdmin Email Address(es) - comma delimited list of vcl admin email addresses
    7. Address for Shadow Emails - a shared mail box, optional it receives email of all notifications
    8. Public NIC configuration method - Defines what type of NIC configuration is used, options are dynamic DHCP, Manual DHCP, or static
    9. End Node SSH Identity Key Files

Start vcld service

service vcld start or /etc/init.d/vcld start
