This page provides information on how to upgrade from VCL 2.2.1 to VCL 2.3. Please note it only applies for the upgrade from 2.2.1 to 2.3, this may or may not work for other versions.
- Download and Extract 2.3 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
- Restart httpd service
- Update Management node vcl code, create a backup, copy in new, make changes
- Restart vcld service
Download and Extract 2.3 code
- follow instructions on VCL 2.3 Release page to download and verify apache-VCL-2.3-incubating.tar.bz2 and put in in /root
- extract VCL 2.3 code
tar xjf apache-VCL-2.3-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-pre2.3-upgrade.sql
Update mysql schema
This step updates the mysql schema.
cd /root/apache-VCL-2.3-incubating
mysql vcl < mysql/update-vcl.sql
Update web code
This step we will move the 2.2.1 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.
- move your old code out of the way
cd /var/www/html
mv vcl ~/vcl_2.2.1_web
- copy the new code in place
cd /root/apache-VCL-2.3-incubating
cp -r web /var/www/html/vcl
- copy your 2.2.1 config files
cd ~/vcl_2.2.1_web/.ht-inc
cp conf.php secrets.php pubkey.pem keys.pem /var/www/html/vcl/.ht-inc
- Make the maintenance directory writable by the web server user. You will need to know what user httpd runs as on your server. This can be found with
Look at the first column. One process will be owned by root. The remaining processes will be owned by the web server user. Now, own /var/www/html/vcl/.ht-inc/maintenance to that user (replacing 'apache' with your web server user if different):
chown apache /var/www/html/vcl/.ht-inc/maintenance
- make some changes to conf.php:
vi /var/www/html/vcl/.ht-inc/conf.php or nano /var/www/html/vcl/.ht-inc/conf.php
- $blockNotifyUsers has been replaced by a user group permission so it needs to be removed
- Multilingualization has been added VCL - so DEFAULTLOCALE has been to conf.php to set the default locale. Add
define("DEFAULTLOCALE", "en_US");
to your file, changing en_US if needed to match your locale. You can look in /var/www/html/vcl/locale to see which ones are available.
- Add the following definition:
define("ALLOWADDSHIBUSERS", 0);
If you are using Shibboleth and would like to be able to add users to groups before the user has ever logged in to VCL, you can set this to 1. However, please note that if you typo the userid, there is no way to verify it, and the user will be added with the typoed userid.
- some LDAP related items have been simplified in the code using some additional options in $authMechs. For any LDAP entries, you need to add two options. "lookupuserbeforeauth" is used if you need VCL to look up the full DN of a user and use that when doing the bind that authenticates the user (if you don't know what this means, leave it set to 0). If you need to set it to 1, then you will need to set "lookupuserfield" to what LDAP attribute to use when looking up the user's DN (typically either 'cn', 'uid', or 'samaccountname')
"lookupuserbeforeauth" => 0,
"lookupuserfield" => '',
- If you are using any Local accounts for authentication, you need to modify the entries for $addUserFunc and $updateUserFunc. Change
$addUserFunc[$item['affiliationid']] = create_function('', 'return 0;');
$updateUserFunc[$item['affiliationid']] = create_function('', 'return 0;');
to
$addUserFunc[$item['affiliationid']] = create_function('', 'return NULL;');
$updateUserFunc[$item['affiliationid']] = create_function('', 'return NULL;');
Restart httpd service
service httpd start or /etc/init.d/httpd start
Update management node code
This step will make a backup copy of the 2.2.1 vcl code base and then copy the new code over the existing code to preserve any drivers or other files you've added.
- Copy 2.2.1 code base to a backup location
cd <your vcl MN code root path>
ie. cd /usr/local/
cp -r vcl ~/vcl_2.2.1_managementnode
- Copy in the 2.3 code base to /usr/local, copying in should preserve any drivers or other files you've added.
/bin/cp -r /root/apache-VCL-2.3-incubating/managementnode/* /usr/local/vcl
- Run install_perl_libs.pl to add any new perl library requirements:
/usr/local/vcl/bin/install_perl_libs.pl
Restart vcld service
service vcld start or /etc/init.d/vcld start
