+This page provides information on how to upgrade from VCL 2.2 to VCL 2.3.
Please note it only applies for the upgrade from 2.2 to 2.3, this may or may
not work for other versions.
+
+**The basic steps that will be performed**
+
+ - 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
+
+# Detailed steps for upgrade from 2.2.1 to 2.3 #
+
+1. follow instructions on VCL 2.3 Release page to download and verify
apache-VCL-2.3.tar.bz2 and put in in /root
+2. **extract VCL 2.3 code**
+
+ :::BashLexer
+ tar xjf apache-VCL-2.3.tar.bz2
+
+3. **Shutdown** the httpd and vcld services
+
+ :::BashLexer
+ service httpd stop or /etc/init.d/httpd stop
+ service vcld stop or /etc/init.d/vcld stop
+
+4. We will **create a backup of the vcl database**. This will provide a
restore point if necessary.
+
+ :::BashLexer
+ mysqldump vcl > ~/vcl-pre2.3-upgrade.sql
+
+5. This step **updates the mysql schema**. *Note*: A new resource group is
added in update-vcl.sql - **all profiles**. Access to manage the group is added
to the VCL->admin node in the privilege tree if that node exists. If not, you
will need to add it manually after starting httpd again. To add it manually,
pick a node in the privilege tree, scroll to Resources, click Add Resource
Group, select serverprofile/all profiles from the drop-down box, check
available, administer, manageGroup, and manageMapping, and click Submit New
Resource Group.
+
+ :::BashLexer
+ cd /root/apache-VCL-2.3
+ mysql vcl < mysql/update-vcl.sql
+
+6. Grant CREATE TEMPORARY TABLES to mysql user
+The web code now requires access to create temporary tables in mysql. You need
to grant the user your web code uses to access mysql the "CREATE TEMPORARY
TABLES" permission. Look at the secrets.php file in your web code for the user
and hostname. For example, if your web code is installed at /var/www/html/vcl,
your secrets.php file would be /var/www/html/vcl/.ht-inc/secrets.php. Look for
$vclhost and $vclusername. The secrets.php file might have something like:
+
+
+ :::BashLexer
+ $vclhost = 'localhost';
+ $vcluser = 'vcluser';
+
+7. Then, you need to issue the grant command to mysql. Using the values from
above as examples, connect to mysql and then issue the grant command:
+
+ :::BashLexer
+ mysql
+ GRANT CREATE TEMPORARY TABLES ON `vcl`.* TO 'vcluser'@'localhost';
+ exit
+
+8. **Update the web code**. This step we will move the 2.2 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.
+
+ :::BashLexer
+ cd /var/www/html
+ mv vcl ~/vcl_2.2_web
+
+9. **Copy the new code** in place
+
+ :::BashLexer
+ cd /root/apache-VCL-2.3
+ cp -r web /var/www/html/vcl
+
+10. **Copy your 2.2 config files**
+
+ :::BashLexer
+ cd ~/vcl_2.2.1_web/.ht-inc
+ cp conf.php secrets.php pubkey.pem keys.pem /var/www/html/vcl/.ht-inc
+
+11. **Make the maintenance directory writable by the web server user**.
Normally this is the apache user, if using a different user change below cmd
accordingly.
+
+ :::BashLexer
+ chown apache /var/www/html/vcl/.ht-inc/maintenance
+
+12. **Make changes to conf.php**:
+
+ a. A new user group permission that controls who can manage block
allocations globally or for a specific affiliation has been added. It can be
granted to any user group under Privileges->Additional User Permissions->Manage
Block Allocations. Users with this permission are notified of new block
allocation requests. **Remove the following from conf.php**.
+
+ :::BashLexer
+ $blockNotifyUsers
+
+
+ b. A new user group permission that controls who can look up users
globally or for a specific affiliation has been added. It can be granted to any
user group under Privileges->Additional User Permissions->User Lookup. Users
with this permission can look up information about other users. **Remove the
following from conf.php**
+
+ :::BashLexer
+ $userlookupUsers
+
+ c. **Multilingualization** has been added VCL. So, **DEFAULTLOCALE** has
been added to conf.php to set the default locale. **Add the following to
conf.php**, changing en_US if needed to match your locale. You can look in
/var/www/html/vcl/locale to see which ones are available.
+
+
+ :::BashLexer
+ define("DEFAULTLOCALE", "en_US");
+
+
+ d. Users authenticated using Shibboleth without also having an LDAP server
can now be added before they log in. **Add the following to conf.php** 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.
+
+
+ :::BashLexer
+ define("ALLOWADDSHIBUSERS", 0);
+
+
+ e. LDAP related items have been simplified in the code using additional
options in $authMechs. For any LDAP entries, 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'). In conf.php,
**Add the following to each LDAP** array you have in the $authMech array.
+
+ :::BashLexer
+ "lookupuserbeforeauth" => 0,
+ "lookupuserfield" => '',
+
+
+ f. The way the authentication functions toward the bottom of conf.php are
initialized has been simplified. Make the following changes:
+
+ :::BashLexer
+ REMOVE
+ $affilValFunc
+ $affilValFuncArgs
+ $addUserFunc
+ $addUserFuncArgs
+ $updateUserFunc
+ $updateUserFuncArgs
+
+ ADD
+ $affilValFunc = array();
+ $affilValFuncArgs = array();
+ $addUserFunc = array();
+ $addUserFuncArgs = array();
+ $updateUserFunc = array();
+ $updateUserFuncArgs = array();
+ foreach($authMechs as $key => $item) {
+ if($item['type'] == 'ldap') {
+ $affilValFunc[$item['affiliationid']] = 'validateLDAPUser';
+ $affilValFuncArgs[$item['affiliationid']] = $key;
+ $addUserFunc[$item['affiliationid']] = 'addLDAPUser';
+ $addUserFuncArgs[$item['affiliationid']] = $key;
+ $updateUserFunc[$item['affiliationid']] = 'updateLDAPUser';
+ $updateUserFuncArgs[$item['affiliationid']] = $key;
+ }
+ elseif($item['type'] == 'local') {
+ $affilValFunc[$item['affiliationid']] = create_function('',
'return 0;');
+ $addUserFunc[$item['affiliationid']] = create_function('',
'return NULL;');
+ $updateUserFunc[$item['affiliationid']] =
create_function('', 'return NULL;');
+ }
+ }
+
+
+13. **Restart httpd service**
+
+ :::BashLexer
+ service httpd start or /etc/init.d/httpd start
+
+14. **Update management node code** This step will make a backup copy of the
2.2 vcl code base and then copy the new code over the existing code to preserve
any drivers or other files you've added.
+
+ :::BashLexer
+ cd <your vcl MN code root path>
+ ie. cd /usr/local/
+ cp -r vcl ~/vcl_2.2_managementnode
+
+15. **Copy in the 2.3 code base to /usr/local**, copying in should preserve
any drivers or other files you've added.
+
+ :::BashLexer
+ /bin/cp -r /root/apache-VCL-2.3/managementnode/* /usr/local/vcl
+
+16. **Run install_perl_libs.pl** to add any new perl library requirements:
+
+ :::BashLexer
+ /usr/local/vcl/bin/install_perl_libs.pl
+
+17. **Restart vcld service**
+
+ :::BashLexer
+ service vcld start or /etc/init.d/vcld start
+
+18. Make some test reservations and watch the vcld.log to verify everything is
working correctly.
+
+ :::BashLexer
+ tail -f /var/log/vcld.log
