Plesk migration issues

[Christian Selten]

While trying to migrate the plesk from one centos server to another I'm getting some messages that I need to resolve before I can migrate.

The details of the servers
Source server:

• CentOS release 6.4 (Final)
• Plesk 12.0.18 Update #80
• httpd 2.2.15-31.el6.centos
• mod_python 3.3.1-14.el6.1
• mysql 5.1.73-3.el6_5
• php 5.3.10-1.el6

Destination server:

• CentOS Linux release 7.2.1511 (Core)
• Plesk 12.5.30 Update #27
• httpd 2.4.6-40.el7.centos
• php 5.4.16-36.el7_1
• mysql 5.5.44-2.el7.centos

Message I'm getting on the destination server

The following Apache modules are not installed on the destination server: authn_default, disk_cache, authz_default, authn_alias. Please install and enable these modules to prevent possible problems.
The following Apache modules are disabled on the destination server: cgi, php5. Please enable these modules to prevent possible problems.
The PHP handler 5.3 Apache module (id=module) is not available on the destination server. Instead, Plesk will use the following PHP handler: 5.4.16 FPM application served by Apache (id=fpm). To use the same PHP handler as on the source server, you should turn on or install it on the destination server.
The component mod_python is not installed on the destination server. mod_python will be unavailable for all restored objects.

I know mod_python isn't supported any more and there is a work around or an alternative.
There where more Apache modules that needed to be installed and enabled, I've fixed those.
Only these are left and I have no idea where to find them or how to fix it.
Can someone help to resolve this?

Hi Christian Selten,

please be informed, that the Plesk Knowledge-Base offers a wide range of solutions and work-arounds, even in different languages. You could have found there ( search word "authn_default" or "disk_cache" or "authz_default" or "authn_alias" ):

How to install and configure Apache modules? ( Plesk Knowledge-Base article 121064 )
​

To enable or disable a module, you could use the commands ( for CentOS/RHEL ):

• Search for enabled or disabled modules with:

cat /etc/httpd/conf/httpd.conf | grep LoadModule
cat /etc/httpd/conf/httpd.conf | grep #LoadModule

Change existing states on your destination server, to meet the source server configuration.

​

"mod_python" is available over the EPEL repos, please add it and afterwards the command "yum install mod_python" will install the desired component.



If you need further help, please replay again to your thread, so that people willing to help may investigate a possible issue/error/problem/failure with you and can make some suggestions.

I want to point out that mod_python isn't supported on centos 7. Like I said I've found the work around it.
The other I'll try. But that I've enabled and install other plugins without a problem, my gut feeling is saying it's not going to help much.
On the other hand if I only get one module installed this way, I'm one step closer.

Thanks for the reply so far.
