Site Infrastructure

Tuesday 06 November 2012 9:53:29 pm - 3 replies

Hi there,

I am working for a company where we use ezp extensively. We have around 70 sites built on ezp. Currently we have all these sites sitting in one installation of ezp (Multisite setup). We use deployment scripts to deploy and update sites. 

We also have extension repository that these sites depend on. (Not all sites need all the extensions...but they are available if they do need them)

Problem we are having, because an extension can be used by any Site A and Site B in the list of 70, updating an extension with this setup for just Site A is proving to be impossible.

I was wondering if any of the users in the community is using this sort of setup and have any ideas in improving the infrastructure.

Just to give you an idea, the setup we have is

Ezp core


All our sites sit in


All our extensions also sit in


Looking for better infrastructure

Why not name extensions according to their version?

eg: my_ext_1_1, my_ext_1_2

Note: this has the disadvantage that you need to alter all the ini files within the extension where the extension name is present.

Or you could use separate ez installations for the different customers, and use symlink to share most files:

- have every site use one physical, different root directory

- share the whole kernel, design directories between all sites, by using symlinks (/var/www/site1/kernel => /var/ez_core/kernel)

- share versioned extensions using symlinks (var/www/site1/extension/myext => /var/ez_core/extension/myext_1.1)

This allows you not only to upgrade extensions but also ez, separately for every site.

The downside is that cache files will be generated fully for every site (you might be sharing caches just a bit more now).

Other benefits: you get separate logs for every site

ps: teh above answer is for the different-extension-versions-on-different-sites problem.

to have an extension enabled only on one (or more) siteaccess is easy: just use the siteaccessextension setting
