[Plugin] nginx reverse proxy for apache2
 

Hi HowToForge'ers

I have now been playing a longer time with nginx and the try, putting it in front of apache2 as a reverse proxy.

In general it is not that hard, but to get it play nicely together with ISPConfig isn't so easy.

I already had two "working" variants. One of them was with a universal default nginx server, doing a DNS lookup and choosing the proxy_pass server based on it - well, I just didn't like this and it had some problems.

Secondly, I tried with nginx "vhosts" per site etc. like ISPConfig does it for apache2, but I had problems with folder protection etc. since I was trying to serve static files directly through nginx.

What I want to do now, is presenting you my last try. It's not finished yet, but it already has some working code.

I also tried to create it on a "modular" base with PHP classes (I'm not a programmer anyway) so these parts can be reused within other plugins.

So for example we have the "vhost" class which does nothing other than handle everything related with vhost files.

There is something similar with the cert class, handling ssl...

Yep, it might be the best if you would just take a look. Contributions are very welcome!

Renamed GitHub repo, new location at: https://github.com/Rackster/ispconfi...-reverse-proxy
added vhost backup

Does this still work "as is" in Debian squeeze and ispconfig 3.0.4.6 following instructions in https://github.com/Rackster/ispconfi.../Installation?

I can't find the following:

so we can modify the copy (which is much more safer):

nano /usr/local/ispconfig/server/conf-custom/vhost.conf.master

and replace the correct parts (you'll find them) with:

<tmpl_if name='ssl_enabled'>
<VirtualHost {tmpl_var name='ip_address'}:445>
<tmpl_else>
<VirtualHost {tmpl_var name='ip_address'}:82>
</tmpl_if>

Thank you!

Hi Davide

The plugin still works as of version 3.0.4.6.

the file itself (/usr/local/ispconfig/server/conf-custom/vhost.conf.master) gets copied a step above, e.g. you copy the file from ../conf to conf-custom.

Afterwards the part you have to replace with the one provided looks something like:

<VirtualHost {tmpl_var name='ip_address'}:{tmpl_var name="port"}>

I've been searching for two "port" to replace, evidently with no success.

So have I to replace that only one line with the code you provides?

Thank you!

Hi

Yes, the code you have to replace is on line 9:

It's only one because ISPConfig loops two times through the template filing the port variable with 2 values (just that you understand how it works normally). The replacement (as stated in the install guide on Github) kind of "destroys" this loop for thiis specific variable (port).
