I need this php version (php52), and most of my sites  don't work well under Lighttpd and Nginx.

If i understand right, i must increase MaxClients in httpd.conf, but unfortunately i don't find how to do it.

--
Any advice will be appreciated.

[alexo]

Also the  the server responds very slowly :-(

[alexo]

Just a little explanation - i did fresh install of Kloxo-MR and restore my site (just only one site in this account) and databases.

[MRatWork]

Copy /etc/apache /tpl/~lxcenter.conf.tpl to custom.~lxcenter.conf.tpl and then modified this custom file. Better using 'Apache optimize' in 'webserver config'.

Remember, you can use nginx-proxy or lighttpd-proxy when using php 5.2 but need enable 'secondary php'.

[alexo]

Sorry MRatWork don't understand which file to copy and modify?

There isn't any /etc/apache /tpl/~lxcenter.conf.tpl file

[alexo]

Do you mean this file - /etc/httpd/conf.d/~lxcenter.conf

So i must do changes in this file? if yes, i don't understand why to modify custom file.

Regarding "nginx-proxy or lighttpd-proxy" - > few months ago i try to test with both this, but unfortunately this site don't work properly.

thank you

[MRatWork]

Sorry, I mean '/home/apache/tpl/~lxcenter.conf.tpl'.

[alexo]

Sorry, I mean '/home/apache/tpl/~lxcenter.conf.tpl'.

Sorry don't understand you right

Copy /home/apache/tpl/~lxcenter.conf.tpl to custom.~lxcenter.conf.tpl and then modified this custom file

Can you pls explain ?

So you mean, to get this .tpl file, make modifications and put where ? Left in the same folder or move to another folder?

What you mean "custom.~lxcenter.conf.tpl" - it's like custom name, if yes where i must put this file?

thank you.

[MRatWork]

The same folder, modified the content and then restart httpd service.

[alexo]

Ok. thx

What i did is ->

Code: [Select]

cp ~lxcenter.conf.tpl custom.~lxcenter.conf.tpl
nano custom.~lxcenter.conf.tpl

and make such modifications

[MRatWork]

When using php 5.2 (via 'secondary php') web will be slow because running under suphp.

Better using php 5.3 or 5.4 if possible with php-fpm_event and nginx-proxy. Certain application which designed in php 5.2 possible running in php 5.3 with some tricks.

[alexo]

I don't enabled - Enable Php 5.2 (use Php52s) As Secondary Php

[alexo]

So, what is your advice? try php 5.3 (btw which one? php53 or php53u)?

[MRatWork]

If possible don't choose 'php52' in 'php branch'. Possible have troubles with other packages (like mysql).

If possible, select 'php53u' and enable 'secondary php'.

[alexo]

Now php53u + php-fpm_event +   Enable Php 5.2  + AddHandler application/x-httpd-php52 .php' in .htaccess

500 internal server errror on all my sites :-(
