Title: consider raising the MaxClients setting
Post by: alexo on 2014-01-29, 02:59:36: Hello

After moving from Kloxo to Kloxo-Mr, but account cann't work properly and i'm getting this error

Code: [Select]
[Wed Jan 29 04:07:17 2014] [error] server reached MaxClients setting, consider raising the MaxClients setting

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.

Title: Re: consider raising the MaxClients setting
Post by: alexo on 2014-01-29, 03:45:00: Just a little explanation - i did fresh install of Kloxo-MR and restore my site (just only one site in this account) and databases.

Post by: MRatWork on 2014-01-29, 04:07:52: 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'.
Title: Re: consider raising the MaxClients setting
Post by: alexo on 2014-01-29, 04:29:01: Sorry MRatWork don't understand which file to copy and modify?

There isn't any /etc/apache /tpl/~lxcenter.conf.tpl file
Title: Re: consider raising the MaxClients setting
Post by: alexo on 2014-01-29, 04:37:45: 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

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.

Title: Re: consider raising the MaxClients setting
Post by: MRatWork on 2014-01-31, 15:30:20: 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.
Title: Re: consider raising the MaxClients setting
Post by: alexo on 2014-01-31, 15:35:30: I don't enabled - Enable Php 5.2 (use Php52s) As Secondary Php
Title: Re: consider raising the MaxClients setting
Post by: alexo on 2014-01-31, 15:37:35: So, what is your advice? try php 5.3 (btw which one? php53 or php53u)?
Title: Re: consider raising the MaxClients setting
Post by: MRatWork on 2014-01-31, 15:39:30: 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'.
Title: Re: consider raising the MaxClients setting
Post by: alexo on 2014-01-31, 15:46:36: 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 :-(

Post by: MRatWork on 2014-01-31, 16:06:21: Add 'AddHandler application/x-httpd-php52 .php' in .htacces file only need if you want running application in /home/<user>/<domain>/ under php 5.2 version. Without add this line that mean application will be running under php 5.3 version.

Server limit value should be greater than maxclient.
Title: Re: consider raising the MaxClients setting
Post by: MRatWork on 2014-02-21, 09:17:59: Because secondary dns using suphp, ownership and permissions are crucial factors. Run 'sh /script/fix-chownchmod' to fix this issue.
