[JesusGil]

Server info: Parallels Plesk v12.0.18 - CentOS 6.6 (Final) - PHP 5.3.3 (by default)

Hello,

I want to enable multiple PHP versions as shown in http://kb.odin.com/en/118378

I follow this procedure:

- Install PHP 5.6.4 on Plesk 11.5 & 12: https://gist.github.com/Stayallive/dbb91ffa6f0fc6ca6ac3

The installation is correctly but after change the PHP version of any website I have this error:

- (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server

I try restart and reconfigure the domain...

# tailf /var/www/vhosts/domain.tld/logs/error_log

Hi JesusGil,

please have a look at the KB - article: PHP Fastcgi mode does not work: Premature end of script headers ( KB - article 120 785 ) and follow the suggestions.

Thank you very much for your help.

I have reviewed this article and gives no solution to my problem.

Symptoms

1. (YES) A secondary PHP is not working while switching the PHP mode to fastcgi.

2. (NO) Apache logs show a memory error.

3. (NO) The Suexec log shows an error.


Cause

1. (NO) PHP is not compiled with fastcgi.
fastcgi-5.6.4 5.6.4 5.6.4 fastcgi /php/php-5.6.4/bin/php-cgi /php/php-5.6.4/etc/php.ini


2. (NO) There is not enough memory on the server.
total used free shared buffers cached
Mem: 3754 1899 1854 54 218 855
-/+ buffers/cache: 824 2929
Swap: 7812 0 7812

3. (NO) The domain php.ini may be customized manually or contain an error.
Is the generated by default. I review it and I don´t find any problem.
The config in plesk is by default too.

4. (NO) Check the permissions for the /etc/passwd file.
-rw-r--r--. 1 root root 4916 ene 13 18:59 /etc/passwd

Hi JesusGil,

for further investigations it is helpfull to include log - files and depending configuration files. You could as well turn on the DEBUG log - level mode, so that you may get more informations about the errors ( this can be done over several configuration files, mostly in the loglevel section ). Be aware that as well missing rewrite directives ( apache and/or nginx ) can cause your issue and please check as well your php5-fpm configuration files.

Parallels Plesk Panel for Linux services logs and configuration files ( KB - article: 111 283 )​

Locate your php5-fpm configuration folders ( "conf.d" and "pool.d" with i.e. : locate fpm/conf.d and/or locate fpm/pool.d )

Please use as well the Forum search and the Knowledge-Base search options, because there are really a lot of solutions, suggestions and work-arounds for nearly all cases/failures

I have walked through the http://kb.odin.com/120785, but also everything is okay.

Haven't been able to find a solution for this problem, so I'm hoping there will be a solid fix anytime soon.
