hepl error mod_fcgid when install zend opcache

any help guys ?
so After installing opcache and put the path on opache.ini
everything seems to be fine
when I check with php -v , I don't have any error and it tells me that zend opcache is installed
But when I try to access to my website or ispconfig panel I have an error.
I check the logs this is what I have :
[warn] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[warn] (104)Connection reset by peer: mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

Thank you for your help

 

Hello Till
thank you for your help
I'm using debian 6 with ispconfig php 5.3.3, fastcgi and suexec activated for my prestashop website
when I activated zend opcache, I can't access to my website and ispconfig panel too
and I have this error
[warn] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[warn] (104)Connection reset by peer: mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

thank you

 

thank you for your reply and your help till
but it not only about my website, I can't access to my ispconfig panel too when I activate opcache on /etc/php5/conf.d/opcache.ini
so what I see is that when I added zend_extension=/usr/lib/php5/20090626/opcache.so to /etc/php5/cgi/php.ini, the website works but I have 500 error when I try to access to my ispconfig panel
thank you

 

thank you for your reply till
so can you tell me please which fcgi ini file should I update with zend_extension=/usr/lib/php5/20090626/opcache.so
in order to have opcache installed in all websites and ispconfig
thank you

 

thank you again for your help till

so this is what I've tried
after installing zend opcache, I log in ispconfig panel,
I select my website and in "Custom php.ini settings" I added zend_extension=/usr/lib/php5/20090626/opcache.so
so when I checked my phpinfo file , it tells me that opcache is activated and running But I can't access to my website I have an error 500 and I have this on the logs
Connection reset by peer: mod_fcgid: error reading data from FastCGI server
Connection reset by peer: mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

so I decided to add zend_extension=/usr/lib/php5/20090626/opcache.so in /etc/php5/cgi/php.ini
after that my website is available I don't have error 500
but when I check phpinfo, I have the opcache config but it tell me that opcache is disabled and not running

I attached phpinfo directories

thank you for your help

 

I assume it's the order which is why it works the one but not the other way like you described.
Also remember you may need to adjust php.ini to actually activate it
http://php.net/manual/en/opcache.configuration.php#ini.opcache.enable

 

thank you for your reply
I tried this too :
After installing zend opcache, I created opcache.ini in /etc/php5/conf.d with zend_extension=/usr/lib/php5/20090626/opcache.so
when I checked it tell me that opcache is activated and running
but when I tried to access to my website and ispconfig panel, I have 500 error with this in error log
Connection reset by peer: mod_fcgid: error reading data from FastCGI server
Connection reset by peer: mod_fcgid: ap_pass_brigade failed in handle_request_ipc function
so I checked with cfgi, opcache.ini is in /etc/php5/cgi/conf.d
so I don't know where this error come from (only when opcache is activated)

thank you again

 

I'm not quite sure but I think it was debian 6, maybe 5 having very unstable mod_fcgi and unuseable mod_fastcgi support ( needed to manually load sources including later released patches ) .

Is mpm_prefork active? Any other opcode caches like APC/xcache/eAccelerator?
What happens if you create a test website using mod_php ( if installed ) and then enableing zend opcache.so does that work?

But honestly, the error messages are not helping much ( not your fault, software issue ) and debian 6 aswell the used php version are heavily outdated and unsupported - consider upgrading to at least debian 7 or maybe just stick with php-apc extension.

Is something like mod_security or php-suhosin enabled/loaded? Does it make a difference if disabled/unloaded?

 

thank you for your help ztk.me
I already tried APC (and new version APCu) and installed xcache too, but I noticed that there is no much difference
so that's why I tried to install opcache (more recent) in order to compare. But of course I dind't run all these cache at the same time.
Before installing opcache, I uninstalled apc and xcache.
I think the problem comes from mod_fcgid

I think I'll keep apcu

thank you again for your help

 

apcu is for php 5.5+ you probably can safely use apc - if you are using mpm_prefork + fcgi you won't benefit from opcode caching as much as you could if you use mpm_worker because prefork forks multiple threads each with its own (php-)module having its own opcode cache and security wise they can't communicate with each other leading to multiple needs of caching files. The more processes the less the chance having a cache-hit.

The downside would be you wouldn't be able to use any mod_php / suphp / mod_python and such - depending on your needs just remove then and check mod_fastcgi ( you might need to compile it from source and look for the latest patches which are not included in the packaged source but on the same download page ... well this has been a while I did that, have no link handy ).

In conclusion, consider using mpm_worker + mod_fastcgi + fpm ( might need some hacking / recompiling ), use php-apc for your older php version or .... go debian 7 and then 8 and use mod_fastcgi + worker + php-fpm from the stable repository.

If you need your old php-version you still can compile it from source + check patches and add it as additional php-version.
