Hi, I am running few servers with Nginx, PHP-FPM and ISPConfig 3.0.5.4p1 mostly on Debian and Ubuntu. But I had some problems on one of my servers where all of my websites are almost identical(except some .php config files). What I can see is that I have wrong files executed by websites which they don't belong to. For example website web4 is showing some errors in my error log about .php files of web3. Also some informations from database which should be printed just by web3 are also printed by web4. This depends on which site I visit as first. This is what I tried so far: spinned 2 new virtual servers with different OS(Ubuntu 14.04 and Debian 7) and different repositories checked all configuration files (but have not touched any of them) Checked if this is problem of APCu or ZendOpzimizer (problems were still there after I disabled both of them) So I am wondering if this has to do something with PHP-FPM sockets on which these sites are listening. Software I am using: nginx 1.6.0 PHP-FPM 5.5.12 with APCu and ZendOptimizer enabled I really hope you can help me somehow and I hope you understand me.
I had some problems with ZendOptimizer on shared environments. You might want to disable that one and try again. My problems were not related to yours, but it may be worth a try..
Thank you very much for your response but that didn't help. I have error 502 on the one of the sites ... No errors in nginx error log or in php-fpm log ... just some error in logs of one of the sites "upstream sent too big header while reading response header from upstream". But I fixed this right away. Still nothing really changed. Problems persists. Web2 is trying to access files of web1 and failing badly. If I access web1 as first than web1 is trying to include files of web2, etc. ... I really hope you can give me some another advice because I don't know what to do anymore. Thank you very much for your time again.
I experienced a similar problem http://www.howtoforge.com/forums/showthread.php?t=64083 Solution was to make sure you've got your nginx directive for each site pointing to the correct port.
First thank you very much for trying to answer my question. The problem is I have my PHP processes listening on sockets. I will switch back to listening on port and see if it solves the problems (even though it doesn't really solves it ... I would like them to listen on unix sockets for various reasons). Anyway I just tried it and same things are happening again. So what you have done is that you changed port in all of your configs to 9000? Right?
The port has to be changed to the right port of the php-fpm instance of the website. Each website ahs its own php-fpm instance and eaxh of this instances has its own port. so if you use any custom nginx recipes that connect to the php-fpm server, then your code has to use the right port or your scripts will get executed under a wrong user and wont work as this wrong user has no permissions in the website.
They have right ports in their vhost configuration files. They are same as their ID in ISPConfig panel. Same if I am using sockets. Everything is correctly set up. But I still have these problems. I am not sure what I can try now. I think it is time to remove panel and do it with bare hands
The panel is not the problem here as the same panelworks flawlessly on ten thousands of nginx servers worldwide and the panel just writes the config files and you siad yourself that they contain no faults. If you think that sockets are the problem here, then compare the sockets paths in the vhost files with the ones in the php fpm pools.
But the problem with the panel here is that they may be "doing things you don't know about" or don't need to know. Many things are there just working and I don't care about them. I don't really know how it is configured by ISPConfig and I don't have to. Because of that there can be problems like this which I can't solve if I don't see "deeper" to problems. Don't take it personally. ISPConfig is one of the best panels out there and that is why I chose it. Thank you very much for creating such a great product. Back to the problem. They are all configured properly ... that's why I don't know what to try to do now.
Did you use any binary caches in php or do you use memcache or any other caches that might be shared between your websites?
I am using just Zend Optimizer+ with default configuration as opcache and APCu as user data cache. I think we can say APCu is not doing any harm as my problems are beyond the data if I see wrong files included.
You should try to turn the caches off. ispconfig is not doing any "magic" in that setup, it just writes the fpm pool conf file and the nginx vhost file for a site. The other things are just to create directories. So if the pool conf an nginx vhost are correct, then the problem must be somewhere else, it is most likely something that has been added additionally to the default perfect setup as this setup is used on thousands of servers and your problem has not been reported by other users.
maybe one thing that you could chec if any symlinks point to a wrong site. The directories in /var/www/ with the domain name are symlinks to the real directories. maybe one of that points to a wrong target.
I checked symlinks and I think there are no problems with them.
