Re: [users@httpd] Cannot troubleshoot php-fpm with apache
It is a php issue, can't tell you much about it.. php-fpm belongs to php.net. In case nobody else can assist you here, the php community will probably help you better regarding php issues. 2017-08-08 13:04 GMT+02:00 Nikolaos Milas : > On 8/8/2017 1:55 μμ, Nikolaos Milas wrote: > >> Any ideas? > > > In case this helps, here: http://iweb.noa.gr/files/phpinfo.htm you can find > the php info page of the server. > > > Nick > > - > To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org > For additional commands, e-mail: users-h...@httpd.apache.org > -- Daniel Ferradal IT Specialist email dferradal at gmail.com linkedin es.linkedin.com/in/danielferradal - To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org

Latest information about the case:
I now once more browsed the above file (namei -mol
/var/log/php-fpm/www-error.log) and I found one single PHP entry about
this website, with the following content:
--

...
So, even this one entry means that THERE IS (at least some) PHP logging
about this website!
But: Why there is only one entry about this website? Why there is no
other error logged? Could php-fpm somehow be "blacklisting" the website
PHP application (WordPress) due to this (and possible other) errors? Why
no debugging info is constantly logged?
Any ideas?
Thanks,
Nick

Re: [users@httpd] Cannot troubleshoot php-fpm with apache
yes, php values can't be defined in apache config, you define them in the fpm pool. IIRC the php-fpm error logs get written with the user the fpm pool has defined, in your case "apache" should have write permissions in the /var/log/php-fpm/ to be able to write www-error.log. about php configurations, yes, just define them in each pool and create one pool for each different case you need, that's what php-fpm is all about. 2017-08-08 9:42 GMT+02:00 Nikolaos Milas : > On 8/8/2017 9:47 πμ, Daniel wrote: > >> php_ directives belong to "mod_php" if you are proxying to php-fpm >> through fastcgi all related php logging and defined variables belong >> in the corresponding FPM pool. >> >> I would start by seeing what php-fpm has to say about those connections. > > > Thank you Daniel, > > You mean that the php_flag and php_value settings in the vhost configuration > will not apply? > If so, how can I pass particular php_value settings on a per vhost basis? > > As I wrote, the problem is that I don't see any php logging even in the > php-fpm logs for this vhost! > > For your reference, I am also including the php-fpm configuration, in case > you (or anyone) can advise me on something: > ># cat /etc/php-fpm.d/www.conf > >include=/etc/php-fpm.d/*.conf > >[global] >pid = /run/php-fpm/php-fpm.pid > >error_log = /var/log/php-fpm/error.log >log_level = debug >daemonize = yes > >[www] > >user = apache >group = apache > >listen = 127.0.0.1:9000 >listen.allowed_clients = 127.0.0.1 > >pm = dynamic >pm.max_children = 50 >pm.start_servers = 2 >pm.min_spare_servers = 2 >pm.max_spare_servers = 4 >pm.process_idle_timeout = 10s; >pm.max_requests = 500 >pm.status_path = /fpm-status > >slowlog = /var/log/php-fpm/www-slow.log >request_slowlog_timeout = 5s >request_terminate_timeout = 20s > >catch_workers_output = yes > >security.limit_extensions = .php .php3 .php4 .php5 .php7 .htm .html > >php_admin_value[error_log] = /var/log/php-fpm/www-error.log >php_admin_flag[log_errors] = on >php_value[session.save_handler] = files >php_value[session.save_path]= /var/lib/php/session >php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache > >php_admin_value[post_max_size] = 40M >php_admin_value[short_open_tag] = On > >php_value[date.timezone] = "Europe/Athens" > > Thanks, > > Nick > > - > To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org > For additional commands, e-mail: users-h...@httpd.apache.org > -- Daniel Ferradal IT Specialist email dferradal at gmail.com linkedin es.linkedin.com/in/danielferradal - To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org

Re: [users@httpd] Cannot troubleshoot php-fpm with apache
php_ directives belong to "mod_php" if you are proxying to php-fpm
through fastcgi all related php logging and defined variables belong
in the corresponding FPM pool.
I would start by seeing what php-fpm has to say about those connections.
