Troubleshooting php-fpm with apache on Centos 7

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hello,

I am running httpd-2.4.6-45.el7.centos.x86_64 with php-fpm-7.0.22-1.el7.remi.x86_64 (on CentOS 7).

My main problem: On this httpd server I have several vhosts running, but apparently I am facing intermittent problems with php-fpm communication on only one of them.

Most of the sites are WordPress or Joomla Applications (running with mysql). Everything seems right: low load, all websites are operating fine, except this one, but only intermittently.

The secondary problem is that I can't seem to be able to log php errors.

When the problem starts, the users receive "503 Service Unavailable" pages for many hours/days, and in the error log I see only such errors:

The problem is NOT resolved by restarting apache and/or php-fpm.

The config of the vhost is as follows:

   <VirtualHost *:80>
            DocumentRoot "/var/webs/wwwgreekgeo/www"

            ServerName www.greekgeo.noa.gr

            ServerAdmin webmaster@xxxxxx

            DirectoryIndex index.php index.html index.htm

            php_flag log_errors on
            php_flag display_errors off
            php_value error_log /var/webs/wwwgreekgeo/log/php_error_log
   #        php_value error_reporting 32767
   #        php_value error_reporting 2147483647
            php_value error_reporting 6135

            Redirect 301 /en.index.html http://www.greekgeo.noa.gr/wp/

            RewriteEngine on

            RedirectMatch ^/index.html$ /wp/

        <Directory "/var/webs/wwwgreekgeo/www">
            Options -Indexes +FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

            <Files ~ "^\.ht">
               Require all denied
            </Files>

        <FilesMatch \.php$>
            SetHandler "proxy:fcgi://127.0.0.1:9000"
        </FilesMatch>

        ErrorLog /var/webs/wwwgreekgeo/log/error_log
        LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
   \"%{User-agent}i\"" combined
        CustomLog /var/webs/wwwgreekgeo/log/access_log combined
        LogLevel debug

   </VirtualHost>

As you can see, I have made efforts to enable php debugging, but I still can't see any php logging, in any php log:

   /var/log/php-fpm/error.log
   /var/log/php-fpm/www-error.log
   The file: /var/webs/wwwgreekgeo/log/php_error_log remains empty

I've also followed these directions to enable Wordpress php logging: https://codex.wordpress.org/WP_DEBUG but I didn't get any php logging either.

Please advise: How can I enable full php logging and troubleshoot php on this vhost?

Also: What would you advise, if possible, on the particular problem (php processing hanging on this vhost only without any obvious reason)?

I've googled and tried many things for several hours, but I can't find a solution.

Thanks in advance,
Nick
