multiple php-fpm versions on ispconfig: switch php-version error

CentOS Linux release 7.1.1503 (Core)
ISPConfig version is 3.0.5.4p8

Issue:
When switching php-fpm versions from Default (5.4.16) to php7RC4, ispconfig doesnt properly restart phpRC4-fpm to pick up the new pool. I need to restart phpRC4-fpm manually once. On the reverse switch of php-versions from RC4 to php5.4, something similar happens. Pools are correctly adjusted, but apparently php7RC4-fpm is not restarted, thus keeping the old pool, which listens on the approbriate socket. Therefore php-fpm 5.4.16 can not start. To fix this, I have to restart both services: php7RC4-fpm and php-fpm.
Bottom line: version switch by ispconfig doesnt really work automatically, but lacks a restart

What I checked:
1. created an initd script
2. name and patch of initd script is correct in ispconfig
3. pools are properly rewritten by ispconfig in both php-fpm
4. tested my init script and systemd config: by service, directly and systemctl - all ok

What I did before:
- compiled and installed php7RC4 in seperate directory ( /opt/phpRC4 )
- added php7RC4-fpm data to ispconfig as new php-Version

No clue whats going on Please help

 

Tried the same with an additional php-version: php5.6.14 and same issue: ispconfig can not switch from Default to php5.6 and back. Apparently a restart of the additional php versions to activate or deactivate pool does not happen when needed.

 

OS is CentOS 7.1 with systemd. Yet I created the init scripts since both still work together on 7.1

In log/messages I only see the default php-fpm restarted, all other fpm's are aparently not restarted.

How does ispconfig3 restart the php-fpm of additional php-versions? What is needed to successfully restart fpm of additional php-versions?

Also I dont see a logfile for ispconfig.

 

PS: Yes I also verified on the tutorials, yet had to stray from those since its CentOS 7.1

 

Thank you - got that one. Question: how does ispconfig know, which systemd-service corresponds to which php-version? Apparently some name or similar do not match, so that ispconfig doesnt know which service it is.

 

Or do I just enter the path tot he systemd config file in ispconfig under: Path to the PHP-FPM init script ?

 

status:
- the systemd-files are created: phpRC4-fpm.service and php-5.6-fpm.service
- all init scripts do exist and work for each fpm
- can use the fpm-services normally with systemctl

 

Turns out ispconfig3 has issues with multiple php-fpm versions under CentOS7.

Code:

                                        // And the next workaround, php-fpm reloads in centos 7 downt work as well.
                                        if(preg_match('/^ID=centos/m', $tmp) && preg_match('/^VERSION_ID="7"/m', $tmp)) {
                                                $initcommand = 'systemctl restart php-fpm.service';
                                        }
                                        unset($tmp);

Bottom line: ispconfig3 only accesses php-fpm.service. Any other service files for php-fpm are ignored.

Suggestion:
- bugfix for ispconfig adding another field to enter systemd service name

 

Hi. I have same issues with multi PHP-FPM installation on my CentOS7 with systemd.
I fix problem by changing function restartPHP_FPM in /usr/local/ispconfig/server/mods-available/web_module.inc.php
Usefull variable is a $init_script. I make systemd reload string based on it.
$initcommand = 'systemctl reload '.substr(strrchr($init_script,'/'),1);

Code:

       function restartPHP_FPM($action = 'restart') {

                global $app, $conf;

                // load the server configuration options
                $app->uses('getconf,system');
                $web_config = $app->getconf->get_server_config($conf['server_id'], 'web');

                list($action, $init_script) = explode(':', $action);

                if(!$init_script){
                        //$init_script = $conf['init_scripts'].'/'.$web_config['php_fpm_init_script'];
                        $initcommand = $app->system->getinitcommand($web_config['php_fpm_init_script'], $action);
                } else {
                        $path_parts = pathinfo($init_script);
                        $initcommand = $app->system->getinitcommand($path_parts['basename'], $action, $path_parts['dirname']);

                        if($action == 'reload' && $init_script == $conf['init_scripts'].'/'.$web_config['php_fpm_init_script']) {
                                // we have to do a workaround because of buggy ubuntu fpm reload handling
                                // @see: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1242376
                                if(file_exists('/etc/os-release')) {
                                        $tmp = file_get_contents('/etc/os-release');
                                        if(preg_match('/^ID=ubuntu/m', $tmp) && preg_match('/^VERSION_ID="14\.04"/m', $tmp)) {
                                                $initcommand = '/sbin/start-stop-daemon --stop --signal USR2 --quiet --pidfile /var/run/php5-fpm.pid --name php5-fpm';
                                        }
                                        // And the next workaround, php-fpm reloads in centos 7 downt work as well.
                                        //if(preg_match('/^ID=centos/m', $tmp) && preg_match('/^VERSION_ID="7"/m', $tmp)) {
                                        //      $initcommand = 'systemctl restart php-fpm.service';

                                }
                        }

                }

                $retval = array('output' => '', 'retval' => 0);
                exec($initcommand.' 2>&1', $retval['output'], $retval['retval']);
                $app->log("Restarting php-fpm: $initcommand", LOGLEVEL_DEBUG);
                return $retval;
        }
