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

    CentOS Linux release 7.1.1503 (Core)
    ISPConfig version is

    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

    You have to add a systemd unit then as ispconfig will use systemd when it is installed. See here for an example on how such a systemd unit can look like:

    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 ?
  9. Member

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

    - 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/
    Usefull variable is a $init_script. I make systemd reload string based on it.
    $initcommand = 'systemctl reload '.substr(strrchr($init_script,'/'),1);

           function restartPHP_FPM($action = 'restart') {
                    global $app, $conf;
                    // load the server configuration options
                    $web_config = $app->getconf->get_server_config($conf['server_id'], 'web');
                    list($action, $init_script) = explode(':', $action);
                            //$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:
                                    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/ --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)) {
                                            //      $initcommand = 'systemctl restart php-fpm.service';
                            if($action == 'reload') {
                                    //And the next workaround, php-fpm reloads in centos 7 downt work as well.
                                    if(file_exists('/etc/os-release')) {
                                            $tmp = file_get_contents('/etc/os-release');

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