Summary0001653: php-fpm72 crashes at start when loading xdebug.so
Description

If I add
zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20170718/xdebug.so
to /opt/alt/php-fpm72/usr/php/php.ini
php-fpm72 stops working.
From the command line
/opt/alt/php-fpm72/usr/sbin/php-fpm with any of -v -t -i gives no output and no error.

If I start php-fpm as a service I get the following output:
php-fpm72.service - The PHP FastCGI Process Manager
Loaded: loaded (/usr/lib/systemd/system/php-fpm72.service; enabled; vendor preset: disabled)

Hi,

I'm going to need some more information, as Xdebug works fine with PHP-FPM for me.

Can you provide the following information:

  • The contents of the PHP-FPM log file, the output from systemd's service tools does not say anything besides "it didn't work"
  • Check whether the output of "sudo dmesg" just after trying to start PHP-FPM says something about a Segmentation Fault
  • What does running the command by hand say on the shell as root say? This one: /opt/alt/php-fpm72/usr/sbin/php-fpm --nodaemonize --fpm-config /opt/alt/php-fpm72/usr/etc/php-fpm.conf

cheers,
Derick

  • nothing in /opt/alt/php-fpm72/usr/var/log/php-fpm.log

  • /var/log/messages:

Apr 5 08:23:58 vps systemd: Started The PHP FastCGI Process Manager.
Apr 5 08:23:58 vps systemd: php-fpm72.service: main process exited, code=exited, status=254/n/a
Apr 5 08:23:58 vps systemd: Unit php-fpm72.service entered failed state.
Apr 5 08:23:58 vps systemd: php-fpm72.service failed.

  • sudo dmesh: nothing relvant to php-fpm, php or xdebug.

  • zend_extension commented out and php-fpm service started:
    /opt/alt/php-fpm72/usr/sbin/php-fpm --nodaemonize --fpm-config /opt/alt/php-fpm72/usr/etc/php-fpm.conf
    [05-Apr-2019 11:29:40] ERROR: An another FPM instance seems to already listen on /opt/alt/php-fpm72/usr/var/sockets/cwpsvc.sock
    [05-Apr-2019 11:29:40] ERROR: FPM initialization failed

zend_extension uncommented and php-fpm stopped:

/opt/alt/php-fpm72/usr/sbin/php-fpm --nodaemonize --fpm-config /opt/alt/php-fpm72/usr/etc/php-fpm.conf

No output as it happens when using -i, -v, -t or any other option.

Thank you
maxx
