centos – Fixing php72-php-fpm Failed to Start Issue

centosphp-fpm

I have two versions of PHP on my CentOS 7 Apache server:

  • 5.6
  • 7.2

It was working but now I'm getting some weird errors that I can't decipher or use to debug.

Doing:

$ sudo service php72-php-fpm restart

showed me this:

Job for php72-php-fpm.service failed because a fatal signal was delivered causing the control process to dump core. See "systemctl status php72-php-fpm.service" and "journalctl -xe" for details.

Running:

$ systemctl status php72-php-fpm.service

Showed:

Hint: Some lines were ellipsized, use -l to show in full.

and

$ journal -xe

Showed nothing to do with the service.

How do I go about debugging and fixing this?

Best Answer

From pasted error, you have installed oci8 extension without having oracle library (version 18.3).

Install the library from Oracle site, and fix LD_LIBRARY_PATH for FPM.

You can either

  • global set linker path (will work all SAPI)

echo /usr/lib/oracle/18.3/client64/lib >>/etc/ld.so.conf.d/oracle.conf

Or

  • Set FPM service environnement (only for FPM)

systemctl edit php72-php-fpm

And add a Environnement directive there

[Service]
Environment=LD_LIBRARY_PATH=/usr/lib/oracle/18.3/client64/lib

If you don't need this extension, simply remove it

yum remove php72-php-oci8

It was working but now I'm getting some weird errors...

If updated from a previous version, build with an older client library version, you need to also update the library.
