PHP-FPM Upgraded to PHP 7 and memcached.so throwing errors

Centmin Mod Github master branch is 123.08stable and that doesn't support PHP 7 memcache/memcached PHP extensions fully. Only Centmin Mod 123.09beta01 branch specifically supports PHP 7 for those extensions as the memcache/memcached PHP extensions are sourced from beta/experimental branches of their respective github repos still.

Also 123.09beta01 has quite a few changes to support gitlab fall back mirrors for github past few days Commits · centminmod/centminmod · GitHub But haven't touched memcache/memcached PHP extensions yet for fallback. The end goal is to have Centmin Mod 123.09beta01 fully working with gitlab repo mirror fallback from github Install Centmin Mod LEMP stack via Gitlab.com Mirror | Centmin Mod Community

 

FYI newrelic announced official PHP 7 support with their latest newrelic-php agent unfortunately it causes segfaults heh PHP-FPM - newrelic-php extension causing segfault errors in PHP-FPM | Centmin Mod Community so nearly there.

As to memcache and php 7 never worked on 123.08stable/master branch as the sourced memcache git repo doesn't support php 7. I had to use a separate github repo for memcache php 7 support at GitHub - websupport-sk/pecl-memcache (gitlab mirror at centminmod-github-mirror / pecl-memcache · GitLab

However, looks like memcache + php 7 is broken now too on 123.09beta01 - it's actually a bug in 123.09beta01 which i have just committed the fix for

Looks like i did port memcached php 7 extension support to 123.08stable from the code at centminmod/memcached_install.inc at 123.08stable · centminmod/centminmod · GitHub

FYI, inc/memcached_install.inc history of changes from 123.09beta01 to 123.08stable at History for inc/memcached_install.inc - centminmod/centminmod · GitHub

 

To troubleshoot, you need to check the the centmin.sh menu option 10 reinstall memcached log at /root/centminlogs can post a copy to Pastebin.com or Gists to share. Every centmin.sh menu option automatically saves a detailed log at /root/centminlogs
i.e.

Code (Text):

ls -lahrt /root/centminlogs/ | grep memcached
-rw-r--r--   1 root root  229K Mar 12 07:07 centminmod_1.2.3-eva2000.09.001_120316-070622_memcached_reinstall.log
-rw-r--r--   1 root root  119K Mar 12 07:17 centminmod_1.2.3-eva2000.09.001_120316-071611_memcached_reinstall.log

 

for 123.08stable memcache + php 7 never worked so what you see in log is normal = failed memcache compile on php 7. You need 123.09beta01 for memcache + php 7 to work.

I've backported igbinary and memcache php 7 extension support to 123.08stable for now Stable Branch - back port igbinary & memcache php extension PHP 7 support 123.08stable | Centmin Mod Community

for memcached.h what's the output for the commands below ?

Code (Text):

yum -q whatprovides */memcached.h --enablerepo=remi --disableplugin=priorities

Code (Text):

yum -q whatprovides */memcached.h --disableplugin=priorities

 

Remi is installed by default but disabled by default unless you use --enablerepo=remi when needed or when centmin.sh code installs yum packages like libmemcached and imagemagick from remi repo

probably easiest way is switch to 123.09beta01 branch as that is what's going to be stable soon

just install remi repo.. in 123.09beta01 when you run centmin.sh menu option 15 to recompile imagick php extension, it auto detects if remi repo is installed and if missing, installs remi repo and sets it up

 

Or you can dig into centmin mod 123.09beta01 inc/imagick_install.inc code for the remi repo install commands to run manually centminmod/imagick_install.inc at 123.09beta01 · centminmod/centminmod · GitHub

specific lines at centminmod/imagick_install.inc at 123.09beta01 · centminmod/centminmod · GitHub refer to functions in

centminmod/downloads_centossix.inc at 123.09beta01 · centminmod/centminmod · GitHub

centos 7

associated yum priorities function for remi repo centminmod/yumpriorities.inc at 123.09beta01 · centminmod/centminmod · GitHub

referenced .rpm install file urls are all in inc/downloadlinks.inc centminmod/downloadlinks.inc at 123.09beta01 · centminmod/centminmod · GitHub

or easy way is switch to 123.09beta01 and when you run centmin.sh menu option 15 - it auto does all the remi repo install and yum priorities set for you
