Install Fresh install, memcache errored out

memcached server is not same as memcached PHP extension or memcache PHP extension - all 3 are separate installable items.

memcache PHP extension is ancient and really isn't used anymore but Centmin Mod 123.09beta01 did update the routine to install memcache branch with PHP 8 support. Seems that is the part that failed.

would need the full initial install log to troubleshoot and you may need to do a fresh install on fresh CentOS install after troubleshooting.

Troubleshooting Initial Install

To troubleshoot initial installation, you need to check the initial install log at /root/centminlogs and instructions under Sharing logs and errors heading for using Pastebin.com or Gists to share a sanitised version of the contents of the initial install log. You can see full details at How to troubleshoot Centmin Mod initial install issues

Example for 123.09beta01 and newer list /root/centminlogs files in date ascending order and grep for installer_*

Code (Text):

ls -lahrt /root/centminlogs | grep installer_*

example output returns install log at /root/centminlogs both a the full log and minimal log (smaller in size with some stuff filtered out)

Code (Text):

ls -lahrt /root/centminlogs | grep installer_*
-rw-r--r-- 1 root root 4.3M Jul 12 09:06 installer_120718-083445.log
-rw-r--r-- 1 root root 826K Jul 12 10:20 installer_120718-083445_minimal.log

Example for 123.08stable list /root/centminlogs files in date ascending order and grep for install.log

Code (Text):

ls -lahrt /root/centminlogs | grep install.log

example output returns install log at /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

Code (Text):

ls -lahrt /root/centminlogs | grep install.log
-rw-r--r--  1 root root 2.2M Oct 11 01:40 centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

in SSH use cat to ouput contents of /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log. Clear your SSH client window/buffer so only output is the contents of the file

for 123.08stable

Code (Text):

cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

for 123.09beta01 and newer

Code (Text):

cat /root/centminlogs/installer_120718-083445_minimal.log

Then copy and paste into Pastebin.com or Gists entry. If your SSH window scroll buffer isn't that large to get the whole contents of the install log, you can download file manually and copy and paste contents. But makes sure it's sanitised version of the contents of the initial install log as outlined at How to troubleshoot Centmin Mod initial install issues

 

Ok found the bug, not that bad as it's just a PHP 8 routine bug when setting up Memcached server's admin statistics page at /usr/local/nginx/html/memcache_***.php where *** is randomly generated so it would be accessed at your main hostname domain.com/memcache_***.php the routine also password protects the file with user/pass within the PHP file itself. The routine you see the error is for that setup for the memcache_***.php file and not related to actual functioning of Memcached server or memcache or Memcached PHP extensions.

I've updated Centmin Mod 123.09beta01 with a fix so that fresh installs which default to PHP 8, pickup the correct directory for PHP-8's memcache-8 directory which contains the source memcache.php file that is processed.
