Compiling PHP 7.2.0 + PGO

123.09beta01 was recently updated to only enable PHP_PGO if there's more than 2 cpu threads on server due to extended compilation times for PHP which would be slower with only 1 cpu thread.

 

if server has 2 or more cpu core/threads then setting in /etc/centminmod/custom_config.inc

Code (Text):

PHP_PGO='y'

before (not after) running centmin.sh menu option 5 should compile any PHP 7 version with PGO

End of php compile should have something like

Code (Text):

***************************************************
* PHP upgraded and auto reinstalled PHP extensions
* PHP_PGO='y' detected. PHP compiled with Profile Guided Optimizations
* https://software.intel.com/en-us/blogs/2015/10/09/pgo-let-it-go-php
***************************************************

If it doesn't, to troubleshoot, you need to check the the php upgrade 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

If you type this command it lists all logs in date ascending order so latest log at bottom

Code (Text):

ls -lArt /root/centminlogs

so copy the entire contents of latest nginx_upgrade log to gist.github.com or pastebin.com

you can use grep to filter the logs, i.e. look for nginx_upgrade or php in log name

Code (Text):

ls -lahrt /root/centminlogs/ | egrep 'nginx_upgrade|php_upgrade'

Code (Text):

ls -lahrt /root/centminlogs/ | egrep 'nginx_upgrade|php_upgrade'
-rw-r--r--  1 root root  2.6M Oct  3 03:48 centminmod_1.2.3-eva2000.09.001_031016-034409_php_upgrade.log
-rw-r--r--  1 root root  664K Oct 12 09:24 centminmod_1.2.3-eva2000.09.001_121016-092406_nginx_upgrade.log

So the last php upgrade log was named centminmod_1.2.3-eva2000.09.001_031016-034409_php_upgrade.log and located at /root/centminlogs/centminmod_1.2.3-eva2000.09.001_031016-034409_php_upgrade.log
then use cat command to output the contents of that log. Do the same for any other relevant logs. i.e. if you ran centmin.sh menu option 10, you would have memcached_reinstall.log log too

clear your ssh window buffer/screen and type

Code (Text):

cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_031016-034409_php_upgrade.log

then select and copy and paste output to pastebin.com or gist.github.com file to share. If your SSH client's scroll buffer isn't large enough using cat might not output the entire log file contents, so you may need to download the log and use local text editor to open and copy and paste.

so only need content of 1 specific log, in this case most recent php_upgrade.log logs

 

Also verify you have more than 2 cpu core/threads with command

Code (Text):

grep -c "processor" /proc/cpuinfo

should report number of cpu cores
