Compiling PHP on fresh install fails

digij · May 23, 2018

CentOS Version: CentOS 7 64bit
Centmin Mod Version Installed: 123.09beta01
Nginx Version Installed: 1.13.12
PHP Version Installed: 5.6.36

Compiling PHP fails (see output below)

I have Centmin running on a few more KVM-VPS following the same procedure and never ran in such a problem. The only thing that sets the VPS I'm installing on apart is the rather old CPU...

Code:

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 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
Code (Text):
cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.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

Thanks a lot for looking into this!

eva2000 · May 23, 2018

gist is 404 not found for me

I have realised... My account has been flagged right after uploading

I guess the logfile must have triggered an algorithm...

Do you mind sharing the file on e.g. OneDrive?

eva2000 · May 23, 2018

try using pastebin.com

digij · May 23, 2018

No premium account and file-size approx. 4 mb...

Let's see how they quick they are unflagging my GitHub account...

Sorry for 'administrative trouble'

I will post again when the file is ready.

Pastebin has a sale running so I haven't been able to resist

eva2000 · May 23, 2018

looks like it's due to probably bios settings or your web host kvm configuration not passing all the supported cpu flags i.e. avx is missing

googled for E5-2690v1 cpuinfo example and found

even my same family OpenVZ VPS with E5-2670v1 cpu has avx enabled

I will have to add a check for avx flag into 123.09beta01 but the problem really is your KVM or server config/bios not having enabled AVX

eva2000 · May 23, 2018

updated 123.09beta01 with php check for avx cpu flag Beta Branch - update inc/php_configure.inc double check avx cpu flag exists so try a fresh install and see

ideally your web host's KVM config should pass all cpu supported flags including avx otherwise you will have reduced PHP and general system performance !

digij · May 23, 2018

Fresh install successful

Many thanks!

I have more KVMs from this provider (also on other host nodes - but so far no Centmin install attempts). After a curious check - none of them is exposing AVX to the guest system.

Let's see what they say ref. CPU flags - I opened a ticket.

eva2000 · May 23, 2018

Great to hear. Yes hopefully your web host fixes up their KVM configs
