Install Install Centmin Success but cant install composer | php

Centmin mod won't work with yum installed php, it has to be source compiled php via centmin.sh. Sounds like the initial centmin mod install on DO failed to properly install php. You can check install log for initial install in /etc/centminlogs for clues as to why php failed to install as per initial install troubleshooting guide below.

You'll need to post on the forums with the following info

• Server or VPS details ? XEN, KVM, OpenVZ, VMWare or dedicated server ? OS ? CentOS 6.7 or 7.2 ? 32bit or 64bit ?
• What version of Centmin Mod ? .07 stable or 08 stable or .09 beta01 or another branch version ?
• Was it fresh install or upgrade ?
• Method of install ? Via centmin.sh menu option 1, Git install or curl one liner install as outlined at centminmod.com/download.html ?
  
• How long ago did you install Centmin Mod ?
• There's numerous code changes, bug fixes over time, so ensure you have latest Centmin Mod code installed by upgrading your Centmin Mod code as instructed below.

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

If it's possible to reload and reinstall clean fresh CentOS image, you can try a fresh install and make sure php is installed and working first.

 

you can't see logs at /root/centminlogs ?

as root use in SSH type

Code (Text):

ls -lAhrt  /root/centminlogs

find the install log and cat output or download file and copy and paste contents to pastebin.com or gist.github.com
example list log files

Code (Text):

ls -lAhrt  /root/centminlogs | grep '_install.log'
-rw-r--r--. 1 root root 2.3M May 20 18:08 centminmod_1.2.3-eva2000.09.001_200516-133248_install.log

cat output

Code (Text):

cat  /root/centminlogs/centminmod_1.2.3-eva2000.09.001_200516-133248_install.log

which you copy and paste or save log locally

 

Yes centmin mod works with both centos 6 and centos 7.

from your install log, both nginx and php-fpm failed to install as seen in post-install check output

nginx failed as you hit a 123.08stable nginx 1.11.2 bug which i just fixed at Centmin Mod 123.08stable update for Nginx 1.11.2 compatibility.

php failed to compile as you ran out of available memory also FYI, PHP 7.0.8 is latest

Code (Text):

virtual memory exhausted: Cannot allocate memory
make: *** [ext/fileinfo/libmagic/apprentice.lo] Error 1

Reason is minimum system requirements for CentOS 7 is 1GB memory as per Raising minimum & recommended disk requirements for Centmin Mod LEMP installs | Centmin Mod Community and download page at centminmod.com/download.html

If you use 512MB VPS, use CentOS 6.x instead

 

similar error which basically means php compile terminated due to low system available memory as fileinfo php module is very memory intensive for compilation and 123.08stable doesn't have same 123.09beta01 auto detection routine. In 123.09beta01 i have coded a system available memory detection routine to check if system memory is available. If not enough memory, it will auto disable just php fileinfo extension. This you can see in 123.09beta01's inc/php_configure.inc lines 141-145 and line 11 defines the low memory threshold as below 530000 bytes

Code (Text):

-c /svr-setup/php-7.0.8/ext/fileinfo/libmagic/apprentice.c -o ext/fileinfo/libmagic/apprentice.lo
gcc: Internal error: Killed (program cc1)
Please submit a full bug report.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
make: *** [ext/fileinfo/libmagic/apprentice.lo] Error 1

I'd recommend you use centmin mod 123.09beta01 instead for now Beta Branch - Centmin Mod .09 beta branch Testing | Centmin Mod Community however seems 123.08stable version also has this routine check centminmod/php_configure.inc at 123.08stable · centminmod/centminmod · GitHub so will need to see why - maybe i need to increase the low memory threshold value

install default php 5.6.x latest

Code (Text):

yum -y update; curl -O https://centminmod.com/betainstaller.sh && chmod 0700 betainstaller.sh && bash betainstaller.sh

install with php 7.0.x latest

Code (Text):

yum -y update; curl -O https://centminmod.com/betainstaller7.sh && chmod 0700 betainstaller7.sh && bash betainstaller7.sh

123.09beta01 change log at Change Log - CentminMod.com LEMP Nginx web stack for CentOS

 

fyi, i updated both 123.08stable and 123.09beta01 and raised the low memory threshold for php fileinfo extension's memory check from 530000 bytes to 780000 bytes so you should be able to install properly now either version as any detected system installed memory below 780000 bytes will auto disable fileinfo extension in php

commits at

• Stable Branch - update inc/php_configure.inc raise low mem threshold for fileinfo disable routine | Centmin Mod Community
• Beta Branch - update inc/php_configure.inc raise low mem threshold for fileinfo disable routine | Centmin Mod Community

Thanks for reporting this issue. You just made centmin mod better

edit: hmm i believe you enabled fileinfo option PHPFINFO='y' in centmin mod as php composer needs it though right ?

what's output of command

Code (Text):

free -m

 

You need to reinstall fresh clean CentOS OS first

Right now PHPFINFO=y gets overrident to =n to disable if system memory is below 780000 bytes threshold ~761MB. So that wouldn't help if you need PHP to install fileinfo php extension for PHP composer usage. But Centmin Mod 123.08stable and 123.09beta01 will cleanly install with the update i made.

So if you need fileinfo php extension for PHP composer, you need a VPS with more than 761MB of memory installed due to higher fileinfo php compilation memory requirements.

So probably if $$$ budget is a concern maybe probably better to get a Linode $10/month VPS which has 2GB memory due to free memory upgrades Linode - Linode’s 13th Birthday – Gifts for All! | Centmin Mod Community

DO vs Linode vs Vultr benchmarks too Virtual Private Server (VPS) hosting | Centmin Mod Community

 

Centmin mod installs fine i have it running on 128-256MB VPS (128MB with variable tweak) but centos 6 32bit OS for that and php fileinfo disabled.

Ah i see why you do not have a swap file set so that limits total memory availability with disk swap being a memory buffer

so do the following if you need php fileinfo extension on 512mb vps

1. fresh centos 6.x latest 64bit if you plan to upgrade the vps later to higher memory plans. If you do not ever plan to do a in-place same vps upgrade vps plans for more memory you can use centos 6.x 32bit as it has lower memory requirements than 64bit
2. create swap file - 2GB swap file via single command below

Code (Text):

echo "create 2GB swap file"; dd if=/dev/zero of=/swapfile bs=1024 count=2048k; ls -lah /swapfile; mkswap /swapfile; swapon /swapfile; chown root:root /swapfile; chmod 0600 /swapfile; swapon -s; echo "/swapfile swap swap defaults 0 0" >> /etc/fstab; mount -a;

3. confirm via free -m command swap file is created
4. then install centmin mod

 

Basically fileinfo php compile via source is memory intensive. Same problem whenever you source compile PHP on any system

i.e.

• cpanel Out of memory error compiling with Fileinfo | cPanel Forums
• PHP :: Bug #48809 :: "virtual memory exhausted: Cannot allocate memory" with libmagic/apprentice.c

might need to add to centmin mod install routine detection for swap file existence

 

FYI, updated centmin mod stable and beta code with auto 1GB swap file creation if swap file isn't detected Install - Centmin Mod 1.2.3-eva2000.08 how to install & update | Page 3 | Centmin Mod Community

 

FYI github has a major outage right now https://twitter.com/githubstatus/status/750759736727969792 so might want to try later

 

Ah yes Vultr 768MB VPS is $5/month too

Thanks for reporting anyway as the code changes I just committed means improved functionality for Centmin Mod

Did a quick check on DigitalOcean 512MB VPS with 0 swap size to see the new auto swap file creation process in action DigitalOcean - 512MB DigitalOcean VPS - Centmin Mod 123.09beta01 Install Test | Centmin Mod Community
