DigitalOcean Benchmarks 512MB DigitalOcean VPS - Centmin Mod 123.09beta01 Install Test

Updated Centmin Mod code to auto create a 1GB swap file on disk for non-openvz systems if no swap file is detected. DigitalOcean VPS do not setup a swap file for you unless you setup one for yourself.

On low memory <1GB ram VPS servers, php compile of PHP fileinfo extension will fail as it requires >1GB of memory. However, if you need PHP fileinfo extension enabled (it's disabled by default via PHPFINFO='n' variable in centmin.sh) and have a VPS with <1GB of memory, you run into problems with failed PHP compiles.

Centmin Mod now has added auto creation of a 1GB swap file which can supplement system memory to work around PHP fileinfo extensions memory requirements. It will be slower to compile PHP especially if swap on disk is on a disk with slow disk I/O performance. If your VPS has SSD disks, it would be better.

Centmin Mod Install

SSH commands to install Centmin Mod 123.09beta01 via the curl installer one liner but setup persistent /etc/centminmod/custom_config.inc before install to enable PHPFINFO='y' as it's disabled by default

Code (Text):

mkdir /etc/centminmod
touch /etc/centminmod/custom_config.inc
echo "PHPFINFO='y'" >> /etc/centminmod/custom_config.inc
yum -y update; curl -O https://centminmod.com/betainstaller.sh && chmod 0700 betainstaller.sh && bash betainstaller.sh

Centmin Mod After Install

centmin mod installed successfully but slower due to php compile time needing to hit disk swap due to php fileinfo extension being enabled

Memory Usage

before centmin mod install fresh DO 512MB VPS has no swap file setup

Code (Text):

free -m
             total       used       free     shared    buffers     cached
Mem:           490        120        369          0          6         68
-/+ buffers/cache:         45        444
Swap:            0          0          0

after centmin mod install with swap auto created

Code (Text):

free -m
             total       used       free     shared    buffers     cached
Mem:           490        313        177         11         63        100

Swap:         1023          4       1019

and this is memory and swap usage during php compile with PHPFINFO='y' enabled to enable fileinfo PHP extension support - yup 511MB of memory swap to disk required and 400MB system memory used = ~911MB of memory total.

Code (Text):

 free -ml

             total       used       free     shared    buffers     cached

checking php fileinfo was compiled

Code (Text):

php --ri fileinfo

fileinfo

fileinfo support => enabled
version => 1.0.5
libmagic => 517

Most common is if your web app requires/states fileinfo as a requirement. See PHP: Introduction - Manual
