Optimize Images for Faster Loading - Ubuntu

Optimize Images for Faster Loading - Ubuntu
To optimize all the images in the public_html folder once a month. Run this:

Code:
apt-get install jpegoptim optipng

Code:
nano /etc/cron.monthly/optimgs

Code:
#!/bin/bash
cd /var/sentora/hostdata/zadmin/public_html
find -iregex '.*\.\(png\)$' -print0 | xargs -0 optipng -o7 -preserve
find -iregex '.*\.\(jpg\|jpeg\)$' -print0 | xargs -0 jpegoptim --max=90 --strip-all –all-progressive --preserve --totals
find -iregex '.*\.\(jpg\|png\|jpeg\)$' -exec chmod 644 {} \;
find -iregex '.*\.\(jpg\|png\|jpeg\)$' -exec chown www-data:www-data {} \;
exit 0

F3 will save the file and Ctrl+X will exit nano.

Code:
sudo chmod +x '/etc/cron.monthly/optimgs'
sudo chmod 755 '/etc/cron.monthly/optimgs'

A bit of a warning. OptiPNG is very slow. May take a few hours to complete if you have a large amount of .pngs

This cron will use a lot of CPU so better if you downgrade priority using NICE

This is for Sentora.

It's just a cron job. You can create a cron job to run when ever you like.

Been running this for awhile now. It really doesn't use that much CPU. Did a load test to see how much it effected the server, and it doesn't slow down the site at all.
