Optimize Images for Faster Loading - Ubuntu

[pinguy]

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 just for zadmin?

also is there a method to manually start or say on a specific time and date?

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.
