Enable Nginx Compression and compress js and images :)

[IRJ]

Enable Nginx Compression

sudo nano /etc/nginx/nginx.conf

Uncomment the Following lines. If you have extra CPU on your host, you can turn up the compression level up level 9. I am running level 8 on my server.

Install yui-compressor

sudo apt install yui-compressor

Create Script to run using jar file.

sudo nano /var/www/html/compress_js.sh

Paste the following contents in the file. This will search for javascript files in your /var/www/html directory. Then run the command yui-compressor --type js -o against your javascript files.

#!/bin/sh
for file in `find . -name "*.js"`
do
echo "Compressing $file …"
yui-compressor --type js -o $file $file
done

Now run the script

sudo sh /var/www/html/compress_js.sh

You should see the following output:

Install JPEG Optim

sudo apt install jpegotptim

Create JPEG Optim Script file

sudo nano /var/www/html/compress_jpg.sh

Put the following contents in the file. This script is pretty much the same as our other script. We are searching for all jpg files then running compression on them .

#!/bin/sh
for file in `find . -name "*.jpg"`
do
echo "Compressing $file …"
jpegoptim $file
done

Now run the script

sudo sh /var/www/html/compress_jpg.sh

It should look like this. Also, not that jpegoptim will skip any files that would be made larger by "compression." You can see this when the percentage is notated by a negative percentage. The files are skipped in that case.
