Advertisements

Gzip is a software application, has .gz file format used on Unix and Unix-like systems to compress HTTP content including images, medias, javascript, css files before it’s served to a client or browser. Here we will enable Nginx Gzip Compression.

Open Nginx configuration file

sudo nano /etc/nginx/nginx.conf

Edit Nginx Configuration file

sudo vi /etc/nginx/nginx.conf

Enable Nginx Gzip compression

Uncomment the below code in nginx.conf, if this code is not available in file then paste this code in nginx.conf.

#gzip on;

         #gzip_vary on;
         #gzip_proxied any;
         #gzip_comp_level 6;
         #gzip_buffers 16 8k;
         #gzip_http_version 1.1;
         #gzip_types text/plain text/css application/json application/javascript$

Now, press CTRL + X and then press Y button.

Now, Gzip is enabled and we need to restart the nginx. Use below commands to restart the nginx.
