本文详细介绍了如何在Nginx中启用Gzip压缩功能，通过调整配置文件实现节省带宽并显著提高网页加载速度。通过简单的编辑nginx.conf文件并重启服务，即可激活Gzip压缩，测试方法也一并给出。

Enabling Gzip compression in Nginx is very easy, and allow us to save bandwidth transfer and also almost duplicate/triplicate our page speed. First step is edit nginx.conf file, that could be located somewhere /etc/nginx/nginx.conf or /usr/local/nginx/conf/nginx.conf, in most distributions.

Once there, you just need to add this code to the http section, like this:

http {
...
...
...
# enable gzip compression
gzip on;
gzip_min_length  1100;
gzip_buffers  4 32k;
gzip_types    text/plain application/x-javascript text/xml text/css;
gzip_vary on;
# end gzip configuration
...
...
...
}

Once you finish editing the file, just restart nginx:

/etc/init.d/nginx restart
