最近在调试 wordpress 的时候用faster cache 的插件，里面需要开启Gzip模块

On servers using Nginx, gzip compression cannot be activated automatically, so you have to enable gzip compression manually.

You need to add the following code into the /etc/nginx/nginx.conf to enable gzip in Nginx servers. Do not add anywhere. You should add it inside the http {} section.

gzip on;
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types image/svg+xml text/plain text/html text/xml text/css text/javascript application/xml application/xhtml+xml application/rss+xml application/javascript application/x-javascript application/x-font-ttf application/vnd.ms-fontobject font/opentype font/ttf font/eot font/otf;

nginx -t 的时候会报错
duplicate MIME type "text/html" in nginx.conf
原因其实非常简单，只要你开启了gzip的模块，那么text/html就被默认的开启了。所以需要手动的去把上面的配置文件里面里面的 text/html去掉。

gzip on;
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types image/svg+xml text/plain text/xml text/css text/javascript application/xml application/xhtml+xml application/rss+xml application/javascript application/x-javascript application/x-font-ttf application/vnd.ms-fontobject font/opentype font/ttf font/eot font/otf;
