Nginx is one of the fastest server for web. So installing it in your mac is not so difficult. I am describing here about how to Install Nginx mac brew

First you may need to stop the apache, that already running in your system. For stop apache

sudo apachectl stop
sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

Run the below command to install nginx

brew install nginx

Then you can see the nginx in the browser with http://localhost:8080

For stopping nginx run

sudo nginx -s stop

For start nginx run

sudo nginx

To make a proxy in nginx. Go to the servers directory

cd /usr/local/nginx/servers

then create a server name example-proxy.conf with below configuration.

server {
    listen 80;
    location / {
        proxy_pass http://192.x.x.2;
    }
}
