nginx noun meaning explanation

Forward proxy

The forward proxy is the client. The client wants to access a website, but cannot access it. It can access the network through the proxy server. The forward proxy is built between the client and the target host.

Reverse proxy

The reverse proxy is the server. The client sends a request to the reverse proxy server. After the reverse proxy server selects the target server to obtain the data, it returns to the client. At this time, the reverse proxy server and the target server are for the client It is a server that exposes the reverse proxy server address and hides the ip address of the real server.

Load balancing

There are multiple requests in the same time period, and the reverse proxy server distributes these requests evenly to different target servers, thereby sharing the pressure of the server.

Dynamic and static separation

In order to speed up the analysis speed of the website, the dynamic pages and static pages of the website are analyzed by different servers to speed up the analysis speed and reduce the pressure of the original single server. Specifically, when the client accesses a js file or css file, the nginx server will go directly to the static server to get the data, and if it accesses the php data, it will go to the dynamic server to get the data.
