A brief introduction to nginx

Nginx is a high-performance HTTP and reverse proxy server written by Russians. in the case of high connection concurrency, it can support responses of up to 50000 concurrent connections, but the consumption of memory, CPU and other system resources is very low, and the operation is very stable. At present, Nginx is used in many large domestic enterprises. According to the latest statistics, the market share of Nginx has reached about 33%. Although the market share of Apache is still the highest, it shows a downward trend. And the momentum of Nginx is clear. The reason for choosing Nginx is also simple: first, it can support 5W high concurrent connections; second, it consumes less memory; third, it has a low cost, and hundreds of thousands more are needed if F5, NetScaler and other hardware load balancing devices are used. Nginx is open source, can be used for free and can be used for commercial purposes.

Second, forward agency

(server located between the client and the original server (origin server)) in order to get content from the original server (the client has difficulty requesting by itself), the client sends a request to the agent and specifies the target (the original server), and then the agent transfers the request to the original server and returns the obtained content to the client

III. Reverse agency

It means that the proxy server accepts the connection request on the internet, then forwards the request to the server on the internal network, and returns the result obtained from the server to the client requesting the connection on the internet. At this time, the proxy server behaves as a reverse proxy server.
