what is nginx

Nginx (engine x) is a high-performance HTTP and reverse proxy web server, and also provides IMAP/POP3/SMTP services. In the case of high concurrency of connections, Nginx is a good alternative to Apache service.

Nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server, released under the BSD-like protocol. Its characteristics are that it occupies less memory and has strong concurrency capabilities. In fact, nginx’s concurrency capabilities do perform better among web servers of the same type. Users of nginx websites in mainland China include: Baidu, JD.com, Sina, NetEase, Tencent, Taobao, etc.

Nginx can be compiled and run on most UnixLinux OS, and there is a Windows ported version. The 1.4.0 stable version of Nginx was released on April 24, 2013. Under normal circumstances, for new sites, it is recommended to use the latest stable version as the production version. There is not a high urgency to upgrade existing sites. Nginx's source code uses a 2-clause BSD-like license.
