Learning Nginx (I.)

First, why is Nginx

High Concurrency: Support for event ports on Linux Epoll,solaris and Kqueue on FreeBSD. A single machine supports more than 10w of concurrent connections.

Modularity: High scalability, composed of a number of different functions, different levels, different types, low coupling module.

Low memory consumption: 10,000 non-active HTTP keep-alive connections only shui DUI Shang 2.5MB of memory.

Thermal deployment: Master and worker worker process separation design, support for hot deployment, 7x24 hours uninterrupted service. Second, build nginx environment 2.1 Operating system support
