Nginx is a performance-oriented HTTP server, which has the advantages of less memory and high stability compared with Apache and lighttpd.

An introduction to Nginx 1.1Nginx features

Modular design, good expansibility

High reliability

Support for hot deployment: update configuration files, upgrade versions, and replace log files without downtime

Low memory consumption: 10000 inactive connections in keep-alive connection mode, requiring only 2.5m memory event-driven,aio,mmap,sendfile

2. Nginx service architecture master/worker structure

Master process: responsible for loading and analyzing configuration files, managing worker processes, and smoothly upgrading

Worker process: receive client request, send the request to each module at once, filter, call Imax O, cache data, send response

Cache related processes: cache loader (cache index reconstruction) and cache manager (cache index management)

-Cache loader is generated by the main process after the Nginx service starts, and then exits after the index Metabase is established according to the cache on the local disk.

-Cache manager determines whether the metadata is out of date after the metadata update is completed.

III. Components of the configuration file structure of Nginx

Master profile: nginx.conf

Subprofile: include conf.d/*.conf

Fastcgi, uwsgi, scgi: and other protocol-related configuration files. Under the root path

Mime.types: supported mime types. Under the root path
