Install Nginx service and nginx Service

Install Nginx service and nginx Service

Nginx features:

Static small files (1 MB), supporting high concurrency, and consuming little system resources. 3 W concurrency, 10 processes, memory 150 M.

Nginx features:

1. simple configuration, flexible and lightweight.

2. High concurrency (static small files) and tens of thousands of static concurrency.

3. Few resources are occupied. Concurrent activation of 10 thread services, with memory consumption of several hundred MB.

4. There are many functional categories (Web, cache, proxy), and each function is not particularly powerful.

5. Supports the epoll model so that Nginx can support high concurrency! Apache (select model ).

6. Nginx can be used with dynamic services (FASTCGI Interface)

7. Using nginx, you can speed up IP addresses and limit the number of connections.

1.1 Nginx Installation

1.1.1 create an Nginx virtual user

 

-1 [root @ Web-lnmp02 ~] # Useradd nginx-s/sbin/nologin-M # prohibit users from logging on to ssh without creating a home directory 2 [root @ Web-lnmp02 ~] # Id nginx3 uid = 501 (nginx) gid = 501 (nginx) groups = 501 (nginx) 4 [root @ Web-lnmp02 ~] #
