How to install nginx in centos7

Install the required environment

1. gcc installation

To install nginx, you need to compile the source code downloaded from the official website. The compilation depends on the gcc environment. If you don’t have the gcc environment, you need to install it:

yum install gcc-c++

2. PCRE pcre-devel installation

PCRE (Perl Compatible Regular Expressions) is a Perl library that includes a Perl compatible regular expression library. The http module of nginx uses pcre to parse regular expressions, so the pcre library needs to be installed on Linux. pcre-devel is a secondary development library developed using pcre. nginx also requires this library. Order:

yum install -y pcre pcre-devel

3. zlib installation

The zlib library provides many compression and decompression methods. Nginx uses zlib to gzip the contents of the http package, so the zlib library needs to be installed on Centos.

yum install -y zlib zlib-devel

4. OpenSSL Installation

OpenSSL is a powerful secure socket layer cryptographic library that includes major cryptographic algorithms, commonly used key and certificate packaging management functions, and SSL protocols, and provides a wealth of applications for testing or other purposes. Nginx not only supports the http protocol, but also supports https (that is, transmitting http over the ssl protocol), so you need to install the OpenSSL library on Centos.

yum install -y openssl openssl-devel
