二、搭建 Nginx 环境

1. 安装 nginx

两种方式：

源代码安装：需要编译./configure——> make——>make install
在线安装，参考：http://nginx.org/en/linux_packages.html

在线安装 (这里以 Ubuntu 为例子)：

Install the prerequisites:

BASH

sudo apt install curl gnupg2 ca-certificates lsb-release

To set up the apt repository for stable nginx packages, run the following command:

BASH

echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \| sudo tee /etc/apt/sources.list.d/nginx.list

If you would like to use mainline nginx packages, run the following command instead:

BASH

echo "deb http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \| sudo tee /etc/apt/sources.list.d/nginx.list

Next, import an official nginx signing key so apt could verify the packages authenticity:

BASH

curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add -

Verify that you now have the proper key:

BASH

sudo apt-key fingerprint ABF5BD827BD9BF62

The output should contain the full fingerprint 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62 as follows:

BASH

pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]573B FD6B 3D8F BC64 1079  A6AB ABF5 BD82 7BD9 BF62
uid   [ unknown] nginx signing key <signing-key@nginx.com>

To install nginx, run the following commands:

BASH
