Nginx是一個高性能的HTTP和反向代理服務器，也是一個IMAP/POP3/SMTP代理服務器。Nginx是由Igor Sysoev爲俄羅斯訪問量第二的Rambler.ru站點開發的。
1、下載
從官網http://nginx.org/en/download.html下載
2、安裝（linux下）
將下載的tar包拷貝至服務器，tar -zvxf nginx-1.17.8.tar.gz 解壓
安裝pcre 以及pcre-devel
yum install pcre pcre-devel
安裝zlib zlib-devel
yum install -y zlib zlib-devel
cd nginx-1.17.8
./configure --prefix=/usr/local/nginx
上面如果提示缺少其他依賴，請安裝並重新運行configure
make && make install
test -f '/usr/local/nginx/conf/fastcgi.conf' \
|| cp conf/fastcgi.conf '/usr/local/nginx/conf'
cp conf/fastcgi.conf '/usr/local/nginx/conf/fastcgi.conf.default'
test -f '/usr/local/nginx/conf/uwsgi_params' \
|| cp conf/uwsgi_params '/usr/local/nginx/conf'
cp conf/uwsgi_params \
'/usr/local/nginx/conf/uwsgi_params.default'
test -f '/usr/local/nginx/conf/scgi_params' \
|| cp conf/scgi_params '/usr/local/nginx/conf'
cp conf/scgi_params \
'/usr/local/nginx/conf/scgi_params.default'
test -f '/usr/local/nginx/conf/nginx.conf' \
|| cp conf/nginx.conf '/usr/local/nginx/conf/nginx.conf'
cp conf/nginx.conf '/usr/local/nginx/conf/nginx.conf.default'
test -d '/usr/local/nginx/logs' \
|| mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/logs' \
|| mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/html' \
|| cp -R html '/usr/local/nginx'
test -d '/usr/local/nginx/logs' \
|| mkdir -p '/usr/local/nginx/logs'
make[1]: 離開目錄“/root/nginx/nginx-1.17.8”
3、啓動
cd /usr/local/nginx
幾個文件夾的內容爲:
conf:配置文件
html:網頁文件
logs:日誌文件
sbin:主要二進制程序
啓動：
./sbin/nginx
[root@localhost nginx]# curl localhost:80
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {
width: 35em;
margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>

4、其他安裝方式
其實可以直接用yum install nginx就好了
5、Nginx配置文件介紹
配置文件/usr/local/nginx.conf:
#user nobody;
worker_processes 1; //工作進程數，可以修改，一般修改爲CPU數目*核數
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;// nginx連接特性，一個進程能夠允許多少個連接數
}
http {//HTTP服務配置
include mime.types;
default_type application/octet-stream;
