**一、Nginx简介**

Nginx是一个高性能的HTTP和反向代理服务，也是一个IMAP/POP3/SMTP服务，也可以用来做负载均衡，目前使用最多的就是负载均衡，具体简介自行百度咯

**二、Nginx安装**

Linux系统是64位的Centos 6.5 ，默认用root用户下安装，也可自行切换用户组安装

**1、下载Nginx及相关组件**

下载地址：[http://nginx.org/download/][http_nginx.org_download]  下载需要安装的版本，本文使用的是1.14.2版本

或者使用 wget方式下载：

[root@localhost src]# wget http://nginx.org/download/nginx-1.14.2.tar.gz

安装gcc，pcre-devel，zlib等依赖，如已安装可略过（也可使用二进制编译方式安装）

[root@host-172-17-110-221 ~]# yum install autoconf automake zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc
    [root@host-172-17-110-221 ~]# yum install pcre-devel

**2、安装Nginx及相关组件**

解压nginx压缩包

[root@host-172-17-110-221 ~]# tar -zxvf nginx-1.14.2.tar.gz

编译

[root@jkzl-hadoop data]# cd nginx-1.14.2
    [root@jkzl-hadoop nginx-1.14.2]# ./configure --prefix=/usr/local/nginx
    安装结果省略。。。
    [root@jkzl-hadoop nginx-1.14.2]# make && make install
    编译结果省略。。。

启动nginx

[root@jkzl-hadoop nginx-1.14.2]# cd /usr/local/nginx/sbin/
    [root@jkzl-hadoop sbin]# ./nginx

验证启动是否成功，打开浏览器输入安装的服务器ip，例如：localhost，看到下图，说明nginx启动成功

**4、Nginx简单配置示例**

修改配置：

[root@jkzl-hadoop nginx]# vi conf/nginx.conf

配置示例：

#user  nobody;
    worker_processes  1;
    
    #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;
    }
    
    
    http {
        include       mime.types;
        default_type  application/octet-stream;
        sendfile        on;
        #tcp_nopush     on;
    
        #keepalive_timeout  0;
        keepalive_timeout  65;
    
        #gzip  on;
    
        server {
            listen       80;
            server_name  localhost;
            location / {
                root   html;
                index  index.html index.htm;
            }
    
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
    
        }
    	
        #1235
        server {
            listen       1235;
            location / {
                proxy_pass http://192.168.1.220:10080;
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
            }
            location /ehr {
                proxy_pass http://192.168.1.221:8090/ehr;
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
            }
    
            location /bigScreenShow {
                alias /usr/local/nginx/app-big-data/;
            }
            location /app-health/ {
                alias /usr/local/nginx/app-health/;
            }
        }
    
    
    
    }

保存配置，重载配置

[root@jkzl-hadoop sbin]# ./nginx -s reload

请求1235端口，查看效果
