Nginx 反向代理，负载均衡，动静分离配置

2017-06-23 15:28 731 查看
上篇介绍了Nginx的安装，本片博客介绍nginx的配置文件

代理服务器：172.16.101.57

服务器1：172.16.101.26

服务器2 : 172.16.101.27



服务器1,和服务器2分别在tomcat上部署一个简单的web程序TestNginx，只是为了测试负载，反向代理，和动静分离。

index.jsp

<title>index.jsp</title>
</head>
<body>
你好，请求服务器成功<br>
<a href="./home.jsp">home.sjp</a>
</body>
</html>


贴出nginx的配置文件

反向代理和负载均衡

通过以下配置实现反向代理和负载均衡,可以看到请求了代理服务器（172.16.101.57)的地址，将服务器1/服务器2的index.jsp返回给客户浏览器

upstream localhost {
server  172.16.101.26:8080;
server  172.16.101.27:8081;
}

location /TestNginx {
proxy_pass   http://localhost/TestNginx; proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
proxy_ignore_client_abort on;

client_max_body_size    10m;
client_body_buffer_size 128k;
}




接下来通过刷新4次浏览器，查看日志 access.log，确认具体请求是哪台服务器。



两台服务器分别交替请求

动静分离

静态的文件如图片和html,css，js等是不需要放在服务器上去请求，只需要放在代理服务器上

location ~ \.(gif|jpg|png)$ {
root data/images;
}




查看access.log日志是没有发送到服务器1或服务器2
