Nginx Load Balancer Reverse Proxy

A (master), B, C server, a primary server

Principle:

Domain name resolves to a server, a server is assigned to B, C server

Core configuration (The configuration method master does not provide services):

Upstream nginx.cn {

#ip_hash;

#server 192.168.1.228:80 weight=5;

#server 192.168.1.224:80 weight=5;

Server 192.168.1.228:80;

Server 192.168.1.240:80;

}

server{

Listen 80;

server_name nginx.cn;

Location/{

Proxy_pass http://nginx.cn;

if ($request _uri ~* ". *\. ( JS|CSS|GIF|JPG|JPEG|PNG|BMP|SWF) ($ ") {

Proxy_pass http://nginx.cn;

}

}

location/status{

Auth_basic "Nginxstatus";

Stub_status on;

Access_log on;

}

}

If the IP of the primary server is put into the upstream, the server will assign itself to load tasks, unlimited self-mobilization, will cause a dead loop.

because:Port 80 has been used to monitor the processing of load balancing, then the server can no longer use the 80 port to process access requests, you have to use a new. So we add the nginx.conf of the main server to the following code:

server{
Listen 8080;
server_name a.com;
Index index.html;
root/data0/htdocs/www;
}

All configurations (The configuration method master server does not provide services):

User www www;

Worker_processes 10;

PID Nginx.pid;

events{

Use Epoll;

Worker_connections 51200;

}

HTTP {

Include Mime.types;

Default_type Application/octet-stream;

Keepalive_timeout 120;

Tcp_nodelay on;

Upstream nginx.cn {

#ip_hash;

#server 192.168.1.228:80 weight=5;

#server 192.168.1.224:80 weight=5;

Server 192.168.1.228:80;

Server 192.168.1.240:80;

}

server{

Listen 80;

server_name nginx.cn;

Location/{

Proxy_pass http://nginx.cn;

if ($request _uri ~* ". *\. ( JS|CSS|GIF|JPG|JPEG|PNG|BMP|SWF) ($ ") {

Proxy_pass http://nginx.cn;

}

}

location/status{

Auth_basic "Nginxstatus";

Stub_status on;

Access_log on;

}

}

}

Other webserver only need to configure the appropriate domain name to
