nginx反向代理的设置

在此之前都是将nginx作为web服务器，

现在准备将nginx作为反向代理服务器，

user root;
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 {
use epoll;
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;
#有几台服务器就添加几个server
server
{
listen 80; #客户端访问反向代理服务器监听的端口
server_name dss1; #客户端访问反向代理服务器，需要一个域名，这个域名就是  反向代理服务器要访问谁的意思，所以我设置完后访问的依然只是dss1，访问不到dss2，因为dss1在前面， 它只访问前面的

　　　　　　　　  #我把dss2放在前面 他就只访问dss2不访问dss1，所以下面就要做一个负载均衡

#charset koi8-r;

#access_log logs/host.access.log main;

location /
{
#反向代理服务器转发指令
proxy_pass http://dss1.com;
}

}

}
#上面时设置了转发指令，转发给了dss1.com,那么dss1是谁，现在就是要对dss1做一个代理
upstream dss1.com
{
server 192.168.2.32:80;
}

 

server
{
listen 80;
server_name dss2;
location /
{
proxy_pass http://dss2.com;
}
}

upstream dss2.com
{
server 192.168.2.33:80;
}

 

 

}
