nginx代理配置

1、下载nginx
 rpm包:http://nginx.org/packages/centos/5/x86_64/RPMS/nginx-1.6.3-1.el5.ngx.x86_64.rpm
 源码包:http://nginx.org/download/nginx-1.6.3.tar.gz
 
2、安装nginx
rpm -ivh nginx-1.6.3-1.el5.ngx.x86_64.rpm
编译安装:
#./configure -without-http_rewrite_module
#make
#make install


3、修改nginx配置参数

#vi /etc/nginx/nginx.conf
rpm安装的配置文件

#vi /usr/local/nginx/conf/nginx.conf
源码安装的配置文件

       定义后端主机组
       server 195.203.xx.xx:7001;
       server 195.203.xx.xx:7001;

       //开启长连接，8为连接数

        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {

            proxy_pass   http://test.net;
            //读取分发组
            proxy_http_version 1.1;
            //http1.1支持长连接
            proxy_set_header host $remote_addr;
            proxy_set_header Connection "";
            //开启客户端IP转发
        }

       location /nginx-status {

             auth_basic              "NginxStatus";

         #    allow 192.168.2.0/24;

         #    deny all;

             stub_status on;

             access_log  on;

#             auth_basic_user_file    /usr/local/nginx/conf/htpasswd;

        }
    }
}

4、重启nginx
# service nginx restart
rpm安装重启方式

#/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
源码安装重启方式

5、测试
#netstat -na | grep 7001
在后端服务器上执行，查看长连接状态及连接数
