nginx+tomcat 实现反向代理配置

一段简单的实现反向代理的代码 -要将请求传递给HTTP代理服务器，则在一个location块内指定proxy_pass指令

server {          listen       80;                                                                server_name  localhost;                                                      client_max_body_size 1024M;        location / {            proxy_pass http://localhost:8080;            proxy_set_header Host $host:$server_port;        }}

保存配置文件后启动Nginx，这样当我们访问localhost的时候，就相当于访问 localhost:8080 了。

注意如果代理访问url地址为http://localhost:8080/jenkins

 location ^~ /jenkins/ {            proxy_pass   http://localhost:8080/jenkins;            proxy_set_header Host $host:$server_port;        }

或输入地址端口即访问

 location / {            proxy_pass   http://localhost:8080/jenkins;            proxy_set_header Host $host:$server_port;        }

Nginx 其他命令
以下包含了 Nginx 常用的几个命令：
/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx

在nginx–>conf 目录下：
1.新建proxy.conf 文件

#!nginx (-)# proxy.conf proxy_redirect          off;proxy_set_header        Host $host;proxy_set_header        X-Real-IP $remote_addr;  #获取真实ip#proxy_set_header       X-Forwarded-For   $proxy_add_x_forwarded_for; #获取代理者的真实ipclient_max_body_size    10m;client_body_buffer_size 128k;proxy_connect_timeout   90;proxy_send_timeout      90;proxy_read_timeout      90;proxy_buffer_size       4k;proxy_buffers           4 32k;proxy_busy_buffers_size 64k;proxy_temp_file_write_size 64k;

2.修改nginx.conf,完整内容如下
