5.修改Nginx配置文件nginx.conf，该文件位于Nginx根目录下的/conf下面。

①在#gzip 

on;

后面加入下面配置:

upstreambackend{

serverlocalhost:

8080;

8088;

ip_hash;

}

其中serverlocalhost:

8080为第一个Tomcat的启动地址，serverlocalhost:

8088为第二个Tomcat的启动地址，ip_hash用于做session同步。

②修改第一个server{}配置中的listen 

80;

改为新的端口号，因为我的本机80端口被IIS占用，因此将此处改为listen800;

。

并将

location/{

root 

html;

index 

index.htmlindex.htm;

改为：

index 

proxy_pass 

//backend;

proxy_redirect 

off;

proxy_set_header 

Host$host;

X-Real-IP$remote_addr;

X-Forwarded-For$proxy_add_x_forwarded_for;

client_max_body_size 

10m;

client_body_buffer_size 

128k;

proxy_connect_timeout 

90;

proxy_send_timeout 

proxy_read_timeout 

proxy_buffer_size 

4k;

proxy_buffers 

432k;

proxy_busy_buffers_size 

64k;

proxy_temp_file_write_size 

其中proxy_pass参数和upstreambackend{}对应。

经过上面这些步骤，负载均衡配置就完成，下面前分别启动两台tomcat，然后双击nginx根目录下的nginx.exe文件或者用startnginx启动nginx，打开浏览器，输入地址:

http:

//localhost:

800便可看到下面画面:

这说明已经成功跳转到Tomcat上面。

下面以来电秀具体项目为例，输入地址：

800/ldxwebpersonal/personal/index/index.action
