## 1.下载Nginx ##

[Nginx下载地址][Nginx]

**下载，解压后：**

**这样就把Nginx准备好了！**

## 2.我们准备一个Tomcat，比如我准备的是： ##

http://127.0.0.1:8082

## **3.把这个服务通过Nginx来代理：** ##

*  **首先把conf/nginx.conf的文件中的所有server节点删除：（所有server的节点都删掉）**

*  **然后添加一个server节点：**

listen       监听的端口

server\_name    Nginx的域名（ip地址也行）

location     匹配规则一般使用    /

proxy\_pass    代理服务器的实际地址

server {
    	listen 80;
    	server_name 192.168.1.107;
    	location / {
    		proxy_pass http://127.0.0.1:8082;
    	}
        }

*  **保存后，启动Nginx**

**在nginx文件的根目录下打开cmd，或双击nginx.exe（不推荐）**

在cmd中输入命令：

启动：start nginx

停止：nginx.exe -s stop

更改配置文件重新载入：nginx.exe -s reload

没有报错就成功启动！！

如果报错，原因：The system cannot find the file specified。找不到nginx.pid文件

*  **测试Nginx代理是否成功**

**访问我们配置文件的server\_name的值 ↑↑↑↑↑↑↑↑↑；**

## 4.通过Nginx实现负载均衡 ##

*  **准备两个服务器，进行负载均衡！！**

配置：注意upstream的名称和proxy\_pass的URL匹配

upstream panel {  
        server 127.0.0.1:8080;  
        server 127.0.0.1:8082;  
        } 
    
        server {
    	listen 80;
    	server_name 192.168.1.107;
    	    location / {
    		    proxy_pass http://panel;
    	    }
        }

**重新载入Nginx：nginx.exe -s reload**

*  **测试是否成功负载均衡：**

多次访问这个地址，在服务器的日志看到访问记录：
