*  **Nginx 配置反向代理实例**

**实现效果：直接输入ip地址即可跳转到 Tomcat 主页**

**1. 修改 nginx 如下配置：**

server { 
            listen       80;
            server_name  localhost;
    
            #charset koi8-r;
    
            #access_log logs/host.access.log main;
    
            location / { 
                root   html;
                proxy_pass  http://127.0.0.1:8080;
                index  index.html index.htm;
            }

**2. 重新加载 nginx ：**

./nginx -s reload

**3. 访问 http://118.31.106.51/**

**实现效果：不同地址跳转到不同端口**

server { 
            listen       9001;
            server_name  localhost;
    
            location ~ /blog/ { 
                proxy_pass  http://127.0.0.1:8081;
            }
        
            location ~ /tomcat/ { 
                proxy_pass  http://127.0.0.1:8080;
            }
        }

--------------------

*  **Nginx 配置负载均衡实例（默认策略为轮询）**

http { 
    	upstream myserver { 
    		server	192.168.17.129:8080;
    		server	192.168.17.129:8081;
    		server	192.168.17.129:8082;
    	}
    
    	server { 
    		listen	80;
    		server_name	localhost;
    
    		location / { 
    			proxy_pass http://myserver;
    			root	html;
    			index	index.html	index.htm;
    		}
    	}
    	
    }

*  **Nginx 配置负载均衡实例（根据权重分配）**

http { 
    	upstream myserver { 
    		server	192.168.17.129:8080	weight=5;
    		server	192.168.17.129:8081 weight=10;
    		server	192.168.17.129:8082 weight=5;
    	}

*  **Nginx 配置负载均衡实例（根据访问ip的hash分配，可以解决session问题）**

upstream myserver { 
    	ip_hash;
    	server	192.168.17.129:8080;
    	server	192.168.17.129:8081;
    	server	192.168.17.129:8082;
    }

*  **Nginx 配置负载均衡实例（根据后端服务器的响应时间来分配）**

upstream myserver { 
       server	192.168.17.129:8080;
       server	192.168.17.129:8081;
       server	192.168.17.129:8082;
       fair;
    }
