Nginx（web服务器）与Tomcat（应用服务器）搭建集群

Nginx作为互联网最常用的web服务器，高性能的HTTP和反向代理使它经常作为Tomcat集群的方案。Nginx官方只支持使用HTTP协议的集成，但是如果你想使用AJP协议集成，可以使用阿里开源的nginx\_ajp\_module。接下来我们使用HTTP的方式集成：

1.准备Nginx、Tomcat1、Tomcat2

Nginx下载并启动：[http://nginx.org/en/download.html][http_nginx.org_en_download.html]

nginx默认端口80，我这里为了方便也就不修改了，直接启动

server {
            listen       80;
            server_name  localhost;
    
            location / {
                root   html;
                index  index.html index.htm;
            }
    
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
            
        }

Tomcat下载并启动：[https://tomcat.apache.org/download-80.cgi\#8.5.43][https_tomcat.apache.org_download-80.cgi_8.5.43]

tomcat由于是同一台机器，我这里修改了端口号，配置分别是：

修改好配置，把示列工程sample1放在tomcat1，sample2放在tomcat2里面，启动两个tomcat：

访问http://localhost:8081/sample1/

访问http://localhost:8082/sample2/

2.配置Nginx，将Nginx与Tomcat1、Tomcat2集成

Nginx集成可以使用HTTP方式，也可以使用AJP方式，这里使用的HTTP方式。

2.1修改nginx的目录下conf下nginx.conf配置

在http\{\}下面配置

#配置服务器1
        upstream sample1{
          server localhost:8081;
        }
        #配置服务器2
        upstream sample2{
          server localhost:8082;
        }

在server\{\}下配置

#映射服务器1
            location /sample1/ {
                proxy_pass http://sample1;
            }
            #映射服务器2
            location /sample2/ {
                proxy_pass http://sample2;
            }

重启nginx，再一次访问

http://localhost/sample1/

http://localhost/sample2/

![1347563-20190803151112498-326748720.png][]

3.负载均衡配置

在http\{\}下面配置

#负载均衡配置服务器群组
        upstream sample1{
          #实例1
          server localhost:8081 weight=1 max_fails=3 fail_timeout=30s;
          #实例2
          server localhost:8082 weight=1 max_fails=3 fail_timeout=30s;
        }

在server\{\}下配置

#映射服务器集群
            location /sample1/{
              proxy_pass http://sample1;
            }

因为这里我们配置的两个项目是不同名称的，所以负载均和1：1时候，会有一个是无法访问。

在tomcat2里面把tomcat1里面的sample1复制过来，显示改为hello,tomcat2!

访问http://localhost/sample1/，不断刷新
