二、负载均衡

2.1、概念

2.2、集群规划及实现

2.3、具体实现

2.3.1、克隆

使用之前的tomcat克隆一个tomcat2，记住要修改tomcat的ip地址，并用远程连接工具连上

2.3.2、修改tomcat1配置

cp -r /usr/apache-tomcat-9.0.52/ /usr/tomcat1
cp -r /usr/apache-tomcat-9.0.52/ /usr/tomcat2
cp -r /usr/apache-tomcat-9.0.52/ /usr/tomcat3

分别修改tomcat1，2，3的server.xml配置和随便改一个页面，知道访问的是当前端口下的项目就行：拿tomcat1举例

启动测试

/usr/tomcat1/bin/startup.sh
/usr/tomcat2/bin/startup.sh
/usr/tomcat3/bin/startup.sh

2.3.3、修改tomcat2配置

cp -r /usr/apache-tomcat-9.0.52/  /usr/tomcat4
cp -r /usr/apache-tomcat-9.0.52/  /usr/tomcat5
cp -r /usr/apache-tomcat-9.0.52/  /usr/tomcat6

修改配置和上面一样，这里就不演示了

启动测试

/usr/tomcat4/bin/startup.sh
/usr/tomcat5/bin/startup.sh
/usr/tomcat6/bin/startup.sh

2.3.4、负载均衡配置

2.3.4.1、轮询roundrobin(默认)

vim /usr/local/nginx/conf/nginx.conf

#重启nginx服务
/usr/local/nginx/sbin/nginx -s reload

测试：

2.3.4.2、weight：指定轮询权值

修改配置

vim /usr/local/nginx/conf/nginx.conf

upstream loadbalanceserver {
		server  192.168.37.181:8081;
		server  192.168.37.181:8082;
		server  192.168.37.181:8083 weight=50;
		server  192.168.37.182:8084;
		server  192.168.37.182:8085;
		server  192.168.37.182:8086 weight=100;
	}

重启nginx服务

/usr/local/nginx/sbin/nginx -s reload

2.3.4.3、ip_hash

upstream  myservers {
         ip_hash;
         server 192.168.170.11:8081;
         server 192.168.170.11:8082;
         server 192.168.170.11:8083 weight=20;
         server 192.168.170.12:8084;
         server 192.168.170.12:8085;
         server 192.168.170.12:8086;
    }

2.3.4.4、fair（公平）

不演示了

2.3.4.5、url_hash

不演示了
