linux下安装

1.下载  
wget https://releases.hashicorp.com/consul/1.7.3/consul\_1.7.3\_linux\_amd64.zip  
2.解压  
unzip consul\_1.7.3\_linux\_amd64.zip  
3.移动到全局变量  
mv consul /usr/local/bin/consul  
4.查看  
consul --version  
5.启动（使用开发模式启动）  
1）consul agent -dev //localhost访问  
2）consul agent -dev -client 0.0.0.0 -ui //IP访问  
6.访问  
netstat -nptl //查看端口8500  
ps -ef|grep consul //查看进程编号  
kill -15 进程号 //杀死进程

windows下  
下载完解压就可以看到consul.exe了  
双击运行。进入命令行窗口  
查看版本 consul --version  
开发者模式启动 consul agent -dev  
访问 http;//localhost:8500

        	public static void main(String[] args) { 
        		SpringApplication.run(CsPaymentApplication.class,args);
        	}
        }

4.业务类

        	@Value("${server.port}")
        	private String serverPort;
    
        	@GetMapping(value = "/consul")
        	public String paymentConsul(){ 
        		return "consul port: "+serverPort+"\t"+ UUID.randomUUID().toString();
        	}
    
        }
