- - 3.1：该业务服务ip默认本地，和端口，sentinel会进行拦截
  - 3.2：postman发送请求
  - 3.3：查看Sentinel客户端

一：运行Sentinel服务

java -Dserver.port=8879 -Dcsp.sentinel.dashboard.server=localhost:8879 -Dproject.name=sentinel-dashboard -Dsentinel.dashboard.auth.username=admin -Dsentinel.dashboard.auth.password=admin -jar sentinel-dashboard-1.8.6.jar > log.file  2>&1 &

[root@localhost sentinal]# pwd
/usr/local/home/sentinal
[root@localhost sentinal]# ls
log.file  sentinel-dashboard-1.8.6.jar
[root@localhost sentinal]# pwd
/usr/local/home/sentinal
[root@localhost sentinal]# ps -ef | grep "java"
root      3178  1750  1 01:55 pts/0    00:00:09 java -Dserver.port=8879 -Dcsp.sentinel.dashboard.server=localhost:8887 -Dproject.name=sentinel-dashboard -Dsentinel.dashboard.auth.username=admin -Dsentinel.dashboard.auth.password=admin -jar sentinel-dashboard-1.8.6.jar
root      3284  1750 15 02:07 pts/0    00:00:05 java -Dserver.port=8879 -Dcsp.sentinel.dashboard.server=localhost:8887 -Dproject.name=sentinel-dashboard -Dsentinel.dashboard.auth.username=admin -Dsentinel.dashboard.auth.password=admin -jar sentinel-dashboard-1.8.6.jar
root      3312  1750  0 02:08 pts/0    00:00:00 grep --color=auto java
[root@localhost sentinal]# kill 3178
[root@localhost sentinal]# kill 3178
-bash: kill: (3178) - 没有那个进程
[1]-  退出 143              java -Dserver.port=8879 -Dcsp.sentinel.dashboard.server=localhost:8887 -Dproject.name=sentinel-dashboard -Dsentinel.dashboard.auth.username=admin -Dsentinel.dashboard.auth.password=admin -jar sentinel-dashboard-1.8.6.jar > log.file 2>&1
[root@localhost sentinal]# java -Dserver.port=8879 -Dcsp.sentinel.dashboard.server=localhost:8879 -Dproject.name=sentinel-dashboard -Dsentinel.dashboard.auth.username=admin -Dsentinel.dashboard.auth.password=admin -jar sentinel-dashboard-1.8.6.jar > log.file  2>&1 &

二：安装Sentinel依赖

2.1：Sentinel Pom依赖

在这里插入图片描述

这里Sentinel依赖信息可以单独放在common模块作为一组件common-sentinel供其他服务引用该依赖

   <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
    </dependency>

2.2：Sentinel YML 配置

注意：clientIp.localhost不同sentinel版本依赖缩进层级结构可能不一样，可根据idea提示回车

server:
  port: 8092
spring:
  application:
    name: chain-order-server
  rabbitmq:
    host: 192..101
    port: 5672
    username: root
    password: 123456
  cloud:
    nacos:
      config:
        server-addr: 101..62:8848
        file-extension: yaml
      discovery:
        server-addr: 101..62:8848
    sentinel:
      transport:
        dashboard: 192..104:8879 # sentinel dashboard地址
        port: 8879
        clientIp:
          localhost: 8092 # 该订单服务默认ip localhost和订单服务端口
      eager: true
