一、该问题的重现步骤是什么?
1. nacos, sentinel, redis, mysql, blade-admin, blade-log以及业务微服务均使用docker部署,参考script/docker-compose.yml方式
2. 所有服务均正常启动,各自功能均能正常访问
3. spring boot admin所有服务的sentinel状态为DOWN
4. 查询各微服务的健康信息:"sentinel":{"status":"DOWN","details":{"dataSource":{},"enabled":true,"dashboard":{"description":"172.30.0.58:8858 can't be connected","status":"DOWN"}}}, IP及端口(172.30.0.58:8858)均正确,但提示:can't be connected
5. 进入容器查看sentinel-record.log.2020-03-24.0提示:WARNING [SimpleHttpHeartbeatSender] Failed to send heartbeat to sentinel.docker_blade_net/172.30.0.58:8858 : java.net.ConnectException: Connection refused (Connection refused)
6. 同一容器内检查连通性:
curl 172.30.0.58:8858Sentinel Dashboard
bash-4.4# curl -i "172.30.0.58:8858/registry/machine?ip=172.30.0.9&port=8719" HTTP/1.1 200Content-Type: application/json;charset=UTF-8Transfer-Encoding: chunkedDate: Tue, 24 Mar 2020 13:52:03 GMT {"success":true,"code":0,"msg":"success","data":null}
bash-4.4# ip a 1: lo: mtu 65536 qdisc noqueue state UNKNOWN qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 713: eth0@if714: mtu 1500 qdisc noqueue state UP link/ether 02:42:ac:1e:00:09 brd ff:ff:ff:ff:ff:ff inet 172.30.0.9/16 brd 172.30.255.255 scope global eth0 valid_lft forever preferred_lft forever
二、你期待的结果是什么?实际看到的又是什么?
容器内的各微服务网络连通性正常,但sentinel心跳提示拒绝连接,微服务的sentinel健康状态为DOWN
三、你正在使用的是什么产品,什么版本?在什么操作系统上?
