按照教程，elasticsearch 和 kibana 容器都起了，但是訪問 http//localhost:5601，一直只有冰冷的幾個字母：
Kibana server is not ready yet
docker logs kibana打印日志，報錯：
{"type":"log","@timestamp":"2020-06-04T08:25:57Z","tags":["warning","elasticsearch","admin"],"pid":6,"message":"Unable to revive connection: http://172.17.0.2:9200/"}
{"type":"log","@timestamp":"2020-06-04T08:25:57Z","tags":["warning","elasticsearch","admin"],"pid":6,"message":"No living connections"}
容器 ip 是沒問題的，es 服務也確實起了，為什么呢？？這個問題花了我大半天的時間，找遍了網上的教程都, 翻了官網上kibana手冊，都沒有相關的記錄
只能自己摸索
進入kibana容器中
docker exec -it kibana /bin/bash
bash-4.2$ ping 172.17.0.2 #沒有問題，能ping通
...
bash-4.2$ curl http://120.79.43.44:9200
curl: (7) Failed connect to 120.79.43.44:9200; No route to host
問題就出在這里！容器之間無法進行通信，猜測是防火牆的問題，再單獨搜索這個問題，找到了解決的方案
依次執行以下命令
nmcli connection modify docker0 connection.zone trusted
systemctl stop NetworkManager.service
firewall-cmd --permanent --zone=trusted --change-interface=docker0
systemctl start NetworkManager.service
nmcli connection modify docker0 connection.zone trusted
systemctl restart docker.service
即把 docker0 加入防火牆白名單
重新啟動容器，訪問地址 http://localhost:5601 ，顯示正在加載 kibana 圖像，總算沒有了 Kibana server is not ready yet。
