最近在學 zookeeper ,按照 docker 官網的方式集羣 zookeeper , 而後發現有路由找不到。最後問題解決了，隨手記錄下來。 
java
緣由是 firewalld 的沒有信任 docker 的 ip 地址，stackoverflower 中也有相似的問題。 將全部 docker 的 ip 添加都白名單便可。docker
解決過程以下：bash
ifconfig
br-0e1da8b59f79: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 172.19.0.1 netmask 255.255.0.0 broadcast 172.19.255.255

將 ip 添加到信任區域elasticsearch
firewall-cmd --zone=trusted --add-source=172.17.0.1/16 --permanent firewall-cmd --zone=trusted --add-source=172.18.0.1/16 --permanent firewall-cmd --zone=trusted --add-source=172.19.0.1/16 --permanent firewall-cmd --reload
