k8s上部署zookeeper叢集報錯java.net.BindException: Cannot assign requested address (Bind failed)

部署

1.配置3個POD部署zookeeper節點，

2.分别使用clusterIP暴露2888，3888端口

3.配置環境變量

ZOO_SERVERS=“server.1=zookeeper-cluster-1.test.svc.cluster.local:2888:3888;2181 server.2=zookeeper-cluster-2.test.svc.cluster.local:2888:3888;2181 server.3=zookeeper-cluster-3.test.svc.cluster.local:2888:3888;2181”

MY_ZOO_ID=1

報錯

2021-11-11 00:46:39,727 [myid:1] - ERROR [ListenerHandler-zookeeper-cluster-1.test.svc.cluster.local/172.24.166.69:3888:QuorumCnxManager

Listener

ListenerHandler@1094] - Exception while listening

java.net.BindException: Cannot assign requested address (Bind failed)

原因

因為3888端口通過K8S服務暴露，需要添加配置項quorumListenOnAllIPs=true以保證掃描所有網卡

解決

通過環境變量添加配置項

ZOO_CFG_EXTRA=“quorumListenOnAllIPs=true”
