Question

我正在配置三个mesos主人，现在正在设置zookeeper。 zoo.cfg：

＆＃13;

server.1=cersei-master1:2888:3888
server.2=tywin-master2:2888:3888
server.3=jaime-master3:2888:3888
maxClientCnxns=50
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181

＆＃13;

zookeeper登录cersei-master1：

＆＃13;

＆＃13;

我的主机名位于/ etc / hosts

＆＃13;

127.0.0.1   cersei-master1 localhost localhost.localdomain localhost4 localhost4.localdomain4

＆＃13;

我还为zoo.cfg设置了ip＆＃39; s和0.0.0.0为当前节点。空空如也。我做错了什么？

提前致谢

Answer 1

当我尝试在群集模式下运行zookeeper时遇到了同样的问题。我正在使用centos 7 OS。如果您使用相同的。尝试刷新Iptables

iptables -F

并重新启动zookeeper。它将开始。

zookeeper给出了一个unknownhostexception
