Zookeeper错误：无法在选举地址打开通道X.
我在3个不同的aws服务器上安装了zookeeper。 以下是所有服务器中的配置
tickTime=2000 initLimit=10 syncLimit=5 dataDir=/var/zookeeper clientPort=2181 server.1=xxxx:2888:3888 server.2=xxxx:2888:3888 server.3=xxxx:2888:3888 所有这三个实例都在var/zookeeper上有一个myid文件，其中包含相应的id。 所有三台服务器都从aws控制台打开了所有端口。 但是当我运行zookeeper服务器时，我在所有实例中都收到以下错误。
2015-06-19 12:09:22,989 [myid:1] - WARN [QuorumPeer[myid=1]/0:0:0:0:0:0:0:0:2181:QuorumCnxManager@382] - Cannot open channel to 2 at election address /xxxx:3888 java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:200) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:579) at org.apache.zookeeper.server.quorum.QuorumCnxManager.connectOne(QuorumCnxManager.java:368) at org.apache.zookeeper.server.quorum.QuorumCnxManager.connectAll(QuorumCnxManager.java:402) at org.apache.zookeeper.server.quorum.FastLeaderElection.lookForLeader(FastLeaderElection.java:840) at org.apache.zookeeper.server.quorum.QuorumPeer.run(QuorumPeer.java:762) 2015-06-19 12:09:23,170 [myid:1] - WARN [QuorumPeer[myid=1]/0:0:0:0:0:0:0:0:2181:QuorumCnxManager@382] - Cannot open channel to 3 at election address /xxxx:3888 java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:200) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:579) at org.apache.zookeeper.server.quorum.QuorumCnxManager.connectOne(QuorumCnxManager.java:368) at org.apache.zookeeper.server.quorum.QuorumCnxManager.connectAll(QuorumCnxManager.java:402) at org.apache.zookeeper.server.quorum.FastLeaderElection.lookForLeader(FastLeaderElection.java:840) at org.apache.zookeeper.server.quorum.QuorumPeer.run(QuorumPeer.java:762) 2015-06-19 12:09:23,170 [myid:1] - INFO [QuorumPeer[myid=1]/0:0:0:0:0:0:0:0:2181:FastLeaderElection@849] - Notification time out: 25600
如何在每个节点中定义本地服务器的ip？ 如果您已经提供了公共IP，则侦听器将无法连接到该端口。 您必须为当前节点指定0.0.0.0
server.1=0.0.0.0:2888:3888 server.2=192.168.10.10:2888:3888 server.3=192.168.2.1:2888:3888
此更改也必须在其他节点上执行。
我遇到了保存问题并解决了它。
确保myid是在zoo.cfg中使用您的配置进行保存。
请检查conf目录中的zoo.cfg文件，其中包含此类内容。
server.1=zookeeper1:2888:3888 server.2=zookeeper2:2888:3888 server.3=zookeeper3:2888:3888
并检查服务器dataDir目录中的myid。 例如：
让我们说在zoo.cfg上定义的dataDir是'/home/admin/data'
然后在zookeeper1上，你必须有一个名为myid的文件，并且在这个文件中的值为1;在zookeeper2上，你必须有一个名为myid的文件，并且在这个文件上有值2; 在zookeeper3上，您必须有一个名为myid的文件，并且该文件的值为3。
如果没有像这样配置，服务器将侦听错误的ip：端口。
下面是一些ansible jinja2模板信息，用于在zoo.cfg中自动构建具有0.0.0.0主机名的集群
{% for url in zookeeper_hosts_list %} {%- set url_host = url.split(':')[0] -%} {%- if url_host == ansible_fqdn or url_host in ansible_all_ipv4_addresses -%} server.{{loop.index0}}=0.0.0.0:2888:3888 {% else %} server.{{loop.index0}}={{url_host}}:2888:3888 {% endif %} {% endfor %}
如果您自己的主机名解析为127.0.0.1（在我的情况下，主机名在/ etc / hosts中），zookeeper将无法在zoo.cfg文件中没有0.0.0.0的情况下启动，但如果您的主机名解析为实际机器的IP，您可以将它自己的主机名放在配置文件中。
这对我有用
Step 1: Node 1: zoo.cfg server.1= 0.0.0.0:: server.2= :: . . . server.n= :: Node 2 : server.1= :: server.2= 0.0.0.0:: . . . server.n= :: Now in location defined by datadir on your zoo.cfg Node 1: echo 1 > /id Node 2: echo 2 > /id . . . Node n: echo n > /id
这个帮助我成功地开始了动物饲养员，但是一旦我开始玩它就会知道更多。 希望这可以帮助。
在3节点动物园管理员合奏上有类似的问题。 解决方案是espeirasbora建议并重新启动。
所以这就是我所做的
zookeeper1，zookeeper2和zookeeper3
答：我的合奏中的问题 :: znodes无法启动
B.三台3台机器中的System SetUp :: 3 Znodes
C.错误::
在我的zookeper日志文件中，我可以看到以下错误

D.行动和决议::
在每个znode上。 我修改了配置文件$ ZOOKEEPER_HOME / conf / zoo.cfg，将机器IP设置为“0.0.0.0”，同时保持其他2个znode的IP地址。 湾 重新启动了znode c。 检查状态d.Voila，我很好

在我的案例中，问题是，我必须启动所有三个zookeeper服务器，然后才能使用./zkCli.sh连接到zookeeper服务器
