Question

我正在尝试使用下面的配置设置一个zookeeper实例，但是开始日志表明zookeeper在尝试绑定端口2181时暂停。可以在这里告诉我一些问题。谢谢。

Zookeeper配置文件。

    # The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/opt/zookeeper/data
# the port at which the clients will connect
clientPort=2181
#log directory.
dataLogDir=/opt/zookeeper/log

server.1=localhost:2888:3888

# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

Answer 1

我建议您从配置文件中删除以下行

server.1=localhost:2888:3888

然后重新启动服务器。

Answer 2

在CentOS上，您可以编辑以下文件并为_JAVA_OPTIONS添加行

sudo vim /etc/default/zookeeper

导出_JAVA_OPTIONS =“-Djava.net.preferIPv4Stack = true”

然后重新启动过程

sudo service zookeeper-server restart

Answer 3

我想提一下，当您收到以下日志消息时，这意味着服务器实际上已启动。

INFO  [main:NIOServerCnxnFactory@94] - binding to port 0.0.0.0/0.0.0.0:2181

如果您有一个如下所示的单个zookeeper实例，您看到的ERROR消息实际上是一个警告而不是错误。

2014-07-18 16:00:48,980 [myid:] - ERROR [main:QuorumPeerConfig@289] - Invalid configuration, only one server specified (ignoring)

Answer 4

尝试将此添加到zoo.cfg中 quorumListenOnAllIPs=true

Answer 5

你在Windows 64位上运行zookeeper吗？我遇到了同样的问题，但后来发现Win64不受支持。请参阅Zookeeper链接http://zookeeper.apache.org/doc/r3.4.5/zookeeperAdmin.html#sc_supportedPlatforms

设置单个Zookeeper实例并且绑定失败
