ec2上的动物园管理员无法运行

Question

各位，我最近在ec2上设置了zookeeper。我遵循了ec2的手册，但它仍然显示了错误：

root@ip-172-31-15-65:/home/yjiang/zookeeper-3.4.5/bin# ./zkServer.sh status
JMX enabled by default
Using config: /home/yjiang/zookeeper-3.4.5/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

但该实例正在后台运行。然后当我使用/zkCli。sh–server-server-server-ip:2181命令，如下所示

root@ip-172-31-15-68:/home/yjiang/zookeeper-3.4.5/bin# ./zkCli.sh -server ec2-54-213-208-202.us-west-2.compute.amazonaws.com:2181

连接似乎要花很长时间。

我根据文档做了所有的设置，我不知道我做错了什么。下面是我的conf文件，myid位于dataDir文件夹中

# 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=/home/yjiang/zookeeper/data/zk1
# the port at which the clients will connect
clientPort=2181
server.1=localhost:2888:3888
server.2=ec2-54-213-208-202.us-west-2.compute.amazonaws.com:2888:3888
#server.3=ec2-54-213-208-225.us-west-2.compute.amazonaws.com:2888:3888
#server.4=ip-172-31-15-66.us-west-2.compute.internal:3888
#server.5=ip-172-31-26-18.us-west-2.compute.internal:3888
#
# 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

仅供参考，我已将端口2181、2888和3888添加到所有计算机的防火墙中。我甚至在所有机器上都禁用了防火墙，它仍然不工作。但使用相同的配置方法，在我的本地环境中从来没有任何问题。请帮帮我，非常感谢。

问题可能与AWS间隔与外部地址有关。每个EC2实例都有一个在AWS内部使用的地址（私有地址）和一个在AWS外部使用的地址。您的配置文件显示server2使用ec2-54-213-208-202.us-west-2.compute.amazonaws.com这绝对是一个外部地址。如果您的所有服务器和AWS中的所有服务器都确保它们都使用私有地址。
