Hi, Everyone,=20

I am recently setting up zookeeper on ec2

I have followed the suggestion that using the internal ip of ec2, but it =
still shows up the error:

=20

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.

=20

But the instance is running in the background.

Then when I use the ./zkCli.sh =E2=80=93server server-ip:2181 command, =
it shows below

=20

It seems take forever to connect.

I did setup everything according to docs, I don=E2=80=99t know what I =
did wrong.

The following is my conf file, and the myid is in the dataDir folder

=20

# The number of milliseconds of each tick

tickTime=3D2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=3D10

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=3D5

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=3D/home/yjiang/zookeeper/data/zk2

# the port at which the clients will connect

clientPort=3D2181

server.1=3Dip-172-31-15-68.us-west-2.compute.internal:2888:3888

server.2=3Dlocalhost:2888:3888

server.3=3Dip-172-31-15-67.us-west-2.compute.internal:2888:3888

#server.4=3Dip-172-31-15-66.us-west-2.compute.internal:2888:3888

#server.5=3Dip-172-31-26-18.us-west-2.compute.internal:2888:3888

#

# Be sure to read the maintenance section of the

# administrator guide before turning on autopurge.

#

# =
http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenanc=
e

#

# The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3D3

# Purge task interval in hours

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=3D1

=20

FYI I have added the port 2181, 2888 and 3888 to my firewalls in all =
machines. I even disabled the firewall in all machines, it still =
doesn=E2=80=99t work

Please help me

Thanks a lot.
