Not able to start zookeeper

Question

I am trying to manually start zookeeper. I run

# source zkServer.sh start

It outputs:

JMX enabled by default
Using config: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

When I run #jps, it outputs

15360 QuorumPeerMain
15412 Jps

From what I read online, Zookeeper is the same process as QuorumPeerMain listed above. But then when I check its status using

source zkServer.sh status

It hangs at:

JMX enabled by default
Using config: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg

So I run

#source zkServer.sh status > templogs.txt

Running above makes terminal to flash below for a moment (I have to run this command many times to read what actually is output on terminal before it closes) and closes terminal

JMX enabled by default
Using config:
grep: No such file or directory
grep: No such file or directory

Writing to templogs.txt following

Error contacting service. It is probably not running.

When I open zookeeper.out, I can see this output:

Is it like zookeeper stuck at obtaining bindings to port 2181?

But when I run lsof -i:2181 -s, it outputs:

COMMAND   PID USER   FD   TYPE   DEVICE SIZE NODE NAME
java    15360 root  467u  IPv6 18340028       TCP *:eforward (LISTEN)

The pid is that of the QuorumPeerMain.

Running source zkServer.sh status on another PC, properly gives

Mode: standalone

But on this PC, I am pretty much screwed. Can anyone help me.

Answer 1

In my case zookeeper 3.7.0. just need shutdown tomcat server

Answer 2

In my case i not install JAVA

so it was not started

please download JDK and install then try again

Answer 3

It seems some problem with the PORT binding

"binding to port 0.0.0.0/0.0.0.0:2181"

and the problem should be resolved by adding below the host entry to the hosts file

127.0.0.1 localhost

Answer 4

Have you validated that the config file is fine?

Try to run Zookeeper with the config file full path

Example: zkServer.sh start /etc/zookeeper/conf/zoo.cfg
