zookeeper cluster configuration on two servers

I want to build a cluster using zookeeper, but I just get 2 servers(A,B). If I install two zookeepers(z1, z2) on server A, and one(z3) on server B. Can this cluster work? In fact, I have configured my servers like this. z2 can start, but I can not check its status. And z1 and z3 are standalone mode. How to configure? Thanks.

Can this cluster work?

Yes, you can install three instances on two servers. You just need different configurations for z1 and z2.

Use the following configuration for z1.

# z1 configuration
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data/z1
clientPort=2181
server.1=A:2888:3888
server.2=A:2889:3889
server.3=B:2888:3888

and this one for z2.

# z2 configuration
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data/z2
clientPort=2182
server.1=A:2888:3888
server.2=A:2889:3889
server.3=B:2888:3888

on z3 configuration you need to have these lines. So z3 will be aware of z1 and z2. If you don't add these, z1 and z2 will be running standalone.

server.1=A:2888:3888
server.2=A:2889:3889
server.3=B:2888:3888

To check the status of a node, simply look inside zookeper.out file under dataDir. It will print enough information about the status.
