"java.net.ConnectException: Connection refused" in zookeeper -

-

i installed zookeeper follows : 

wget http://archive.cloudera.com/cdh/3/zookeeper-3.3.3-cdh3u1.tar.gz

here zoo.cf:

# number of milliseconds of each tick ticktime=2000 # number of ticks initial # synchronization phase can take initlimit=10 # number of ticks can pass between # sending request , getting acknowledgement synclimit=5 # directory snapshot stored. datadir=/home/reach121/basf/data/zookeeper/data1 # maximum client connection maxclientcnxns=500 # port @ clients connect clientport=2183 server.1=localhost:2878:3878 server.2=localhost:2879:3879 server.3=localhost:2880:3880

and started 

/bin/zkserver.sh start zoo.cfg

and when do? 

bin/zkcli.sh -server 127.0.0.1:2183

it gives me error:

are servers coming up? not given:

server.1=localhost:2878:3878 server.2=localhost:2879:3879 server.3=localhost:2880:3880

if running 3 servers on same host need each have different config - in particular datadir location must different, , need assure each datadir has myid file corresponding server line (ie server.# in config).

typically when want run in distributed mode need have separate hosts. in case why not run in standalone (default) mode?

i'd suggest read more in admin guide first: http://zookeeper.apache.org/doc/r3.3.3/zookeeperadmin.html
