ZooKeeper Installation(Dev)

ZooKeeper Installation

Install ZooKeeper packages

# -jre-headless
# sudo apt-get install zookeeper zookeeperd

If you need a cluster, configure the Conf file, otherwise ignore it.

Configure ZooKeeper

Common Configuration

Edit the /etc/zookeeper/conf/zoo.cfg file to contain the following:

server.=nsdb1::
server.=nsdb2::
server.=nsdb3::
autopurge.snapRetainCount=
autopurge.purgeInterval =
[Important]    Important
For production deployments it is recommended to configure the storage of snapshots in a different disk than the commit log, this is done by setting the parameters dataDir and dataLogDir in zoo.cfg. In addition we advice to use an SSD drive for the commit log.

Node-specific Configuration

NSDB Node 

Create the /var/lib/zookeeper/myid file and edit it to contain the host’s ID:

#  > /var/lib/zookeeper/myid
NSDB Node 

Create the /var/lib/zookeeper/myid file and edit it to contain the host’s ID:

#  > /var/lib/zookeeper/myid
NSDB Node 

Create the /var/lib/zookeeper/myid file and edit it to contain the host’s ID:

#  > /var/lib/zookeeper/myid
