Zookeeper cluster deployment

Zookeeper cluster deployment

I. Preparations before deployment

1. Ensure normal communication between hosts, preferably in the same network segment.

2. Modify the host file and add the ing between the IP address and the host name. The method is to modify the/etc/hosts and etc/hostname files. The methods for different Linux distributions are not necessarily the same.

3. open the port to be used or close the Firewall

2. Deploy the Zookeeper Cluster

1. Visit the official website to download the Zookeeper installation package and decompress it.

Tar-xvzf zookeeper-3.4.6.tar.gz

2. Create a data directory

Run the following command to create a data directory:

Mkdir/usr/zookeeper/data

Run the following command to create a log directory:

Mkdir/usr/zookeeper/data/log

Run the following command to create the myid file and write the ID:

Echo 1>/usr/zookeeper/data/myid

3. modify configuration

Run the following command to edit the zoo. cfg file:

Cd zookeeper-3.4.6/conf/& mv zoo_sample.cfg zoo. cfg & vi zoo. cfg

Modify the configuration as follows:

DataDir =/usr/zookeeper/data

DataLogDir =/usr/zookeeper/data/log

Autopurge. snapRetainCount = 3

Autopurge. purgeInterval = 1

Add the node addresses of the Zookeeper cluster at the end:

Server.1 = node1: 2888: 3888

Server.2 = node2: 2888: 3888

Server.3 = node3: 2888: 3888

4. Copy the configuration file to another node.

Zookeeper-3.4.6/node2:/usr/

Note that the myid in each node cannot be the same.

3. Start the Zookeeper Cluster

Run the following command on each node of the Zookeeper cluster to start the Zookeeper service:

Zookeeper-3.4.6/bin/zkServer. sh start

Run the following command to view the status of each node in the Zookeeper cluster:

Zookeeper-3.4.6/bin/zkServer. sh status

The node node1 is a follewer node.

4. Verify HA's automatic failover

Run the jps command to view the Zookeeper process.

Use the kill-9 2432 command to kill the leader process, and then view the Zookeeper status of each node. If one of the nodes is leader, it is verified to be easy to use.
