Zookeeper cluster building tutorial, zookeeper cluster building

1. There are three nodes in total (the zk server cluster is no less than three nodes), and the system time between servers must be consistent.

2 unzip tarzookeeper-3.4.5.tar.gz

3 rename mvzookeeper-3.4.5 zookeeper

4. Modify the environment variable vi/etc/profile.

Export zookeeper_home =/usr/local/zookeeper

Exportpath =.; $ zookeeper_home/bin; $ JAVA_HOME /...

5. Refresh Source/etc/profile

6. modify the configuration file under zookeeper

Cd/usr/local/zookeeper/conf

Mvzoo_sample.cfg zoo. cfg

7. Modify conf vi zoo. cfg

1 dataDir =/usr/local/zookeeper/data

2. Create a myid file under the configured dataDir file and write 0 to the myid file (server.0 writes 0, server.1 writes 1, and server.2 writes 2)

3. Add

Server.0 = ip: 2888: 3888

Server.1 = ip: 2888: 3888

Server.2 = ip: 2888: 3888

8. Create the folder data in the/usr/local/zookeeper/directory.

9 start zookeeper:

ZkServer. sh start in the bin directory

View status zkServer. sh status

After zkCli. sh enters the zookeeper client

Search for ls/zookeeper

Create and assign values to create/key value

Get/key

Set/key value

We can see the data consistency of the zookeeper cluster.

Rmr/path recursively Delete nodes

Delete/path/child Delete a specified Node
