"Hadoop Distributed Deployment Eight: Distributed collaboration framework zookeeper architecture features explained and local mode installation deployment and command use"

What is Zookeeper

is an open source, distributed, Apache project that provides collaborative services for distributed applications

Provides a simple set of primitives so that with distributed applications can build higher-level synchronization services on top of him

The design is very simple and easy to program, and he uses a tree-like data structure similar to that of a file system.

The goal is to have distributed services no longer need to have collaboration conflicts and to implement collaborative services in addition

From the point of view of design pattern, it is a distributed service management framework based on the observer design pattern.

Stop the services on the node first

Execute the command on node one: sbin/stop-dfs.sh

　　　　

　　　　

Then execute the command on node two: sbin/stop-yarn.sh

　　　　

　　　　

Upload the Zookeeper file up

　　　　

Then set the Zookeeper permissions to executable

　　　　

　　　　

Extract zookeeper to/opt/moudles using command: TAR-ZXVF zookeeper-3.4.5.tar.gz-c/opt/modules/

　　　　

Next modify the Zookeeper configuration file

To modify the configuration file name

　　　　　　

Create a folder in the Zookeeper directory

　　　　　　

　　　　　　

Copy this path, and then go to config file to modify this, and the rest do not need to be modified

　　　　　　

　　　　　　

After the configuration is complete, start zookeeper, and in the Zookeeper directory, execute the command: bin/zkserver.sh start

　　　　　　

　　　　　　

View zookeeper status can be seen as a stand-alone node

　　　　　　

command to enter the client: bin/zkcli.sh

　　　　　　

To create a command for a node:

Create/test "Test-data"

　　　　　　

View node Command LS/

　　　　　　

Gets the node command get/test (the data below is the attribute information for this node)

　　　　　　

　　　　　　　

Delete node: rmr/test

　　　　　　

　　　　　　

Here, the local installation is over!
