Linux installation Configuration zookeeper-3.4.10

Install Zookeeper:

: http://mirror.bit.edu.cn/apache/zookeeper/

The ZK node is preferably an odd number, which makes it easy to select the leader node in the node;

Upload the zookeeper-3.4.10 installation package to the/software directory:

TAR-ZXVF zookeeper-3.4. Ten

Decompression to the/software;
Enter zookeeper-3.4.10 create folder data;

Mkdir-p/software/zookeeper-3.4. Ten/data

Create file myID under Data, content is 1;

" 1 ">>/software/zookeeper-3.4. Ten/data/myid

Enter conf, copy a zoo_sample.cfg named zoo.cfg;

CP Zoo_sample.cfg Zoo.cfg

Modify ZOO.CFG Content:

datadir=/software/zookeeper-3.4. Ten/data

#这里是zookeeper快照目录, recommendations based on actual modifications

The last line is added:

Format: Server.serverid=hostname:lfport:txport

# ServerID is the ID number of the ZK node

# hostname is host name

# Lfport is the communication port between leader and follower (default 2888)

# Txport is an election leader communication port between follower (default 3888)

Server. 1=slave01:2888:3888   #server. 1 in 1 is the ID, followed by the hostname and port number server. 2=salve02:2888:3888server. 3=slave03:2888:3888

Then change the permissions of the zookeeper-3.4.10 folder to Hadoop;

Chown-r hadoop:hadoop/software/zookeeper-3.4. Ten

Other node installation simply copy the entire zookeeper-3.4.10 directory to the same folder as the other nodes/software below, and modify the myID file under data to the respective ID:

Scp-r Hadoop1:/hadoop/zookeeper

"2" >/software/zookeeper-3.4.10/data/myid

For convenience, you can add the zookeeper executable directory to the PATH environment variable:

path=/software/zookeeper-3.4. ten/bin;

/software/zookeeper-3.4.10/bin directory on each node, respectively

Start./zkserver.sh start;

View the startup status./zkserver.sh status

Stop./zkserver.sh stop

Using JPS to view the process will be more than: Quorumpeermain

Use Zkcli.sh-server Ip:port to connect to the zookeeper cluster with the following syntax:

127.0. 0.1:2181
