Zookeeper distributed architecture of the installation and testing of Cluster Setup instructions zookeeper

1. Zookeeper installation

Test JDK 1.1

1.2 Upload Package

zookeeper's official website: https: //zookeeper.apache.org/releases.html

1.3-extracting archive

tar -xvf zookeeper-3.4.14.tar.gz

1.4 delete archive, extract the files renamed zookeeper (custom)

1.5 Creating data and log files

1.6 zoo.cfg modify configuration files

1.6.1 into the data file pwd, copy its path

1.6.2 Changing zoo_sample.cfg file named zoo.cfg

1.6.3 modify dataDir path, which is just a data path (dataLogDir similar)

1.7 is installed successfully detect Zooleeper

1.7.1 file into the bin directory, through sh zkServer.sh start open

1.7.2 opening, through  sh zkServer.sh status detection state,

Status is displayed as standalone Description On success, your success install Zookeeper! ! !

2.Zookeeper Cluster Setup

2.1 Preparations

2.1.1 Creating zkCluster file again zookeeper's root directory, which then create zk1 / zk2 / zk3 three folders

2.1.2 Creating data and log files in three folders - mkdir {zk1,zk2,zk3}  shentuylzc.cn  {data,log}

2.2 Creating myid

2.2.1 Different document have different myidmyid -----www.yixingylzc.cn zk1 content of 1, zk2 is 2, zk3 3

2.3 edit the configuration file

2.3.1 copy the path of zk1

2.3.2 After modifying the configuration file is copied to zoo_www.shentuylgw.cn sample.cfg zoo1.cfg in the conf directory.

2.3.3 vim zoo1.cfg - >> change the configuration

• DataLogDir dataDir path and data path and to use the corresponding log
• The last digit of 2181 clientPort corresponding, simply follow myid numbers in the configuration, without modifying the remaining three
• server.1 / 2/3 is superimposed on a part of the way, easy to remember
• zoo2.cfg / zoo3.cfg just as I described above can change
• Remember server.1 / 2/3 does not need to change the configuration only once

2.4 Test Cluster Setup successful

sh zkServer.sh start   www.lexuancaizc.cn zoo1.cfg     开启
sh zkServer.sh stop    www.baishiyl2zc.cn zoo1.cfg     关闭
sh zkServer.sh status  www.motianydl.cn    zoo1.cfg     检测状态

2.4.1 In the figure I only opened the zoo1.cfg / zoo2.cfg ---- >> live from my box can be seen, zoo2.cfg for the host, zoo1.cfg from the machine, if zoo3.cfg open , still zoo2.cfg slave

Zookeeper cluster build success! ! !
