1. Install Zookeeper standalone mode

Configuring the Java Environment

Download package

Installation

Start Zookeeper

2. Installing the Zookeeper Cluster

Zookeeper-1 192.168.3.19

Zookeeper-2 192.168.3.20

Zookeeper-1 Operation:

#停止zookeeper服务 [[email protected] ~]#/usr/local/zookeeper/bin/zkserver.sh stopjmx enabled by defaultusing Config:/usr/ local/zookee# Modify configuration file/usr/local/zookeeper/conf/zoo.cfg[[email protected] ~]# egrep-v "^$|^#"/usr/local/zookeeper/ Conf/zoo.cfg ticktime=2000initlimit=10synclimit=5datadir=/data/zookeeper/buildclientport=2181datalogdir=/data/ Zookeeper/logsserver.1 = 192.168.3.19:2888:3888server.2 = 192.168.3.20:2888:3888# configuration Myid[[email protected] ~]# CAT/ Data/zookeeper/build/myid 1

Zookeeper-2 need to install Java and zookeeper, see the procedure above

#配置文件内容如下 [[email protected] conf]# egrep-v "^$|^#"/usr/local/zookeeper/conf/zoo.cfg ticktime=2000initlimit= 10synclimit=5datadir=/data/zookeeper/buildclientport=2181datalogdir=/data/zookeeper/logsserver.1 = 192.168.3.19:2888:3888server.2 = 192.168.3.20:2888:3888# start service [[email protected] ~]#/usr/local/zookeeper/bin/ zkserver.sh startjmx enabled by defaultusing Config:/usr/local/zookeeper/bin/. /conf/zoo.cfgstarting Zookeeper ...

Finally verify the cluster status
