转（：搭建zookeeper集群

1.需要装java环境  centos7+jdk1.8

1.1卸载默认的openjdk

    rpm -qa |grep java

    rpm -e  java-1.8.0-openjdk

1.2安装java

     解压 tar xf ....

     配置环境变量

     vim /etc/profile          

        export JAVA_HOME=/usr/local/java/jdk1.8.0_161
        export JRE_HOME=/usr/local/java/jdk1.8.0_161/jre
        export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
        export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

1.3检查java是否安装成功

2.三台机器 安装zookeeper

2.1  解压zookeeper

2.3 配置环境变量

export ZK_HOME=/usr/local/zookeeper-3.4.11
export PATH=$ZK_HOME/bin:$PATH

2.4 修改zookeeper配置文件

dataDir=/usr/local/zookeeper-3.4.11/data

server.0=192.168.192.128:2888:3888
server.1=192.168.192.129:2888:3888
server.2=192.168.192.130:2888:3888  //server.X

2.5创建数据目录

 cd /usr/local/zookeeper-3.4.11

mkdir data

vim myid

X

2.6启动服务

source /etc/profile

zkServer.sh start

zkServer.sh status
