ZooKeeper

1，建立配置文件

进入ZooKeeper的conf文件夹

cd~/apache-zookeeper-3.7.0-bin/conf

zoo1.cfg

sudo gedit zoo1.cfg

插入内容：

initLimit=10
syncLimit=5
# zookeeper存储文件的位置
dataDir=/home/hadoop/apache-zookeeper-3.7.0-bin/1.data
# zookeeper日志文件的位置
dataLogDir=/home/hadoop/apache-zookeeper-3.7.0-bin/1.logs
# zookeeper供客户端连接的端口，默认是2181
clientPort=2181
# 设置三个节点
server.1=192.168.2.134:20881:30881 
server.2=192.168.2.134:20882:30882 
server.3=192.168.2.134:20883:30883

zoo2.cfg

sudo gedit zoo2.cfg

插入内容：

# 集群中的Follower服务器初始化连接服务器时能等待的最大心跳数（连接超时时长），默认为10
initLimit=10
syncLimit=5
# zookeeper存储文件的位置
dataDir=/home/hadoop/apache-zookeeper-3.7.0-bin/2.data
# zookeeper日志文件的位置
dataLogDir=/home/hadoop/apache-zookeeper-3.7.0-bin/2.logs
# zookeeper供客户端连接的端口，默认是2181
clientPort=2181
# 设置三个节点
server.1=192.168.2.134:20881:30881 
server.2=192.168.2.134:20882:30882 
server.3=192.168.2.134:20883:30883

zoo3.cfg

sudo gedit zoo3.cfg

输入内容:

initLimit=10
syncLimit=5
dataDir=/home/hadoop/apache-zookeeper-3.7.0-bin/2.data
dataLogDir=/home/hadoop/apache-zookeeper-3.7.0-bin/2.logs
clientPort=2181
server.1=192.168.2.134:20881:30881 
server.2=192.168.2.134:20882:30882 
server.3=192.168.2.134:20883:30883

2，建立数据和日志文件

进入安装目录

cd /home/hadoop/apache-zookeeper-3.7.0-bin

创建数据文件

mkdir 1.data 2.data 3.data

创建日志文件

mkdir 1.logs 2.logs 3.logs

3，启动服务并查看状态

先进入zookeeper安装目录的bin目录

cd cd/home/hadoop/apache-zookeeper-3.7.0-bin/bin

分别启zookeeper服务：

zkServer.sh start /home/hadoop/apache-zookeeper-3.7.0-bin/conf/zoo1.cfg
zkServer.sh start /home/hadoop/apache-zookeeper-3.7.0-bin/conf/zoo2.cfg
zkServer.sh start /home/hadoop/apache-zookeeper-3.7.0-bin/conf/zoo3.cfg

分别查看服务状态：

zkServer.sh status /home/hadoop/apache-zookeeper-3.7.0-bin/conf/zoo1.cfg
zkServer.sh status /home/hadoop/apache-zookeeper-3.7.0-bin/conf/zoo2.cfg
zkServer.sh status/home/hadoop/apache-zookeeper-3.7.0-bin/conf/zoo3.cfg
