zookeeper3.5.7安装部署

目录

 1.安装前准备

2.安装zookeeper

3. 修改环境变量

4.配置 zoo.cfg

5. 集成 ZooKeeper 到Hadoop

6. 启动 ZooKeeper

• 注意安装前请确认已经成功安装了Hadoop

• 安装前请关闭Spark和Hadoop相关进程（请先关闭Spark，再关闭Hadoop）

• ZooKeeper 可以从官方网站下载：Zookeeper官网

 1.安装前准备

建立三个文件夹用于存储大数据软件、安装包、日志数据

mkdir -p /export/server

mkdir -p /export/software

mkdir -p /export/data

2.安装zookeeper

cd /export/software/
下载安装包 wget https://archive.apache.org/dist/zookeeper/zookeeper-3.5.7/apache-zookeeper-3.5.7-bin.tar.gz

进入server目录下
cd /export/server

tar -zxvf /export/software/apache-zookeeper-3.5.7-bin.tar.gz 

3. 修改环境变量

vim /etc/profile

#zookeeper

export PATH=$PATH:/export/servers/apache-zookeeper-3.5.7-bin/bin

export ZOOKEEPER_HOME=/export/servers/apache-zookeeper-3.5.7-bin
source  /etc/profile

4.配置 zoo.cfg

• 进入 ZooKeeper 的 conf 目录，并将 zoo_sample.cfg 文件重命名为 zoo.cfg ​​​​​​​

cp $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg

建立一个zkdata文件夹用于存放zookeeper日志文件

mkdir  -p /export/data/zookeeper/zkdata/
 

vim $ZOOKEEPER_HOME/conf/zoo.cfg

• 修改相关设置，注意此处设置 dataDir 和 dataLogDir

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/export/data/zookeeper/zkdata/
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=hadoop01:2888:3888
server.2=hadoop02:2888:3888
server.3=hadoop03:2888:3888

• 创建对应的文件夹

mkdir -p $ZOOKEEPER_HOME/{data,logs}
 ls $ZOOKEEPER_HOME/

5. 集成 ZooKeeper 到Hadoop

修改 yarn-site.xml文件将 zookeeper参数写入

 vim $HADOOP_HOME/etc/hadoop/yarn-site.xml

<property>
                <name>ha.zookeeper.quorum</name>
                <value>lhadoop01:2181</value>
        </property>

6. 启动 ZooKeeper

• 运行以下命令以启动 ZooKeeper：

$ZOOKEEPER_HOME/bin/zkServer.sh start

• jps检查ZooKeeper是否启动，应该有QuorumPeerMain进程

这样就已经安装zookeeper
