zookeeper3.4.8僞集羣安裝java

軟件包：zookeeper-3.4.8.tar.gzlinux

Java包：jdk-8u77-linux-x64.gzapache

平臺：centos6.2 64位vim

在一臺機器上安裝3個僞zookeeper集羣centos

server.1=localhost:2287:3390api

server.2=localhost:2288:3388服務器

server.3=localhost:2289:3389session

安裝過程：socket

首先安裝jdk8ide

# mkdir /usr/lib/jdk（建立jdk安裝目錄）

# tar xf jdk-8u77-linux-x64.gz -C /usr/lib/jdk（解壓jdk包）

# vim /etc/profile（設置環境變量）

在profile末尾添加下面環境變量

export JAVA_HOME=/usr/lib/jdk/jdk1.8.0_77

export JRE_HOME=/usr/lib/jdk/jdk1.8.0_77/jre

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

export CLASSPATH=$CLASSPATH:.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

# source /etc/profile（讓環境變量生效）

# java -version（查看java版本）

java version "1.8.0_77"

Java(TM) SE Runtime Environment (build 1.8.0_77-b03)

Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)

Jdk8安裝成功後安裝zookeeper

此處在同一臺機器上模擬三個zookeeper集羣節點，即叫僞集羣

在真實環境部署時，只用把zoo.cfg中的localhost替換成真實節點的ip地址便可。

# mkdir -pv /home/hadoop/{zookeeper-1,zookeeper-2,zookeeper-3} （建立目錄）

# mkdir -pv /home/hadoop/tmp/{zk1/data,zk1/log,zk2/data,zk2/log,zk3/data,zk3/log} （建立目錄）

#tar xf zookeeper-3.4.8.tar.gz （解壓zookeeper包）

把解壓的文件複製到不一樣的目錄中

#cp -r zookeeper-3.4.8/* /home/hadoop/zookeeper-1/

# cd /home/hadoop/zookeeper-1/conf/

#vim zoo.cfg （建立配置文件）

在zoo.cfg添加以下內容

clientPort=2181 （客戶端鏈接服務器的端口號）

tickTime=2000 （服務器心跳時間ms）

initLimit=10 （投票選舉新leader的初始化時間）

syncLimit=5 （leader與follower最大響應時間）

dataDir=/home/hadoop/tmp/zk1/data （數據存放目錄）

dataLogDir=/home/hadoop/tmp/zk1/log （日誌存放目錄）

server.1=localhost:2287:3390

server.2=localhost:2288:3388

server.3=localhost:2289:3389

# cd /home/hadoop/zookeeper-2/conf/

#vim zoo.cfg

clientPort=2182

tickTime=2000

initLimit=10

syncLimit=5

dataDir=/home/hadoop/tmp/zk2/data

dataLogDir=/home/hadoop/tmp/zk2/log

server.1=localhost:2287:3390

server.2=localhost:2288:3388

server.3=localhost:2289:3389

# cd /home/hadoop/zookeeper-3/conf/

#mv zoo_sample.cfg zoo.cfg

#vim zoo.cfg

clientPort=2183

tickTime=2000

initLimit=10

syncLimit=5

dataDir=/home/hadoop/tmp/zk3/data

dataLogDir=/home/hadoop/tmp/zk3/log

server.1=localhost:2287:3390

server.2=localhost:2288:3388

server.3=localhost:2289:3389

分別在zookeeper的數據目錄建立myid，myid的內容爲zoo.cfg配置文件中server.1中的1，2，或3

#echo 「1」 > /home/hadoop/tmp/zk1/data/myid
#echo 「2」 > /home/hadoop/tmp/zk2/data/myid

#echo 「3」 > /home/hadoop/tmp/zk3/data/myid

#/home/hadoop/zookeeper-1/bin/zkServer.sh start （啓動zookeeper）

#/home/hadoop/zookeeper-2/bin/zkServer.sh start

#/home/hadoop/zookeeper-3/bin/zkServer.sh start

# ss -tnl

0 50 *:2181 *:*

0 50 *:2182 *:*

0 50 *:2183 *:*

測試鏈接zookeeper

#/home/hadoop/zookeeper-1/bin/zkCli.sh -server localhost:2181

Connecting to localhost:2181
