zookeeper安裝與配置

目錄

一、建立并進入zookeeper的安裝目錄

二、下載下傳并解壓縮zookeeper-3.4.9.tar.gz

三、zookeeper配置

四、啟動zookeeper服務

五、叢集配置

一、建立并進入zookeeper的安裝目錄

mkdir -p /usr/local/services/zookeeper
           

cd /usr/local/services/zookeeper
           

二、下載下傳并解壓縮zookeeper-3.4.9.tar.gz

wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz


tar -zxvf zookeeper-3.4.9.tar.gz
           

三、zookeeper配置

1. 進入zookeeper目錄下的conf目錄
2. 将zoo_sample.cfg檔案複制一份,并重命名為zoo.cfg

cp zoo_sample.cfg zoo.cfg
           

1. 編輯配置檔案zoo.cfg

vim zoo.cfg


# The number of milliseconds of each tick

# zookeeper定義的基準時間間隔,機關是毫秒

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.

# 資料檔案夾

dataDir=/usr/local/service/zookeeper/zookeeper-3.4.9/data

#日志檔案夾

dataLogDir=/usr/local/service/zookeeper/zookeeper-3.4.9/logs

# the port at which the clients will connect

#用戶端通路zookeeper的端口号

clientPort=2181

# the maximum number of client connections.
           

1. wq!儲存zoo.cfg檔案後,進入到bin目錄中，編輯系統配置檔案profile

vim /etc/profile
           

在檔案尾部追加如下内容

export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/

export PATH=$ZOOKEEPER_HOME/bin:$PATH

export PATH
           

使配置立即生效

source /etc/profile
           

四、啟動zookeeper服務

啟動zookeeper服務：zkServer.sh start

檢視zookeeper狀态：zkServer.sh status

關閉zookeeper服務：zkServer.sh stop

重新開機zookeeper服務：zkServer.sh restart
           

五、叢集配置

1. 編輯/etc/hosts，配置好位址和主機名映射關系，例如

192.168.100.1 server1

192.168.100.2 server2

192.168.100.3 server3
           

1. 配置檔案

cp zoo_sample.cfg zk1.cfg

cp zoo_sample.cfg zk2.cfg

cp zoo_sample.cfg zk3.cfg
           

1. 配置說明

格式：server.A=B:C:D

A表示這台伺服器的編号ID，是一個數字

B表示伺服器的IP位址或域名

C表示這台伺服器與叢集中的Leader交換資訊時使用的端口

D表示執行選舉Leader伺服器時互相通信的端口
           

1. zk1.cfg

#指定資料檔案夾和日志檔案夾

dataDir= /usr/local/service/zookeeper/zookeeper-3.4.9/data/zk1

dataLogDir= /usr/local/service/zookeeper/zookeeper-3.4.9/logs/zk1

#指定端口

clientPort=2181

#server.序号= (主機名, 心跳端口、資料端口)

server.1= 192.168.100.1:2888:3888

server.2= 192.168.100.2:2888:3888

server.3= 192.168.100.3:2888:3888
           

1. zk2.cfg

#指定資料檔案夾和日志檔案夾

dataDir=/usr/local/service/zookeeper/zookeeper-3.4.9/data/zk2

dataLogDir=/usr/local/service/zookeeper/zookeeper-3.4.9/logs/zk2

#指定端口

clientPort=2181

#server.序号= (主機名, 心跳端口、資料端口)

server.1= 192.168.100.1:2888:3888

server.2= 192.168.100.2:2888:3888

server.3= 192.168.100.3:2888:3888
           

1. zk3.cfg

dataDir=/usr/local/service/zookeeper/zookeeper-3.4.9/data/zk3

dataLogDir=/usr/local/service/zookeeper/zookeeper-3.4.9/logs/zk3

#指定端口

clientPort=2181

#server.序号= (主機名, 心跳端口、資料端口)

server.1= 192.168.100.1:2888:3888

server.2= 192.168.100.2:2888:3888

server.3= 192.168.100.3:2888:3888
           

1. 在每個檔案夾中建立一個myid檔案，内容為其對應的id号

echo "1" > /usr/local/service/zookeeper/zookeeper-3.4.9/data/zk1/myid

echo "2" > /usr/local/service/zookeeper/zookeeper-3.4.9/data/zk2/myid

echo "3" > /usr/local/service/zookeeper/zookeeper-3.4.9/data/zk3/myid
           

1. 啟動服務

zkServer.sh start zk1.cfg

zkServer.sh start zk2.cfg

zkServer.sh start zk3.cfg
