zookeeper叢集安裝部署

一、準備工作

1.三台伺服器：master、slave1、slave2

2.三台伺服器安裝了java環境

3.在官網下載下傳zookeeper-3.4.10.tar.gz

二、安裝zookeeper叢集

1.分别修改三台伺服器的hosts檔案：

[[email protected] ~]# vim /etc/hosts
           

添加如下内容：

192.168.100.1     master
192.168.100.2     slave1
192.168.100.3     slave2
           

儲存退出，并重新開機三台伺服器。

2.解壓zookeeper

[[email protected] ~]# tar -zxvf zookeeper-3.4.10.tar.gz -C /home
           

3.修改相應配置

①進入解壓後的檔案夾下，并建立data和logs兩個檔案夾

[[email protected] ~]# cd /home/zookeeper-3.4.10
[[email protected] zookeeper-3.4.10]# mkdir data
[[email protected] zookeeper-3.4.10]# mkdir logs
           

②進入conf目錄下，将zoo_sample.cfg複制并重命名為zoo.cfg

[[email protected] zookeeper-3.4.10]# cd conf
[[email protected] conf]# cp zoo_sample.cfg zoo.cfg
           

③修改zoo.cfg檔案配置

[[email protected] conf]# vim zoo.cfg
           

添加如下内容： 

# 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=/home/zookeeper-3.4.10/data
dataLogDir=/home/zookeeper-3.4.10/logs
# 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.0=master:2888:3888
server.1=slave1:2888:3888
server.2=slave2:2888:3888
           

④建立myid檔案并修改

進入剛剛建立的data檔案夾下，建立myid檔案，并添加内容

[[email protected] conf]# cd /home/zookeeper-3.4.10/data

[[email protected] conf]# vim myid
           

添加如下内容：

4.在另外兩台機器上也同樣進行1、2、3的步驟，但是每個機器上myid的内容必須不一樣。我的設定為：master的myid為0；slave1的myid為1；slave2的myid為2。

5.修改profile檔案

[[email protected] conf]# vim /etc/profile
           

添加如下内容：

#zookeeper
export ZK_HOME=/home/zookeeper-3.4.10
export PATH=$ZK_HOME/bin:$PATH
           

使修改生效：

[[email protected] conf]# source /etc/profile
           

6.啟動zookeeper以及檢視狀态

進入到zookeeper的bin目錄下

啟動(需要在三個節點分别啟動)：

[[email protected] bin]# ./zkServer.sh start
           

檢視狀态:

[[email protected] bin]# ./zkServer.sh status
