zookeeper集群搭建

zookeeper集群搭建過程小記

zookeeper集群搭建相對來說比較簡單和容易實現。

環境：阿里雲主機

系統:centos7.2

zookeeper:zookeeper-3.4.6.tar.gz

jdk:jdk1.8.0_45

wget  --no-check-certificate

三，修改配置

# cd zookeeper/conf

# cp zoo_sample.cfg zoo.cfg
# vi zoo.cfg

# 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/hadoop/data/zookeeper
# 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
...server.1=hadoop001:2888:3888
server.2=hadoop002:2888:3888
server.3=hadoop003:2888:3888

# touch data/myid

# echo 1 > data/myid

六，建立myid檔案

[hadoop@hadoop002 zookeeper]# echo 2 > data/myid

[hadoop@hadoop003 zookeeper]# echo 3 > data/myid

七，匯入個人環境變數

export path=$path:$zookeeper_home/bin

驗證：

[hadoop@hadoop001 ~]#source .bash_profile

[hadoop@hadoop001 ~]$ which zkserver.sh
[hadoop@hadoop001 ~]$ zkserver.sh start
[hadoop@hadoop001 ~]$ zkserver.sh status
jmx enabled by default
mode: follower

zookeeper集群搭建

接觸zookeeper集群已有很長很長一段時間了，zookeeper在專案中的使用相當的頻繁，如dubb服務 amq集群 大資料領域hadoop等。zookeeper的集群建立非常簡單，一直想寫一篇文章來對集群使用的介紹，但一直沒能抽出空，今天正好閒來無事，就重新實踐一遍來整理記錄，下文是基本的集群...
