一、Zookeeper的安裝
1.http://www-us.apache.org/dist/zookeeper/stable/下載Zookeeper安裝包，並將zookeeper-3.4.12.tar.gz復制到/home/jun下並解壓
[jun@master ~]$ cd zookeeper-3.4.12/ [jun@master zookeeper-3.4.12]$ ls -l total 1604 drwxr-xr-x. 2 jun jun 149 Mar 27 12:32 bin -rw-rw-r--. 1 jun jun 87945 Mar 27 12:32 build.xml drwxr-xr-x. 2 jun jun 77 Mar 27 12:32 conf drwxr-xr-x. 10 jun jun 130 Mar 27 12:32 contrib drwxr-xr-x. 2 jun jun 4096 Mar 27 12:37 dist-maven drwxr-xr-x. 6 jun jun 4096 Mar 27 12:32 docs -rw-rw-r--. 1 jun jun 1709 Mar 27 12:32 ivysettings.xml -rw-rw-r--. 1 jun jun 8197 Mar 27 12:32 ivy.xml drwxr-xr-x. 4 jun jun 4096 Mar 27 12:32 lib -rw-rw-r--. 1 jun jun 11938 Mar 27 12:32 LICENSE.txt -rw-rw-r--. 1 jun jun 3132 Mar 27 12:32 NOTICE.txt -rw-rw-r--. 1 jun jun 1585 Mar 27 12:32 README.md -rw-rw-r--. 1 jun jun 1770 Mar 27 12:32 README_packaging.txt drwxr-xr-x. 5 jun jun 47Mar 27 12:32 recipes drwxr-xr-x. 8 jun jun 211 Mar 27 12:32 src -rw-rw-r--. 1 jun jun 1483366 Mar 27 12:32 zookeeper-3.4.12.jar -rw-rw-r--. 1 jun jun 819 Mar 27 12:36 zookeeper-3.4.12.jar.asc -rw-rw-r--. 1 jun jun 33 Mar 27 12:32 zookeeper-3.4.12.jar.md5 -rw-rw-r--. 1 jun jun 41 Mar 27 12:32 zookeeper-3.4.12.jar.sha1
2.使用gedit編輯zoo.cfg配置文件
[jun@master zookeeper-3.4.12]$ cp /home/jun/zookeeper-3.4.12/conf/zoo_sample.cfg /home/jun/zookeeper-3.4.12/conf/zoo.cfg [jun@master zookeeper-3.4.12]$ gedit /home/jun/zookeeper-3.4.12/conf/zoo.cfg
將下面的配置增加到最後面，配置的意思是“服務器編號、服務器地址、LF通信端口（Leader與Follower）、選舉端口”
server.1=master:2888:3888 server.2=slave0:2888:3888 server.3=slave1:2888:3888
3.創建節點標誌文件
由於在zoo.cfg當中配置了三臺服務器，每一臺服務器本地也需要一個myid文件，裏面包含服務器的ID號，需要在三臺機器上都創建myid文件。以master為例：
首先遞歸創建目錄（-p）
[jun@master zookeeper-3.4.12]$ mkdir -p /tmp/zookeeper [jun@master zookeeper-3.4.12]$ gedit /tmp/zookeeper/myid
然後新建myid文件並輸入對應的id號，只輸入一個1即可。
[jun@master zookeeper-3.4.12]$ cat /tmp/zookeeper/myid 1
另外兩臺機器同理。
4.將Zookeeper安裝文件從master復制到slave上（-r的意思是拷貝所有的文件和文件夾）
[jun@master zookeeper-3.4.12]$ scp -r /home/jun/zookeeper-3.4.12/ slave0:~ [jun@master zookeeper-3.4.12]$ scp -r /home/jun/zookeeper-3.4.12/ slave1:~
5.Zookeeper集群的啟動
（1）需要在三個節點上分別執行啟動操作
[jun@master zookeeper-3.4.12]$ /home/jun/zookeeper-3.4.12/bin/zkServer.sh start ZooKeeper JMX enabled by default Using config: /home/jun/zookeeper-3.4.12/bin/../conf/zoo.cfg Starting zookeeper ... STARTED
[jun@slave0 ~]$ /home/jun/zookeeper-3.4.12/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/jun/zookeeper-3.4.12/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[jun@slave1 ~]$ /home/jun/zookeeper-3.4.12/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/jun/zookeeper-3.4.12/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
（2）至少啟動兩臺服務器後，集群才會開始選舉leader節點，可以在三臺服務器上分別查看集群的狀態，可以看到slave0節點是leader節點。
[jun@master ~]$ /home/jun/zookeeper-3.4.12/bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /home/jun/zookeeper-3.4.12/bin/../conf/zoo.cfg Mode: follower [jun@slave0 ~]$ /home/jun/zookeeper-3.4.12/bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /home/jun/zookeeper-3.4.12/bin/../conf/zoo.cfg Mode: leader [jun@slave1 ~]$ /home/jun/zookeeper-3.4.12/bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /home/jun/zookeeper-3.4.12/bin/../conf/zoo.cfg Mode: follower
（3）Zookeeper客戶端交互式操作
[jun@master ~]$ /home/jun/zookeeper-3.4.12/bin/zkCli.sh -server master:2181 Connecting to master:2181 2018-07-23 11:40:29,091 [myid:] - INFO [main:Environment@100] - Client environment:zookeeper.version=3.4.12-e5259e437540f349646870ea94dc2658c4e44b3b, built on 03/27/2018 03:55 GMT 2018-07-23 11:40:29,093 [myid:] - INFO [main:Environment@100] - Client environment:host.name=master 2018-07-23 11:40:29,093 [myid:] - INFO [main:Environment@100] - Client environment:java.version=1.8.0_171 2018-07-23 11:40:29,095 [myid:] - INFO [main:Environment@100] - Client environment:java.vendor=Oracle Corporation 2018-07-23 11:40:29,095 [myid:] - INFO [main:Environment@100] - Client environment:java.home=/usr/java/jdk1.8.0_171/jre 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:java.class.path=/home/jun/zookeeper-3.4.12/bin/../build/classes:/home/jun/zookeeper-3.4.12/bin/../build/lib/*.jar:/home/jun/zookeeper-3.4.12/bin/../lib/slf4j-log4j12-1.7.25.jar:/home/jun/zookeeper-3.4.12/bin/../lib/slf4j-api-1.7.25.jar:/home/jun/zookeeper-3.4.12/bin/../lib/netty-3.10.6.Final.jar:/home/jun/zookeeper-3.4.12/bin/../lib/log4j-1.2.17.jar:/home/jun/zookeeper-3.4.12/bin/../lib/jline-0.9.94.jar:/home/jun/zookeeper-3.4.12/bin/../lib/audience-annotations-0.5.0.jar:/home/jun/zookeeper-3.4.12/bin/../zookeeper-3.4.12.jar:/home/jun/zookeeper-3.4.12/bin/../src/java/lib/*.jar:/home/jun/zookeeper-3.4.12/bin/../conf: 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:java.library.path=/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:java.io.tmpdir=/tmp 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:java.compiler=<NA> 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:os.name=Linux 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:os.arch=amd64 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:os.version=3.10.0-862.el7.x86_64 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:user.name=jun 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:user.home=/home/jun 2018-07-23 11:40:29,096 [myid:] - INFO [main:Environment@100] - Client environment:user.dir=/home/jun 2018-07-23 11:40:29,097 [myid:] - INFO [main:ZooKeeper@441] - Initiating client connection, connectString=master:2181 sessionTimeout=30000 watcher=org.apache.zookeeper.ZooKeeperMain$MyWatcher@799f7e29 Welcome to ZooKeeper! 2018-07-23 11:40:29,117 [myid:] - INFO [main-SendThread(master:2181):ClientCnxn$SendThread@1028] - Opening socket connection to server master/192.168.1.100:2181.
