安装Zookeeper

1.安装

1.上传安装包

zookeeper-3.4.10.tar.gz

2.解压安装包

1.  
   [root@hadoop01 software]# tar -zxvf zookeeper-3.4.10.tar.gz -C /opt/module/
2.  
   [root@hadoop01 software]# cd /opt/module/
3.  
   [root@hadoop01 module]# mv zookeeper-3.4.10/ zookeeper
4.  
   [root@hadoop01 conf]# cd /opt/module/zookeeper/conf

2.配置文件

1.修改zoo_sample.cfg名称

[root@hadoop01 conf]# mv zoo_sample.cfg zoo.cfg

2.创建一个存放zk数据的目录:

[root@hadoop01 zookeeper]# mkdir /opt/module/zookeeper/data

3.配置zoo.cfg 

1.  
   [root@hadoop01 zookeeper]# vim conf/zoo.cfg
2.  
    
3.  
   # The number of milliseconds of each tick
4.  
   tickTime=2000
5.  
   # The number of ticks that the initial
6.  
   # synchronization phase can take
7.  
   initLimit=10
8.  
   # The number of ticks that can pass between
9.  
   # sending a request and getting an acknowledgement
10.  
    syncLimit=5
11.  
    # the directory where the snapshot is stored.
12.  
    # do not use /tmp for storage, /tmp here is just
13.  
    # example sakes.
14.  
    dataDir=/opt/module/zookeeper/data
15.  
    # the port at which the clients will connect
16.  
    clientPort=2181
17.  
    # the maximum number of client connections.
18.  
    # increase this if you need to handle more clients
19.  
    #maxClientCnxns=60
20.  
    #
21.  
    # Be sure to read the maintenance section of the
22.  
    # administrator guide before turning on autopurge.
23.  
    #
24.  
    # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
25.  
    #
26.  
    # The number of snapshots to retain in dataDir
27.  
    #autopurge.snapRetainCount=3
28.  
    # Purge task interval in hours
29.  
    # Set to "0" to disable auto purge feature
30.  
    #autopurge.purgeInterval=1
31.  
    #配置集群的机器
32.  
    server.1=hadoop01:2888:3888
33.  
    server.2=hadoop02:2888:3888
34.  
    server.3=hadoop03:2888:3888

4.测试

1.  
   [root@hadoop01 data]# cd /opt/module/zookeeper/data/
2.  
   [root@hadoop01 data]# touch myid
3.  
   [root@hadoop01 data]# echo 1 > myid
4.  
   [root@hadoop01 data]# cat myid
5.  
   1

3.把集群文件同步到其它机器

1.同步文件

[root@hadoop01 zookeeper]# /root/bin/xsync /opt/module/zookeeper

2.写入

1.  
   [root@hadoop01 zookeeper]# cd /opt/module/zookeeper/data/
2.  
   [root@hadoop01 data]# cat myid
3.  
   1
4.  
   [root@hadoop02 data]# echo 2 > myid
5.  
   [root@hadoop02 data]# cat myid
6.  
   2
7.  
   [root@hadoop03 module]# cd /opt/module/zookeeper/data/
8.  
   [root@hadoop03 data]# echo 3 > myid
9.  
   [root@hadoop03 data]# cat myid
10.  
    3

4.集群的启动与关闭

1.  
   [root@hadoop01 data]# cd /opt/module/zookeeper/
2.  
   [root@hadoop02 data]# cd /opt/module/zookeeper/
3.  
   [root@hadoop03 data]# cd /opt/module/zookeeper/
4.  
   在三台机器中执行命令:
5.  
   # bin/zkServer.sh start ---启动命令
6.  
   # bin/zkServer.sh stop ---停止命令
7.  
   # bin/zkServer.sh status ---查看状态命令

5.检查集群启动的状态

1.  
   [root@hadoop01 zookeeper]# bin/zkServer.sh status
2.  
   ZooKeeper JMX enabled by default
3.  
   Using config: /opt/module/zookeeper/bin/../conf/zoo.cfg
4.  
   Mode: follower
5.  
    
6.  
   [root@hadoop02 zookeeper]# bin/zkServer.sh status
7.  
   ZooKeeper JMX enabled by default
8.  
   Using config: /opt/module/zookeeper/bin/../conf/zoo.cfg
9.  
   Mode: leader
10.  
     
11.  
    [root@hadoop03 zookeeper]# bin/zkServer.sh status
12.  
    ZooKeeper JMX enabled by default
13.  
    Using config: /opt/module/zookeeper/bin/../conf/zoo.cfg
14.  
    Mode: follower
