Zookeeper笔记（安装）

北风留影

　　3台服务器集群。
　　一：分别在这3台服务器上安装jdk，我采取的是jdk1.8。
　　二：主机名称到IP地址映射配置
　　三：修改ZooKeeper配置文件
　　下载zookeeper-3.4.6.tar.gz，解压到/opt 目录。
　　创建 ZooKeeper 配置文件 zookeeper-3.4.6/conf/zoo.cfg，vi
conf/zoo.cfg。添加以下内容


　　tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
dataLogDir=/data/zookeeper/logs
clientPort=2181
server.1=host61:2888:3888
server.2=host1:2888:3888
server.3=host2:2888:3888ZooKeeper
的数据目录指定在 /data/zookeeper/data ，你也可以使用其他目录，通过下面命令进行创建该目录：
　　$ mkdir /data/zookeeper/data -p
　　


　　然后，初始化 myid ，三个节点编号依次为 1，2，3 ，在其余节点上分别执行命令（注意修改编号）。

$ echo "1" >/data/zookeeper/data/myid

然后，在第二个和第三个节点上依次重复上面的操作。这样第一个节点中 myid 内容为1，第二个节点为2，第三个节点为3。



最后，启动 ZooKeeper 集群，在每个节点上分别启动 ZooKeeper 服务：



$ cd /opt

$ sh zookeeper-3.4.5/bin/zkServer.sh start

可以查看 ZooKeeper 集群的状态，保证集群启动没有问题：

[iyunv@192.168.56.121 opt]# sh zookeeper-3.4.5/bin/zkServer.sh status

JMX enabled by default

Using config: /opt/zookeeper-3.4.5/bin/../conf/zoo.cfg

Mode: follower




　　查看Zookeeper.out 。出现以下java.net.ConnectException:
拒绝连接。。这不用管，我启动的顺序是slave-01>slave-02>slave-03，由于ZooKeeper集群启动的时候，每个结点都试图去连接集群中的其它结点，先启动的肯定连不上后面还没启动的，所以上面日志前面部分的异常是可以忽略的。通过后面部分可以看到，集群在选出一个Leader后，最后稳定了。2015-04-15 18:30:15,704 [myid:] - INFO  [main:QuorumPeerConfig@103] - Reading configuration from: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
