zookeeper配置

她人

，使用环境 centos6.4
[iyunv@wang zookeeper-3.3.6]# uname -r
2.6.32-358.el6.x86_64
slave主机为
10.10.54.25
10.10.54.26
2,下载软件并安装
zookeeper-3.3.6.tar.bz2
jdk-7u51-linux-x64.rpm    //java环境
nc.x86_64                //监听端口
yum install nc.x86_64   
rpm -ivh jdk-7u51-linux-x64.rpm  
安装 zookeeper软件
  tar -jxvf zookeeper-3.3.6.tar.bz2
  [iyunv@wang home]# cd zookeeper-3.3.6
  编辑配置文件
  [iyunv@wang 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.
dataDir=/home/zookeeper-3.3.6/zookeeperdir/zookeeper-data
dataLogDir=/home/zookeeper-3.3.6/zookeeperdir/zookeeper-logs


# the port at which the clients will connect
clientPort=2181


server.1=slave-01:2888:3888
server.2=slave-02:2888:3888
#server.3=slave-03.1:2888:3888
  3,创建配置文件
   mkdir /home/zookeeper-3.3.6/zookeeperdir/zookeeper-data
   mkdir /home/zookeeper-3.3.6/zookeeperdir/zookeeper-logs
  4,修改配置文件/ect/hosts,实现ip解析
    添加
    10.10.54.25 slave-01
    10.10.54.26 slave-02
  5,远程配置剩余主机
  [iyunv@wang home]# scp -r zookeeper-3.3.6 root@10.10.54.25:/home
  [iyunv@wang zookeeper-3.3.6]# scp -r /etc/hosts root@10.10.54.25:/etc/
  6,启动zooleeper并查看zookeeper的状态
[iyunv@wang home]# /home/zookeeper-3.3.6/bin/zkServer.sh restart
  JMX enabled by default
  Using config: /home/zookeeper-3.3.6/bin/../conf/zoo.cfg
  JMX enabled by default
  Using config: /home/zookeeper-3.3.6/bin/../conf/zoo.cfg
  Stopping zookeeper ... STOPPED
  JMX enabled by default
  Using config: /home/zookeeper-3.3.6/bin/../conf/zoo.cfg
  Starting zookeeper ... STARTED
  [iyunv@wang home]# /home/zookeeper-3.3.6/bin/zkServer.sh status
  JMX enabled by default
  Using config: /home/zookeeper-3.3.6/bin/../conf/zoo.cfg
  Mode: follower
  7，错误总结
   Cannot open channel to 3 at election address
   原因ip不能正常解析
   #server.2=slave-02.1:2888:3888
   改为 server.2=slave-02:2888:3888
   nohup --java
   缺少java支持
   安装java jdk
   rpm -ivh jdk-7u51-linux-x64.rpm
