搭建zookeeper集群

三台服务器：先设置hosts
10.0.0.231  node1
10.0.0.232  node2
10.0.0.233  node3

1：解压 zookeeper-3.4.10.tar.gz 到/usr/local
2：创建软链接 到/usr/local/zk
3：复制zk/conf/zoo_sample.cfg 为zoo.cfg
4：修改zoo.cfg内容为
tickTime=2000

initLimit=10

syncLimit=5

dataDir=/opt/zookeeper

clientPort=2181

server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888

5：在/opt/下创建zookeeper文件夹
6：在/opt/zookeeper下创建myid文件，内容为1

10.0.0.231  myid内容为1
10.0.0.232  myid内容为2
10.0.0.233  myid内容为3

zkServer.sh start

1) 切换到/etc/rc.d/init.d/目录下
2) 创建zookeeper文件：touch zookeeper
3) 更新权限：chmod +x zookeeper
4) 编辑文件，在zookeeper里面输入如下内容
   #!/bin/bash
   #chkconfig:2345 20 90
   #description:zookeeper
   #processname:zookeeper
    export JAVA_HOME=/usr/local/jdk
    export PATH=$JAVA_HOME/bin:$PATH
    case $1 in
          start) /usr/local/zk/bin/zkServer.sh start;;
          stop) /usr/local/zk/bin/zkServer.sh stop;;
          status) /usr/local/zk/bin/zkServer.sh status;;
          restart) /usr/local/zk/bin/zkServer.sh restart;;
          *)  echo "require start|stop|status|restart" ;;
    esac


5) chkconfig zookeeper on
6) 验证
chkconfig --add zookeeper  把zookeeper添加到开机启动里面
chkconfig --list zookeeper 查看是否添加的zookeeper到开机启动
