Java连接Zookeeper
一、配置zk环境
- 本人使用的是虚拟机，创建了两台linux服务器（安装过程百度上很多）
- 准备zk的安装包，zookeeper-3.4.10.tar.gz，可在Apache官网下载，这里我提供了一个百度云的https://pan.baidu.com/s/15icVROSKpgwUzqzpHW6Rbg 密码dgnp
- 安装过程
- 环境准备：安装JDK，配置Hosts，配置Hostname、关闭防火墙
- $ZOOKEEPER = /home/zookeeper_application/zookeeper-3.4.10
- tar -xvzf zookeeper-3.4.10.tar.gz目录为/home/zookeeper_application/zookeeper-3.4.10
- cd 到zookeeper-3.4.10，mkdir data 创建data文件夹，cd 到data，touch myid 创建myid文件，vi myid myid存server的id，可以是1，2，3…，必须唯一
- 创建$ZOOKEEPER/conf/zoo.cfg
修改zoo.cfg，增加如下： - dataDir=/home/zookeeper_application/zookeeper-3.4.10/data
clientPort=2181
initLimit=10
syncLimit=5
tickTime=2000
server.1=master:2888:3888 - 其中server.X代表组成整个服务的机器，当服务启动时，会在数据目录下查找这个文件myid,这个文件中存有服务器的号码。
- 配置/etc/profile：
- export ZOOKEEPER_HOME=/home/zookeeper_application/zookeeper-3.4.10
- export PATH=$PATH:/usr/local/jdk1.7/bin:$ZOOKEEPER_HOME/bin
- 同样配置另外一台服务器，myid为2
- 启动/状态/停止 在bin目录下 zkServer.sh start|status|stop
java部分
- 创建zk.properties
