1、安装包地址
http://www.apache.org/dyn/closer.cgi/zookeeper/
点击后找到地址http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.1-alpha/
所以地址安装包地址为
http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.1-alpha/zookeeper-3.5.1-alpha.tar.gz
右键 复制连接地址得到的。
2、下载安装
#wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.1-alpha/zookeeper-3.5.1-alpha.tar.gz
2.2 安装
# tar -zxvf zookeeper-3.5.1-alpha.tar.gz
2.3 把放到usr/local/ 目录去
# mv zookeeper-3.5.1-alpha /usr/local
2.4修改配置（/usr/local/zookeeper-3.5.1-alpha/conf/目录下）
先备份文件
# cp zoo_sample.cfg zoo.cfg
修改配置
dataDir=/usr/local/zookeeper-3.5.1
3、启动 zookeeper(在/usr/local/zookeeper-3.5.1/bin/下)
[root@iZ25av9xi4hZ bin]# ./zkServer.sh startZooKeeper JMX enabled by default/usr/bin/javaUsing config: /usr/local/zookeeper-3.5.1/bin/../conf/zoo.cfgStarting zookeeper ... STARTED[root@iZ25av9xi4hZ bin]#
启动成功了
3.1查看下状态
[root@iZ25av9xi4hZ bin]# ./zkServer.sh statusZooKeeper JMX enabled by default/usr/bin/javaUsing config: /usr/local/zookeeper-3.5.1/bin/../conf/zoo.cfgClient port found: 2181. Client address: localhost.Mode: standalone[root@iZ25av9xi4hZ bin]#
在日志看下（/usr/local/zookeeper-3.5.1-alpha/logs/目录下）
