tickTime@H_404_9@
- CS通信心跳时间
- 心跳间隔,单位是毫秒,系统默认是2000毫秒,也就是间隔两秒心跳一次
tickTime的意义@H_404_9@
initLimit@H_404_9@
synclimit@H_404_9@
dataDir@H_404_9@
- 该属性对应的目录是用来存放myid信息跟一些版本,日志,跟服务器唯一的ID信息等
- the directory where the snapshot is stored. do not use /tmp for storage, /tmp here is just example sakes.
不要使用/tmp来做存储快照的目录,/tmp这只是一个案例@H_404_9@

配置结束后启动
cd bin ./zkServer.sh start
集群信息的配置@H_404_9@
格式:service.N = YYY:A:B
- N:代表服务器编号(也就是myid里面的值)
- YYY:服务器地址
- A:表示 Flower 跟 leader的通信端口,leader接受write请求(默认2888)
- B:表示 选举端口,leader挂掉以后,使用该端口执行选举操作(默认是3888)
server.1=node01:2888:3888 server.2=node02:2888:3888 server.3=node03:2888:3888
server的myid配置@H_404_9@
在每个结点server指定的dataDir目录下创建myid文件并写入对应的服务器编号
第一个结点,填入1,第二个结点,填入2,依此类推
clientPort@H_404_9@
- 客户端连接的接口,客户端连接zookeeper服务器的端口
- zookeeper会监听这个端口,接收客户端的请求访问
- 这个端口默认是2181
导入环境变量@H_404_9@
打开文件/etc/profile,填入自己的zooke安装目录
export ZOOKEEPER_HOME=/root/apache-zookeeper-3.6.2-bin export PATH=$PATH:$ZOOKEEPER_HOME/bin
使能
source /etc/profile
使用客户端管理节点
创建节点并添加数据@H_404_9@
获取节点数据@H_404_9@
create -e 创建临时节点
create -s 持久序列
