Zookeeper集群搭建-Windows

一、软件版本

zookeeper官网

apache-zookeeper-3.7.0-bin.tar.gz下载地址

==操作系统：Win10 20H2==

二、依赖安装：JDK8

参考：Cassandra 3.11.10 集群搭建-Windows中JDK安装。

三、单机部署

1. 解压apache-zookeeper-3.7.0-bin.tar.gz放置于任意盘中

2. 设置环境变量

   1)ZOOKEEPER_HOME

2)bin

3)环境变量验证

win+r 输入cmd打开控制台，任意路径下输入命令：zkServer。

3. 配置zookeeper配置文件

   1)zookeeper配置文件路径

   D:\software\apache-zookeeper-3.7.0-bin\conf

​ 实际运行时，zookeeper加载名为zoo.cfg的配置文件，这时仅需赋值zoo_sample.cfg文件，并重命名为zoo.cfg。

​ 2)zookeeper配置文件内容请参考：

配置项	含义
tickTime	ZK中的一个时间单元。ZK中所有时间都是以这个时间单元为基础，进行整数倍配置的。例如，session的最小超时时间是2*tickTime。
initLimit	初始化集群时集群节点同步超时时间, 默认是10个tickTime, 也即20s
syncLimit	集群在运行过程中同步数据超时时间, 默认5个tickTime
dataDir	默认数据存储位置
clientPort	zookeeper服务监听端口号
maxClientCnxns	连接池连接数量
autopurge.snapRetainCount	zookeeper是运行在内存中的, 因此与Redis类似, 他也是使用快照进行持久化. 这里的snapRetainCount是指有多少个快照就会将快照进行合并
autopurge.purgeInterval	同样是快照合并的配置, 这里指的是在多长时间内, 如果有snapRetainCount个快照, 进行合并

​ 3)zookeeper配置

​ 这里仅配置了dataDir项:默认数据存储位置：dataDir=D:\software\apache-zookeeper-3.7.0-bin\data

4. 启动zookeeper&验证

   使用命令：zkServer 启用zookeeper

新启cmd，使用命令zkCli -server 127.0.0.1:2181

四、集群搭建：单机多进程（单IP多端口）

1. 这里无需设置环境变量，可把单机时设置的环境变量删除！
2. 拷贝出3个apache-zookeeper-3.7.0-bin并依次重命名

3. 依次修改配置文件

   1)apache-zookeeper-3.7.0-bin-0

   创建默认数据存储位置文件夹，依次修改配置项：

dataDir=D:\software\zookeeper\apache-zookeeper-3.7.0-bin-0\data #此处需修改，无文件夹则需创建，保证文件路径的格式：\\

集群点：

server.0=127.0.0.1:8880:7770 #服务1
server.1=127.0.0.1:8881:7771 #服务2
server.2=127.0.0.1:8882:7772 #服务3

#格式： server.A = B:C:D
#A:是一个数字，表示第几号服务器
#B:服务器IP地址
#C:是一个端口号，用来集群成员的信息交换,表示这个服务器与集群中的leader服务器交换信息的端口
#D:是在leader挂掉时专门用来进行选举leader所用的端口

所需修改配置项如下：

clientPort=2180
dataDir=D:\\software\\zookeeper\\apache-zookeeper-3.7.0-bin-0\\data	 #此处需修改，无文件
server.0=127.0.0.1:8880:7770		#服务1
server.1=127.0.0.1:8881:7771		#服务2
server.2=127.0.0.1:8882:7772		#服务3
复制代码

总配置文件如下：

# 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.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=D:\\software\\zookeeper\\apache-zookeeper-3.7.0-bin-0\\data	 #此处需修改，无文件夹则需创建，保证文件路径的格式：\\
# the port at which the clients will connect
clientPort=2180
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

2)apache-zookeeper-3.7.0-bin-1

所需修改配置项如下：

clientPort=2181
dataDir=D:\\software\\zookeeper\\apache-zookeeper-3.7.0-bin-1\\data
server.0=127.0.0.1:8880:7770		#服务1
server.1=127.0.0.1:8881:7771		#服务2

server.1=127.0.0.1:8881:7771
server.2=127.0.0.1:8882:7772
复制代码

3)apache-zookeeper-3.7.0-bin-2

所需修改配置项如下：

clientPort=2182
dataDir=D:\\software\\zookeeper\\apache-zookeeper-3.7.0-bin-2\\data
server.0=127.0.0.1:8880:7770		#服务1
server.1=127.0.0.1:8881:7771		#服务2
server.2=127.0.0.1:8882:7772		#服务3
复制代码

总配置文件如下：

# The number of milliseconds of each tick

# The number of ticks that can pass between 
# sending a request and getting an acknowledgement

server.1=127.0.0.1:8881:7771		#服务2
server.2=127.0.0.1:8882:7772		#服务3

4. 添加myid文件

​ 保证每个apache-zookeeper-3.7.0-bin中的配置文件中的dataDir项的文件夹中对应有myid文件，且myid文件中存有对应的id号。

​ apache-zookeeper-3.7.0-bin-0为服务0，则在==dataDir=D:\software\zookeeper\apache-zookeeper-3.7.0-bin-0\data==路径下新增myid文件，并在其写入0。

​ apache-zookeeper-3.7.0-bin-1为服务1，则在==dataDir=D:\software\zookeeper\apache-zookeeper-3.7.0-bin-1\data==路径下新增myid文件，并在其写入1。

​ apache-zookeeper-3.7.0-bin-2为服务2，则在==dataDir=D:\software\zookeeper\apache-zookeeper-3.7.0-bin-2\data==路径下新增myid文件，并在其写入2。

3. 依次启动服务

   由于未配置环境变量，则需cmd中cd到每个zookeeper文件夹下的bin目录中执行命令zkServer。

五、集群搭建：多机

方法同==四、集群搭建：单机多进程（单IP多端口）==，但需修改配置文件中的集群配置：

server.0=192.168.2.207:8880:7770		#服务1
server.1=192.168.2.203:8880:7770		#服务2
server.2=192.168.79.128:8880:7770		#服务3
