在三臺Centos或Windows中部署三臺Zookeeper集羣配置

1、安裝包

　　一、下載最新版（3.4.13）：https://archive.apache.org/dist/zookeeper/  下載https://archive.apache.org/dist/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz解壓開便可。本文中解壓到/opt目錄下。

 

2、環境

　　一、三臺服務器IP分別爲：192.168.1.10四、192.168.1.10五、192.168.1.106

　　二、三臺的Zookeeper配置文件路徑都是：/opt/zookeeper/zookeeper-3.4.13/conf/zoo.cfg

 

3、配置集羣：

　　一、服務器192.168.1.104中：

　　（1）修改/opt/zookeeper/zookeeper-3.4.13/conf/zoo.cfg文件內容以下：

# 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=/opt/zookeeper/zkdata/data
dataLogDir=/opt/zookeeper/zkdata/log
# the port at which the clients will connect
clientPort=2181
# 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 server.104=0.0.0.0:2888:3888 server.105=192.168.6.105:2888:3888 server.106=192.168.6.106:2888:3888

　　（2）建立目錄並配置myid。

　　　　I、建立目錄：/opt/zookeeper/zkdata/data

　　　　II、建立文件：/opt/zookeeper/zkdata/data/myid ，內容爲"104"  ，或者使用命令快速生成：

echo 104>/opt/zookeeper/zkdata/data/myid

 

 

 

　　二、服務器192.168.1.105中：

　　（1）修改/opt/zookeeper/zookeeper-3.4.13/conf/zoo.cfg文件內容以下：

# 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=/opt/zookeeper/zkdata/data dataLogDir=/opt/zookeeper/zkdata/log # the port at which the clients will connect clientPort=2181 # 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 server.104=192.168.6.104:2888:3888 server.105=0.0.0.0:2888:3888 server.106=192.168.6.106:2888:3888

　　（2）建立目錄並配置myid。

　　　　I、建立目錄：/opt/zookeeper/zkdata/data

　　　　II、建立文件：/opt/zookeeper/zkdata/data/myid ，內容爲"105"  ，或者使用命令快速生成：

echo 105>/opt/zookeeper/zkdata/data/myid

 

 

 

 

 

　　三、服務器192.168.1.106中：

　　（1）修改/opt/zookeeper/zookeeper-3.4.13/conf/zoo.cfg文件內容以下：

# 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=/opt/zookeeper/zkdata/data
dataLogDir=/opt/zookeeper/zkdata/log
# the port at which the clients will connect
clientPort=2181
# 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

server.104=192.168.6.104:2888:3888
server.105=192.168.6.105:2888:3888
server.106=0.0.0.0:2888:3888

　　（2）建立目錄並配置myid。

　　　　I、建立目錄：/opt/zookeeper/zkdata/data

　　　　II、建立文件：/opt/zookeeper/zkdata/data/myid ，內容爲"106"  ，或者使用命令快速生成：

echo 106>/opt/zookeeper/zkdata/data/myid

 

 

4、三臺機器中，都爲防火牆中添加218一、288八、3888端口入站。

添加端口：
　　firewall-cmd --zone=public --add-port=2181/tcp --permanent
　　firewall-cmd --zone=public --add-port=2888/tcp --permanent
　　firewall-cmd --zone=public --add-port=3888/tcp --permanent
從新載入：
　　firewall-cmd --reload

 

5、啓動Zookeeper：三臺機器中依次運行

/opt/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start /opt/zookeeper/zookeeper-3.4.13/conf/zoo.cfg
