ubuntu16配置ZooKeeper集羣（這裏用的是Zookeeper3.4.10）

1.安裝jdk:https://my.oschina.net/u/3316387/blog/1615301\

2.下載ZooKeeper：https://archive.apache.org/dist/zookeeper/，而後早/opt下建立一個目錄zookeeper，將下載好的文件解壓到這個目錄。

3.在zookeeper目錄下建立data,dataLog兩個目錄

4.在data下建立文件myid,並寫入1，其餘的機器分別寫上2，3......能夠隨便定義。

5.進入/opt/zookeeper/zookeeper-3.4.10/conf/,建立文件zoo.cfg,寫入如下代碼：

 

# 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=/tmp/zookeeper
# 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

dataDir=/opt/zookeeper/data  
dataLogDir=/opt/zookeeper/dataLog  
server.1=192.168.1.201:2888:3888

server.2=192.168.1.202:2888:3888

server.3=192.168.1.203:2888:3888

說明：dataDir和dataLogDir須要本身建立，目錄能夠本身制定，對應便可。server.1中的這個1須要和192.168.1.201這個機器上的dataDir目錄中的myid文件中的數值對應。server.2中的這個2須要和192.168.1.202這個機器上的dataDir目錄中的myid文件中的數值對應。固然，數值你能夠隨便用，只要對應便可。2888和3888的端口號也能夠隨便用，由於在不一樣機器上，用成同樣也無所謂。

6.進入/opt/zookeeper/zookeeper-3.4.10/bin/，編輯zkServer.sh 在程序的開頭添加上:

export JAVA_HOME=/usr/lib/jvm/jdk1.8  
export PATH=$JAVA_HOME/bin:$PATH

不添加會出現如下錯誤：

JMX enabled by default  

Using config: /usr/local/zookeeper-3.4.6/bin/../conf/zoo.cfg 

Error contacting service. It is probably not running. 

 

7.最後啓動zookeeper

sudo /opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh start

 

查看狀態

sudo /opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh status
