系統環境

• Ubuntu 16.04 LTS
• zookeeper-3.5.2-alpha.tar.gz

安裝步驟

1.下載ZooKeeper tar包並解壓

tar -zxvf zookeeper-3.5.2-alpha.tar.gz

2.進入解壓後文件夾下的conf目錄(/opt/apps/zookeeper/zookeeper-3.5.2-alpha/conf),複製一份zoo_sample.cfg重新命名為zoo.cfg

3.編輯zoo.cfg，修改以下配置

# 建立資料儲存目錄和日誌檔案目錄（目錄需要自己建立）
dataDir=/opt/apps/zookeeper/zookeeper
 
-3.5.2-alpha/data
dataLogDir=/opt/apps/zookeeper/zookeeper-3.5.2-alpha/logs

#設定server地址(hostname為本伺服器地址；第一個埠用於集合體中follower以偵聽leader；第二個埠用於leader選舉)
server.1=172.19.76.133:2888:3888

完整配置檔案如下

# 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=/opt/apps/zookeeper/zookeeper-3.5.2-alpha/data
dataLogDir=/opt/apps/zookeeper/zookeeper-3.5
 
.2-alpha/logs
# the port at which the clients will connect
clientPort=2181
server.1=172.19.76.133:2888:3888
# 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

4.在上一步建立的data目錄下建立mydata檔案，填入伺服器配置後面的數字，這裡為1，給伺服器進行編號

5.啟動ZooKeeper服務端

./zkServer.sh start

root@iZuf69wuhmgaijvje9a369Z:/opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

注意：請勿使用sh zkServer.sh start來啟動zkServer，會出現無法找到JAVA_HOME環境變數錯誤

6.檢視zkServer狀態

./zkServer.sh status

root@VM-0-15-ubuntu:/opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone
