1、創建 /usr/local/services/zookeeper 文件夾：
mkdir -p /usr/local/services/zookeeper
2、進入到 /usr/local/services/zookeeper 目錄中：
cd /usr/local/services/zookeeper
3、下載 zookeeper-3.4.9.tar.gz：
wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
4、解壓縮 zookeeper-3.4.9.tar.gz：
tar -zxvf zookeeper-3.4.9.tar.gz
5、進入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目錄中：
cd zookeeper-3.4.9/conf/
6、復制 zoo_sample.cfg 文件的並命名為為 zoo.cfg：
cp zoo_sample.cfg zoo.cfg
7、用 vim 打開 zoo.cfg 文件並修改其內容為如下：
# The number of milliseconds of each tick # zookeeper 定義的基准時間間隔，單位：毫秒 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 # 數據文件夾 dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data # 日志文件夾 dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs # the port at which the clients will connect # 客戶端訪問 zookeeper 的端口號 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
8、保存並關閉 zoo.cfg 文件:
9、進入到 /usr/local/services/zookeeper/zookeeper-3.4.9/bin 目錄中：
cd ../bin/
10、用 vim 打開 /etc/ 目錄下的配置文件 profile：
vim /etc/profile
並在其尾部追加如下內容：
#idea - zookeeper-3.4.9 config start - 2017-12-09 export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/ export PATH=$ZOOKEEPER_HOME/bin:$PATH export PATH #idea - zookeeper-3.4.9 config end - 2017-12-09
11、使 /etc/ 目錄下的 profile 文件即可生效：
source /etc/profile
12、啟動 zookeeper 服務：
zkServer.sh start
如打印如下信息則表明啟動成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
13、查詢 zookeeper 狀態：
zkServer.sh status
14、關閉 zookeeper 服務：
zkServer.sh stop
如打印如下信息則表明成功關閉：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
15、重啟 zookeeper 服務：
zkServer.sh restart
如打印如下信息則表明重啟成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
實際操作如下：
集群配置：
