1.下載zookeeper：

wget http://apache.fayea.com/zookeeper/stable/zookeeper-3.4.6.tar.gz

2.解壓

tar zxvf zookeeper-3.4.6.tar.gz

3.配置

進入配置資料夾，將zoo_sample.cfd檔名稱改為zoo.cfg, 預設的配置內容如下

# 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=/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

配置說明：

tickTime：這個時間是作為 Zookeeper 伺服器之間或客戶端與伺服器之間維持心跳的時間間隔，也就是每個 tickTime 時間就會發送一個心跳。

dataDir：顧名思義就是 Zookeeper 儲存資料的目錄，預設情況下，Zookeeper 將寫資料的日誌檔案也儲存在這個目錄裡。

dataLogDir: log目錄, 同樣可以是任意目錄. 如果沒有設定該引數, 將使用和dataDir相同的設定。

clientPort：這個埠就是客戶端連線 Zookeeper 伺服器的埠，Zookeeper 會監聽這個埠，接受客戶端的訪問請求。

4、啟動Zookeeper

當這些配置項配置好後，你現在就可以啟動zookeeper了：

./zkServer.sh start #啟動
netstat -tunlp|grep 2181 #檢視zookeeper埠
./zkServer.sh stop #停止
