一、安裝好java
二、配置 zookeeper：
1、創建 /usr/local/services/zookeeper 文件夾： mkdir -p /usr/local/services/zookeeper2、進入到 /usr/local/services/zookeeper 目錄中： cd /usr/local/services/zookeeper3、下載 zookeeper-3.4.9.tar.gz： wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz4、解壓縮 zookeeper-3.4.9.tar.gz： tar -zxvf zookeeper-3.4.9.tar.gz5、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 文件的并命名為為 zoo.cfg： cp zoo_sample.cfg zoo.cfg7、用 vim 打開 zoo.cfg 文件并修改其內容為如下： # The number of milliseconds of each tick # zookeeper 定義的基準時間間隔，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=18、保存并關閉 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 并在其尾部追加如下內容： # idea - zookeeper-3.4.9 config start - 2016-09-08 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 start - 2016-09-0811、使 /etc/ 目錄下的 profile 文件即可生效： source /etc/profile12、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 ... STARTED13、查詢 zookeeper 狀態： zkServer.sh status14、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 ... STOPPED15、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
如果出現 這類錯誤：
[root@localhost ~]# /usr/zookeeper/bin/zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /usr/zookeeper/bin/../conf/zoo.cfg
Stopping zookeeper ... /usr/zookeeper/bin/zkServer.sh: 第 182 行:kill: (2453) - 沒有那個進程
解決：安裝配置好java之后，需要賦予權限：
chmod +x /usr/java/jdk1.8/bin/java
