zookeeper入門學習(二)，zookeeper入門學習

zookeeper安裝

單機模式

首先，下載zookeeper-3.4.8.tar.gz

建立/usr/zookeeper，解壓到zookeeper目錄

[root@localhost zookeeper]# tar -zxvf zookeeper-3.4.8.tar.gz 

配置環境變數：

為了今後操作方便，我們需要對Zookeeper的環境變數進行配置，方法如下在/etc/profile檔案中加入如下內容：

[root@localhost liutie]# vi /etc/profile

#set java environment
JAVA_HOME=/usr/java/jdk1.8.0_131
JRE_HOME=/usr/java/jdk1.8.0_131/jre
ZOOKEEPER_HOME=/usr/zookpeer/zookpeer-3.4.8
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:ZOOKEEPER_HOME/bin

使環境變數生效

[root@localhost liutie]# source /etc/profile

進入zookeeper檔案夾的bin目錄修改zoo_simple.cfg為zoo.cfg

[root@localhost conf]# mv zoo_sample.cfg zoo.cfg

修改zoo.cfg

[root@localhost conf]# vi zoo.cfg 

# 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  #  # 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 

儲存後進入bin目錄啟動服務端

[root@localhost bin]# ./zkServer.sh start
