Ubuntu_安裝Zookeeper

下載zookeeper，http://archive.apache.org/dist/zookeeper/

解壓到: /opt/zookeeper-3.4.6下載

把conf下的zoo_sample.cfg copy一份後重新命名為: zoo.cfg.檔案中內容如下:
syncLimit=5
initLimit=10
tickTime=2000
clientPort=2181
dataDir=/opt/zookeeper-3.4.6/data
dataLogDir=/opt/zookeeper-3.4.6/logs

新建zookeeper-3.4.6下的data,log目錄,然後
chmod u+x /opt/zookeeper-3.4.6/bin/*

新建shell指令碼startZookeeper.sh在/opt/shell資料夾下，

內容：
#!/bin/sh
#to start zookeeper
#set environment
export ZOOKEEPER_INSTALL=/opt/zookeeper-3.4.6
export PATH=$PATH:$ZOOKEEPER_INSTALL/bin
PID_FILE=$ZOOKEEPER_INSTALL/data/zookeeper_server.pid
FLAG=$1

if [ “$FLAG” = “os_start” ] && [ -f “$PID_FILE” ]
then

       rm $PID_FILE

fi

chmod u+x /opt/shell/startZookeeper.sh

#start zookeeper
$ZOOKEEPER_INSTALL/bin/zkServer.sh start

設定zookeeper開機啟動
vim /etc/rc.local
在最後一行新增如下兩句話
#start zookeeper
/opt/shell/startZookeeper.sh
