一、新建目錄
# 軟件安裝包存放目錄
mkdir -p /tools/soft
# zookeeper日誌和數據存放目錄
mkdir -p /data/zk
mkdir -p /data/logs
二、上傳文件並且改文件名
1.下載地址如下：
https://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/
# 上次文件
rz -be
# 解壓文件到tools目錄
tar -zxvf /tools/soft/zookeeper-3.4.6.tar.gz -C /tools/
# 重命名文件
mv /tools/zookeeper-3.4.6/ /tools/zookeeper
三、配置 /etc/profile
vi /etc/profile
最加如下：
# ZOOKEEPER_HOME
ZOOKEEPER_HOME=/tools/zookeeper
PATH=$PATH:$ZOOKEEPER_HOME/bin
export PATH ZOOKEEPER_HOME
四、修改 $ZOOKEEPER_HOME/conf/zoo.cfg 文件
# 將zoo_sample.cfg改名爲zoo.cfg
mv $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg
# 編輯zoo.cfg 如下
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zk
dataLogDir=/data/logs
clientPort=2181
五、啓動並檢驗是否成功
# 此爲啓動命令，在任意目錄下輸入
zkServer.sh start
# 此爲檢驗zk狀態命令，在任意目錄下輸入
zkServer.sh status
六、鏈接zookeeper
[root@miguvideo-10 /]# sh zkCli.sh -server 127.0.0.1:2181
