ZooKeeper配置

master配置

cd /usr/local/src/zookeeper
mkdir data && mkdir logs
echo 1 > /usr/local/src/zookeeper/data/myid
cp /usr/local/src/zookeeper/conf/zoo_sample.cfg /usr/local/src/zookeeper/conf/zoo.cfg
vi /usr/local/src/zookeeper/conf/zoo.cfg
#修改 dataDir引數內容如下：
dataDir=/usr/local/src/zookeeper/dat
#在 zoo.cfg檔案末尾追加以下引數配置，表示三個 ZooKeeper節點的訪問埠號
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:3888

[root@master ~] # scp -r /usr/local/src/zookeeper slave1:/usr/local/src/
[root@master ~] # scp -r /usr/local/src/zookeeper slave2:/usr/local/src/
 

slave配置

chown -R hadoop:hadoop /usr/local/src/zookeeper
echo 2 > /usr/local/src/zookeeper/data/myid
echo 3 > /usr/local/src/zookeeper/data/myid

環境變數

#三個節點都要改
vi /etc/profile
# 在檔案末尾追加

# set zookeeper environment 
export ZOOKEEPER_HOME=/usr/local/src/zookeeper   # ZooKeeper安裝目錄
export PATH=$PATH:$ZOOKEEPER_HOME/bin	# ZooKeeper可執行程式目錄
