mkdir /tmp/zookeeper

tar -zxvf zookeeper-3.3.6.tar.gz

cp /hadoop/zookeeper-3.3.6/conf/zoo_sample.cfg /hadoop/zookeeper-3.3.6/conf/zoo.cfg

複製到其他主機

scp -r /hadoop/zookeeper-3.3.6 [email protected]:/hadoop/

scp -r /hadoop/zookeeper-3.3.6 [email protected]:/hadoop/

設定myid,用於標誌當前主機,myid值即上面配置檔案中 server.X=

echo "1" > /tmp/zookeeper/myid       -master

echo "2" > /tmp/zookeeper/myid       -node1

echo "3" > /tmp/zookeeper/myid       -node2

啟動,三臺都要.

cd /hadoop/zookeeper-3.3.6/bin

./zkServer.sh start

輸出:

JMX enabled by default
Using config: /hadoop/zookeeper-3.3.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

./zkServer.sh status

我的三臺分別是:

master:

JMX enabled by default
Using config: /hadoop/zookeeper-3.3.6/bin/../conf/zoo.cfg
Mode: follower

JMX enabled by default
Using config: /hadoop/zookeeper-3.3.6/bin/../conf/zoo.cfg
Mode: leader

JMX enabled by default
Using config: /hadoop/zookeeper-3.3.6/bin/../conf/zoo.cfg
Mode: follower

測試各Server是否已經啟動:

echo ruok|nc master 2181

echo ruok|nc node1 2181

echo ruok|nc node2 2181

收到 imok 資訊則表示成功了.

./zkServer.sh stop 停止
