hadoop-2.7.3的集群搭建:https://blog.youkuaiyun.com/qq_41028958/article/details/80817337
1.上传zk安装包到/usr/local/app
zookeeper-3.4.9.tar.gz
配置环境变量:
[hadoop@master app]$ vi ~/.bashrc
export ZOOKEEPER_HOME=/usr/local/soft/zookeeper-3.4.9
export PATH=.:$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin:$JAVA_HOME/bin:$PATH
[hadoop@master app]$ source ~/.bashrc
2.解压
[hadoop@master local]$ tar -zxvf ./app/zookeeper-3.4.9.tar.gz -C ./soft/
3.配置(先在一台节点上配置)
[hadoop@master conf]$ pwd
/usr/local/soft/zookeeper-3.4.9/conf
mv zoo_sample.cfg zoo.cfg
[hadoop@master 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=/usr/local/soft/zookeeper-3.4.9/data //此文件夹需要手工创建
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# 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
server.0=master:2888:3888
server.1=slave1:2888:3888
server.2=slave2:2888:3888
在data目录内创建一个myid文件,里面内容是server.N中的N
[hadoop@master data]$ vi myid
0
[hadoop@master data]$ cat myid
0
将配置好的zoo
keeper-3.4.9拷贝到其他节点[hadoop@master soft]$ scp -r ./zookeeper-3.4.9/ slave1:/usr/local/soft
[hadoop@master soft]$ scp -r ./zookeeper-3.4.9/ slave2:/usr/local/soft
注意:在其他节点上一定要修改myid的内容
在slave1应该讲myid的内容改为1
在slave2应该讲myid的内容改为2
启动集群
分别启动zookeeper-3.4.9
master:
slave1:
slave2:
至此zookeeper-3.4.9搭建集群完毕!!!
