hadoop,zookeeper,hbase集群配置

分类： LINUX

2017-08-11 15:55:31

记录一次hadoop的安装配置，
版本号：Hadoop 2.7.3，
三台机器：test,home-test,hbase-test（主机名随便起，不过要先在/etc/hosts配置好）
创建一个hadoop账户，来安装hadoop,也可以直接使用root安装，配置好三台机器ssh无密码登陆，如下：
useradd hadoop;passwd hadoop;ssh-keygen -t rsa(直接回车，回车）;cp -a ~/.ssh/id_rsa.pub authorized_keys;把authorized_keys传给其他两台机器，相同，在其他两台机器也这样做，确保从任何一台机器登陆其他两台都不需要密码！

安装hadoop之前，需要先把java环境配置好,直接解压jdk到/usr/local/lib,然后配置变量
~/.bashrc:

点击(此处)折叠或打开

  1. export JAVA_HOME=/usr/local/lib/jdk1.8.0_144
  2. export JAVA_BIN=$JAVA_HOME/bin
  3. export JAVA_LIB=$JAVA_HOME/lib
  4. export CLASSPATH=.:$JAVA_LIB/tools.jar:$JAVA_LIB/dt.jar
  5. export PATH=$JAVA_BIN:$PATH
现在安装hadoop，直接解压hadoop的/usr/local/目录，开始配置变量：

  1. # Hadoop Environment Variables
  2. export HADOOP_HOME=/usr/local/hadoop
  3. export HADOOP_INSTALL=$HADOOP_HOME
  4. export HADOOP_MAPRED_HOME=$HADOOP_HOME
  5. export HADOOP_COMMON_HOME=$HADOOP_HOME
  6. export HADOOP_HDFS_HOME=$HADOOP_HOME
  7. export YARN_HOME=$HADOOP_HOME
  8. export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
  9. export PATH=$HADOOP_HOME/sbin:$HADOOP_HOME/bin:$PATH
  10. export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"
  11. export LD_LIBRARY_PATH=$HADOOP_HOME/lib/native

slave文件加入两个datanode的主机名
以上配置好后，把整个hadoop目录拷贝到另外两台机器，现在准备配置zookeeper,
把zookeeper解压到/usr/local/zookeeper的配置文件zoo.cfg：

点击(此处)折叠或打开

  1. # The number of milliseconds of each tick
  2. tickTime=2000
  3. # The number of ticks that the initial
  4. # synchronization phase can take
  5. initLimit=10
  6. # The number of ticks that can pass between
  7. # sending a request and getting an acknowledgement
  8. syncLimit=5
  9. # the directory where the snapshot is stored.
  10. # do not use /tmp for storage, /tmp here is just
  11. # example sakes.
  12. dataDir=/opt/zookeeper/data
  13. dataLogDir=/opt/zookeeper/logs
  14. # the port at which the clients will connect
  15. clientPort=2181
  16. server.0=192.168.2.131:2888:3888
  17. server.1=192.168.2.138:2888:3888
  18. server.2=192.168.2.139:2888:3888
  19. # the maximum number of client connections.
  20. # increase this if you need to handle more clients
  21. maxClientCnxns=60
  22. #
  23. # Be sure to read the maintenance section of the
  24. # administrator guide before turning on autopurge.
  25. #
  26. # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
  27. #
  28. # The number of snapshots to retain in dataDir
  29. #autopurge.snapRetainCount=3
  30. # Purge task interval in hours
  31. # Set to "0" to disable auto purge feature
  32. #autopurge.purgeInterval=1
分别在/opt目录创建data和logs目录：mkdir -p /opt/{data,logs}
并在data目录里面创建myid文件，填入当前机器的number,如当前机器是test,按照你的配置文件：server.0=192.168.2.131:2888:3888,直接在myid填入0

把zookeeper整个目录，拷贝到其他两台机器，主要要修改对应的myid号

紧接着，可以来弄hbase了，解压hbase到任意目录，修改配置hbase-site.xml：

点击(此处)折叠或打开

  1. <configuration>
  2.        <!--HBase数据目录位置-->
  3.    <property>
  4.        <name>hbase.rootdir</name>

  6.    </property>
  7.        <!--启用分布式集群-->
  8.    <property>
  9.        <name>hbase.cluster.distributed</name>
  10.        <value>true</value>
  11.    </property>
  12.        <!--默认HMaster HTTP访问端口-->
  13.    <property>
  14.        <name>hbase.master.info.port</name>
  15.        <value>17010</value>
  16.     </property>
  17.        <!--默认HRegionServer HTTP访问端口-->
  18.     <property>
  19.        <name>hbase.regionserver.info.port</name>
  20.        <value>16030</value>
  21.     </property>
  22.        <!--不使用默认内置的，配置独立的ZK集群地址-->
  23.    <property>
  24.        <name>hbase.zookeeper.quorum</name>
  25.        <value>test,home-test</value>
  26.    </property>
  27. <property>
  28. <name>hbase.zookeeper.property.dataDir</name>
  29. <value>/opt/zookeeper/data</value>
  30. </property>
  31. </configuration>
配置hbase的环境:
~/.bashrc

点击(此处)折叠或打开

  1. #Hbase Environment
  2. HBASE_HOME=/opt/hbase-1.2.6
  3. export PATH=$HBASE_HOME/bin:$PATH
hbase自带zookeeper,不适用自带的需要关闭它：
hbase-env.sh:

点击(此处)折叠或打开

  1. # Tell HBase whether it should manage it's own instance of Zookeeper or not.
  2. export JAVA_HOME="/usr/local/lib/jdk1.8.0_144"
  3. export HBASE_CLASSPATH=$HADOOP_HOME/etc/hadoop
  4. export HBASE_MANAGES_ZK=false<---这个true的话，是使用hbase自带的zookeeper
拷贝整个hbase目录到另外两台机器，到这里基本该做的做完了，现在可以启动了，先启动zookeeper:
zkServer.sh start<---每一台都执行，然后zkServer.sh status看一下结果：

点击(此处)折叠或打开

  1. ZooKeeper JMX enabled by default
  2. Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
  3. Mode: follower

  5. ZooKeeper JMX enabled by default
  6. Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
  7. Mode: leader
启动zookeeper成功，现在来启动hadoop:start-dfs.sh && start-yarn.sh,命令jps看一下结果：

点击(此处)折叠或打开

  1. Master(Namenode)上的：
  2. 1232 QuorumPeerMain
  3. 1608 SecondaryNameNode
  4. 1770 ResourceManager
  5. 8012 Jps
  6. 1407 NameNode

  8. DataNode上的:
  9. 2275 QuorumPeerMain
  10. 2389 DataNode
  11. 4217 Jps
  12. 2506 NodeManager
可以看到正常启动，不错，现在开启hbase,命令start-hbase.sh，命令jps查看结果：

点击(此处)折叠或打开

  1. Master(NameNode)上的：
  2. 1232 QuorumPeerMain
  3. 3732 HMaster
  4. 1608 SecondaryNameNode
  5. 1770 ResourceManager
  6. 8012 Jps
  7. 1407 NameNode

  9. DataNode上的：
  10. 2275 QuorumPeerMain
  11. 2389 DataNode
  12. 3159 HRegionServer
  13. 4217 Jps
  14. 2506 NodeManager
可以看到NameNode和DataNode个多了一个进程，HMaster和HRegionServer,表明hbase已经其启动了，一般来说，在master上启动，会把其他的节点也一起启动，如果其他节点没有启动成功，登陆其他节点，使用命令:hbase-daemon.sh start regionserver

到此，基本上配置好了，值得注意的是，上面hadoop配置完成后，需要先格式化hdfs,Master上执行：hdfs namenode -format
按照上面的配置会在/usr/local/hadoop/tmp生成name和data目录，

现在打开hbase shell验证一下hbase,还有按照上面的配置也可以直接通过web访问hbase,地址：

点击(此处)折叠或打开

  1. [hadoop@test ~]$ hbase shell
  2. SLF4J: Class path contains multiple SLF4J bindings.
  3. SLF4J: Found binding in [jar:file:/opt/hbase-1.2.6/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
  4. SLF4J: Found binding in [jar:file:/usr/local/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class]
  5. SLF4J: See for an explanation.
  6. SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
  7. HBase Shell; enter 'help' for list of supported commands.
  8. Type "exit" to leave the HBase Shell
  9. Version 1.2.6, rUnknown, Mon May 29 02:25:32 CDT 2017

  11. hbase(main):001:0> status
  12. 1 active master, 0 backup masters, 2 servers, 0 dead, 1.0000 average load

  14. hbase(main):002:0>
可以看到，没问题了，按照上面的配置，hbase的数据是在hdfs的/hbase上，查看一下：

可以看到，有数据,没问题！

到此，也差不多了，可能有些小的细节没写清楚，以后慢慢补充吧，下一篇会是spark的集群！
