hadoop1.0.0,hbase0.92.0三节点安装

 

版本：hadoop-1.0.0,hbase-0.92.0

在195,196,197上安装hadoop集群
结果：195-》namenode
      196-》jobtracker,datanode
	  197-> SecondaryNameNode,datanode
1, 建hadoop用户
groupadd hadoop
useradd hadoop -g hadoop

passwd hadoop

mkdir -p /opt/hadoop
mkdir -p /opt/data/hadoop1
chown hadoop:hadoop /opt/hadoop
chown hadoop:hadoop /opt/data/hadoop1

2，修改hosts
vi /etc/hosts
10.10.249.195   master
10.10.249.196   slaver1
10.10.249.197   slaver2

3，生成密钥对
su - hadoop

ssh-keygen -t rsa

cd /home/hadoop/.ssh

cat id_rsa.pub > authorized_keys
cd /home/hadoop/.ssh
chmod 700 ../.ssh
chmod 600 *
chmod 644 authorized_keys

4，配置无密码 ssh登录
master:
cd /home/hadoop/.ssh
scp -r id_rsa.pub [email protected]:~/.ssh/pubkey_master
scp -r id_rsa.pub [email protected]:~/.ssh/pubkey_master
slaver1:
cd /home/hadoop/.ssh
cat pubkey_master  >> authorized_keys 

scp -r id_rsa.pub hadoop@master:~/.ssh/pubkey_slaver1
scp -r id_rsa.pub hadoop@slaver2:~/.ssh/pubkey_slaver1
slaver2:
cd /home/hadoop/.ssh
cat pubkey_master  >> authorized_keys 
cat pubkey_slaver1  >> authorized_keys 
scp -r id_rsa.pub hadoop@master:~/.ssh/pubkey_slaver2

master:
cat pubkey_slaver1 >> authorized_keys 
cat pubkey_slaver2 >> authorized_keys 

# su root 修改 /etc/ssh/sshd_config  PasswordAuthentication no

5:hadoop安装

conf/core-site.xml
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
  <name>fs.default.name</name>
  <value>hdfs://master:54310</value>
</property>
<property>
  <name>hadoop.tmp.dir</name>
  <value>/home/hadoop/hadoop_home/var</value>
</property>
</configuration>

conf/mapred-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>

  <value>slaver1:54311</value>
</property>
<property>
  <name>mapred.local.dir</name>
  <value>/home/hadoop/hadoop_home/var</value>
</property>
</configuration>

conf/hdfs-site.xml

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
  <name>dfs.replication</name>
  <value>3</value>
</property>
</configuration>


echo slaver2 > masters
echo master > slaves
echo slaver1 >> slaves
echo slaver2 >> slaves

196,197同此配置

master:

cd /opt/hadoop/hadoop-1.0.0/bin
./hadoop namenode -format

start-all.sh

./bin/hadoop dfs -copyFromLocal conf/ /user/hadoop/bookdata
./bin/hadoop jar hadoop-examples-1.0.0.jar wordcount /user/hadoop/bookdata /user/hadoop/book_data_out

job.tracker 50030
task.tracker 50060
dfs.http 50070
datanode.http 50075
secondary.http 50090

hadoop fs -mkdir /user/test
hadoop fs -chown test:test /user/test
hadoop dfsadmin -setSpaceQuota 1t /user/test


hbase安装步骤

master:195
RegionServer:196,197


1，修改三台hadoop的配置hdfs-site.xml， 
 
<property>
    <name>dfs.support.append</name>
    <value>true</value>
</property>
<property>
        <name>dfs.datanode.max.xcievers</name>
        <value>4096</value>
</property>

restart hdfs

#替换 hbase lib下的hadoop.jar为hdfs集群用的hadoop.jar


2，修改hbase-site.xml

<configuration> 
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://master:54310/hbase</value>
    <description>The directory shared by RegionServers.
    </description>
  </property>
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
    <description>The mode the cluster will be in. Possible values are
      false: standalone and pseudo-distributed setups with managed Zookeeper
      true: fully-distributed with unmanaged Zookeeper Quorum (see hbase-env.sh)
    </description>
  </property>
  <property>
    <name>dfs.support.append</name>
    <value>true</value>
</property>
 
</configuration>

3，修改regionservers
echo master > regionservers
echo slaver1 >> regionservers
echo slaver2 >> regionservers

4，修改hbase-env.sh :
 export HBASE_MANAGES_ZK=false #使用了单独安装的zookeeper， 
 
 export JAVA_HOME=/export/servers/jdk1.6.0_25
5，将zookeeper集群的zoo.cfg 复制到 hbase的conf目录下。


6，复制配置好hbase到slaver1,slaver2 /opt/hadoop目录下

7，增加可以打开的文件句柄数，三台机器都执行。
su root
echo -ne "
* soft nofile 65536
* hard nofile 65536
" >>/etc/security/limits.conf


安装完成，启动
cd  /opt/hadoop/hbase-0.92.0/bin

./start-hbase.sh  

master的web 端口，默认为60010，RegionServer web 端口 60030
