[置顶] linux环境下的hive mysql hadoop环境搭建

软件环境

Centos6.5
vmware workstation 11
JDK1.6或者以上版本
hadoop-1.2.1
hive-0.8.1
ssh

hadoop环境搭建

1. sshd服务安装和配置ssh免密码登陆
   一般来说Linux下默认安装了ssh服务,运行service sshd start启动ssh服务.如果没有安装的，可以使用yum install ssh来安装sshd服务.
   在ssh服务启动之后,运行ssh-keygen -t dsa -P ” -f ~/.ssh/id_dsa
   
   运行之后，在~/.ssh/目录下生成一个秘钥文件id_dsa.pub
   讲这个秘钥中内容拷贝到authorized_keys中.
   cat id_dsa.pub > authorized_keys
   全部运行完之后在终端运行
   ssh localhost看看有没有配置成功
   

2. 关闭Linux上iptables
   

3. jdk安装
   tar -zxvf jdk-8u31-linux-i586.gz
   mv mv jdk1.8.0_31 /usr/local/lib/jdk
   /etc/profile中追加以下几行
   export JAVA_HOME=/usr/local/lib/jdk
   export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
   export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
   运行java -v,显示如下画面，说明Java安装成功
   
   *PS:linux默认安装了jdk,建议事先删除Linux上的jdk。
   rpm -qa | grep jdk | xargs rpm -e

4. hadoop安装
   解压。
   cp hadoop-1.2.1.tag.gz /home/拷贝文件/
   tar -zxvf hadoop-1.2.1.tag.gz/解压/
   ln -s hadoop-1.2.1 hadoop/监理符号链接/
   在/etc/profile中追加下面几行
   export HADOOP_HOME=/home/hadoop
   export PATH=$PATH:$HADOOP_HOME/bin:\$HADOOP_HOME/sbin

   export CLASSPATH=$CLASSPATH:$HADOOP_HOME:$HADOOP_HOME/hadoop-core-1.2.1.jar
   cd /home/hadoop/conf

将 core-site.xml中内容修改成

<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/data/hadooptmp</value>
</property>
<property>
<name>fs.default.name</name>
<value>hdfs://192.168.24.129:9000</value>
</property>
</configuration>

/home/data/hadooptmp目录需要提前创建
192.168.24.129时namenode的地址

修改hadoop-env.sh

echo “export JAVA_HOME=”$JAVA_HOME >> hadoop-env.sh

修改hdfs-site.xml

<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>

修改master和slave

master中填入namenode的ip
slave中填入datanode的ip

启动hadoop

cd /home/hadoop/bin
./start-all.sh

或者浏览器出入http://192.168.24.129:50070/

Mysql搭建

•yum install mysql-server
•建立数据库hive
•create database hive
•创建hive用户,并授权
•grant all on hive.* to hive@’%’ identified by ‘hive’;
•flush privileges;

Hive搭建

tar -zxvf hive-0.8.1.tar.gz
ln -s tar -zxvf hive-0.8.1 hive
/etc/profile中追加以下几行

 export HIVE_HOME=/home/hive
 export PATH=$PATH:.:$HIVE_HOME/bin
 export CLASSPATH=$CLASSPATH:$HIVE_HOME/lib

cp mysql-connector-java-5.1.18-bin.jar ./hive/lib
cd hive/conf
cp hive-default.xml.template hive-site.xml
修改hive中-site.xml
