安装和配置hive

1、上传hive、mysql、mysql driver到服务器/mnt目录下：

[root@chavin mnt]# ll mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz apache-hive-0.13.1-bin.tar.gz mysql-connector-java-5.1.22-bin.jar

-rw-r--r--. 1 root root  54246778 Mar 13 10:46 apache-hive-0.13.1-bin.tar.gz

-rw-r--r--. 1 root root 312043744 Mar 13 10:46 mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz

-rw-r--r--. 1 root root    832960 Mar 13 10:46 mysql-connector-java-5.1.22-bin.jar

2、安装mysql数据库（mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz）

tar -zxvf mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz -C /opt/

mv mysql-5.6.24-linux-glibc2.5-x86_64/ mysql5624

yum -y install libaio

groupadd mysql

useradd -g mysql mysql

echo "dbking588" | passwd --stdin mysql

mv /etc/my.cnf /etc/my.cnf.bak

cp support-files/my-default.cnf /etc/my.cnf

/etc/my.cnf添加如下内容：

----------------------------------------------------------------------------------------------------

basedir = /opt/mysql5624

datadir = /opt/mysql5624/data

port = 3306

skip-grant-tables

log-error=/opt/mysql5624/data/mysql.log

pid-file=/opt/mysql5624/data/mysql.pid

scripts/mysql_install_db --user=mysql

chown -R mysql:mysql /opt/mysql5624/

cp support-files/mysql.server /etc/rc.d/init.d/mysql

chkconfig --add mysql

Service mysql start

3、安装hive

解压hive二进制包，并移动到相应安装目录下，我这里是/opt：

#tar -zxvf apache-hive-0.13.1-bin.tar.gz

#mv apache-hive-0.13.1-bin /opt/hive-0.13.1

拷贝/mnt下mysql驱动包到hive安装目录lib下：

#cp mysql-connector-java-5.1.22-bin.jar /opt/hive-0.13.1/lib/

进入hive conf/目录下，配置hive-env.sh及hive-site.xml文件：

#vim hive-env.sh

--修改以下两项：

HADOOP_HOME=/opt/hadoop

export HIVE_CONF_DIR=/opt/hive-0.13.1/conf

---------------------------------------------------------------------------

#vim hive-site.xml

编辑内容如下：

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>

<property>

<name>javax.jdo.option.ConnectionURL</name>

                <value>jdbc:mysql://chavin.king:3306/metastore?createDatabaseIfNotExist=true</value>

                <description>JDBC connect string for a JDBC metastore</description>

        </property>

<property>

<name>javax.jdo.option.ConnectionDriverName</name>

                <value>com.mysql.jdbc.Driver</value>

                <description>Driver class name for a JDBC metastore</description>

        </property>

<property>

<name>javax.jdo.option.ConnectionUserName</name>

                <value>root</value>

                <description>username to use against metastore database</description>

        </property>

<property>

<name>javax.jdo.option.ConnectionPassword</name>

<value>mysql</value>

<description>password to use against metastore database</description>

</property>

</configuration>

--hive安装完成。

现在可以通过bin/hive命令登录hive shell进行相应操作了。

--配置hive命令行显示库及表信息：在配置文件（hive-site.xml）中加入以下信息，重启客户端即可。

<property>

  <name>hive.cli.print.header</name>

  <value>true</value>

  <description>Whether to print the names of the columns in query output.</description>

</property>

<property>

  <name>hive.cli.print.current.db</name>

  <value>true</value>

  <description>Whether to include the current database in the Hive prompt.</description>

</property>

--再次登录，hive shell头显示如下：hive (chavin)>

--hive log日志配置：

[hadoop@db01 conf]$ cd /opt/hive-0.13.1/conf/

[hadoop@db01 conf]$ cp hive-log4j.properties.template hive-log4j.properties

[hadoop@db01 conf]$ vim hive-log4j.properties

修改内容相应log配置内容。

--启动时设置日志：

[hadoop@db01 hive-0.13.1]$ bin/hive --hiveconf hive.root.logger=info,console
