mysql与hive2.1.1安装和配置

1.mysql安装

这个安装很简单，是在线安装，只需要按顺序执行一下几个命令就ok了。

（1）sudo apt-get install mysql-server

（2）sudo apt-get install mysql-client

（3）sudo apt-get install libmysqlclient-dev

（4）sudo apt-get installlibmysql-java

（5）将/usr/share/java/mysql-connector-java-5.1.28.jar拷贝到hive的lib目录下

cp
mysql-connector-java-5.1.28.jar /home/xqshi/Downloads/hadoop/apache-hive-2.1.1-bin/lib

安装过程会让你给数据库root用户输入密码，不要忽略。然后通过如下命令检查是否安装成功：

root@ubuntu:/usr/local# sudo netstat -tap | grep mysql
root@ubuntu:/usr/local# sudo /etc/init.d/mysql restart

登录验证：

root@ubuntu:/usr/local# mysql -hlocalhost -uroot -pxqshi

2.正确安装hadoop

3.下载hive安装文件apache-hive-2.1.1-bin.tar.gz，解压
4. 修改配置环境变量 vi ~/.bahrc

export JAVA_HOME=/home/xqshi/Downloads/hadoop/jdk1.8.0_91
export JRE_HOME=/home/xqshi/Downloads/hadoop/jdk1.8.0_91/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin:$PATH
export HADOOP_HOME=/home/xqshi/Downloads/hadoop/hadoop-2.8.0
export PATH=${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin:$PATH
export IDEA_JDK=/home/xqshi/Downloads/hadoop/jdk1.8.0_91
export HIVE_HOME=/home/xqshi/Downloads/hadoop/apache-hive-2.1.1-bin
export PATH=${HIVE_HOME}/bin:$PATH

5.修改Hive配置hive-config.sh

vi /bin/hive-config.sh
export JAVA_HOME=/home/xqshi/Downloads/hadoop/jdk1.8.0_91
export HIVE_HOME=/home/xqshi/Downloads/hadoop/apache-hive-2.1.1-bin
export HADOOP_HOME=/home/xqshi/Downloads/hadoop/hadoop-2.8.0

6.修改hive-env.sh

cp hive-env.sh.template hive-env.sh

7.修改hive-site.xml

cp hive-default.xml.template hive-site.xml
vi hive-site.xml
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive</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>数据库用户名</value>
<description>Username to use against metastore database</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>数据库密码</value>
<description>password to use against metastore database</description>
</property>

#如果不配置下面的部分会产生错误1.
<property>
<name>hive.exec.local.scratchdir</name>
<value>自定义目录</value>
<description>Local scratch space for Hive jobs</description>
</property>
<property>
<name>hive.downloaded.resources.dir</name>
<value>自定义目录</value>
<description>Temporary local directory for added resources in the remote file system.</description>
</property>
<property>
<name>hive.querylog.location</name>
<value>自定义目录</value>
<description>Location of Hive run time structured log file</description>
</property>
<property>
<name>hive.server2.logging.operation.log.location</name>
<value>自定义目录/operation_logs</value>
<description>Top level directory where operation logs are stored if logging functionality is enabled</description>
</property>

8.修改hive-log4j.properties

cp hive-log4j.properties.template hive-log4j.properties
vim hive-log4j.properties
hive.log.dir=自定义目录/log/

9.在HDFS上建立/tmp和/user/hive/warehouse目录，并赋予组用户写权限。

HADOOP_HOME/bin/hadoop fs -mkdir       /tmp
HADOOP_HOME/bin/hadoop fs -mkdir       /user/hive/warehouse
HADOOP_HOME/bin/hadoop fs -chmod g+w   /tmp
HADOOP_HOME/bin/hadoop fs -chmod g+w   /user/hive/warehouse

10.mysql配置

#创建数据库
mysql> create database hive;
#赋予访问权限

schematool -dbType mysql -initSchema

mysql> grant all privileges on hive.* to root@localhost identified by '密码' with grant option;mysql> flush privileges;#将JDBC复制到Hive库目录用于java程序与mysql的连接cp
mysql-connector-java-5.1.28.jar /home/xqshi/Downloads/hadoop/apache-hive-2.1.1-bin/lib

11.初始化hive，在hive2.0以后的版本，初始化命令都是：

schematool -dbType mysql -initSchema

12.始化成功后，就可以运行hive了，可以检测一下hive是否正常
