安装mysql

mysql装在了master节点上

1)卸载系统自带的mysql相关安装包，仅卸载 mysql 开头的包

rpm -qa|grep -i mysql

-i 作用是不区分大小写

可以看到有两个安装包

MySQL-server-5.6.19-1.linux_glibc2.5.x86_64.rpm

MySQL-client-5.6.19-1.linux_glibc2.5.x86_64.rpm

删除这两个服务(去掉后缀)

rpm -e MySQL-client-5.6.19-1.linux_glibc2.5.x86_64

rpm -e MySQL-server-5.6.19-1.linux_glibc2.5.x86_64

查看残留的目录：

whereis mysql

然后删除mysql目录：

rm –rf /usr/lib64/mysql

删除相关文件：

rm –rf /usr/my.cnf

rm -rf /root/.mysql_sercret

最关键的：

rm -rf /var/lib/mysql

2)安装mysql依赖

yum install vim libaio net-tools

3)安装mysql5.5.39的rpm包

rpm -ivh /opt/MySQL-server-5.5.39-2.el6.x86_64.rpm

rpm -ivh /opt/MySQL-client-5.5.39-2.el6.x86_64.rpm

4)拷贝配置文件

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

5)启动mysql服务

service mysql start

6)设置为开机自启动

chkconfig mysql on

7）设置root用户登录密码

/usr/bin/mysqladmin -u root password ‘root‘

8)登录mysql 以root用户身份登录

mysql -uroot –proot

安装hive

hive装在了master节点上

1)在mysql中创建hive用户,数据库等

insert into mysql.user(Host,User,Password) values("localhost","hive",password("hive"));

create database hive;

grant all on hive.* to hive@‘%‘ identified by ‘hive‘;

grant all on hive.* to hive@‘localhost‘ identified by ‘hive‘;

flush privileges;

2)退出mysql

exit

3)添加环境变量

4)修改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.ConnectionPassword</name>

<value>hive</value>

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

</property>

<property>

<name>hive.hwi.listen.port</name>

<value>9999</value>

<description>This is the port the Hive Web Interface will listen on</description>

</property>

<property>

<name>datanucleus.autoCreateSchema</name>

<value>true</value>

<description>creates necessary schema on a startup if one doesn‘t exist. set this to false, after creating it once</description>

</property>

<property>

<name>datanucleus.fixedDatastore</name>

<value>false</value>

<description/>

</property>

<property>

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

<value>hive</value>

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

</property>

<property>

<name>hive.exec.local.scratchdir</name>

<value>/opt/apache-hive-1.2.1-bin/iotmp</value>

<description>Local scratch space for Hive jobs</description>

</property>

<property>

<name>hive.downloaded.resources.dir</name>

<value>/opt/apache-hive-1.2.1-bin/iotmp</value>

<description>Temporary local directory for added resources in the remote file system.</description>

</property>

<property>

<name>hive.querylog.location</name>

<value>/opt/apache-hive-1.2.1-bin/iotmp</value>

<description>Location of Hive run time structured log file</description>

</property>

5)拷贝mysql-connector-java-5.1.6-bin.jar 到hive 的lib下面

mv /home/hdpsrc/Desktop/mysql-connector-java-5.1.6-bin.jar /home/hdpsrc/hive/lib/

6)把jline-2.12.jar拷贝到hadoop相应的目录下，替代jline-0.9.94.jar，否则启动会报错

cp /home/hdpsrc/hive/lib/jline-2.12.jar /home/hdpsrc/hadoop-2.6.3/share/hadoop/yarn/lib/

mv /home/hdpsrc/hadoop-2.6.3/share/hadoop/yarn/lib/jline-0.9.94.jar /home/hdpsrc/hadoop-2.6.3/share/hadoop/yarn/lib/jline-0.9.94.jar.bak

7)创建hive临时文件夹

mkdir /home/hdpsrc/hive/iotmp

8)启动测试hive

启动hadoop后，执行hive命令

hive

测试输入 show database;

hive> show databases;

OK
