一、环境描述
Mysql版本:mysql-installer-community-5.5.27.1 32位
Mysql for Windows 7 32位:我把mysql数据库安装在了自己win7的笔记本上,这样的好处就是减少了虚拟机master slave的开销和使用空间还可以多利用一台机器的资源,如果你的虚拟机资源很紧张的话也可以这样部署。
Linux ISO:CentOS-6.0-i386-bin-DVD.iso 32位
JDK version:"1.6.0_25-ea"
Hadoop software version:hadoop-0.20.205.0.tar.gz
Hbase version:hbase-0.90.5
Hive version:hive-0.8.1.tar.gz
二、Mysql数据库注意事项
1.安装mysql数据库步骤略过,虚拟机网络设置成host-only模式,两边系统都关闭防火墙,,windows系统的360软件最好也关闭,有可能会影响通信。
数据库用户/密码:root/root 和hive/hive
数据库端口:3306
Mysqll服务名:MySQL55
以将MySQL服务器安装成服务。安装成服务,系统启动时可以自动启动MySQL服务器
目前设置为不随操作系统启动而自动启动
启动/关闭mysql数据库服务命令,必须启动服务才能操作数据库
net start mysql net stop mysql
2.查看Mysql版本(注意V大写)
3.登陆Mysql,从windows上登录
4.在mysql上建立hive用户并授予足够的权限
本人使用的是windows上mysql自带的MySQL workbench客户端软件创建的用户
Add Account:添加一个用户
Name:hive 密码 hive
Limit Connectivity to Hosts Matching:% 百分号是通配符意思,就是说不在限制登录的主机,你从任何一台客户机都可以登录,如果写上ip地址说明此用户只能从这个ip地址的机器上登录mysql数据库
全部勾选授予all权限
命令方式:Create user hive identified by hive;
