打算通过实践,系统学习一下数据分析。

初步计划要完成的三个任务。

一、用VMware装64位CentOS,数据库服务端用CentOS自带的就好。

二、数据采集与预处理用Dev-C++编程解决。

三、用本地Win7 64上的MATLAB R2012b连接数据库进行挖掘分析。

本文就是完成第一个任务的过程。

1.先上centos 官网下载centos7的DVD iso种子,然后把种子上传到百度云离线下载,再拖回本地。4M/s,很快搞定。

2.往VMware里装的时候遇到了问题。安装自检过程中报错“kernel panic - not syncing: Fatal exception”。问度娘,原来是CentOS7傲娇了,嫌弃VMware7版本太低。VMware升级到10.0解决。

3.省心,全默认选项安装。装完傻眼,无网yum不能用,无gui不会设置。不怕,有度娘。度娘提供了以下解决方案:

a.直接”yum groupinstall 'X Window System' -y“——无网导致失败。

b.挂载本地光盘后vi修改repo文件——yum报错失败。

c.用命令行"vi /etc/sysconfig/network-scripts/ifcfg-eth0"修改网卡配置文件,开DHCP动态获取ip——完全无效,还是无网。

4.不是度娘不给力,而是我太菜委屈,重装一次centos吧。安装过程中仔细看选项,配置好network,系统类型选择GNOME DESKTOP。

5.这回可算有网了。诶?centos7没有mysql了,新宠是mariadb?装!

a.换root登录

b.开Terminal,运行命令 ”yum -y install mariadb*"

c.启动数据库,Terminal运行命令"service mariadb start"

d.修改root密码,"mysqladmin -u root password '在这里设密码'"

e.登录数据库,"mysql -u root -p",输入上一步设定的密码

f.提示符下输个"show databases;"命令试试

MariaDB [(none)]> show databases;

结果出来了

+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
+--------------------+
4 rows in set (0.00 sec)

g.设置mariadb服务开机自启动

root用户#提示符下输入"systemctl enable mariadb.service"

任务一,mission accomplished!
