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,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!

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
