文章目录

• [4.mysql 5.x源码安装](#4.mysql 5.x源码安装)
• • 基础SQL语句
  • python导出表

环境准备：

使用CentOS-7-template模板克隆mysql01

#设置主机名
[root@localhost ~]# hostnamectl set-hostname mysql01
#关闭防火墙
[root@mysql01 ~]# systemctl disable firewalld.service --now

mysql5.7稳定版安装

#安装依赖包，ncurses（操作终端） ncurses-devel（编译软件时用）bison（解析语法） cmake（源码编译工具） gcc，gcc-c++（编译器）
[root@mysql01 ~]# yum -y install ncurses ncurses-devel bison cmake gcc gcc-c++

#配置程序用户（不允许终端登录）
[root@mysql01 ~]# useradd -s /sbin/nologin mysql

#解压mysql和boost包到指定目录，boost是支持mysql底层c++运行的仓库
[root@mysql01 ~]# tar zxvf mysql-5.7.17.tar.gz -C /opt/
[root@mysql01 ~]# tar zxvf boost_1_59_0.tar.gz -C /usr/local/
[root@mysql01 ~]# cd /usr/local/
[root@mysql01 ~]# mv boost_1_59_0 boost

#配置安装环境
[root@mysql01 ~]# cd /opt/mysql-5.7.17/
[root@mysql01 mysql-5.7.17]# cmake \

python导出表

先配置pip源：

Windows系统：

在用户目录下（如 C:\Users\你的用户名\）创建一个名为 pip 的文件夹。

以我举例

C:\Users\69466

在 pip 文件夹内创建一个名为 pip.ini 的文件。

用记事本打开 pip.ini，输入以下内容并保存：

[global]
index-url = https://mirrors.aliyun.com/pypi/simple/
trusted-host = mirrors.aliyun.com

pycharm下载软件包

pip install pandas
pip install sqlalchemy --only-binary :all: -i https://mirrors.aliyun.com/pypi/simple/
pip install pymysql
pip install openpyxl

下图演示了pip install pandas，另外3个一样

代码如下

import pandas as pd
from sqlalchemy import create_engine

#创建数据连接
engine = create_engine('mysql+pymysql://root:huawei@192.168.108.142:3306/school')

#执行获取数据
df = pd.read_sql('select * from info', engine)
print(df)

#导出到excel表格
df.to_excel('info.xlsx', index=False)
print('excel 导出成功！')

右击项目，新建python文件

根据项目位置找到，输出的excel
