1.MySQL介绍
MySQL是一个流行的开源关系型数据库管理系统，广泛应用于Web应用程序开发中。MySQL最初由瑞典公司MySQL AB开发，现在由Oracle公司持有和维护。MySQL支持多种操作系统，包括Linux、Windows和Mac OS等。
以下是MySQL的一些特点和优势：
- 开源免费：MySQL是开源软件，可以免费使用，这使得它成为许多开发者和组织的首选数据库管理系统。
- 跨平台性：MySQL支持多种操作系统，包括各种Linux发行版、Windows和Mac OS等，使其能够在不同的环境中运行。
- 高性能：MySQL是一个高性能的数据库管理系统，能够处理大量数据和高并发请求。
- 可靠性：MySQL具有良好的稳定性和可靠性，能够保证数据的安全性和完整性。
- 易于使用：MySQL的语法简单易懂，容易学习和使用，适合各种规模的应用程序开发。
- 支持标准SQL：MySQL遵循SQL（Structured Query Language）标准，与其他数据库系统兼容，开发者可以轻松迁移和管理数据。
- 丰富的功能：MySQL提供了许多功能丰富的工具和插件，如存储过程、触发器、视图等，可以满足各种复杂的数据库需求。
总的来说，MySQL是一个强大、稳定且易于使用的关系型数据库管理系统，适用于各种规模的应用程序开发，特别是Web应用程序开发。
2.MySQL安装
2.1 主机初始化
2.1.1 设置网卡名和ip地址
Rocky 9和CentOS Stream 9：
# Rocky 9和CentOS Stream 9默认支持修改网卡名。
[root@rocky9 ~]# grep 'plugins' /etc/NetworkManager/NetworkManager.conf

2.3.2 用户和组
useradd -s /sbin/nologin -r mysql
2.3.3 准备程序文件
MySQL二进制包下载，去“https://www.mysql.com/”网站下载，选择“DOWNLOADS”。
在弹出的网页，选择“MySQL Community (GPL) Downloads”。
然后选择“MySQL Community Server”。
然后版本选择“8.0.36”，操作系统选择“Linux-Generic”，下面的系统版本有3个，分别是“glibc 2.8、glibc 2.12、glibc 2.17”，这个根据系统的glibc版本下载。

2.4.2 做准备用户和数据目录
useradd -r -s /sbin/nologin -d /data/mysql mysql
2.4.3 准备数据库目录
mkdir -p /data/mysql
chown mysql.mysql /data/mysql
2.4.4 源码编译安装
编译安装说明
利用cmake编译,而利用传统方法，cmake的重要特性之一是其独立于源码(out-of-source)的编译功能，即编译工作可以在另一个指定的目录中而非源码目录中进行，这可以保证源码目录不受任何一次编译的影响，因此在同一个源码树上可以进行多次不同的编译，如针对于不同平台编译
编译选项:https://dev.mysql.com/doc/refman/5.7/en/source-configuration-options.html
2.4.4.1 下载并解压缩源码包
MySQL源码包下载，去“https://www.mysql.com/”网站下载，选择“DOWNLOADS”。
在弹出的网页，选择“MySQL Community (GPL) Downloads”。
然后选择“MySQL Community Server”。
然后版本选择“8.0.36”，操作系统选择“Source Code”，系统版本选择“All Operating Systems (Generic) (Architecture Independent)”，然后选择下面的“mysql-boost-8.0.36.tar.gz”包后面的“Download”进行下载。
cd /usr/local/src/wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.36.tar.gztar xvf mysql-boost-8.0.36.tar.gz
