缘
过了个周末，舒舒服服，把家里捣鼓了下，自己编了一个网格照片墙，把来做客的家具都安排好位置，今天，继续上班啦。
环境
开始之前，老生常谈，首先看看我服务器的信息：
[root@VM-16-11-centos ~]# uname -a
Linux VM-16-11-centos 3.10.0-1160.99.1.el7.x86_64 #1 SMP Wed Sep 13 14:19:20 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
下载
虽然每次写mysql教程都会写下载链接，这次依然附带上。提供两种方式下载，
** 下载地址：**直接下载mysql数据库tar格式，官网下载地址
** 下载页面：**在页面找自己想要的版本进行安装，官网下载页面
安装
- 离线服务器下载后放到服务器上，联网服务器直接使用命令下载：
wget https://dev.mysql.***/get/mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar
- 对压缩包进行解压
[root@VM-16-11-centos mysqls]# tar -xvf mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar

3. 安装解压出来的rpm安装包。如下：
[root@VM-16-11-centos mysqls]# rpm -ivh *.rpm --nodeps --force

4. 使用命令查看安装是否成功，如下：
[root@VM-16-11-centos mysqls]# systemctl status mysqld
● mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

5. 启动mysql服务，如下：

6. 查看数据库密码，和往常一样依然是随机密码，有日志可知本次密码为k*;2bsNU)&Oo，如下：

截图如下：
7.测试数据库链接，命令如下：
[root@VM-16-11-centos ~]# mysql -u root -p
Enter password:

截图如下：
- 基于以上，mysql安装完成！烨！✌
可以连接以后，记得修改密码，命令：
ALTER USER USER() IDENTIFIED BY 'Root@123';
截图如下：
如果有修改配置文件的需求，使用以下命令修改配置文件，修改后重启生效：
[root@VM-16-11-centos ~]# vim /etc/my.***f
截图如下：
问题集锦
- 修改密码时报错：
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
解决方案：
意思是密码强度不够，试试大小写数字加符号。
或者执行以下命令后重试：
#查看密码配置
show variables like 'validate_password%';
#设置密码强度
SET GLOBAL validate_password.policy=LOW;
SET GLOBAL validate_password.length=0;
SET GLOBAL validate_password.mixed_case_count=0;
SET GLOBAL validate_password.number_count=0;
SET GLOBAL validate_password.special_char_count=0;
FLUSH PRIVILEGES;
ALTER USER USER() IDENTIFIED BY 'iceter';
修改成功，注意：不要修改成关键字，比如：root，依然会报错。
- 安装时候报错：
error: unpacking of archive failed: cpio: Bad magic
解决方案：
查看mysql版本与Linux系统版本是否一致。重新下载版本一致的进行安装即可。
