    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

    1. 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.com/get/mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar
    1. 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 
mysql-community-client-8.0.36-1.el7.x86_64.rpm

    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)
   Active: inactive (dead)

[root@VM-16-11-centos mysqls]#

    截图如下：

    5. 启动mysql服务，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)

    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：

    7.测试数据库链接，命令如下：

    [root@VM-16-11-centos ~]# mysql -u root -p 
Enter password:

    1. 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.cnf

    问题集锦

    1. 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。

    1. 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。

    蜚语：自己捣鼓自己的房子，就是有一种莫名的成就感，哈哈哈，想朔朔的第n+1天，想媳妇的每一天~~~
