一、本地下载安装
方法一
①在虚拟机火狐浏览器中搜索MySQL官网（选择第一个下载）
②下载完毕使用xshell远程连接解压及安装
[root@localhost ~]# cd /Downloads/
[root@localhost Downloads]# mkdir /mysql/
[root@localhost Downloads]# mv mysql-8.0.35-1.el9.x86_64.rpm-bundle.tar /mysql/
[root@localhost Downloads]# cd /mysql/
[root@localhost mysql]# tar xvf mv mysql-8.0.35-1.el9.x86_64.rpm-bundle.tar
[root@localhost mysql]# dnf localinstall mysql-community-server-8.0.35-1.el9.x86_64.rpm mysql-community-client-8.0.35-1.el9.x86_64.rpm mysql-community-common-8.0.35-1.el9.x86_64.rpm mysql-community-icu-data-files-8.0.35-1.el9.x86_64.rpm mysql-community-client-plugins-8.0.35-1.el9.x86_64.rpm mysql-community-libs-8.0.35-1.el9.x86_64.rpm
#重启服务
[root@localhost mysql]# systemctl start mysqld
#查看密码
[root@localhost mysql]# grep password /var/log/mysqld.log

#登录数据库
[root@localhost mysql]# mysql -uroot -p
Enter password: #此处密码是生成的随机密码

Bye方法二
[root@localhost ~]# wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.35-
1.el9.x86_64.rpm-bundle.tar
[root@localhost ~]# mkdir /mysql/
[root@localhost mysql]# tar xvf mysql-8.0.35-1.el9.x86_64.rpm-bundle.tar

二、本地仓库下载安装（本地安装的MySQL默认是没有密码的）
①配置本地仓库
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# vim /etc/yum.repos.d/wangluo.repo
[wangluo-app]
name=wanluo-app
baseurl=https://mirrors.aliyun.com/centos-stream/9-stream/AppStream/x86_64/os/
gpgcheck=0
[wangluo-base]
name=wangluo-base
baseurl=https://mirrors.aliyun.com/centos-stream/9-stream/BaseOS/x86_64/os/
gpgcheck=0
②下载
[root@localhost yum.repos.d]# mount /dev/sr0 /mnt #失败可能是没有挂载的原因
#下载（但它的版本不是最新的）
[root@localhost yum.repos.d]# dnf install mysql-server③测试
[root@localhost yum.repos.d]# systemctl start mysqld
[root@localhost yum.repos.d]# mysql -uroot -p #不需要密码直接回车
Enter password:

mysql> exit
Bye三、网络仓库下载安装
①找仓库文件（双击进去选择第一个下载）
复制下载的链接：https://repo.mysql.com//mysql80-community-release-el9-5.noarch.rpm
②查看本地仓库并下载安装
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# vim /rpm.repo
[baseos]
name=baseos
baseurl=/mnt/BaseOS
gpgcheck=0
[appstream]
name=appstream
baseurl=/mnt/AppStream
gpgcheck=0
[root@localhost yum.repos.d]# rpm -i https://repo.mysql.com//mysql80-community-release-el9-5.noarch.rpm
警告：/var/tmp/rpm-tmp.v6x1sA: 头V4 RSA/SHA256 Signature, 密钥 ID 3a79bd29: NOKEY

[root@localhost yum.repos.d]# dnf install mysql-server -y
③测试
[root@localhost yum.repos.d]# systemctl start mysqld
[root@localhost yum.repos.d]# systemctl start mysqld
[root@localhost yum.repos.d]# grep password /var/log/mysqld.log
