一、仓库安装

[root@localhost ~]# rpm -ivh  https://repo.mysql.com//mysql80-community-release-el9-1.noarch.rpm

1、查看文件 

2、下载安装包

 [root@localhost ~]# dnf install mysql-server -y

 

[root@localhost ~]# systemctl start mysqld
[root@localhost ~]# systemctl status mysqld

3、 查看Mysql登录密码

[root@localhost ~]# cat /var/log/mysqld.log 

[root@localhost ~]# grep password /var/log/mysqld.log 

4、登录Mysql

[root@localhost ~]# mysql -uroot -p'dlKmpqd;K0#2'

5、 修改密码

mysql> alter user root@localhost identified by 'Admin123!';

6、重新登录

登录之后必须先修改用户密码,默认密码策略要求密码至少包含一个大写字母、一个小写字母、一位数字和一个特殊字符，并且密码总长度至少为8个字符。

[root@localhost ~]# mysql -uroot -pAdmin123!

7、查看数据库

mysql> show databases;

 8、读表命令

mysql> select *  from mysql.user;

 mysql> select user,host,authentication_string from mysql.user;

 9、卸载数据库软件

[root@localhost ~]# dnf remove mysql-server -y

 [root@localhost ~]# rpm -e mysql80-community-release 

[root@localhost ~]# rm -rf /var/lib/mysql/ /var/log/mysqld.log

二、本地安装

1、创建mysql文件夹

[root@localhost ~]# mkdir mysql        //创建mysql文件夹

[root@localhost ~]# cd mysql/            //进入该文件夹

2、下载安装包

[root@localhost mysql]# wget  https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.32-1.el9.x86_64.rpm-bundle.tar

 3、解压缩包

[root@localhost mysql]# tar xf mysql-8.0.32-1.el9.x86_64.rpm-bundle.tar  

4、安装所需要的依赖包

[root@localhost mysql]# dnf localinstall  mysql-community-server-8.0.32-1.el9.x86_64.rpm \
> mysql-community-client-8.0.32-1.el9.x86_64.rpm \
> mysql-community-common-8.0.32-1.el9.x86_64.rpm \
> mysql-community-icu-data-files-8.0.32-1.el9.x86_64.rpm \
> mysql-community-client-plugins-8.0.32-1.el9.x86_64.rpm \
> mysql-community-libs-8.0.32-1.el9.x86_64.rpm

5、重启mysql

[root@localhost mysql]# systemctl start mysqld
[root@localhost mysql]# systemctl status mysqld 

6、查看mysql密码

 [root@localhost mysql]# grep password /var/log/mysqld.log

 [root@localhost mysql]# mysql -uroot -p'Oh/2oTpyqHdw'

 7、修改密码

mysql> alter user root@localhost identified by 'Admin123';

完成！！！

8、卸载 数据库安装包

#查看数据库安装包

[root@localhost mysql]# rpm -qa | grep mysql
#卸载

[root@localhost mysql]# rpm -evh mysql-community-server-8.0.32-1.el9.x86_64 

[root@localhost mysql]# rpm -evh mysql-community-client-plugins-8.0.32-1.el9.x86_64 mysql-community-common-8.0.32-1.el9.x86_64 mysql-community-libs-8.0.32-1.el9.x86_64 mysql-community-client-8.0.32-1.el9.x86_64 mysql-community-icu-data-files-8.0.32-1.el9.x86_64 

 [root@localhost mysql]# rm -rf /var/lib/mysql/ /var/log/mysql.log

三、容器安装

1、卸载容器

[root@localhost ~]# yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine

2、下载安装包

[root@localhost ~]# dnf install -y yum-utils device-mapper-persistent-data lvm2

3、添加阿里云仓库

 [root@localhost ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

4、查看仓库路径

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ll

5、使用sed命令将下载路径更换成阿里云路径

[root@localhost ~]# sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo

6、安装docker-ce

[root@localhost ~]# dnf install docker-ce --allowerasing -y

7、启动docker服务

[root@localhost yum.repos.d]# systemctl start docker
[root@localhost yum.repos.d]# systemctl  status docker

 

 8、测试docker是否正常使用

#访问容器数据库

[root@localhost ~]# docker run --name mysqltest -e MYSQL_ROOT_PASSWORD=123456 -d mysql

9、进入dockers，登录mysql

[root@localhost ~]# docker ps

#进入mysql
[root@localhost ~]# docker exec -it mysqltest /bin/bash

#设置密码
bash-4.4# mysql -uroot -p123456
Enter password: 
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
4 rows in set (0.00 sec)

mysql> exit
Bye
bash-4.4# exit
exit

四、源码安装

1、建立本地源

[root@kongd ~]# mkdir /media/cdrom

#将本地光盘挂载至本地目录/media/cdrom下
[root@kongd ~]# mount /dev/cdrom / media/cdrom

[root@kongd ~]# cat /etc / yum.repos.d/rhel9.repo

[RHEL9-Baseos]
name=RHEL9-Baseos
baseur1=file : / / / media/cdrom/Baseos

gpgcheck=0
#apgcheck=1       #如果gpgcheck为1，需要写秘钥文件路径
#gpgkey=file : / / /etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial

[RHEL9-Appstream]
name=RHEL9-Appstream
baseur1=file: / / / media/cdrom / Appstream

gpgcheck=0

#gpgcheck=1
#gpgkey=file :/ l/etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficia7

[root@kongd ~]# yum repolist
#验i证能否装包成功
[root@master ~]# yum insta11 bind-utils -y
 

2、建立网络源

    阿里云网络源，aliyun的镜像站：https;//mirrors.aliyun.com/

[root@localhost yum.repos.d]# cat aliyun.repo

[aliyun-app]
name=aliyun-appsteam
baseurl=https : //mirrors.aliyun.com/centos-stream/9-stream/AppStream/x86_64/os

gpgcheck=0
[aliyun-base]
name=aliyun-baseos
baseurl=https : / /mirrors.aliyun.com/centos-stream/9-stream/BaseOS/x86_64/os/

gpgcheck=0
