CentOS 8 Stream环境下通过yum安装Mysql

1.在Mysql下载页面MySQL :: Download MySQL Community Server页尾

点击 “MD5 checksums and GnuPG signatures” 进入下一页面

2.打开下载yum repo文件页面 (MySQL :: Download MySQL Yum Repository)

3.点击"DownLoad"按钮，打开下载页面，

4.获取链接地址,进入平台，

wget https://dev.mysql.com/get/mysql84-community-release-el8-1.noarch.rpm

5.在使用yum时，如报如下错误

6.更换国内yum镜像源

常见的几个yum源

阿里源：阿里巴巴开源镜像站-OPSX镜像站-阿里云开发者社区

腾讯源：腾讯软件源

网易源：欢迎访问网易开源镜像站

清华源：清华大学开源软件镜像站 | Tsinghua Open Source Mirror

华为源: https://mirrors.huaweicloud.com/

但网易源与清华源在默认路径下找不repomd.xml文件，

所以，这里简单配置成阿里云和腾讯云：

先备份

mv yum.repos.d yum.repos.d_backup
mkdir yum.repos.d
cd yum.repos.d

创建腾讯源

touch tencent-Centos-Stream-8.repo

编辑入如下内容

[BaseOS]
name=BaseOS -tencent
baseurl=https://mirrors.cloud.tencent.com/centos/8-stream/BaseOS/x86_64/os/
enabled=1
gpgcheck=0
​
[Appstream]
name=Appstream -tencent
baseurl=https://mirrors.cloud.tencent.com/centos/8-stream/AppStream/x86_64/os/
enabled=1
gpgcheck=0
​
[Extras]
name=Extras -tencent
baseurl=https://mirrors.cloud.tencent.com/centos/8-stream/extras/x86_64/os/
enabled=1
gpgcheck=0
​
[PowerTools]
name=PowerTools -tencent
baseurl=https://mirrors.cloud.tencent.com/centos/8-stream/PowerTools/x86_64/os/
enabled=1
gpgcheck=0

创建阿里源

touch aliyun-Centos-Stream-8.repo

配置：

[baseos]
name=CentOS Stream $releasever - BaseOS
baseurl=http://mirrors.aliyun.com/$contentdir/$stream/BaseOS/$basearch/os/
gpgcheck=0
enabled=1
​
#additional packages that may be useful
[extras]
name=CentOS Stream $releasever - Extras - mirrors.aliyun.com
baseurl=http://mirrors.aliyun.com/$contentdir/$stream/extras/$basearch/os/
gpgcheck=0
 
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS Stream $releasever - Plus - mirrors.aliyun.com
baseurl=http://mirrors.aliyun.com/$contentdir/$stream/centosplus/$basearch/os/
gpgcheck=0
enabled=0
 
[PowerTools]
name=CentOS Stream $releasever - PowerTools - mirrors.aliyun.com
baseurl=http://mirrors.aliyun.com/$contentdir/$stream/PowerTools/$basearch/os/
gpgcheck=0
enabled=0
​
​
[AppStream]
name=CentOS Stream $releasever - AppStream - mirrors.aliyun.com
baseurl=http://mirrors.aliyun.com/$contentdir/$stream/AppStream/$basearch/os/
gpgcheck=0

安装Mysql的yum repo

yum -y localinstall mysql84-community-release-el8-1.noarch.rpm

更新缓存

yum clean all && yum makecache

禁用Centos stream 8 自带的Mysql

yum module disable mysql

安装MySQL、

yum install -y mysql-community-server

报错误

导入的密钥没有公钥，错误的公钥？
mysql-community-client-8.0.40-1.el8.x86_64.rpm 的公钥没有安装.

更换MySQL的版本

gpg --import mysql_pubkey.asc

netstat -tulnp | grep 3306

docker ps -q | xargs docker stop    //停止所有的docker
