Centos8裝mysql的時候出現以下錯誤：
搜到的解決方法是：
sudo yum install compat-openssl10
結果又報了新的錯
解決這個新的錯的方法如下：
修改 /etc/yum.repos.d/CentOS-Linux-Base.repo，CentOS-Linux-AppStream.repo，CentOS-Linux-Extras.repo
修改如下：
注釋mirrorlist，把baseurl取消注釋並修改為阿里雲鏡像地址，注意是：$releasever-stream
# CentOS-Linux-Base.repo
[BaseOS]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/BaseOS/$basearch/os/
baseurl=https://mirrors.aliyun.com/centos/$releasever-stream/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
# CentOS-Linux-AppStream.repo
[AppStream]
name=CentOS-$releasever - AppStream
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/AppStream/$basearch/os/
baseurl=https://mirrors.aliyun.com/centos/$releasever-stream/AppStream/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
# CentOS-Linux-Extras.repo
[extras]
name=CentOS-$releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/extras/$basearch/os/
baseurl=https://mirrors.aliyun.com/centos/$releasever-stream/extras/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
修改之后清緩存，制作元數據緩存
# 清除所有緩存文件
yum clean all
# 制作元數據緩存
yum makecache
再次嘗試安裝，成功！
結果運行sudo rpm -ivh mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm還是出錯
解決方法如下：
sudo yum install compat-openssl10
好家伙 又出了另一個錯
解決依賴問題的辦法：
//openssl
//libcrypto.so.10
sudo yum -y install openssl
//libaio
//ibcrypto.so.10
sudo yum -y install libaio
//ncurses-compat-libs
//libncurses.so.5
sudo dnf install ncurses-compat-libs
//numactl
//libnuma.so.1
sudo yum install -y numactl
//perl
sudo yum install -y perl
再繼續安裝mysql就沒問題了
