linux安装mysql

1.wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.31-1.el8.x86_64.rpm-bundle.tar
2.解压 tar -xvf /usr/local/mysql-8.0.31-1.el8.x86_64.rpm-bundle.tar -C /usr/local/mysql_package
3.依次执行：
rpm -ivh mysql-community-common-8.0.31-1.el8.x86_64.rpm

rpm -ivh mysql-community-client-plugins-8.0.31-1.el8.x86_64.rpm

rpm -ivh mysql-community-libs-8.0.31-1.el8.x86_64.rpm

rpm -ivh mysql-community-client-8.0.31-1.el8.x86_64.rpm

rpm -ivh mysql-community-icu-data-files-8.0.31-1.el8.x86_64.rpm

rpm -ivh mysql-community-devel-8.0.31-1.el8.x86_64.rpm
这个很有可能报错

解决办法:更新镜像源
执行以下命令：
sed -i ‘s/mirrorlist/#mirrorlist/g’ /etc/yum.repos.d/CentOS-*
sed -i ‘s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g’ /etc/yum.repos.d/CentOS-*
yum makecache
yum update -y

再次安装：

rpm -ivh mysql-community-server-8.0.31-1.el8.x86_64.rpm
