【已解决】CentOS 7 安装MySQL80报错：mysql-community-icu-data-files = 8.0.28-1.el7 is needed by mysql-community

当我们在执行rpm -ivh mysql-community-server-8.0.28-1.el7.x86_64.rpm的时候提示：

warning: mysql-community-server-8.0.28-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY
error: Failed dependencies:
	mysql-community-icu-data-files = 8.0.28-1.el7 is needed by mysql-community-server-8.0.28-1.el7.x86_64

这是由于需要在安装server之前需要装一下icu-data-files，执行如下命令即可安装icu-data-files：

rpm -ivh mysql-community-icu-data-files-8.0.28-1.el7.x86_64.rpm

接着再执行rpm -ivh mysql-community-server-8.0.28-1.el7.x86_64.rpm就不会报错了
