【已解决】CentOS 7 安装MySQL80报错：pkgconfig(openssl) is needed by mysql-community-devel-8.0.28-1.el7.x86_64

当我们在执行rpm -ivh mysql-community-devel-8.0.28-1.el7.x86_64.rpm提示：

warning: mysql-community-devel-8.0.28-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY
error: Failed dependencies:
	pkgconfig(openssl) is needed by mysql-community-devel-8.0.28-1.el7.x86_64

这是由于缺少openssl-devel，使用如下命令安装一下就可以了：

yum install openssl-devel -y

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