yum provides krb5-config

执行安装：yum install krb5-devel-1.15.1-8.el7.x86_64
提示：
error: Failed dependencies:

到https://pkgs.org/搜一下这个几个安装包，逐个安装即可，安装过程中可能会提示依赖未安装。
针对安装过过程种的错误提示Failed dependencies，
可以使用命令
rpm -ivh libcom_err-devel-1.42.9-13.el7.x86_64.rpm --nodeps --force
rpm -ivh libselinux-devel-2.5-14.1.el7.x86_64.rpm --nodeps --force
rpm -ivh libkadm5-1.15.1-34.el7.x86_64.rpm --nodeps --force
rpm -ivh krb5-devel-1.15.1-8.el7.x86_64.rpm --nodeps --force
安装完后重新运行即可。
2. fatal error: 'openssl/e_os2.h' file not found
出现这个异常的原因是没有找到'openssl下的*.h文件，可以查看/usr/include/openssl/e_os2.h
是否存在，如果没有openssl目录应该就是没有安装openssl
CentOS、RedHalt执行yum install openssl-devel
ubuntu 执行sudo apt-get install libssl-dev
