无法在RHEL7 VM上安装cyrus

Question

我有一个RHEL7 vm设置，并且正在尝试运行mongodb。安装后，我得到：

--> Finished Dependency Resolution
Error: Package: mongodb-database-tools-100.3.0-1.x86_64 (MongoDB)
           Requires: cyrus-sasl
Error: Package: mongodb-database-tools-100.3.0-1.x86_64 (MongoDB)
           Requires: cyrus-sasl-plain
Error: Package: mongodb-database-tools-100.3.0-1.x86_64 (MongoDB)
           Requires: cyrus-sasl-gssapi
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
[vagrant@rhel7 yum.repos.d]$ mongo -v
-bash: mongo: command not found
[vagrant@rhel7 yum.repos.d]$ mongod -v
-bash: mongod: command not found
[vagrant@rhel7 yum.repos.d]$ mongod
-bash: mongod: command not found
[vagrant@rhel7 yum.repos.d]$ sudo yum install cyrus-sasl

我试着下载cyrus并手动安装它，但是我没有找到任何关于如何正确地这样做的信息。任何帮助都将不胜感激。

Answer 1

正如信息所述：

此系统未在权限服务器上注册。您可以使用订阅管理器注册。

您要么没有为RHEL订阅付费，要么没有为订阅正确地配置您的系统。因此，您的系统无法安装任何软件包。

修复您的系统或使用像CentOS这样的操作系统，不需要支付操作费用。
