I'm not able to install the mongos RPM. I get the following error and I'm not sure what yum/rpm command to run to download the library it needs. I'm installing 3.2.12-1 onto Red Hat Enterprise Linux Server release 7.4 (Maipo).

[u060dchd401ainstall@u060dchd401a mongodb-enterprise-3.2.12]$ sudo rpm -ivh mongodb-enterprise-mongos-3.2.12-1.el5.x86_64.rpm
warning: mongodb-enterprise-mongos-3.2.12-1.el5.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID ea312927: NOKEY

I tried running this but it didn't seem to help.
