Mongodb v4.0 .2 installation on RHEL 7.1

[Raymond Chow]

I have been trying to install the community version 4.0.2 on RHEL 7.1. The instruction is vague and I hope someone might be able to give me a hand or two...  )).

Below is the error message-

# mongo

I removed it by following the uninstall instruction. When I re-install agaiin I get the following error:

]$ sudo yum install -y mongodb-org

Loaded plugins: langpacks

No package mongodb-org available.

Error: Nothing to do

This is the script:

$ cat mongod-org-4.0.repo 

[mongodb-org-4.0]

name=MongoDB Repository

baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/

gpgcheck=1

enabled=1

gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc

------------------------------------

How do I start troubleshooting? I have check /etc/var, there is no mongo directory. I can't even find the mongod.conf file. 

Any help to geet this up wouold be most appreciated.

Best,
Ray

Hi Raymond,

It looks like the mongodb-org-server package did not get installed as the repo is not setup correctly. Is your mongod-org-4.0.repo file in /etc/yum.repos.d/ ?

Do you see the repo listed as enabled in the output of: 

yum repolist all 

Best Regards,

Matt

Thanks Matt,

I look into the repo file and ran it one after another to see where it was failing. I got to the point where yum started to pull the packages. That is where it fails. Henceforth, I manually downloaded all the packages and use the rpm to install each package.

It is currently up and running. I was able to see the log files.

Thanks for the hint. It helps.
