Why MongoDB does not start in Fedora ? [SOLVED]

Hello guys,

Today I want to share with you how to easily make MongoDB work in Fedora. Recently, while moving to F19 I have faced the issue when my Mongo does not start. What I mean by does not start ?

[aspektor@localhost routes]$ mongo
MongoDB shell version: 2.4.3
connecting to: test
Tue Jun 11 16:07:26.273 JavaScript execution failed: Error: couldn't connect to server at src/mongo/shell/mongo.js:L112
exception: connect failed

Also when I try to start service:

[aspektor@localhost routes]$ service mongod start
Starting mongod (via systemctl):  Failed to issue method call: Access denied

The main thing here is:


I even put it in green, because green  suppose to be the  most relaxing colour :))))

The problem lies in SELinux , disallowing access to MongoDB. I have tried setting SELinux to permissive, and one time it worked, but it didn’t the other time. And frankly saying, you don’t want your SELinux to be in Permissive mode.

So what you need to do is to create a policy allowing Mongo to access your system.

SELinux provides you with these 2 commands:

[root@localhost routes]$ grep mongod /var/log/audit/audit.log | audit2allow -M mypol
******************** IMPORTANT ***********************
To make this policy package active, execute:

semodule -i mypol.pp

[root@localhost routes]$ semodule -i mypol.pp1

If you are still curious where did I get this commands from – I got them right from SELinux  (image clickable):

Mongo SELinux

After setting the new policy that allow mongo, just try to start it again:

[root@localhost routes] exit
[aspektor@localhost routes]$ mongo
MongoDB shell version: 2.4.3
connecting to: test

Let me know if it worked for you!

    hi, i ran the command “grep mongod ……. mypol” , it said: permission denied.
    so i used sudo with the command, now it says: Nothing to do.
    and the problem persists.. 😦
