:SELinux is preventing /usr/bin/mongod from 'open' accesses on the file /var/log/mongo/mongod.log.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that mongod should be allowed open access on the mongod.log file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep mongod /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 3 Miroslav Grepl 2012-09-24 06:51:57 EDT
It does not look like Fedora ships mongo-10gen-server-2.2.0-mongodb_1.

What does

# rpm -qf /var/log/mongo
Comment 4 Lukas Sembera 2012-09-24 07:32:32 EDT
Fedora doesn't ship with this version of MongoDB, it was installed from official 10gen MongoDB repository as described at http://docs.mongodb.org/manual/tutorial/install-mongodb-on-redhat-centos-or-fedora-linux/
Comment 5 Miroslav Grepl 2012-09-24 07:43:34 EDT
Ok, and what is your output of

# rpm -qf /var/log/mongo
Comment 6 Lukas Sembera 2012-09-24 07:53:08 EDT
# rpm -qf /var/log/mongo
  error: file /var/log/mongo: No such file or directory
Comment 7 Miroslav Grepl 2012-09-24 09:05:04 EDT

# chcon -t mongod_log_t /var/log/mongo/mongod.log

which will fix it for now.

Comment 10 Lukas Sembera 2012-09-25 07:33:42 EDT
I tested the update, but it unfortunately didn't help. The service is still not starting and I receive SELinux security alert with the possibility to report it as a bug. Do you need any more information?
Comment 11 Miroslav Grepl 2012-09-25 08:13:51 EDT
And if you execute

# restorecon -R -v /var/log/mongo/mongod.log
Comment 12 Lukas Sembera 2012-09-25 08:23:14 EDT
Still the same... but now it seems it has a problem with /var/lib/mongo, not /var/log/mongo/mongod.log anymore.
Comment 13 Miroslav Grepl 2012-09-27 12:59:30 EDT

restorecon -R -v /var/log/mongo
Comment 14 Lukas Sembera 2012-09-27 14:05:30 EDT
I tried that, too. Still not working.
Comment 15 Miroslav Grepl 2012-10-02 06:00:01 EDT
What does

# matchpathcon /var/log/mongo

# ls -dZ matchpathcon /var/log/mongo
Comment 16 Lukas Sembera 2012-10-02 06:05:17 EDT
# matchpathcon /var/log/mongo
> /var/log/mongo	system_u:object_r:mongod_log_t:s0

# ls -dZ matchpathcon /var/log/mongo
> ls: cannot access matchpathcon: No such file or directory
> drwxr-xr-x. mongod mongod system_u:object_r:mongod_log_t:s0 /var/log/mongo
Comment 17 Lukas Sembera 2012-10-02 06:06:31 EDT
But as I've already written earlier... the problem now seems to be with /var/lib/mongo, not /var/log/mongo.
Comment 18 Miroslav Grepl 2012-10-05 08:02:03 EDT
Ah, you are right, I missed it.

Comment 21 Lukas Sembera 2012-10-09 03:39:14 EDT
I've applied the update and now I'm getting:

Comment 22 Miroslav Grepl 2012-10-09 03:51:47 EDT
could you switch to permissive and collect all AVC msgs?

Comment 27 Fedora End Of Life 2013-07-04 02:17:46 EDT
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 28 Fedora End Of Life 2013-08-01 13:49:05 EDT
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
