Issues in starting MongoDB service I've installed MongoDB 3.0 in RHEL 6. From root user, I'm trying to start the mongo service but it is getting failed and the log file is not getting updated as well.


2015-10-13T09:53:26.133+0530 E NETWORK  [initandlisten] Failed to unlink socket file /tmp/mongodb-27017.sock errno:1 Operation not permitted
2015-10-13T09:53:26.133+0530 I -        [initandlisten] Fatal Assertion 28578
2015-10-13T09:53:26.133+0530 I -        [initandlisten]

***aborting after fassert() failure


The above is the last updated log.

I have another user 'oracle' from which also it is not starting.

I also tried running mongod --repair

It gives:

Things I have tried:


Deleting /tmp/mongodb-27017.sock but it says no file found with that name.
Changing the net.port in the config file to change the .sock file.
Setting unixDomainSocket : enabled: false
run these commands for ubuntu

sudo rm -rf /tmp/mongodb-27017.sock
sudo service mongod start
sudo ps aux | grep mongo
sudo kill
