Description
We are setting up a MongoDB server for the production environment on Amazon EC2 instance, but could not able to start the service. I've followed this documentation for setup. Here are the steps, I've taken for setting up the server:
Added following to `/etc/yum.repos.d/mongodb-org-3.0.repo`
[mongodb-org-3.0]
|
name=MongoDB Repository
|
baseurl=http://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.0/x86_64/
|
gpgcheck=0
|
enabled=1
|
And installed MongoDB 3.0.2 using `sudo yum install -y mongodb-org-3.0.2`
Created three partitions for data, journal & log:
sudo mkdir /mongo
|
sudo mkdir /mongo/data
|
sudo mkdir /mongo/log
|
sudo mkdir /mongo/journal
|
Created file system for three separate partitions:
sudo mkfs.ext4 /dev/xvdb
|
sudo mkfs.ext4 /dev/xvdc
|
sudo mkfs.ext4 /dev/xvdd
|
Created entry in `fstab` for reboot:
echo '/dev/xvdb /mongo/data ext4 defaults,auto,noatime,noexec 0 0
|
/dev/xvdc /mongo/journal ext4 defaults,auto,noatime,noexec 0 0
|
/dev/xvdd /mongo/log ext4 defaults,auto,noatime,noexec 0 0' | sudo tee -a /etc/fstab
|
And mounted the partitions:
sudo mount /mongo/data
|
sudo mount /mongo/journal
|
sudo mount /mongo/log
|
Given the permissions and created link
sudo chown mongod:mongod /mongo/data /mongo/journal /mongo/log
|
sudo ln -s /mongo/journal /mongo/data/journal
|
Configured `ulimit` & read ahead settings as given in the documentation link above. Verified permissions and partitions:
[deployer@prod-mongo ~]$ df -h
|

|
drwxr-xr-x. 3 mongod mongod 4096 May 11 08:58 log
|
After changing the configurations inside `/etc/mongodb.conf`
logpath=/mongo/log/mongod.log
|
dbpath=/mongo/data
|
Also, changed the SELinux setting to `permissive`. Now when I'm doing: `sudo service mongod start`, I'm getting this error:
Starting mongod (via systemctl): Job for mongod.service failed. See 'systemctl status mongod.service' and 'journalctl -xn' for details.
[FAILED]
Further logging:
[deployer@prod-mongo ~]$ sudo systemctl status mongod.service

Kernal version from uname -a:

If I directly run the mongodb service from the normal user something like this: sudo mongod --config /etc/mongod.conf, then this service is starting properly but not as the system service?
I've followed various articles and blog posts and stackexchange answers, but didn't get any solution.
