{{Note box|If you start mongo like this you will run mongo as root.
 +
When mongo later tries to start automatically it may fail because it will be started as the mongod user and won't be able to access the DB files.}}

The link to mongodb is not necessary.

As far as I can see, the link above to mongodb is not necessary.
    
It may need this to set on and off correctly in other service levels:

{{Warning box| Complete work in progress - here be Dragons!}}
 +
 +
===Install===
 +
Use the above method to add the repo and then:
 +
 +
yum --enablerepo=mongodb install mongodb-org
 +
 +
Mongo will automatically create a symlink so currently there is no way to enable/disable it apart from manually. Once Koozali SME has some more systemd tools we can use DB keys etc.
 +
 +
Created symlink from /etc/systemd/system/multi-user.target.wants/mongod.service to /usr/lib/systemd/system/mongod.service
 +
 +
To enable/disable this just use:
 +
 +
systemctl {en|dis}able mongodb
 +
 +
And to start stop
 +
 +
systemctl {start|stop|restart} mongodb
 +
 +
===Vaporise or reinitialise the database===
 +
 +
{{Warning box| This will totally and utterly vaporise your data. Got a backup?? You have been warned}}
 +
 +
Remove the directory contents:
 +
 +
rm -rf /var/lib/mongo/*
 +
 +
Or remove the entire directory and recreate it with the correct ownership:
 +
 +
rm -rf /var/lib/mongo
 +
mkdir -p /var/lib/mongo
 +
chown -R mongod:mongod /var/lib/mongo
 +
 +
If you have a replicaset set in /etc/mongod.conf make sure you initiate it:
 +
 +
mongo --eval "printjson(rs.initiate())"
 +
