{{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())"
