mongodb does not start as installed

[jwoehr (Jack J. Woehr)]

None of the suggestions I have seen start mongodb once installed.

• sudo port load mongodb
• ​https://github.com/codeforamerica/ohana-api/wiki/Installing-MongoDB-with-MacPorts-on-OS-X
• ​https://gist.github.com/Olliebrown/32a48df35db9c0c5905a017f8a494acb

There seems to be no conf file installed, nor any instructions (other than the web links above) how or where to create. Having created such a conf file /opt/local/etc/mongodb/mongodb.conf and chown'ed it to _mongo:_mongo the program still exits silently.

INVALID ... Apologies ... Reading /opt/local/var/log/mongodb/mongodb.log I determined mongod was choking on a backlevel database.

• I deleted the /opt/local/var/db/mongodb
• Recreated the directory and chown'ed it to _mongo:_mongo
• sudo port load mongodb now works

Not sure if the manual step of creating the configuration was valid and that the created config is actually the one being used.

• Suggest some build-time message for the user informing the user where the config file should reside.
• Suggest some build-time message alerting user that db might have to be recreated.

Thank you for your help.
