Unable to start up mongod

[Alan]

Hi,

I have just upgraded mongodb from version 3.4 to 3.6.3, but now the mongo server won't start up.  When I try to start up the service with "sudo service mongod start", I get the following message. I'm running on Ubuntu 16.04.3 LTS.  Anyone please help.

Can you post your config file /usr/local/etc/mongod.conf ?

Hi Alan,

I suggest you to take a look to these two links and try to determine whats the deprecated/invalid config directive on your new 3.6 cluster:

https://docs.mongodb.com/manual/release-notes/3.6-compatibility/

https://docs.mongodb.com/manual/reference/command/setFeatureCompatibilityVersion/#view-fcv

Hope it helps,

Thank Jorge, I'll give it a try.

Jorge or anyone,

I've tried the two links Jorge suggested, but still having the same problem.  Please help.

but still having the same problem. Please help.

Hi Alan,

Please note that the deprecated options for HTTP Interface and REST API have been removed in MongoDB v3.6. This may be the cause of the mongod server unable to start up.

For more information about MongoDB 3.6 configuration file, please see Configuration Options.

I’d also suggest to check your mongod log file located in “/var/log/mongodb/mongod.log”.

You may also find Upgrade a standalone to 3.6 a useful reference.

Regards,
Wan.
