Log file exists, mongod -f /data/mongod.conf doesn't pass test

MongoDB University M103: Basic Cluster Administration
#1

I created the mongod.conf file inside /data/ and I then run “mongod -f /data/mongod.conf” which gives the response “2019-08-26T02:01:01.755+0000 I CONTROL [main] log file “/data/logs/mongod.log” exists; moved to “/data/logs/mongod.log.2019-08-26T02-01-01”.”

I read on another post about this that the message about log file already existing can be ignored, but when I run the test “validate_lab_configuration_file” in another terminal window after connecting with “vagrant ssh” I still get “You need to start mongod with a configuration file.”

My /data/mongod.conf file looks like this (missing indentation due to formatting of this post, in the actual file it has indentation):

storage:
dbPath: “/data/db”
systemLog:
path: “/data/logs/mongod.log”
destination: “file”
net:
bindIp: “127.0.0.1,192.168.103.100”
port: 27000
security:
authorization: enabled

Hey @Thomas_J_Foydel_52714

I am not sure but maybe this could help.
https://docs.mongodb.com/manual/reference/configuration-options/index.html#systemLog.logAppend

After adding “logAppend: true” to the “systemLog” section of my mongod.conf and mongod.yaml (I’ve been trying both) I no longer get the “2019-08-26T02:01:01.755+0000 I CONTROL [main] log file “/data/logs/mongod.log” exists; moved to “/data/logs/mongod.log.2019-08-26T02-01-01”.” when I run “mongod -f /data/mongod.conf” or “mongod -f /data/mongod.yaml”.
But when I run the configuration test, I still get “You need to start mongod with a configuration file.”

Hi @Thomas_J_Foydel_52714,

Please check the following points and try to rerun the command:

  • Please ensure that you have privileges to write into the --dbpath directory
  • Make sure no other mongod running on same port(if any running from previous lab)
  • Please check the log file for more details on the error and also try giving the same directory path for log file as the “–dbpath”

@SUJANA_42894,
What is the path in your config file? And is mongod running?

PS: I’ve noticed that you’re always posting to old threads or threads started by other people. In the future, please create your own brand new thread.

my config file path is /data/mongod.conf
yes mongod is running

#8

Look inside your config file and show us a screenshot of the file path for the log file.

Hi @SUJANA_42894 can you see the difference?

Please also delete your last post. It’s against forum guidelines to post answers to labs.

Hi @SUJANA_42894,

As I can see you have completed this Lab so I am going to close this thread. If you have any other issue then please feel free to create another thread.
