Sharing Config Server is not working on the config

MongoDB University M103: Basic Cluster Administration
#1

I am following each step on the laboratory but I haven’t been to start the config server.
After creating the files: csrs_1.conf, csrs_2.conf, csrs_3.conf
And then start one of the server with:

mongod -f csrs_1.conf

I got his message:

vagrant@m103:~$ mongod -f csrs_1.conf
about to fork child process, waiting until server is ready for connections.
forked process: 1913
ERROR: child process failed, exited with error number 1
To see additional information in this output, start without the “–fork” option.

@AugustoAleGon let’s see the result of this:
ps -ef | grep mongo

Also, let’s see one of the config files.

#3

@007_jb The result is: ps -ef | grep mongo
vagrant 1998 1 1 21:48 ? 00:00:01 mongod -f csrs1.conf vagrant 2154 1883 0 21:49 pts/0 00:00:00 grep --color=auto mongo

config files are:
sharding:
clusterRole: configsvr
replication:
replSetName: m103-csrs
security:
keyFile: /var/mongodb/pki/m103-keyfile
net:
bindIp: localhost,192.168.103.100
port: 26001
systemLog:
destination: file
path: /var/mongodb/db/csrs1/mongod.log
logAppend: true
processManagement:
fork: true
storage:
dbPath: /var/mongodb/db/csrs1

What I see, it is like the folder csrs2, csrs3 are not seen in the root directory. Any linux trick for this case?

#5

The first one is already running. Try kicking off the second and third with mongod.

#6

And just make sure that the directories and port are not conflicting with each other.

#7

Finally I could solve the problem. It was more related to ubuntu manipulation directory more than mongod config.
Because my problem was that the folder that I created in var/mongodb/db/csrs1 are not available from my root directory. I did the following, in the root directory I use the following command:
sudo mkdir /var/mongodb/db/csrs1
sudo mkdir /var/mongodb/db/csrs2
sudo mkdir /var/mongodb/db/csrs3
Then I enable the permissions using the following commands:
sudo chown vagrant:vagrant /var/mongodb/db/csrs1
sudo chown vagrant:vagrant /var/mongodb/db/csrs2
sudo chown vagrant:vagrant /var/mongodb/db/csrs3

And then finally I can start successfully the config server replica set.
Also don’t forget the in the path use / as the initial root.

Good job! :+1:

Suggest you give vagrant access to the mongodb folder for future labs:
sudo chown vagrant:vagrant /var/mongodb/
