Hello, i am trying to make the lab but i cant, i don’t know why please help
To me i can’t find some error…
This is my cluster status

}
}

And now the validate output
vagrant@m103:~$ validate_lab_initialize_local_replica_set

Client experienced a timeout when connecting to the database - check that mongod
processes are running on ports 27001, 27002 and 27003, and that the ‘m103-admin’
user authenticates against the admin database.

The ports are ok, the user too… included the location of the files /paths

vagrant@m103:~$ cat mongod-repl-1.conf
net:
bindIp: localhost,192.168.103.100
port: 27001
storage:
dbPath: /var/mongodb/db/1
systemLog:
destination: file
path: /var/mongodb/db/mongod1.log
logAppend: true
security:
authorization: enabled
keyFile: /var/mongodb/pki/m103-keyfile
replication:
replSetName: m103-example
processManagement:
fork: true

Does anyone knows what i am doing wrong?
Best regards

Are the ports correct?
Are you able to login with the user?
Please follow the steps as per your lab.Sometimes while copy config files from previous labs you may be using wrong values
Please double check

Hello, i used this to create the user
use admin
db.createUser({
user: “m103-admin”,
pwd: “m103-pass”,
roles: [
{role: “root”, db: “admin”}
]
})
and this string to connect to the cluster
mongo --host “m103-example/192.168.103.100:27001” -u “m103-admin” -p “m103-pass” --authenticationDatabase “admin”

and i think that is connecting ok …
including if you see the log… you can see the secondary nodes and they ports

vagrant@m103:~$ mongo --host “m103-example/192.168.103.100:27001” -u “m103-admin” -p “m103-pass” --authenticationDatabase “admin”

Is your replSetName correct?
Please check again
If you don’t follow lab requirements validation will fail
