Mongodb refuses to connect: shutting down with the code:100 - mongodb

Question

I have just installed Mongodb on my Ubuntu 18 LTS. When I follow the instructions according to the Mongodb Manual, I get some errors in step 3 which is apt update:
Err:11 http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 InRelease
403 Forbidden [IP: 143.204.209.210 80]
Err:12 https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 InRelease
403 Forbidden [IP: 143.204.209.210 443]
After much trying, I finally installed mongodb with this command,(I removed -org):
sudo apt-get install -y mongodb
after that, I started Mongodb without any errors:
sudo service mongodb start
then I checked the status and everything seems to be fine:
mongodb.service - An object/document-oriented database
Loaded: loaded (/lib/systemd/system/mongodb.service; enabled; vendor preset:

But the problem is when I type "mongod" in my Terminal, I encounter the error code:100 though I have my dbpath:

2020-04-16T11:14:05.161+0430 I CONTROL [initandlisten] shutting down with code:100
Does anyone have any idea what my problem is? I checked the previous talks but found nothing on this.
Another thing I have to report is that I use Sudo before mongod but get the same error with mongod.

Answer 1

While you could repair your existing installation, the log output indicates that you installed 3.6 which is 2 versions out of date (current version is 4.2), and is not even the most recent 3.6 release which is 3.6.17. So I suggest you follow the instructions again and prior to doing that, remove any existing files with names like /etc/apt/sources.list.d/mongodb-org-4.2.list that you may have and remove any installed MongoDB packages.

Finally I installed my Mongodb via changing my DNS because of sanctions problem. Now, I have my mongodb installed but when I type "mongod" in my Ubuntu terminal I get this:

And then when I re-run it with the commadand "sudo mongod" I encounter:

when I type "sudo systemctl status mongodb", I get this:
Unit mongodb.service could not be found.
But, when I enter this command I get the proper answer:
"mongo --eval 'db.runCommand({ connectionStatus: 1 })'"
MongoDB shell version v4.2.5
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("a24c786b-d161-4c3c-91bd-a55198d72505") }
MongoDB server version: 4.2.5
{
"authInfo" : {
"authenticatedUsers" : [ ],
"authenticatedUserRoles" : [ ]
},
"ok" : 1
}
Now, I was wondered what the problem could be?

Answer 3

I think I finally got my answer. Here there are some problems that may cause problems:
1.Uninstalling Mongodb completely is very important. You should remove every each of folders. For this, you can use Mongodb Uninstalling instructions.
For those who had the same problem as me, Forbidden access is sth for countries which are under sanctions and will not access to the targeted website unless you change your DNS or use Proxies. Otherwise you won't get access to anything.
3.If the previous step is met, then we can follow the instructions in Mongodb website in order to install your Mongodb.
**** An important thing is sometimes we need to change our IP connection in Configuration of Mongodb ****
Having Mongodb installed in your Computer, a reboot(restart) may be needed. After a restart the system may work correctly.
For running Mongodb in your Terminal type :
Mongod and if it didn't work, try "sudo mongod"
And finally we can enjoy our Mongodb.
Goodluck!
