Mongodb connected failed in tls native installation

[Lin__Joey]

This week I upgraded the TLS from that contained in EIS2.1.1 to EIS2.2.

I also upgraded OpenVino to 2020.2.

This time, I have remoted agent and dispatcher connected without error, but the Mongodb connected failed.

And the tls localhost:8080 webpage could not work, either.

What will be possible reasons for this issue? Should I need to use Docker version instead?

Your expertise will be highly appreciated!

Hi Joey,

According to your follow-up email, TLS related services, such as mongod and perhaps others , are in an inactive state. Can you please do a "sudo systemctl daemon-reload" and see the services can start correctly?

If this doesn't work, please help us understand the steps you took to install and set up TLS. As part of tls/Setup/setup_TLS.sh, steps were taken to install, set up, and start mongod. Let's find out what went wrong.

Regards,

Jia-Shing

Dear Jia-shing;

Run “sudo systemctl daemon-reload”, but the mongod service still not available

My installation followed the steps in 1_Installation.md and 2_NativeDevelopment.md

I tried to run tls/Setup/setup_TLS.sh again, it succeed.

Yet, mongod still not running, and the connection failed

Could you please explain more about how to set up and start mongod?

Thank you in advance,

Joey

Hi Joey,

During your setup, did you see any error? Can you capture the installation logs and attach it here?

If you look at setup_TLS.sh, there is the following

echo "Setup MongoDB PPA Repository"
wget -qO - https://www.mongodb.org/static/pgp/server-4.0.asc | sudo -E apt-key add -
echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
sudo -E apt-get update
sudo -E apt-get install -y mongodb-org
sudo systemctl enable mongod
sudo systemctl start mongod
 

These lines are supposed to install mongodb, enable and start the daemon. Do you see /etc/systemd/system/multi-user.target.wants/mongod.service and /lib/systemd/system/mongod.service?

By the way, do you have any Docker container running (docker ps)? Is your TCP port 27017 in use? I am wondering if there is a port conflict that prevented mongod from running.

Hi, Jia-Shing:

You are right. The log shows error when installing mongodb. The error message lists as below:

Hi Joey,

Your device is missing the public key for mongodb-org. If you do "sudo -E wget -qO - https://www.mongodb.org/static/pgp/server-4.0.asc | sudo -E apt-key add -" from the commandline, do you see any error? If this works, run the installation scripts again. If it doesn't, please check your proxy settings.

Regards,

Jia-Shing

[Lin__Joey]

Dear Jia-Shing:

The network seems fine. However, the public key seems not working. Please check the message after running setup.

/home/joeylin/tls # sudo -E wget -qO - https://www.mongodb.org/static/pgp/server-4.0.asc | sudo -E apt-key add -

OK

Hi Joey,

I'm curious, why is your setup installing mongodb 3.4 while mine is doing 4.0? Are you installing TLS from EIS 2.2 or 2.1.1? Below is some description of what the script lines do:

wget -qO - https://www.mongodb.org/static/pgp/server-4.0.asc | sudo -E apt-key add -   --> This line added the public key for mongodb-org v4.0.
echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list    --> This line adds the mongodb 4.0 repository to the list.
sudo -E apt-get update --> updates package list
sudo -E apt-get install -y mongodb-org  --> expected to install the latest available, which is 4.0
sudo systemctl enable mongod
sudo systemctl start mongod
 

Please double check.

Regards,

Jia-Shing

[Lin__Joey]

Hi, Jia-shing:

I uses the EIS2.2 and the script in the setup_TLS.sh do call to install mongodb 4.0.

Somehow the script manage to install 3.4 and failed. Please see the installation log for details.

By the way, I am using Ubuntu 16.04, and will be the version of python affect the installation version selection?

Hi Joey,

Based on the log you provided, I’m guessing you have installed mongodb 3.4 on this device in the past.

If you do “apt-key list”, you likely will see a public key for 3.4 and another one for 4.0. If you do “ls -la /etc/apt/sources.list.d/”, there likely is a mongodb-org-3.4.list in addition to mongodb-org-4.0.list. It’s safe to remove the file mongodb-org-3.4.list.

According to https://docs.mongodb.com/v4.0/tutorial/install-mongodb-on-ubuntu/, you will need to manually modify setup_TLS.sh and replace the 'echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list' line with 'echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list' for Ubuntu 16.04. 

Please do note that EIS is validated with Ubuntu 18.04 and we recommend using 18.04.

Hi, Jia-shing:

The issue has been resolved.

I checked the /etc/apt/sources.list.d/, and I saw mongodb3.4.list.

I removed it and tried the setup_TLS.sh again after modifying with the line you provided for ubuntu16.04 LTS

'echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list' line with 'echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list'

The mongodb 4.0 is setup and running. 

Thank you so much for your quick response, and supports,

Joey

Hi Joey,

Glad to know your issues are resolved. Have fun with EIS and TLS! :)
