From YouTube: Setting up a Mina Protocol node on Linux

Description

A short step-by-step guide about how to set up a Mina Protocol node on a Linux operating system.

A

Yeah hi there it's been a long time since the last video that I posted to youtube and in the meantime some fox asked me like to make a quick demo on how to set up a mina block producer.

A

You will see that it is really easy to do if you have the proper guidance and you do the things step by step, as they are meant to be done, always consider checking out the mina website for the latest for latest uh installed instructions, since uh some of the packages uh are updated frequently, and it might be that the version that we're using here yeah might be deprecated soon.

A

But even if the release changes, the main steps are more or less the same across the different versions. So yeah this will be for sure useful in the future. As well as you can see here, I have a text file with the instructions that I'm going to use and um yeah I'm gonna post them. Together with the video I am running uh ubuntu 2004, and that means that uh I have to install some dependencies, these uh three libraries.

A

So what we're gonna do is uh create a temporary folder for the dependencies. Then we're gonna update our repositories, then install these three dependencies and then remove them.

A

Yeah, probably here nothing's gonna happen because uh yeah I have already installed those three libraries before but uh yeah. That's it there's nothing else to do.

A

So once those three dependencies are installed, we're gonna, add the mina repo and then we're gonna update our packages.

A

We add the ripper first and then retrieve the latest packages from there.

A

And then the next thing to do is install mina itself. We are installing release 1.2.2.

A

As you can see, I'm running every single command where needed as sudo, that is, a super user, but with a plane, user.

A

And then the next thing to do is install the package to generate keys.

A

So we installed first mina daemon itself. That was the previous step and the current one has been installing the keeper generator.

A

So the next thing to do is make a folder for the keys and give it the proper permissions for security reasons.

A

So we create the keys folder inside of our home folder, and then we change its permissions.

A

As you can see, the folder is readable. Just for this. All for this car end user yeah. Of course root user can read it as well, but uh what we don't want is other users of the same box to be able to access to access that folder.

A

So the next thing to do his generator keeper with this command here minor, generate keeper and then the path to the folder, where the keys are going to be stored, we're gonna run it and then it is going to ask for a password.

A

You have to write this password down and save it on a safe place, and here we are, that is our block producer, key okay, that is the one that we are going to be using in this box.

A

So I'm gonna save it block producer key. It is the public key, so there's no trouble in saving it here and then we continue now that the keeper is generated.

A

We have to import it into mina, so that mino knows that that account exists.

A

And this is the command, you know, accounts import and then the path to the keys, and then it asks for the password and then on a second step. It asks for the password that we want to use for this key on this box. I'm gonna use the same, but you can you can use a different one. If you want so accounts, not imported, you can even check it out with mino accounts list, and here is okay.

A

So, let's move on.

A

Now we have to create a a file with the password of the keys that we've just generated because they are needed and the for minidemon to work.

A

A

And here it is, in this case the password that I'm using yeah it's an abstract one. It is the password that import keys command asked for on the second step. That is the password that we are using that key with in this box.

A

And now that that environment file is created.

A

We're gonna create a service file.

A

Yeah, in this case, I'm gonna make it a little bit different, since I'm some of the characters are being stricter. So this is the contents of the file and we created.

A

So it is a service file to be sure that the amino demon is started when the machine is run. So this is the user that is going to run the daemon its group, the working directory, where our environment file is the one that we've just created on the previous step, and then we see here some flags, the minimum block reward to be sure that we are not producing any yeah. We put any reward blocks. The magic sport and our plot producer puff key has to be the one that we've just created. I'm gonna.

A

Retrieve it block producer key.

A

Then I put it into the file.

A

And the graphql port it is needed, for example, for the uptime sidecar.

A

We can change the lock level to info if we want.

A

A

Address of the beers list and yeah, this is pretty it.

A

So note that the file is created.

A

We have to enable it.

A

And then we start it.

A

Now that the it is already started, we can check the logs of the of the system service.

A

And yeah this is it uh we can as well check inside of the folder where we are running mina inside of minnesota of minna dash config steps and locks are created as well.

A

So we can see that it is already starting.

A

Now we have to wait a while until midnight client status gives an answer. You see this is pretty normal on start, it is not gonna give an answer. You have to wait a bit and that is going to be the second part of the video, so I will switch it off a sec and then go back when uh yeah. Some minutes are gone, so that mean has already started.

A

So now that a couple of minutes have already passed, uh we can run my minor client status and then we see that the note is already put strapping.

A

Then it is going to change the starters to catch up and then in the end it's gonna show the synced status. So we're gonna wait uh some more minutes, so we can see that the node is running.

A

And uh yeah, as mentioned before after a time, the notes shows, with minor client status, that it is already catching up, finished, 118 and waiting for parent to finish 180.. Those numbers are going to change over time. You see now 160 to finish and yeah. Once this box already dealt with, then we will see that the note is already synced.

A

It will happen in about five minutes.

A

And yeah, as promised after a time we see that the note is on sync status and yeah. This is pretty it.

A

Thank you for watching and yeah open for questions anytime. Take care.
