Today Tuto Guide; How to Build your own Tezos Node for the active mainnet.


![Lego-Build-1.jpg](https://cdn.steemitimages.com/DQmeW5c2xb4BXXFQu7HoSnVB2DyMwJQRkbzPhDEW2asR3Cd/Lego-Build-1.jpg)

Server Ubuntu 18.04 (2Cores)(8Ram)(120SSD)

    ssh root@IP-SERVER

    screen -S update

    apt update

    apt upgrade

    apt-get install build-essential

    apt-get install -y patch unzip make gcc m4 git g++ aspcud bubblewrap curl bzip2 rsync libev-dev libgmp-dev pkg-config libhidapi-dev

    dpkg-reconfigure locales 

select (ALL) + (en_US.UTF-8)

Meanwhile is working

    CRTL+A+D


    passwd

    (New-Secure-Password-ROOT)


Add a new user for the Tezos node 

    useradd -m -g users -G sudo -s /bin/bash tacoalfa

    passwd tacoalfa

    (New-Secure-Password-tacoalfa)

Disable root login SSH and change the port 22

    vi /etc/ssh/sshd_config

  (  i ) for can write the file

Delete # and 22 port, and Root login not.

Setup Firewall for preventing easy hacker access 

    ufw status

    Status: inactive

    ufw default allow outgoing

    ufw default deny incoming

    ufw default allow 56666

    ufw default allow 9732

    ufw enable

    ufw status

Back to screen and see if the update is finished and exit the screen.

    screen -r

    exit

If need restarts the server or just close the ssh session.

    reboot now

After 2 minutes or so connect again to the server new user new port.

    ssh -p 56666 tacoalfa@IP-SERVER

Now let's Install Tezos

Opam install

    wget https://github.com/ocaml/opam/releases/download/2.0.0-rc4/opam-2.0.0-rc4-x86_64-linux


    sudo mv opam-2.0.0-rc4-x86_64-linux /usr/local/bin/opam

    sudo chmod a+x /usr/local/bin/opam

    opam init --compiler=4.06.1

Yes and Yes

![Screenshot from 2018-09-23 22-19-25.png](https://cdn.steemitimages.com/DQmf4zL2kFJRaRVT69HpzDy8JeqjpbBrMFjTetqdiLNKiQT/Screenshot%20from%202018-09-23%2022-19-25.png)

    eval $(opam env)

    git clone -b mainnet https://gitlab.com/tezos/tezos.git

    cd tezos

    make build-deps

![Screenshot from 2018-09-23 22-20-57.png](https://cdn.steemitimages.com/DQmfXQu79g84pFXGP2pk6MHuLZd6iCfgyH1AZLvjjCyne3h/Screenshot%20from%202018-09-23%2022-20-57.png)

    YES

    eval $(opam env)

    make

    ./tezos-node identity generate 26.

Generating a new identity... (level: 26.00)

Tezos is finally installed and ready for the run.

![Screenshot from 2018-09-23 22-23-54.png](https://cdn.steemitimages.com/DQmXf6bdMHXEHn5KY41jJuYAJAmGhDp1jY8WvYciUS9VZEm/Screenshot%20from%202018-09-23%2022-23-54.png)

Open new screen for run Tezos node.

    screen -S mytezosnode

    ./tezos-node run --rpc-addr 127.0.0.1:8732 --connections 10

Now the node start to sync the Blockchain from the scratch

CRTL+A+C (new screen)
CRTL+A+N (switch between  screens)

In the new screen

   ./tezos-client get timestamp

Last block sync in your node is 

2018-09-23T20:26:40Z


when the node is synced the screen with the logs like the pic

![Screenshot from 2018-09-23 20-54-31.png](https://cdn.steemitimages.com/DQmaNtyLHwvdA6jvS6GyjpTYfSzidAFvzF7emgkemFFDXXW/Screenshot%20from%202018-09-23%2020-54-31.png)

Now can exit the screen session (CRTL + A + D) and back other time ( screen -r), the service is running meanwhile close ssh or lost the connections to the server. Remember for switch between  screens (CRTL+A+N)


Well here ok? Congratulations the Tezos node its alive! 

Now just relax, XTZ moon is coming.
