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

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

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

eval $(opam env)

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

cd tezos

make build-deps

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.

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

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.
