As I've mentioned before, today I'm posting the instructions to get your own Google Cloud Server for free for $ 300 to spend, a free gift from Google.

What is a Virtual Private Server or VPS?

Consider that every ad you see on the internet for free or very cheap website hosting (ie your site's files), 90% of all these services have to do with a shared hosting server, that is, the same server (computer) hosts other clients inside (except you).

The reasons why many choose this simple hosting site are: 
1. Why it's so easy to use 
2. It's all pre-installed (email, ftp, databases etc) 
3. It's very cheap compared to a Virtual Private Server

But if we want to look at reality from another perspective:
1. You are using the same IP as other 100+ clients, which means you have the following risks:
   hacking, ddos attacks, blacklist ip, slow operation causing the server to crash every bit, 
   etc.
2. They may all be preinstalled, but how many times have you tried to add a wordpress add-on 
   for example to import 1000+ products into your e-shop and all of a sudden they stuck? 
   This is almost always the case when the add-on asks for more resources, memory, and so on, 
   and often depending on the hosting company you have to ask for and if they want they will 
   usually give it to you.
3. The myth that Shared Hosting is cheap does not apply, because of the limitations you 
   usually have to get a Gold package and that means you will spend at least $ 10- $ 14 
   a month, that is, $ 120-168 $ a year.

For this reason, slowly or quickly, it is time to start looking for the famous VPS.

In the past, VPS cost Cuckoo Aidoni, but today we have a lot of options, and not to be outdone, you can see the history of VPS on Google with a look.

One of the options for VPS is the Google Cloud Platform (Compute Engine) service where Google offers a $ 300 trial to use wherever you want.

I will enrich this post with more and more (easier) corrections in the future, as well as upload a video throughout the process. For the moment I quote that I have missed writing in my spare time and as always feel free to ask?)

    b) Write: chown -R www-data:www-data /var/www/html/tositesou.com

    j) at the bottom of the keyboard, press Ctrl + X, then press Y and then press Enter
    k) go to your domain's DNS Settings, which you will find at the provider where you purchased the domain (eg papaki.gr or godaddy.com etc))

    (see the picture and you will understand: https://drive.google.com/open?id=0B0-xSvKcaUZhNThjSHBZM0Y5VGs)
    l) On the console Write: sudo service apache2 restart
    m) Let's see if it's all done right, visit your domain in your browser, tositesou.com, logically Forbidden, of course you don't have any
    file inside, that's why.
12. To upload your website (IGNORE THE FILE MANAGER INSTALLATION ON THIS STEP, GO TO BOTTOM):
    a) Write: cd /var/www/html/
    b) Write: wget https://old.nicolaslagios.com/downloads/pafm.zip
    c) Write: unzip pafm.zip

    f) Write: chown -R www-data:www-data /var/www/html/pafm
    g) So to upload a website:
      g1) Visit File Manager at: http://ip.του.server.σου/pafm/pafm.php and upload to the correct folder
      g2) If you also want a database, visit: http://ip.του.server.σου/phpmyadmin
    Sign in and on the left click "New"
    Type a name and click Create
    (when you later ask WordPress for example database
    database name: database name, database host: localhost
    database user: root , database password: your password)
    h) Because you'll need them, here are some basic console commands here: https://pastebin.com/Fre59wAg
13. To connect email:
    a) Go to https://app.mailgun.com/app/dashboard , sign up
       sign in and go to the Domains tab
       click Add New Domains
       write mailgun.tositesou.com
       go to the dns settings of your domain as you did before and do exactly what the mailgun tells you
       once you do that, after 2 hours go back to the mailgun domains tab and click on the new domain you just
       put it down, click on the "Check DNS Records Now" button
    b) Write: sudo su -
       Write: umask 077
       Write: apt-get update && apt-get install postfix libsasl2-modules -y
              (select Local Only and press Enter, and then press Enter again)
       Write: nano /etc/postfix/main.cf
              If available, remove the push-button symbol from the front
              If not, add them
              If they exist and don't have a push-button symbol, then do nothing, go to the next step
# default_transport = error
# relay_transport = error

              Add the following lines to the same file:
relayhost = [smtp.mailgun.org]:2525
smtp_tls_security_level = encrypt
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous

              Finally press CTRL + X and immediately after Y and Enter
              to save and close
      Write: cat > /etc/postfix/sasl_passwd << EOF
             in the > that will open, write the following:
[smtp.mailgun.org]:2525 YOUR_SMTP_USERNAME:YOUR_SMTP_PASSWORD
             (you will find them by going to: https://app.mailgun.com/app/domains
             and clicking on the domain of interest)
             Note!!! Don't worry, whatever email you send through your server
             you will see the email you send, not the domain from which you get smtp access
      Write: Press Enter & then Write: EOF
             and press Enter
      Write: postmap /etc/postfix/sasl_passwd
      Write: ls -l /etc/postfix/sasl_passwd*
      Write: rm /etc/postfix/sasl_passwd
      Write: chmod 600 /etc/postfix/sasl_passwd.db
      Write: ls -la /etc/postfix/sasl_passwd.db
      Write: /etc/init.d/postfix restart

14. To connect via FTP (IGNORE THIS STEP GO TO BOTTOM)
    a) download the client machine filezilla client: https://filezilla-project.org
    b) download the tool "puttygen": https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
    c) run "puttygen" and press the button "Generate"
       then press "save private key" and save it somewhere you can remember it with whatever name you want, e.g. putty-key.ppk
       don't close the program yet
    d) go to the Google CLoud console: Compute Engine/Metadata
       in the second tab "SSH KEYS" click edit and then click on the add item and copy all the public key you made on
       "puttygen" and press save
    e) open filezilla and go to menu Edit/Settings and from the left panel choose SFTP and press Add Key File
       add the key file you save on step c and press OK
       Now to log in: Host: sftp://ip_tou_server_sou , username: από το puttygen put your key comment and click connect
       As you will see in the / home folder a subfolder has been created with your username
       go to the console and write the command: sudo chmod 777 / home / username_sou /
       NOW CAN TRANSFER REGULAR FILES WITH FILEZILLA

Latest Update!!!
You can just ignore File Manager of step 12 and ignore entirelly step 14 and install wordpress through the command console (download it to /var/www/html with wget command, unzip it with unzip command and final create a database by visit http://IP-OF-YOUR-SERVER-OR-YOUR-DOMAIN/phpmyadmin).
After the installation, go to your wordpress admin dashboard and install File Manager form the Apps menu.
You are ready to go ;)
