View source for Run your own virtual server


Are you a lazy bum that has no money? Me too! :D<br>
Did you know you can run a virtual OBEY server for about as much money as you find on a sidewalk ?<br><br>

Perfect... here's how!<br>


== Step 1) Register on a service ==
Make an account on [https://www.digitalocean.com/?refcode=76917c2bb42e DigitalOcean.com] '''<-- follow this link to register, you will start with $10 in credit!'''

You will need to register a credit card to start an account (this protects them from anyone running 100 servers 24/7 for no reason).

'''In the billing section you can also put RUBYDROPLET to get $10 in credit''' (this can be done at any time, not just during registration).

== Step 2) Create a new droplet. ==

- Select 2 CPU to make a nice multiplayer server.

- Select a region closest to where you want the best ping to occur

- Select Ubuntu (other distros probably work just fine too, but I haven't tested them)

- click "Create Droplet"

== Step 3) Set up the server ==

- Select your droplet (every droplet is a server).<br>
- Go to Access Tab, and click on Console Access<br>

- When you see the black screen type '''root''' as a username and press enter<br>
- Then '''''check your email''''' to type the password you should have received in the mail.<br>
- Enter it and set a new one as prompted.<br>

'''sudo apt-get install unzip''' <span style="color:#ccc">//install zip/unzip functionality with this</span>

'''adduser userName''' <span style="color:#ccc">//make a new user (not good practice to do everything as root).
it will ask you for details about the user, but you can leave the options blank by pressing <enter>.  Then...</span><br>
'''logout'''  

<span style="color:#ccc">''and then log back in now as the user you just created (as will be good practice from now on)''</span>

'''mkdir OBEY{{Current_Version}}'''  <span style="color:#ccc">//let's make a folder in the new user's home dir to contain the build we want to use</span>

'''cd OBEY{{Current_Version}}''' <span style="color:#ccc">//navigate to the directory</span>

'''wget <nowiki>http://www.obeygame.com/build/OBEY</nowiki>{{Current_Version}}<nowiki>_server.zip</nowiki>'''  <span style="color:#ccc">//download OBEY into it</span> 

'''unzip OBEY{{Current_Version}}_server.zip'''  <span style="color:#ccc">//and unzip it</span>

'''rm OBEY{{Current_Version}}_server.zip'''  <span style="color:#ccc">//(optional) if you want to delete the zip we downloaded, we don't need it anymore</span>

<span style="color:#ccc">''Use nano text editor to configure your server settings...''</span>

'''nano serverSettings.txt'''  <span style="color:#ccc">//use ctrl + o (and press enter) to SAVE and ctrl + x to EXIT</span>

== Step 4) start a server ==
''Then, from the directory where you have unzipped the build...''

'''sh RUN_SERVER.sh'''

== HOW TO RUN SERVERS FOR MERE CENTS!!! ==

Now digitalocean.com charges us 3 cents an hour to run our nice dual-processor server (running it constantly will come to $20 a month).<br>
Every bunny knows that's a LOT of money (thats like 2 dropships!).<br><br>

So to keep costs ultra low we just run the server when we want it.<br>
digitalocean.com will charge us as long as we have a droplet (even if it's shut down), so to save money we delete our droplets when we don't want to be charged anything.<br>  
Now if we do that right now we will lose all our settings, so in order to not have to go through the setup again we create a snapshot.

'''logout'''<br>  
<span style="color:#ccc">''log back in as 'root'''...</span><br> 
'''poweroff'''  <span style="color:#ccc">//shut down the server (droplet)</span>

<center>
Then save a snapshot as shown (name it whatever you want)<br>
...it might take 1 or 2 minutes to save.<br>
[[File:virtualServerHowTo5.jpg]]<br><br>

Then we can delete our droplet to not be charged any cents!<br>

When you want to start the server again start a new droplet, except this time use your snapshot!<br>

</center>

<span style="color:#ccc">''log in''</span><br>
'''cd OBEY{{Current_Version}}'''  <span style="color:#ccc">//Navigate to the location of OBEY</span><br>
'''sh RUN_SERVER.sh''' <span style="color:#ccc">//KILL BUNNIES</span>

You can even run more than one at once now (at 3 cents per hour)

== How to send custom files to your remote server ==
Now that you have your own server running... you might want to send custom maps or server settings to it.
There are various ways of doing it, here are the two easiest in my opinion:

'''With FTP''' 

If you have a web hosting (ie you run a website),  the easiest way is using FTP and using wget to get your files onto the server.


'''Without FTP'''
 
Most people don't have access to a web server, so here is how to do it pretty easily.  

1) First step is to download [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html PuTTy], and use that to log into your droplet. 
<center>To connect, simply '''type the IP of the droplet''' in the prompt and '''press Open'''.
[[File:virtualServerCustomFiles00.jpg]]
Then log in normally, and navigate to the folder where you want the file to go.</center>

2) Go to [http://www.dropcanvas.com Dropcanvas.com] and drag your file into the page.
<center>[[File:virtualServerCustomFiles01.jpg]]</center>


3) '''Right mouse click''' on the file and '''Copy Link Address''' or equivalent on your browser.
<center>[[File:virtualServerCustomFiles02.jpg]]</center>

4) In Putty,  type:<br>
'''wget (rmb to paste the link you copied) -O mapName.tmx''' <span style="color:#ccc">//(the -O is optional, but otherwise your file will have a strange name)</span>





== PRO-TIPS ==

if you make a mistake use  the command '''rm''' to delete stuff. For example:

'''rm fileName'''  will delete fileName (rm = remove)

'''<nowiki>rm -r someDir/*</nowiki>'''  will delete everything inside someDir recursively (be careful!)

'''pwd''' shows you where you are (pwd = present working directory)

'''ls''' shows you the contents of where you are (ls = list)

'''cd someDir''' climbs into someDir (cd = change directory)

'''cd ..''' climbs UP a directory level

'''mv from to''' move command can be used to move or rename files

'''top''' will tell you performance and memory stats on what your server is up to. use Ctrl + C or Q to exit it.

- You can press TAB to auto-complete file and dir names

- You can press the up arrow to repeat the last command

- If you are on Windows, check out [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html PuTTy] to log in, it's better than using the interface on the website, because you can copy/paste and it won't use bandwidth.

- '''NOTE:''' if you get an error that looks like "OBEY.x86 not found" when you try to run the server, it means you are are running a 32bit app on  a 64bit os or visa versa

- You can add the new user to the 'super user' group so he can run admin tasks on the server instead of having to log in as root:

'''gpasswd -a userName sudo'''

- If you want to close the terminal window  but leave the server running, type the following:

'''press cntrl+z''' to escape the server state (which also pauses it)

'''bg'''  will send the server to the background (unpausing it)

'''disown'''  stop attaching it to you

'''exit''' exit the window and the server will run on..  :)

- If you want to kill a running server use '''top''' to lists existing jobs then '''kill #''' to kill the job with the given job id number

== Security ==
If you are planning on running the server for long periods of time without frequently reverting back to a fresh droplet, consider adding port security.  [http://www.howtogeek.com/177621/the-beginners-guide-to-iptables-the-linux-firewall/ Iptables is recommended]. (If anyone can expand this section with a step by step guide for securing the appropriate ports that would be helpful)
