CentOS 7 Setup Guide for VPS via DigitalOcean


CentOS 7 Setup Guide for VPS with DigitalOcean

This will be a setup guide from Starting with DigitalOcean to Phantombot running fully.
I’ve double check if they still have that promo for new users on their main site but it’s been removed. Usually you can get $100 for 60 days that will give you enough time to play around with the droplets.
The cool part with DigitalOcean is if you done something wrong or something happened you can always delete the server and make a new one, it’s that easy!

DigitalOcean: https://www.digitalocean.com/

Step 1: Creating a droplet

Top right you will see a green button named “Create” click on it.

Click on Droplets “Create cloud Servers”

Choose the OS named CentOS 7.6 x64

Choose a plan, keep this on standard. And choose the $5 a month.
Next option is purely up to you if you wish that DigitalOcean makes backups of your VPS every week.
Next what you need to choose is the server location, I’d suggest to choose the one closest to you.

Additional option would be monitoring.
At host name you can leave it or change it to what you prefer.

And final click the create button on the bottom!

Now you are done creating your VPS CentOS server.

Step 2. Acquiring the tools

Tools we need in order to continue:

Step 3. Setting up the CentOS server

Check your email you should have received an email from DigitalOcean with IP and login details.
Open your putty app and fill in your ip that you have received and give it a name so that you can save the address for later use if needed.
Once you connected to the server via ssh you will be greeted with a message saying do you wish to accept this connection, click yes.
Your default username is root ( admin) and temporary password is the one given to you via email.
Copy your password and go back to putty. Type in root and hit enter, after you can enter your password by right clicking on your mouse this will paste the password you copied. (this counts for any text you copied) The temporary password you received needs to be changed, retype in the old password and change it to something you prefer having.

Step 3.1 Updating your CentOS server.

Type in

yum update

After it collected all the files type y for yes to download. The system prompt you with the question to install this. Type in y for yes to continue. Wait for it to finish.

Step 3.2 Installing the necessary programs

3.2.1 Installing the firewall

Type in

sudo yum install firewalld

To start the firewall service type in:

sudo systemctl start firewalld

We also need to enable the firewall services by typing in:

sudo systemctl enable firewalld

You can check if the service is running by typing in:

sudo systemctl status firewalld

Now you can add the rule to open the ports for phantombot by typing:

sudo firewall-cmd --zone=public --add-port=25000-25004/tcp –permanent

Now we need to reload the changes by typing:

sudo firewall-cmd –reload

3.2.2 Installing the Text Editor

Now we need to install Nano software. (Text editor)
To install it type in the following:

yum install nano

and then type in y and enter to install it.
And you are done with installing Nano.

3.2.3 Installing java.

Type in

yum install java-1.8.0-openjdk-headless.x86_64 wget unzip bzip2

(Optional) You can check your java version by typing:

java -version

3.2.4 Installing Fail2Ban.

This service helps to stop people/bots from trying to connect to your server. (just a precaution)
We need to start with installing a required package named Extra Packages for Enterprise Linux EPEL for short.
Type in:

sudo yum install epel-release

Now we can install Fail2Ban

sudo yum install fail2ban

Once the installation has finished, we can enable the service.

sudo systemctl enable fail2ban

Now we can create the simple config for fail2ban
Type in:

sudo nano /etc/fail2ban/jail.local

Press INSERT button so that you can paste the following (Remember you can right click with your mouse to paste in SSH):

# Ban hosts permanently :
bantime = -1
# Change to your IP address. You can add more by adding a comma. 
ignoreip =,
Override /etc/fail2ban/jail.d/00-firewalld.conf:
banaction = iptables-multiport

enabled = true

After you paste the config you can press ctrl+x to exit, press y to save, and then press Enter to confirm the filename.
Now we can restart the service:

sudo systemctl restart fail2ban

You can check the logs if needed via WinSCP, login as root and go to directory

-> root
  -> var
    -> log

Step 4 Installing & Setting up Phantom bot.

Source: CentOS 7 Setup Guide by Zackery. I’ve adjusted his source with more details.

4.1 Creating a user for phantombot.

NEVER run this type of applications as root or root-user! Provide only necessary privileges to keep your server secure!

To create a new user and the corresponding home directory you have to type the following:

useradd botuser

passwd botuser

Now you can type in a password you wish to have. Please keep in mind to have a secure password. And nothing simple and easy.
Now we have created the user and the home directory for him.

4.2 Installing Phantombot.

First, add the bot to the wheel group

usermod -G wheel botuser

Then switch to your botuser:

su botuser

Switch to the home directory:

cd /home/botuser

Now we need to download the latest PhantomBot release.
Replace the x.x.x with the latest stable version of phantombot. (In this case it’s 3.0.0)

wget https://github.com/PhantomBot/PhantomBot/releases/download/vX.X.X/PhantomBot-X.X.X.zip

After the download has finished, we have to unzip the files.

unzip PhantomBot-X.X.X.zip

To make future updates a bit easier, we have to rename the PhantomBot folder.

mv PhantomBot-X.X.X phantombot

The last thing we need to do is to assign the right privileges to make the launch.sh and launch-service.sh files executable.

cd phantombot

chmod u+x launch-service.sh launch.sh

sudo chown -R botuser:botuser *

Now we are ready to launch PhantomBot. You can run the bot with:


Now PhantomBot should start and you can begin to use it. At this point you can enter the information it asks you for. As a reference, you can check the Windows guide for the bot account configuration.

After the bot is configured you can press the following keys and follow the rest of the guide.

Ctrl + C

4.3 Setting up a systemd Unit

We need to switch back to root user.

su root

Enter password for root and continue.

We need to create a new file called phantombot.service.

vi /etc/systemd/system/phantombot.service

Press INSERT button to paste the following into the file:

After=network.target remote-fs.target nss-lookup.target



Then press ESC to stop adding anything else.

Now we can press shift + ; and type in:


And hit ENTER now you have saved the service.

After this, we have to reload the systemctl and enable the created file to run at boot as a service.

systemctl daemon-reload

systemctl enable phantombot

Now one last thing we need to do, is to make the commands work to start|stop|restart|status PhantomBot.
We have to open the sudoers file to grant our botuser the rights to run these commands.


Press INSERT so that you can edit the file.

On the end of the file add this (just press arrow down till the end):

botuser ALL=NOPASSWD: /bin/systemctl start phantombot, /bin/systemctl stop phantombot, /bin/systemctl restart phantombot, /bin/systemctl status phantombot

Then press ESC to stop adding anything else.

Now we can press shift + ; and type in:


And hit ENTER now you have saved the file you edited.

Now the user “botuser” should have the rights to run the specific commands to start|stop|restart|status PhantomBot.
Let’s try it!

Switch to our botuser:

su botuser

Once you switched to botuser you can run the following commands.

To start the bot:

sudo systemctl start phantombot

To stop the bot:

sudo systemctl stop phantombot

To restart the bot:

sudo systemctl restart phantombot

To check if the bot is running or not.

sudo systemctl status phantombot

If you have set up all correct it will start|stop|restart|status PhantomBot.

After PhantomBot is started, you can find your Control Panel under “YOUR-SERVER-IP:25000/panel”.
Make sure you open the following ports on your server: 25000-25004 See " 3.2.1 Installing the firewall" .

4.4 Setting up the Backup for every 24 hours.

Switch to botuser

su botuser

Go to the directory of the user.

cd /home/botuser

Now you can make a backup folder.

mkdir -p backup/phantombot

To edit the the schedule for the crontab type in the following:

crontab -e

And now you can add the following:

1 4 * * * umask 0007;/bin/tar --exclude=/home/botuser/phantombot/lib --exclude=/home/botuser/phantombot/web -cjf /home/botuser/backup/phantombot/$(/bin/date +%Y-%m-%d-%H_%M_%S_%3N).tar.bz2 /home/botuser/phantombot/ >>/home/botuser/backup/backup_phantombot.log 2>&1

Use this to check your crontab afterwards:

crontab -l

Thats it for to setup the bot via a VPS

5 Optionals

5.1 Mobile App for the iPhone.

I personally use PiHelper app on the App Store for the iPhone. It’s free and you can add simple commands to it. This app is build for Raspberry PI and any linux based system.

Add your bot info so you can login. You can also test the connection to see if you properly added the information.

Once you have added the server it will look like this.

Now you can tap on the server to get to the more detailed section and on the top right there’s a drop down menu.

Now you can add your custom commands like start, restart, stop, status.

Hit save and now you can go back and tap the dropdown menu.

And you are done! Now you can press any command and it will let you know if its started, restarted, stopped or ran the status command.

I dont own an Android. But if you guys know any decent app or similar to this one let me know and I’ll add it to the list.

5.2 Hide your server IP

To hide your ip for free use https://www.noip.com/ , register an account with them and choose your free domain so you can add the server ip to it. It can take some time for the domain to register the IP but mostly happens within 15min.

Hope this helps anyone interested in creating their own VPS server for phantombot. If there’s anything that needs to be added let me know.
