CentOS 7 Setup Guide


#1

You need a user which has root privileges on the server to get this working! If you don't have root privileges, you may encounter unsolvable problems during setup. But it's possible to get the bot running without them.

1. Get your system ready

First thing is to make sure, that your system is up to date. Before we install anything, we check if this is the case.

Type into the terminal or your SSH client:

yum update

2. Setting up Java JDK and other requirements

PhantomBot requires Java to run on your machine. In this case, we will use the OpenJDK runtime which can be installed via yum.

To install the OpenJDK-Runtime and the other requirements we need to type the following into our terminal:

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

This will install all the necessary files we need to get PhantomBot running.

Now you can check your Java version with this command:

java -version

The output should be similar to this:

openjdk version "8-internal"
OpenJDK Runtime Environment (build 8-internal+0-2016-04-14-195246.buildd.src)
OpenJDK 64-Bit Server VM (build 8-internal+0-2016-04-14-195246.buildd.src, mixed mode)

Now we have Java installed and can get further to install PhantomBot.

3. Create a PhantomBot user

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

Please take a good password! Nothing like 123 or similar are really secure!
Now we have created the user and the home directory for him.

4. Installing PhantomBot

Now we’re ready to install PhantomBot into our botuser directory.
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:

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

Replace the X with the current release version like PhantomBot-2.3.5.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:

./launch.sh

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

5. Setting up a systemd Unit

Create a new file called phantombot.service as root.

vi /etc/systemd/system/phantombot.service

Paste this into the file:

[Unit]
Description=PhantomBot
After=network.target remote-fs.target nss-lookup.target

[Service]
User=botuser
Group=botuser
Restart=on-failure
RestartSec=30
ExecStart=/home/botuser/phantombot/launch-service.sh
KillSignal=SIGTERM

[Install]
WantedBy=multi-user.target

After this, we have to install 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.

visudo

On the end of the file add this:

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

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

Then as “botuser” try:

sudo systemctl start phantombot
sudo systemctl stop phantombot
sudo systemctl restart phantombot
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.

6. Opening the Panel Ports

First you’ll want to enable your firewall. Centos 7 can have it disabled by default, even when disabled the ports won’t be opened.

sudo systemctl enable firewalld

Then you’ll want to start the firewall.

sudo systemctl start firewalld

After that you can open the ports.

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

Reload the firewall after to apply your changes.

sudo firewall-cmd --reload

Extra - Backup every 24 hours

su - botuser
cd /home/botuser
mkdir -p backup/phantombot
crontab -e

add

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
