First, we need the latest version of the TeamSpeak 3 server for Linux. You can download it here. You can also download the package from the official website.
Move the packages to the server and unzip it.
tar zxvf teamspeak3-server_linux-amd64-18.104.22.168.tar.gz
Now we have TeamSpeak 3 server folder which you want move to the better place. The folder's name depends which package you chose. I assume you work same directory where you download it. You need sudo if you don't work as root or superuser already.
sudo mv teamspeak3-server_linux-amd64 /usr/local/teamspeak3
Run the TeamSpeak 3 server as service
Next we want to make it run as service and startup after boot. First, we make symbolic link to /etc/init.d.
sudo ln -s /usr/local/teamspeak3/ts3server_startscript.sh /etc/init.d/teamspeak3
Then we have to create a user who runs TeamSpeak as a service. We don't want that user able to log in so this is local account only. New user needs privilege to run the service so we must change the ownership of the folder to user teamspeak3.
sudo adduser --disabled-login teamspeak3 sudo chown -R teamspeak3 /usr/local/teamspeak3 sudo update-rc.d teamspeak3 defaults
Running the server first time
Now we’re all done and it’s time to start the TeamSpeak 3 server for the first time.
sudo service teamspeak3 start
Now there is coming very important information for you. You need token to raise your level of admin group and there is also login information for Telnet connections. You can use the token only once, but write down the login information because those are the only way to restore your admin rights if you delete your TeamSpeak information from your client computer.
Your server is probably protected with firewall so you need to open the port for TeamSpeak 3 server. The default port for voice is 9987 (UDP) and for Telnet 10011 (TCP). If you use ufw the command will be:
sudo ufw allow 9987/udp
Gaining the power
Now use your TeamSpeak 3 client to connect your server. When you log in the first time the server will ask the token. Copy the code from the server window and hit enter. Now you're the Boss. You can do whatever you want and no one can stop you.
First, you should go check out server and channel groups and make them as you like. After that, create your channels and let people in.
Restore admin rights
Use Telnet connection to your server where TeamSpeak is running.
telnet your_ip/host 10011
After succiful login write this to input line.
login serveradmin password clientsetserverquerylogin client_login_name=serveradmin
