Installing Mumble Server & Client

February 20, 2018

Server Install for CentOS 7

Just copy these commands as root, or use sudo before them.

yum install bzip2
useradd mumble 
su mumble
mkdir ~/tmp && cd ~/tmp wget 
tar -vxjf ./murmur-static_x86-1.2.8.tar.bz2 rm murmur-static_x86-1.2.8.tar.bz2 
cp -r ./murmur-static_x86-1.2.8/* . 
cd /home/mumble 
mkdir logs 
chmod 770 logs 
cp ./murmur-static_x86-1.2.8/murmur.ini /etc/murmur.ini

Edit the Config file vi /etc/murmur.ini

Make sure to edit these values:


Now let's make sure mumble starts up on boot vi /etc/systemd/system/murmur.service Make sure it looks like this

Description=Mumble Server (Murmur) 

ExecStart=/home/mumble/murmur.x86 -ini /etc/murmur.ini 


Start mumble

systemctl daemon-reload 
systemctl start murmur.service

You'll need to define a super user password ./murmur.x86 -supw ROOTPASSWORD

Adding a User Account to the Admin Group

In Mumble the administrator account is known as the SuperUser. It is recommended that the SuperUser account is only used to configure the initial Administrator account on your Mumble server and is left with a secure password.

  • Right click the Root channel at the top and select edit. The Root channel is where your server properties are stored and any channel below this channel will inherit the account policies unless explicitly excluded.
  • Click on the Groups tab at the top. Select the 'admin' group from the Group dropdown box. Select or Type the username you wish to add to the 'Admin' group in the dropdown box below the Members box. Then click the Add button to the right.
  • Click the OK button on the bottom right. If the SuperUser password was incorrect a password box will be displayed when you attempt to connect to the server.

Downloading the Client

Download the "Stable Release" here:

Open up the installer when downloaded and follow the normal steps. On first launch mumble will start up the audio wizard. Make sure the correct audio devices are selected. If using a laptop the default devices are the built in ones, if using a desktop make sure to select the correct ones. Un-tick the positional audio and attenuate other applications boxes. Click next. Device tuning, slide it all the way left, if the recording sounds fine then press next. If you get a jitter, move the slider right till it sounds fine. The next steps tests your microphone, just follow the steps. Quality settings, select high. Click next and finish.
