Installing Murmur on CentOS

Recently I had the chance to set up a Mumble server (aka “Murmur”) on CentOS 6. I use MySQL as the database and “MyMumb Panel” as the management interface (see GitHub: MyMumb-Panel).

The installation itself was very easy, but things started to get stuck when setting up the init.d script, so my documentation is (still) a bit thin. More to follow.

Preparation

When starting the service, Murmur uses the “lsb” command, which isn’t available on CentOS by default. To avoid an annoying error message and a process marked as “defunct”, we install the “redhat-lsb-core” package:

yum install redhat-lsb-core

Installation & Configuration

Since I didn’t feel like compiling Murmur myself for now, I fell back on the “stable” binaries (see SourceForge: Mumble).

• Unpack & create directories
• Create a MySQL database (or use the bundled .sqlite database)
• Open the ports in IPtables with iptables -A INPUT -p udp -dport 64738 -j ACCEPT iptables -A INPUT -p tcp -dport 64738 -j ACCEPT
• Adjust Murmur.ini, i.e. enter the credentials for the MySQL database, disable dBus, adjust the paths for log and PID files, etc.
• Create an init.d startup script. (Example below)

BONUS: Setting up the MyMumb management interface with ZeroC Ice

(At this point I had to compile ZeroC Ice, because no suitable binaries were available - instructions to follow…)

Generate the matching PHP file for MyMumb from the Murmur Ice “slice”:

/opt/Ice-3.5.1/bin/slice2php -I/opt/Ice-3.5.1/slice Murmur.ice

…and place it in the MyMumb directory

mv Murmur.php /srv/www/mumble/htdocs/inc/

Example CentOS init.d startup script
