Once the installation is complete, use the following administrator login and password for managing Flussonic Media Server:
Do change them immediately after the installation, so as not to compromise the security of your server.
In order to change the administrator password, you can edit the config file
and change the value of the
When you are done manually editing the config file, run the following command:
Another way to change the administrator password is using the Web interface (Config > Access):
Supported architectures: amd64, armhf, arm64. The i686 architecture is not supported.
Required OS version: Ubuntu 16.04 and newer, Debian 8 Jessie and newer.
Installing Flussonic Media Server using Debian package:
wget -q -O - http://apt.flussonic.com/binary/gpg.key | apt-key add -; echo "deb http://apt.flussonic.com binary/" > /etc/apt/sources.list.d/flussonic.list; apt-get update; apt-get -y install flussonic flussonic-transcoder;
Note. The package
flussonic-transcoder is necessary only if you plan to use the CPU to perform transcoding.
To learn what packages you can install, use the following command instead of the command above:
apt-get -y --install-recommends --install-suggests install flussonic
Now you are ready to start Flussonic Media Server:
Open in browser Flussonic admin web interface on the page
http://flussonic-ip:8080/ and paste there license key that you have received (change "flussonic-ip" to the real address of the server). On this page you can change administrator login and password.
License key stored in
/etc/flussonic/license.txt file, you can put the key there before start.
You can check whether your Flussonic installation is correct by visiting
http://flussonic-ip:8080/ where flussonic-ip is the address of the hosting server to which you installed the software. You can also run the following command:
Now installation is complete, and Flussonic Media Server is ready to operate. However, for best performance with a high client volume, we suggest you do some system tuning.
You also need to completely disable a swap, as its presence is not compatible with video streaming. If the server doen't have enough RAM, it can't be extended b y a swap.
Important! We strongly recommend that you avoid using RPM-based distributions: Centos, Redhat, Suse etc. This is due to a number of reasons. We do not provide technical support on issues concerning RPM packages and distributions to users who have purchased less than 10 user licenses.
Installing Flussonic Media Server from Yum repository:
cat > /etc/yum.repos.d/Flussonic.repo <<EOF [flussonic] name=Flussonic baseurl=http://apt.flussonic.com/rpm enabled=1 gpgcheck=0 EOF yum -y install flussonic-erlang flussonic flussonic-transcoder # Save the key in /etc/flussonic/license.txt /etc/init.d/flussonic start
By default, in OS Linux the max number of open files per process is set to 1024.
This means that once the number of connections goes slightly over 1000, new connections will be refused even though there is still enough resources.
Add the following lines to
root soft nofile 65536 root hard nofile 65536
The number of open descriptors exceeds the number of client connections.
Important! The syntax in the limits.conf file may vary from OS to OS. This documentation gives a working example of syntax for Debian/Ubuntu. Under other systems, syntax may be different.
To install updates, simply update the packages and install Flussonic:
apt-get update apt-get -y install flussonic /etc/init.d/flussonic restart
dpkg -l | grep flussonic # ii flussonic 3.71.14 amd64 Videostreaming server
It is sometimes necessary to install the previous version.
To do this, you must specify the exact version of the
flussonic package and its dependencies.
Suppose you want to revert to version 19.06.1.
Get dependencies' versions by using
apt-cache show flussonic=19.06.1 | egrep '^(Depends|Suggests):' Depends: flussonic-erlang (=21.3.6) | flussonic-erlang_21.3.6, flussonic-transcoder-base (=4.6.2) | flussonic-transcoder-base_4.6.2 Suggests: flussonic-transcoder (>= 4.5)
Install packages with these versions:
apt-get install flussonic=19.06.1 flussonic-erlang=21.3.6 flussonic-transcoder-base=4.6.2
Before installing packages create a backup of the configuration files in the directory
.db files in the directory
(this directory is used by default, you can change the path in the configuration file).
Important! We cannot guarantee the server's operation on those Linux distributions for which we do not provide installation packages.
Use the following commands:
to start the service:
to stop the service:
to restart the service:
to reconfigure with client connections live:
Please see the minimum system requirements to the host server for running Flussonic Media Server in the table below. In reality, the requirements may slightly vary depending on the number of concurrent connections to Flussonic server.
Important! When calculating host server capabilities, all resources required for normal functioning of the operating system and other services running parallel to Flussonic must be taken into account.
Minimum system requirements
|Concurrent connections||10||100||1 000||5 000+|
|Processor||Any||Single core||Quad core (Xeon / Core i7)||Dual core Xeon E5|
|RAM||128 MB||256 MB||1024 MB||16 GB|
|Free disk space||40 MB||40 MB||40 MB||40 MB|
|Network adapter||100 Mbit/s||1 Gbit/s||1 Gbit/s Server NIC||10 Gbit/s Intel|
|Operating system||Debian Linux, Ubuntu Linux|
For stable streaming video playback with a high volume of concurrent connections, we recommend distributing the traffic load among several real servers. For detailed information on clustering of Flussonic servers, please see the Clustering section.
Please note that when files on disk are used as the data source, the disk subsystem bears the main burden. Consequently, when planning the host server architecture for running Flussonic Media Server, special attention should be paid to the hard disk performance. For more detail on this subject, please see file streaming.
If the host server is protected with a firewall, exception rules must be set for ports and protocols used by Flussonic Media Server.
For the commercial version, it is also vital that Flussonic Media Server itself has access to the Internet via HTTP and HTTPS protocols.
