The chosen operating system for the Wowza Server is Debian 8 64-bit, Codename Jessie. The reason this was chosen was because Linux, overall, is a more stable webserver environment. It is also free compared to RedHat and Windows IIS. Due to it's open-sourced nature, support is only as good as your troubleshooting and Googling.
If all is lost, and you need to start from scratch, visit Setting Up Wowza for the First Time.
There is a web-based management panel installed on the Wowza server. It is a free, open-sourced control panel and is a bit limited. It's purpose it to help aid in managing certain settings from a comfortable GUI. The other purpose it to graphically see the status of all important hardware components.
To access this panel, from the school's network only, go to http://wowza.ssdcougars.tv and click "AJENTI PANEL"
The streaming software we use is called Wowza Streaming Engine. The control panel backend is called Wowza Streaming Engine Manager. Users use the WSE Manager to administer common Wowza settings. Below we will go over the basics of starting, stopping the Wowza Service, Upgrading, and troubleshooting streams.
The primary OS and all of it's contents are backed up to
The system uses
rsnapshot and a
cron job to execute it every night.
This backs up the critical files, to a partition on the backup drive. The other partition is the off-line backup for the VPS server.
If the system needs to be rebuilt, use
setv as the main user, rebuild from scratch, then copy back the
Notes to Consider
Shell access (SSH) has been highly secured. All access attempts to port 22 are blocked except from whitelisted IPs.
All IP's under
10.130.0.0/16 are whitelisted, meaning any computer on the SSD Network should have access to the SSH port.
To modify the Whitelist, use the monitor connected to the machine (or use PuTTY with X11 forwarding and Xming) launch
firestarter and click the Policy tab
You can add or remove rules within Firestarter - Leave Ajenti, FTP, HTTP, HTTPS, 8088 and 1935 ALONE! Do not touch these.
All SSH access is authenticated by Certificate. If you lost the cert, you will have to learn how to make a new one for SSH, convert it to a .ppk for PuTTY.
Certs are located on the Archive drives.
Black screen on reboot, videos don't play, cannot sign in via Monitor (CAN sign in via SSH/PuTTY)
Check your disk space, chances are during a reboot it did not mount the backup drive for VOD2, which is networked. If a network mount is not ready in time for the backup rsnapshot job, then it will default create the folder under
/media/vod2bak regardless of successful mount. Thus filling the primary OS drive with VOD2 backup data.
To remedy this:
- SSH into Wowza or Console in at machine (CTRL+ALT+F6)
- Sign in as Root
- Issue command
df -hand determine the size of
/% available is 0, you know the drive is full.)
- Issue command
- Issue command, again
df -hENSURE THAT YOU DO NOT see
10.130.12.192:/mnt/WowzaVOD2BAK/VOD2BAKON THAT LIST, IF YOU DO GO BACK TO STEP 4 -- OTHERWISE, IF YOU IGNORE THIS AND ISSUE THE NEXT COMMAND WHILE
10.130.12.192:/mnt/WowzaVOD2BAK/VOD2BAKIS CONNECTED YOU WILL DELETE THE ENTIRE ARCHIVE!
- Issue command:
cd /media && rm -rf vod2bak
- To confirm this worked, issue
df -hagain and confirm that
/does not =0%
shutdown -r now
