I have a Wowza 4.0.1 AMI and I’m trying to update to Wowza 4.0.3. I’ve tried using the linux installers here [https://www.wowza.com/pricing/installer](https://www.wowza.com/pricing/installer).

Hi Steven, Do you have root access when running the installer? Also, on what OS are you attempting the install? We do offer pre-built AMI’s for EC2, which are very useful: [**Pre Built AMI’s**](https://www.wowza.com/docs/pre-built-amis-amazon-machine-images) -Tim ---

Steven, You can do it in SSH client like this: sudo su - cd /home/wowza/updates mkdir WowzaStreamingEngine-Update-4.0.3 cd WowzaStreamingEngine-Update-4.0.3 wget [https://www.wowza.com/downloads/WowzaStreamingEngine-4-0-3/WowzaStreamingEngine-Update-4.0.3.zip](https://www.wowza.com/downloads/WowzaStreamingEngine-4-0-3/WowzaStreamingEngine-Update-4.0.3.zip) unzip WowzaStreamingEngine-Update-4.0.3.zip service WowzaStreamingEngine stop service WowzaStreamingEngineManager stop cd linux chmod +x update.sh ./update.sh service WowzaStreamingEngine start service WowzaStreamingEngineManager start And you can apply dev patches similarly.

Sounds like running the installer on the pre-built AMI messed this one up. I assume you just started it, I would just start another one. The [current AMIs](https://www.wowza.com/docs/pre-built-amis-amazon-machine-images%28amazon-machine-images%29) are 4.03.01. Richard ---

Hi Tim, Thank you for your response. I do have root access. I’m actually using the WowzaStreamingEngine-s3-lickey-4.0.1-x86\_64 AMI. Is there an easy way to update the image or should I be using the installer? Thanks, Steven ---

Thanks Richard, I tried: service WowzaStreamingEngine stop And I got this back: WowzaStreamingEngine: unrecognized service So I ran “service --status-all” and I didn’t see anything related to wowza. > acpid is stopped > > atd (pid 1472) is running… > > auditd (pid 5522) is running… > > cfn-hup is stopped > > Checking for service cloud-init:Checking for service cloud-init:Checking for service cloud-init:Checking for service cloud-init:crond (pid 5484) is running… > > ip6tables: Firewall is not running. > > iptables: Firewall is not running. > > irqbalance is stopped > > Checking jexec statuslvmetad is stopped > > mdmonitor is stopped > > messagebus (pid 1195) is running… > > netconsole module not loaded > > Configured devices: > > lo eth0 > > Currently active devices: > > lo eth0 > > ntpd (pid 1308) is running… > > Process accounting is disabled. > > racoon is stopped > > rdisc is stopped > > rsyslogd (pid 5547) is running… > > saslauthd is stopped > > sendmail (pid 1333) is running… > > sm-client (pid 1340) is running… > > openssh-daemon (pid 5444) is running… > > svnserve is stopped > > vsftpd (pid 1318) is running… I stopped the server and manager by running “/usr/local/WowzaStreamingEngine/bin/shutdown.sh” and “/usr/local/WowzaStreamingEngine/manager/bin/shutdownmgr.sh”. It looked like that worked. The stream is no longer running and the server manager is down. But when I try running ./update.sh I get this response: “Wowza Streaming Engine appears to be running. Please stop it before continuing.” ---

Thanks. I’ll do that.
