In case you want to use the auto updater for this, just follow these steps:

Auto updater

Open a SSH session to your Wowza server and navigate to your /tmp directory and download the update installer and run it with sudo

cd /tmp
wget https://raw.githubusercontent.com/nlmaca/Wowza_Installers/master/Ubuntu/03_UpgradeStreamingEngine.sh
sudo bash 03_UpgradeStreamingEngine.sh

Manual installation

In case you want to manually update your wowza server you need to have a wowza account so you can download the latest (zip) update. 

Step 1 – Preparation

Login to your wowza account and download the update version to your computer. There is no downloadlink available outside your wowza account.

After the download you have to upload the file to your server to the /tmp directory. 

Step 2 – Install unzip

sudo apt install unzip -y

Now navigate to your /tmp directory. We have to unpack the zip file and move or copy it to the Wowza update folder. 

cd /tmp
sudo unzip WowzaStreamingEngine-Update-4.8.23+2.zip -d /usr/local/WowzaStreamingEngine/updates/WowzaStreamingEngine-Update-4.8.23+2

Step 4 – stop wowza services

Before we start the update make sure you have stopped the wowza services

sudo service WowzaStreamingEngine stop
sudo service WowzaStreamingEngineManager stop
