How can we install Dynatrace Managed while bypassing connection to Mission Control

hmor3 — Thu, 26 Apr 2018 15:10:27 GMT

Hi Guys,

For DT Manage Installation on RHEL 7.4 , I need to bypass the connection to Mission control so that I can complete installation and provide the proxy details later in CMC for connection to Mission control.

Please confirm if it is possible or not to bypass Mission control connection during install

Thanks

Himanshu Mor

You can't bypass the connection to mission control. But why not enter the proxy during installation?

Hello Patrick,

Thanks for confirming that bypass connection to MC is not possible.

I am trying to download via below option as proxy has user/password authentication but it is not working on my RHEL 7 host

wget -O dynatrace-managed.sh -e use_proxy=yes -e http_proxy=http://username:password@proxy_host:proxy_port

Let me know if you can help about wget via user/password authenticated proxy.

However same proxy is working on a windows machine in same subnet.

Regards

Himanshu Mor

I've done this before by setting the proxy in /etc/wgetrc

Thanks Patrick for confirming that process followed by me is correct! I have tried the same by using wgetrc as well as via command line but its not working for me.

Then it appears to be some issue at the proxy side, I am troubleshooting the same with Security team and I will update once resolved.

Thanks for your quick help on this!

I have a similar issue. I was able to install Dynatrace on the primary cluster seed node. But now, when I try to install a new cluster node using a proxy I get "Cannot connect to Cassandra and Elasticsearch ports on seed node". Console output:

Not related to mission control, I would ask this as a new question.

Most likely problem is a firewall blocking traffic between the nodes on the mentioned ports.

Hello @Scott W.

I am going through with the same situation to one of our cluster node. If I get any success then will share with you.

So what was the verdict on this? Was something changed on the proxy end? I am facing a similar issue as well with this at my customer end

Thank you in advance,
