install cluster node

[khaled]

get the message "unable to establish SSL connection" However have --no-check-certificate parameter in the installation command also connected with mission control and DNS properly but pinging on the IP address of mission control is closed, cause of this SSL connection I couldn't continue to install the packages of dynatrace

@khaled are you able to curl to mission control. Using proxy between node to mission control.

curl -v https://mcsvc.dynatrace.com:443 

[khaled]

yes i can curl to mission control, also there are proxy between node to mission control 

[radek_jasinski]

The logs only show the certificate errors?

[khaled]

how to check the logs of the certificate errors?

[khaled]

update : i have downloaded the dynatrace-managed.sh file manually and run it but get failed to connect to mission control and get suggestion in command to change network proxy settings and try again , but when check the connection between cluster and mission control is connected on port 443

[radek_jasinski]

@khaled I understand that once the proxy is set up, everything works?

[RazTN7 · Accepted solution]

@khaled Would it be possible to share curl output here (mask ip and other confidential details)

curl -v https://mcsvc.dynatrace.com:443 

Check error log here -- Installation directory -> Server.*.*.log

Add an SSL certificate to Dynatrace Managed cluster TrustStore

1. Get the .pem version of the certificate assigned to Proxy.

openssl x509 -inform der -in certificate.cer -out certificate.pem

2. Run the reconfigure.sh command.

nohup <PRODUCT_PATH>/installer/reconfigure.sh --update-cert --network-proxy-cert-file <cert_file>.pem &

@RazTN7 This is the following result of curl -v https://mcsvc.dynatrace.com:443
