Did you read and complete Step 0?

 

https://www.cloudera.com/documentation/enterprise/5-11-x/topics/cm_sg_tls_browser.html#xd_583c10bfdb...

 

This will have you create or obtain a server certificate and put it in a Java keystore.  If yes, is it located in the path listed in the exception, /var/lib/cloudera-scm-server/.keystore?  If yes, is it owned by the user that is trying to launch the cloudera-scm-server process, should be cloudera-scm?

thanks for your response. i perform level 0 using selfsigned certificate 

https://www.cloudera.com/documentation/enterprise/5-11-x/topics/sg_self_signed_tls.html#sg_self_sign...

my keystore is in /opt/cloudera/security/jks.

can i simply move it on /var/lib/cloudera-scm-server/.keystore?

Yes. Move it and ensure that the user running the cloudera-scm-server has read access to it.

I do not beyond the Cloudera docs. I have not seen the second error. The Google translation I got was FileNotFoundException (is a record).

To validate that the keystore is good can you run the below command.

keytool -v -list -keystore /var/lib/cloudera-scm-server/.keystore

when i enter the command:

Type Keystore : JKS
Fournisseur Keystore : SUN

Votre Keystore contient 1 entrée(s)

Nom d'alias : cmhost
Date de création : 17 juil. 2017
Type d'entrée : PrivateKeyEntry
Longueur de chaîne du certificat : 1

after i have restarted the service i have this error:

is there a way to cancel all the configuration i have done in cloudera manager? i want to restart the configuration since level 0

Aww I can work with password must not be null.  I assume that the keytool command did not prompt you for a password.  This means that the Java keystore and possible the private key are not password protected.  Most service require that a password be set.  The challenge here is whether you specified a password in the Cloudera Manager configs.  If yes, and you recall it, you can recreate the key and cert in the JKS with that password and bring CM up.

 

Note: the key and JKS password must be the same, CM assumes they are.

 

To revert, you will need to log into the CM database and manually modify it.  Let me track down those instructions.
