[ Edited ]

Hi Community,


I ran the wizard but was not able to start the db.


In the log i see : Failed to get D-Bus connection: Operation not permitted


tand able to replicate the issue by:


[root@localhost ~]# systemctl start cloudera-scm-server-db
Failed to get D-Bus connection: Operation not permitted


My Centos is : 

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

Hi Fawze,


I assume when you say wizard, you are running the cloudera-manager-installer.bin .  


You cannot use any other DB with the cloudera-manager-installer.bin, but here are directions on how to manually install  Cloudera Manager with an external database that you need to setup yourself.


I don't know what the failed message means, I have run the cloudera-manager-installer.bin on CentOS 7.3   4 and 5 without that issue.


Good luck,

Hi Tina,

Yes i meant uisng the installer.

I meant if i can use the installer and configure it to use external mtsql.

I will appreciate if anyone who can advise in the mentioed error which is related to the Centos

No, you can't change the installer to setup a different database, sorry.

Thanks Ana,

Now i can got the idea, that i can use the installer for quick installion for POC or use the requlat instrcution of installing cloudera manager and CDH cluster.

I think worth to mention this in the register page for the beta CDH6 since once i register i got a link that includes only the installer.
