FAQ
Hi,

I am trying to install Cloudera manager in RHEL 5.
I have configured and installed MySQL Server version: 5.6.10 MySQL
Community Server (GPL), following instructions from
https://ccp.cloudera.com/display/ENT4DOC/Installing+and+Configuring+a+MySQL+Database.

When I started the Cloudera manager , I am not able to browse the
UI,moreover facing this exception
Can somebody help on this issue, as I have stuck on this issue for quite
some time.
Thanks in advance.

    Hi Ravi,

    It seems like CM is having issue when connecting to the MySQL db. What is
    the content of /etc/cloudera-scm-server/db.properties? Can you use the same
    credential and successfully connect to mysql db using 'msql' client (mysql
    -h <host> -u <user> -p <dbname>)?

    Can you also check:
    1. Ownership of the /etc/cloudera-scm-server/db.properties file (ls -l
    /etc/cloudera-scm-server/db.properties).
    2. The state of CM service (service cloudera-scm-server status).

    Cheers,
    Vikas
