Cloudera 5.0.1 Installation is failing

Cloudera 5.0.1 Installation is failing

New Contributor
I am trying to install Cloudera manager but it is failing and below is the log file:
I have uninstalled postgres and tried again but still the same error.

It would help if you provided us with more information.

 

Example what user are you using and if you've setup rights per user to run as appropriate user, etc. Version, OS, etc

I am getting the exact same error when installling Cloudera manager 5.4 on Centos 6.6.   I am running the installer as root, so not sure why there is a permission denied message and postgres is unable to initialize.  Any help is appreciated.

Verify you have disabled SElinux as well as iptables for the installation of any release.  Stick to following the documentation on installation, the requirements are detailed here:

 

http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_ig_cm_requirements.h...

 

The document covers the networking and security requirements in the last section, but we sugges reviewing the full discussion from that page.

SELinux and iptables both are disabled.  I have tried to follow each and every step.  However, I still get the same error.

I had similar error and found out cloudera was using a hostname ssh-key that I never setup because of nsswitch defaults were reversed.

 

If you have a multi-node cluster make sure you run :

 

# ssh-copy-id node1 thru node 200 <-- Resolved my issue

 

# ssh-copy-id node1

 

This was also causing database connection issue. The user did not have the  ssh id.

 

Hope this helps

I do not have a cluster of node.  This is the first time I am setting up cloudera manager on a single node.  Not sure if I still need to use ssh-copy-id.  Help much appreciated.

I never had that issue but I did issue this on all nodes to every other node.

 

# ssh-keygen

 

When generating keys, enter through no entry needed for generating keys {enter, enter, enter, enter}

 

# ssh-copy-id localhost   <-- have username and password used for cloudera that you setup

# ssh-copy-id 127.0.0.1   <-- have username and password used for cloudera that you setup

# ssh-copy-id {anyEx-IP-Address-you-have-configured}           <-- have username and password used for cloudera that you setup

 

I don't know how you're setup but this is worth a try.

 

I use this on Apache Hadoop as well and works perfectly.

Thanks for your help, but bad news.  Now ssh is enabled for local host and 127.0.0.1 with the password that I setup when generating rsa keys, but still the cloudera manager installer fails and gives the exact same error.  I am running out of ideas now.....  And this is single node....

Can you show complete error?
