[ome-users] Ansible playbook for installing OMERO 5.1 on CentOS 7

[Kenneth Gillen (Staff)]

Hi Tjelvar,

That's really awesome! Thanks for sharing it with the community!

With regard to problem 1: the system's hostname is not in `/etc/hosts`.

Add `vagrant-centos7` to the end of each of the entries, e.g.

[root at vagrant-centos7 OMERO.server]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 vagrant-centos7
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 vagrant-centos7

I'm afraid I can't help directly with your second error message, though fixing the first might well alleviate the second. Perhaps someone else on the list would be able to confirm that.

All the best,

Kenny

Subject: [ome-users] Ansible playbook for installing OMERO 5.1 on CentOS 7

Dear all,

I have created an Ansible script for installing OMERO 5.1 on a CentOS 7 machine.

You can access it from GitHub:

https://github.com/JIC-CSB/omero-ansible

The repository includes a Vagrant file for creating a CentOS 7 virtual machine,
which can be used for testing the Ansible playbook.

There are some outstanding issues in that errors are reported in the logs.

I’m not too worried about the DropBox errors as it has not been configured.

The Blitz, Index and PixelData errors seem to have something to do with the hostname.

Whereas the Processor and Tables errors seems to be in the Python layer.

Any suggestions on how I can make these errors disappear would be gratefully received.

Kind regards,

Tjelvar
