RedHat/CentOS installation

Postby nicholas_yue » Fri Mar 22, 2019 7:28 pm


I am new to OMERO server+web installation.

Following the instructions for Ubuntu, I successfully installed both the web+server on Ubuntu 18.04

However, following the instructions for CentOS, I was not able to install it for either CentOS 7.x nor RedHat 7.x

Is there some common mistakes newbie makes when installing on CentOS/RedHat systems ?

From the logs, there seems to be some nginx issue and that it could not get the pid of certain process.

Anyone encountered similar challenges in the past ?

The production machine allocated for OMERO is a RedHat box so I have to work within that constraint.

Are these the instructions you're following? https://docs.openmicroscopy.org/omero/5 ... ce3.6.html

Typical issues include permissions on the OMERO.web and parent directories which prevent access, and SElinux problems which should be detailed in /var/log/audit/audit.log. Installing and running the RHEL/CentOS7 audit2why and audit2allow command line tools will help you analyse /var/log/audit/audit.log.

If this doesn't provide you with enough information to solve the problem please let us know:

- your OMERO server and web configurations
- relevant messages in your OMERO server and web logs
- relevant messages from your Nginx access and error logs
- output of "omero admin diagnostics" for OMERO.server and "omero web diagnostics" for OMERO.web

Thank you. It is a SELlinux related problem. It has since been resolved.
