Re: Internal Server Error when trying to access /iredadmin

Please install package "python-psycopg2" with yum, then restart "iredadmin" service.

Package python-psycopg2-2.7.5-1.rhel7.1.x86_64 is obsoleted by python2-psycopg2-2.8.3-3.rhel7.x86_64 which is already installed
Nothing to do

Re: Internal Server Error when trying to access /iredadmin

Does restarting "iredadmin" service fix the issue?

Re: Internal Server Error when trying to access /iredadmin

Run “python2” command first, then run commands below in python shell and show me full output:

import psycopg2

Doesn't seem to have worked:

>>> import psycopg2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.7/site-packages/psycopg2/__init__.py", line 50, in <module>

ImportError: /usr/lib64/python2.7/site-packages/psycopg2/_psycopg.so: undefined symbol: PQconninfo

P.S. I have tried 

yum -y remove python-psycopg2 && yum -y install python-psycopg2

Re: Internal Server Error when trying to access /iredadmin

- did you upgrade this server from CentOS 6 to 7?
- try to remove “python2-psycopg2” first, then reinstall it.

This server was built on CentOS7 never 6.

The previous command I listed runs the first command (remove) THEN the second command (install), it just takes away the unnecessary time spent re-typing the command but to install again.

the package name is python2-psycopg2, not python-psycopg2.

ran "yum -y remove python2-psycopg2 && yum -y install python2-psycopg2 && sudo service iredadmin restart"

/iredadmin still comes up with internal server error.

/var/log/messages still shows:

Re: Internal Server Error when trying to access /iredadmin

yum install PyGreSQL && sudo service iredadmin restart
