cfe-lab/Kive: Python 3

The main change is #721 updating to Python 3. Other changes include: #785, #786, and #782 improve error handling when launching Slurm jobs. #774 and #793 fix permissions bugs. #833 removes PostgreSQL 9 left by the previous release. See the milestone for a complete list. Config Changes Install Python 3.6 and switch Apache to launch it. sudo systemctl stop httpd sudo yum install centos-release-scl sudo yum install python36 python36-devel rh-python36-mod_wsgi sudo cp /opt/rh/httpd24/root/usr/lib64/httpd/modules/mod_rh-python36-wsgi.so /lib64/httpd/modules sudo cp /opt/rh/httpd24/root/etc/httpd/conf.modules.d/10-rh-python36-wsgi.conf /etc/httpd/conf.modules.d sudo mv /opt/venv_kive /opt/py27_venv_kive sudo python3.6 -m venv /opt/venv_kive sudo /opt/venv_kive/bin/python -m pip install --upgrade pip sudo /opt/venv_kive/bin/python -m pip install -r requirements.txt sudo sed -ie 's/python2.7/python3.6/' /etc/httpd/conf.d/001-kive.conf sudo systemctl start httpd Add KIVE_SLURM_PATH entry to /etc/sysconfig/httpd. Remove Python 2's .pyc files with find . -name '*.pyc' -delete. Remove PostgreSQL 9 with sudo yum remove postgresql-libs. That will take the other packages that depend on it. The Python packages in Kive's virtual environment should already be up to date, because you just installed them. That should include the switch to psycopg2-binary
