fails on CentOS 7 and 8

[astlaurent]

Tried installing this on CentOS 7 or 8 as that is our standard linux OS. Not a huge deal, I can run it on ubuntu for a while till things shake out, just wanted you to know i ran into some issues.

If fails a number of items along the way. First it fails building uvloop and it requires the python devel tools. yum install python36-devel. That moved past that problem. The next problem i ran into is the service refuses to install.

The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:

1. A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2. A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3. A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).

Then if i just attempt to start it using the config files from my ubuntu test it throws errors.

Hi,

Yeah, I haven’t had a chance to test v1 on CentOS yet. I know it works as one of the folks in the Gitter group was able to get through the issues, I do remember python3-devel being one of them.

I’ll get the install script fixed for CentOS/RHEL as soon as I can.

Thanks,
Matt

Hi

I was able to work through the issues on centos 7. Here is some stuff i had to do to help you with the docs

I followed your manual centos instructions. I had to do the following items as well before installing hyperglass
activate python 3.6 with scl enable rh-python36 bash. without this python will stay on version 2.x
install python3-devel

then install hyperglass via pip command

then enable and run redis-server
systemctl start redis
systemctl enable redis

Also disabled the built in firewall but users could allow the web port in as well
systemctl disable firewalld

Awesome, thanks! I will get these modifications into the docs and built into the install script ASAP.
