Installing on CentOS8 or RHEL8

[Josh Davis]

We have upgraded all of our servers to RHEL8 and I am trying to get ReviewBoard installed. In the past (RHEL7) we installed ReviewBoard from an rpm package.  I can't find one that works with RHEL8. Is there one I have missed?

[David Trowbridge]

Josh,

The RPM hasn't been maintained in a very long time. Installing via the python toolchain is the best way to get running and stay up to date.

Thanks, David. I'll head down that road.

I'm struggling on the installation. This is for a Red Hat 8 machine that has python 3.6 and python 2.7 on it. I've tried installing it with:

python3 -m pip install reviewboard. It seems to work. When I run through rb-site install /some/file/path I always end up with this:

  Installing the site...

Building site directories ... OK

Creating database ... ERROR: <class 'bytes'>
Creating administrator account ... ERROR: <class 'bytes'>
Saving site settings ... ERROR: <class 'bytes'>
Setting up support ... OK
Finishing the install ... ERROR: <class 'bytes'>

Visiting the URL for my server brings up a 500 error. This is what I find in the error log:

[Tue Jan 18 20:47:42.795685 2022] [wsgi:error] [pid 320003:tid 140336662296320] [client 127.0.0.1:46036] Could not load siteconfig: <class 'bytes'>

Any ideas?

[Christian Hammond]

Not sure what would be printing that...

Let's do a quick test:

$ rb-site manage /path/to/sitedir shell

from reviewboard import initialize

initialize()

Let's see if any or all of that passes. If something doesn't, there should at least be a more useful backtrace.

Also, can you show me what `rb-site --version` says?

Some more info that might be useful:

• My installation process was as follows (as root user):
  • yum install gcc python3-devel libffi-devel openssl-devel memcached patch git-core mod_wsgi
    • I had to change python-devel to python3-devel
    • On Red Hat 8, mod_wsgi will install python3-mod_wsgi. Not sure if this is an issue.
      
  • python3 -m pip install mysqlclient
  • python3 -m pip install ReviewBoard
  • rb-site install /var/www/html
  • cp /var/www/html/conf/apache-wsgi.conf /etc/httpd/conf.d/apache-wsgi.conf
  • systemctl restart httpd
    
• I have created a database named reviewboard on a mariadb server.
• I have confirmed that I am able to connect to this db from the terminal of this webserver.

Hi Josh,

I too faced this issue and found latest mysqlclient was not compatible with django 1.11. 

I had to downgrade mysqlclient from 2.1.0 to 2.0.3. 

If you have a staging system you can try to downgrade and check.

Thanks.

Subodh,

That did the trick!  Thanks for the help! I've been banging my head against this one for way too long.

Josh

[Christian Hammond]

Ahh yep. That’s exactly it. There’s a long story there, but it amounts to some backwards-compatibility in mysqlclient that was removed.

We’re putting out a build of Django Evolution next week that will solve this for good.
