@lsetiawan

I'm trying to install WOFpy on the production server and I'm getting an error, it seems like it should work, the dev part worked from your documentation but when I try to set it up for production I'm getting an apache error.

@miguelcleon That looks like a problem in your .cfg file https://github.com/ODM2/WOFpy/blob/master/wof/examples/flask/odm2/timeseries/odm2_config_timeseries.cfg#L1 ... is it missing [WOF]?

Also, if I remember correctly you never deployed a "production" (ie, publicly accessible) WOFpy with Apache, did you? All the testing and deployments we're aware of (including Don's) have been with NGINX. So there's still the possibility that there's some Apache quirks that we haven't encountered and will need to figure out, right @lsetiawan?

miguelcleon commented 7 years ago

I did have them running on a development server, and the web services were being served via apache. However I installed an SSL certificate on the development server and now it is not working so I thought I'd try installing it on the production server with a fresh installation of wofpy.

miguelcleon commented 7 years ago

Actually CUAHSI installed the SSL cert, so they are going to look at it otherwise I would try to fix that.

Yea, I've never done WOFpy installation on Apache... Not sure what's going on. From the errors, it looks like the problem is somehow WOFpy is not reading the .cfg file correctly. Sorry 😞

... and of course, it's Friday afternoon! @lsetiawan is actually a bit sick right now, so I suggest he take a break and get back to helping @miguelcleon with this problem on Monday, all refreshed and ready to trouble shoot.

miguelcleon commented 7 years ago

Ok, no problem @lsetiawan feel better!

lsetiawan commented 7 years ago

@miguelcleon Thanks! 👍

miguelcleon commented 7 years ago

@emiliom @lsetiawan and I figured it out. My dao wasn't setup right in runserver.py. I'm seeing more things here but that can wait for next week.

miguelcleon commented 7 years ago

the confusion came here, this did not work: https://github.com/ODM2/WOFpy/blame/master/docs/WOFpyODM2LBR_installation.md#L238

one should instead change the default configuration file parser argument like here: https://github.com/ODM2/WOFpy/blob/master/wof/examples/flask/odm2/timeseries/runserver_odm2_timeseries.py#L35

emiliom commented 7 years ago

Awesome! Let us know on Monday what problems you're still seeing.

For reference, your installation attempts (and the issue of Apache) started in #73. It'll be great to have WOFpy on top of your LCZO database, and to get from you tips about what needs to be done differently to configure it on Apache.

Also, I seriously need to get back to cleaning up the installation instructions ... I've been neglecting that task for far too long.

emiliom commented 7 years ago

@miguelcleon, can we close this issue and #73?

And I'll bug you again: It'll be great to get from you tips about what needs to be done differently to configure it on Apache.

I'll keep bugging you about this :smiling_imp:

miguelcleon commented 7 years ago

Ok, I created a pull request https://github.com/ODM2/WOFpy/pull/199 for the documentation fix I suggested. I can add more for the Apache configuration.

emiliom commented 7 years ago

Closing. Created #218 to follow up on remaining to-do regarding Apache documentation
