I am using MySQL 8 on my development box. I'm running 5.7 on production servers.
But, version 8 is working fine for me. I too had issues when I first installed version 8, but it wasn't with web2py connecting to it. My problems had more to do with interchanging data between version 5.7 and 8 and the way data exports and imports performed. To the original post. Have you seen this? https://stackoverflow.com/questions/45368336/error-keyerror-255-when-executing-pymysql-connect Can you possibly update pymysql on your system? I'm wondering if you have an older version. -Jim On Wednesday, April 22, 2020 at 2:16:36 AM UTC-5, Kevin Keller wrote: > > I think there is an issue with web2py not supporting mysql version 8 and > above. > > > > On Wed, 22 Apr 2020, 03:20 Jim S, <[email protected] <javascript:>> wrote: > >> In your second post above you're connecting to mysql with user usertest >> and a password. >> >> In you web2py example you're connecting with user root. >> >> I'm guessing that is not the issue but can you confirm that you're using >> the same user and password connecting via mysql and via web2py? >> >> -Jim >> >> On Tuesday, April 21, 2020 at 7:59:52 PM UTC-5, L c wrote: >>> >>> no idea ? >>> >>> Le mercredi 22 avril 2020 02:12:43 UTC+2, L c a écrit : >>>> >>>> if i try to create a new app with that it does not work, why ?? i don't >>>> know first time it happens. mysql-server well installed , with sqlite it >>>> works fine ... i don't know what to do , thank you again for your help >>>> >>>> dbun = DAL('mysql://root:mypwd@localhost:3306/4test', pool_size=0) >>>> #dbun = DAL("sqlite://storage.sqlite") >>>> dbun.define_table('personnel', >>>> Field('login', type = 'string' , length = 25 ), >>>> Field('nom', type = 'string' , length = 20 ), >>>> migrate=True) >>>> >>>> >>>> >>>> >>>> >>>> >>>> Le mercredi 22 avril 2020 02:05:33 UTC+2, L c a écrit : >>>>> >>>>> No >>>>> >>>>> Le mercredi 22 avril 2020 01:41:39 UTC+2, Jim S a écrit : >>>>>> >>>>>> Is the DB on a separate server from the web application? >>>>>> >>>>>> Jim >>>>>> >>>>>> >>>>>> On Tue, Apr 21, 2020, 5:59 PM L c <[email protected]> wrote: >>>>>> >>>>>>> New server >>>>>>> same app >>>>>>> same credentials >>>>>>> thank you >>>>>>> >>>>>>> >>>>>>> Le mardi 21 avril 2020 22:04:43 UTC+2, Jim S a écrit : >>>>>>>> >>>>>>>> Is this all running on the same machine? >>>>>>>> >>>>>>>> I'm assuming you haven't changed your app at all, the database >>>>>>>> server is just new.
