我错过了什么导致出现该错误?
答案1
在 settings.py 中修复:
DATABASES={
'default':
{
'ENGINE':'django.db.backends.oracle',
'NAME':'servicename', # must be the servicename eg. dbname_high,dbname_low,dbname_medium etc.
'USER':'ADMIN',
'PASSWORD':'bhouguspassword',#Please provide the db password here but it can cause issue if you were using '@'
}
}
小路:
ls -lart /usr/lib/oracle/21/
我已将钱包解压到?/network/admin
文件夹中,并将组权限更改为 apache,并chown -R :apache /usr/lib/oracle/21/
确保您已正确设置 TNS_ADMIN、LD_LIBRARY_PATH
