Class com.teradata.jdbc.TeraDriver not found (Python, jaydebeapi module) - python

I am trying to connect to teradata using jaydebeapi.
import jaydebeapi
conn = jaydebeapi.connect('com.teradata.jdbc.TeraDriver',
'jdbc:teradata://serverIP/charset=UTF8,DBS_PORT=1025',
{'user': 'xxx', 'password': 'xxx'},
[r'path_to_teradata_jdbc_driver/tdgssconfig.jar',r'path_to_teradata_jdbc_driver/terajdbc4.jar'])
When I run this script ($python "Run SQL_Java.py") I get the following error:
Traceback (most recent call last): File "Run SQL_Java.py", line 60,
in

raise _RUNTIMEEXCEPTION.PYEXC("Class %s not found" % name) jpype._jexception.RuntimeExceptionPyRaisable:
java.lang.RuntimeException: Class com.teradata.jdbc.TeraDriver not

Am I not specifying path to JDBC drivers correctly?

Try this variant code:
import jaydebeapi
USERNAME="user01"
PASSWORD="password01"
URL_CONNECTION="jdbc:teradata://server01/"
jars=['E:\\jdbc\\tdgssconfig.jar','E:\\jdbc\\terajdbc4.jar']
conn = jaydebeapi.connect('com.teradata.jdbc.TeraDriver', URL_CONNECTION,[USERNAME,PASSWORD], jars)
p.s. likely problem in [r'path_to_teradata_jdbc_driver/tdgssconfig.jar',r'path_to_teradata_jdbc_driver/terajdbc4.jar']

mysql.connector.errors.NotSupportedError: Authentication plugin 'caching_sha2_password' is not supported
I've tried these suggestions I found on stackoverflow :
shutting down mysql.server, installing mysql-connector-python and restarting mysql.server
passing an auth_plugin argument to the connect() method (as seen below)
auth_plugin='mysql_native_password'
made sure MySQL in listening to port 3306 (answer below)
localhost:mysql (LISTEN)
Versions:
mysql Ver 8.0.32 for macos12.6 on x86_64 (Homebrew)
Python 3.9.1
MacOS 12
Managed to fix issue by uninstalling MySQL connector and reinstalling it. Had issues with permissions so make sure you have permissions to read and write in connector directories.
This tutorial might help if your trying to connect to MySQL with MySQL-connector-python :

Can't connect to MySQL server on 'localhost:3306' (10061) During handling of the above exception in python

i wrote a program to check if program can make connection to MySQL server and if cant connect to server print a error message and this is the program that i wrote
import mysql.connector
is_connected = False
def check_connection():
global is_connected
try:
db = mysql.connector.connect(
host="localhost",
user="root",
passwd=""
)
if db.is_connected():
print("Connected to MySQL database")
is_connected = True
except:
print("Unable to connect to MySQL database check if mysql server is running on defaul port which is 3306")
return is_connected
the whole objective here is print a error message when MySQL server is not running so i stop the server and run the file it works fine when in its own file but when it import to another file and call the check_cconnection method its give this error

Connect to MariaDB database on Synology NAS from SQLalchemy in python issue

furthering my question here, I am trying to put this question in a simpler way.
Following this tutorial, I am trying to start a connection to my Mariadb database in my NAS with SQLalchemy remotely. Here is the code:
# Module Imports
import mariadb
import sys
user = "my_name"
passwd = "my_pass"
host = "192.168.1.111"
db = "test"
port= "3307"
# Connect to MariaDB Platform
try:
conn = mariadb.connect(
user=user,
password=passwd,
host=host,
port=3307,
database=db
)
except mariadb.Error as e:
print(f"Error connecting to MariaDB Platform: {e}")
sys.exit(1)
# Get Cursor
cur = conn.cursor()
then I get this error:
ERROR:root:Internal Python error in the inspect module.
Below is the traceback from this internal error.

I have brew installed mariadb-connector-cand ;
brew installed mariadb; and
pip installed PyMySQL.
Would anyone please help?
I echo with #Tim Roberts. Go to your NAS "Installed Package", click the MariaDB 10 app. In it please make sure the databases are sharable over the intranet or internet. It is called TCP/IP connection. Check it and your connection will be working.
This is a point lots of people forget about when they first start up Mariadb.

Mysql database not connecting to python

I am trying to connect python to mysql by this code--
(I am using the mysql.connect library)
import mysql.connector
cnx = mysql.connector.connect(user='root',
password='password',
host='127.0.0.1',
database='db')
print(cnx)
cnx.close()

I have started the mysql sever in workbench and the also checked the status.
Also database named "db" is also there
Also checked if the host is proper.
-->Removed ssl also.
It seems that your MySQL Server version is 8.x and in that case the default MySQL connector is caching_sha2_password. In the other hand your error is maybe because your python client connector does not support this Authentication Plugin and you should explicitly change the Authentication Plugin to the old one (mysql_native_password).
cnx = mysql.connector.connect(user='root', password='password',
host='127.0.0.1', database='db',
auth_plugin='mysql_native_password')

Python3 MySQL SSL Error - mysql.connector

I have spent all day on this and cant figure it out. I have no problems connecting to the remote server using python and the mysql.connector but when i try using SSL I get the following error:

system spec both servers:
Debian 8.2
OpenSSL 1.0.1k 8 Jan 2015
mysql 5.7.X.
python3
pip3
mysql.connector = Connector/Python 2.1.3
I know the ssl connection works with php and cli mysql connections but i can't figure out how to get ssl to work properly. I have also tried to change the ssl protocol in the mysql.connector network.py source. I have also tried with and without use_pure flag. Any help is greatly appreciated.
the python source:
import mysql.connector
config = {
'user' : 'uname',
'password' :'passwd',
'host' : '192.168.1.10',
'database' : 'python',
'ssl_ca' : '/etc/mysql/ssl/client/ca-cert.pem',
'ssl_cert' : '/etc/mysql/ssl/client/client-cert.pem',
'ssl_key' : '/etc/mysql/ssl/client/client-key.pem',
'use_pure' : 'False'
}
con = mysql.connector.connect(**config);
con.close();
I figured it out. Needed to remove the ssl_key and ssl_cert connection arguments, and only supply the ssl_ca and it works like a charm.
