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:
Traceback (most recent call last):

system spec both servers:

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.

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)

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 :

I installed the Python libraries on my local PC, I also added my GA-4 Property ID. When I attempt to run the script I get the following error, note that the error actually makes sense because the IP Address failing doesn't have a valid SSL certificate:

Have any of you run into this when attempting to run the quickstart.py script locally?

I attempted to run the script after following the "TODOS". I installed the Google certificates locally. I then tested the IP Address the script is failing on, the address is not secured.
Your connection isn't private
Attackers might be trying to steal your information from 142.250.190.10 (for example, passwords, messages, or credit cards).

I'm trying to connect to a newly created database in Oracle Cloud (https://cloud.oracle.com/db/adb/)
I've copied the connection string from DB Connection > Connection Strings > (One of the three listed.)
Which looks a little like this:
(description= (retry_count=20)(retry_delay=3)(address=(protocol=tcps)(port=1522)(host=adb.uk-london-1.oraclecloud.com))(connect_data=(service_name=abc123xyzredacted.adb.oraclecloud.com))(security=(ssl_server_cert_dn="CN=adwc.eucom-central-1.oraclecloud.com, OU=Oracle BMCS FRANKFURT, O=Oracle Corporation, L=Redwood City, ST=California, C=US")))
I'm authenticating using the "ADMIN" account that was created at DB creation along with its password.

Am I using the wrong connection string? Should I create another user?
Additional:
I've just found this: https://blogs.oracle.com/opal/post/easy-way-to-connect-python-applications-to-oracle-autonomous-databases
So I now have "Network" showing:
Access Type: Allow secure access from specified IPs and VCNs
Access Control List: Enabled Mutual TLS (mTLS)
Authentication: Not Required
Where my IP address is entered in Access Control List.
You have:
Access Control List: Enabled Mutual TLS (mTLS)
which seems incorrect.
This is what my cloud console shows when I have 1-way (aka walletless) authentication enabled:
Network
Access Type: Allow secure access from specified IPs and VCNs
Access Control List: Enabled
Mutual TLS (mTLS) Authentication: Not Required
When you copy the connection string from the cloud console, make sure to select the correct TLS (not mTLS) value in the dropdown box just above, because the connection string changes.
Check your current IP address is in the ACL list, because IPs addresses are often not static !
I have a mysql server on my computer. I did port fowarding on my modem. I checked port is open or not with signal sites and return success answer. When i try connect on my pc with host = "localhost" i returned success answer. But when i try connect mysql server with python.org's shell, i returned connection error same like this:

How can i connect my mysql server ?
In order to encounter this error first do the following:
Make sure the host is in the format 127.0.0.1 and there are no / or \ in the host name
Check if you have specified all the correct info about the server like passwords, user, root, etc
Make sure the server is active and there is no fire wall blocking your access
Remove all the unwanted users from the server
I'm trying to connect to two MySQL databases (one local, one remote) at the same time using Python 3.4 but I'm really struggling. Splitting the problem into three:
Step 1: connect to the local DB. This is working fine
using PyMySQL. (MySQLdb isn't compatible with Python 3.4, of
course.)
Step 2: connect to the remote DB (which needs to
use SSH). I can get it to work from the Linux command prompt but not
from Python... see below.
Step 3: connect to both at the
same time. I think I'm supposed to use a different port for the
remote database so that I can have both connections at the same time
but I'm out of my depth here! If it's relevant then the two DBs will
have different names. And if this question isn't directly related,
please tell me and I'll post it separately.
Unfortunately I'm not really starting in the right place for a newbie... once I can get this working I can happily go back to basic Python and SQL but hopefully someone will take pity on me and give me a hand to get started!
For Step 2, my code is below. It seems to be quite close to the sshtunnel example which answers this question Python - SSH Tunnel Setup and MySQL DB Access - though that uses MySQLdb. For the moment I'm embedding the connection parameters – I'll move them to the config file once it's working properly.
import dropbox, pymysql, shlex, shutil, subprocess
from sshtunnel import SSHTunnelForwarder
import iot_config as cfg
def CloseLocalDB():
localcur.close()
localdb.close()
def CloseRemoteDB():
# Disconnect from the database
# remotecur.close()
# remotedb.close()
# Close the SSH tunnel
# ssh.close()
print("end of CloseRemoteDB function")
def OpenLocalDB():
global localcur, localdb
localdb = pymysql.connect(host=cfg.localdbconn['host'], user=cfg.localdbconn['user'], passwd=cfg.localdbconn['passwd'], db=cfg.localdbconn['db'])
localcur = localdb.cursor()
def OpenRemoteDB():
global remotecur, remotedb
with SSHTunnelForwarder(
('my_remote_site', 22),
ssh_username = "my_ssh_username",
ssh_private_key = "/etc/ssh/my_private_key.ppk",
ssh_private_key_password = "my_private_key_password",
remote_bind_address = ('127.0.0.1', 3308)) as server:
remotedb = None
#Following line gives an error if uncommented
# remotedb = pymysql.connect(host='127.0.0.1', user='remote_db_user', passwd='remote_db_password', db='remote_db_name', port=server.local_bind_port)
#remotecur = remotedb.cursor()
# Main program starts here
OpenLocalDB()
CloseLocalDB()
OpenRemoteDB()
CloseRemoteDB()
This is the error I'm getting:

Thanks in advance.
Answering my own question because, with a lot of help from J.M. Fernández on Github, I have a solution: the example that I copied at the beginning uses port 3308 but port 3306 is the standard. Once I'd changed this it started working.
