I am trying to connect to a MySQL server with python connector. I created a new user lcherukuri
with the authentication plugin mysql_native_password
.
But I got the error
mysql.connector.errors.NotSupportedError: Authentication plugin 'caching_sha2_password' is not supported
Can someone help me?
import mysql.connector
cnx = mysql.connector.connect(user='lcherukuri', password='password',
host='127.0.0.1',
database='test')
cnx.close()
Modify Mysql encryption
ALTER USER 'lcherukuri'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
I was facing the same error for 2 days, then finally I found a solution. I checked for all the installed connectors using pip list
and uninstalled all the connectors. In my case they were:
Uninstalled them using pip uninstall mysql-connector
and finally downloaded and installed the mysql-connector-python
from MySQL official website and it works well.
Please install below command using command prompt.
pip install mysql-connector-python
Use pip install mysql-connector-python
Then connect like this:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost", #hostname
user="Harish", # the user who has privilege to the db
passwd="Harish96", #password for user
database="Factdb", #database name
auth_plugin = 'mysql_native_password',
)
pip3 install mysql-connector-python did solve my problem as well. Ignore using mysql-connector module.
For those who couldn't work out because they installed mysql-connector first, I did the following:
1.First on CMD go to the path of 'pip'
2.Use 'pip list' command
3.There would be three packages installed namely six, protobuf and mysql-connector
4.Uninstall each of them separately
5.Now freshly install the mysql-connector-python module
This worked out for me
I uninstalled mysql-connector (I installed following tutorial on w3schools tutorial) and installed mysql-connector-python instead. It worked.
Install mysql connector using the below command.
pip install mysql-connector-python-rf
Use the command to set the privileges.
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY
'very_strong_password';
FLUSH PRIVILEGES;
Use the python command to connect to mysql database
mydb = mysql.connector.connect(
host="localhost",
user="root",
passwd="very_strong_password",
auth_plugin='mysql_native_password')
i try to resolve this error and finally install PyMySQL instead of mysql library and it's working properly.
thanks.
I had this same issue but my resolution was different because this didn't completely work.
I found this on a GitHub forum - copy and paste this into your terminal. You don't have to change your password; it can be the exact same.
ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '{NewPassword}';
You can go to Settings->Project->Project Interpreter and here install latest version of mysql-connector-python package. In my case it was mysql-connector-python 8.0.15.
I had an almost identical error:
Error while connecting to MySQL: Authentication plugin 'caching_sha2_password' is not supported
The solution for me was simple:
My db username/password creds were incorrect. The error was not descriptive of the problem, so I thought I would share this in case someone else runs into this.
Using MySql 8 I got the same error when connecting my code to the DB, using the pip install mysql-connector-python did solve this error.
To have a more permanent solution without going through your code and modifying whatever needs to be modified: Per MySQL 8 documentation, easiest way to fix this is to add the following to your MySQL d file -> restart MySQL server.
This worked for me!
If your MySQL installation must serve pre-8.0 clients and you encounter compatibility issues after upgrading to MySQL 8.0 or higher, the simplest way to address those issues and restore pre-8.0 compatibility is to reconfigure the server to revert to the previous default authentication plugin (mysql_native_password). For example, use these lines in the server option file:
[mysqld]
#add the following file to your MySQLd file
default_authentication_plugin=mysql_native_password
None of the above solution work for me. I tried and very frustrated until I watched the following video: https://www.youtube.com/watch?v=tGinfzlp0fE
pip uninstall mysql-connector
work on some computer and it might not work for other computer.
I did the followings:
pip uninstall mysql-connector
pip uninstall mysql-connector-python
pip install mysql-connector-python
pip install -U mysql-connector-python
this worked for me, if you already have installed mysql-connector-python
and then follow https://stackoverflow.com/a/50557297/6202853 this answer
If you are looking for the solution of following error
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Acces s is denied: 'D:\softwares\spider\Lib\site-packages\libmysql.dll' Consider using the
--user
option or check the permissions.
The solution:
You should add --user
if you find an access-denied error.
pip install --user mysql-connector-python
paste this command into cmd and solve your problem
I had the same problem and passing auth_plugin='mysql_native_password'
did not work, because I accidentally installed mysql-connector
instead of mysql-connector-python
(via pip3). Just leaving this here in case it helps someone.
This question is already answered here and this solution works.
caching sha2 password is not supported mysql
Just try this command :
pip install mysql-connector-python
I also got a similar error
File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\lib\site-packages\mysql\connector\authentication.py", line 191, in get_auth_plugin
"Authentication plugin '{0}' is not supported".format(plugin_name))
mysql.connector.errors.NotSupportedError: Authentication plugin 'caching_sha2_password' is not supported
You have probably installed mysql-connector instead of mysql-connector-python. So you need to install it again for python3:
pip3 install mysql-connector-python
I ran into the same problem as well. My problem was, that I accidentally installed the wrong connector version. Delete your currently installed version from your file system (my path looks like this: C:\Program Files\Python36\Lib\site-packages) and then execute "pip install mysql-connector-python". This should solve your problem
