Installing X Protocol in order to use mysql shell - Mac - python

My aim is to connect a MySQL database to a python web scraper I have written.
I have started the process of installing mysql shell, which seems to be the correct version of mysql for my needs. I am following the documentation for downloading X Protocol and am stuck.
Following the instructions to download using MySQL Shell, it says
navigate to the MySQL binaries location (for example, /usr/bin/ on Linux).
Run the following command:
mysqlsh -u user -h localhost --classic --dba enableXProtocol\
Which when I run this command, after being promted to type in my password:
Creating a Classic Session to 'user#localhost'
Enter password:
I then receive this error:
ERROR: 2003 (HY000): Can't connect to MySQL server on 'localhost' (61)
How do I get around this situation?
P.s. I'm not sure if I should be entering 'user' or my actual username 'Frankie'

Error message indicated that you don't have installed MySQL Server.
Firstly, you need to install or upgrade to MySQL 5.7.12 or higher. How to do it is described here https://dev.mysql.com/doc/refman/5.7/en/installing.html

Can't connect mysql database to python via sublime [duplicate]

I am connecting MySQL - 8.0 with MySQL Workbench and getting the below error:
Authentication plugin 'caching_sha2_password' cannot be loaded:
dlopen(/usr/local/mysql/lib/plugin/caching_sha2_password.so, 2): image
not found
I have tried with other client tool as well.
Any solution for this?
you can change the encryption of the password like this.
ALTER USER 'yourusername'#'localhost' IDENTIFIED WITH mysql_native_password BY 'youpassword';
Note: For MAC OS
Open MySQL from System Preferences > Initialize Database >
Type your new password.
Choose 'Use legacy password'
Start the Server again.
Now connect the MySQL Workbench
For Windows 10:
Open the command prompt:
cd "C:\Program Files\MySQL\MySQL Server 8.0\bin"
C:\Program Files\MySQL\MySQL Server 8.0\bin> mysql -u root -p
Enter password: *********
mysql> ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'newrootpassword';
Query OK, 0 rows affected (0.10 sec)
mysql> exit
Alternatively, you can change the my.ini configuration as the following:
[mysqld]
default_authentication_plugin=mysql_native_password
Restart the MySQL Server and open the Workbench again.
I had the same problem, but the answer by Aman Aggarwal didn't work for me with a Docker container running mysql 8.X.
I loged in the container
docker exec -it CONTAINER_ID bash
then log into mysql as root
mysql --user=root --password
Enter the password for root (Default is 'root')
Finally Run:
ALTER USER 'username' IDENTIFIED WITH mysql_native_password BY 'password';
You're all set.
You can change the encryption of the user's password by altering the user with below Alter command :
ALTER USER 'username'#'ip_address' IDENTIFIED WITH mysql_native_password BY
'password';
OR
We can avoid this error by make it work with old password plugin:
First change the authentication plugin in my.cnf file for Linux / my.ini file in Windows:
[mysqld]
default_authentication_plugin=mysql_native_password
Restart the mysql server to take the changes in affect and try connecting via MySQL with any mysql client.
If still unable to connect and getting the below error:
Unable to load plugin 'caching_sha2_password'
It means your user needs the above plugin. So try creating new user with create user or grant command after changing default plugin. then new user need the native plugin and you will able to connect MySQL.
Thanks
Currently (on 2018/04/23), you need to download a development release. The GA ones do not work.
I was not able to connect with the latest GA version (6.3.10).
It worked with mysql-workbench-community-8.0.11-rc-winx64.msi (from https://dev.mysql.com/downloads/workbench/, tab Development Releases).
Ok, wasted a lot of time on this so here is a summary as of 19 March 2019
If you are specifically trying to use a Docker image with MySql 8+, and then use SequelPro to access your database(s) running on that docker container, you are out of luck.
See the sequelpro issue 2699
My setup is sequelpro 1.1.2 using docker desktop 2.0.3.0 (mac - mojave), and tried using mysql:latest (v8.0.15).
As others have reported, using mysql 5.7 works with nothing required:
docker run -p 3306:3306 --name mysql1 -e MYSQL_ROOT_PASSWORD=secret -d mysql:5.7
Of course, it is possible to use MySql 8+ on docker, and in that situation (if needed), other answers provided here for caching_sha2_password type issues do work. But sequelpro is a NO GO with MySql 8+
Finally, I abandoned sequelpro (a trusted friend from back in 2013-2014) and instead installed DBeaver. Everything worked out of the box. For docker, I used:
docker run -p 3306:3306 --name mysql1 -e MYSQL_ROOT_PASSWORD=secret -d mysql:latest --default-authentication-plugin=mysql_native_password
You can quickly peek at the mysql databases using:
docker exec -it mysql1 bash
mysql -u root -p
show databases;
I was installing MySQL on my Windows 10 PC using "MySQL Web Installer" and was facing the same issue while trying to connect using MySQL workbench. I fixed the issue by reconfiguring the server form the Installer window.
Clicking on the "Reconfigure" option it will allow to reconfigure the server. Click on "Next" until you reach "Authentication Method".
Once on this tab, use the second option "Use Legacy Authentication Method (Retain MySQL 5.x Compatibility)".
Keep everything else as is and that is how I solved my issue.
Note: For Linux (Debian, Ubuntu, Mint)
I got this error:
MySQL Error Message: Plugin caching_sha2_password could not be loaded: /usr/lib/x86_64-linux-gnu/mariadb19/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory
I solved it with these steps:
Enter on mysql console: $ mysql -u root -p, if you don't have a password for root user, then:
Use mysql db: mysql> use mysql;
Alter your user for solve the problem: mysql> ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
Exit... mysql> quit;
Done!
like this?
docker run -p 3306:3306 -e MYSQL_ALLOW_EMPTY_PASSWORD=yes -d mysql --default-authentication-plugin=mysql_native_password
mysql -uroot --protocol tcp
Try in PWD
https://github.com/GitHub30/docs/blob/change-default_authentication_plugin/mysql/stack.yml
or You shoud use MySQL Workbench 8.0.11.
Open MySQL Command Line Client
Create a new user with a new pass
Considering an example of a path to a bin folder on top, here's the code you need to run in the command prompt, line by line:
cd C:\Program Files\MySQL\MySQL Server 5.7\bin
MySQL -u root -p
current password...***
CREATE USER 'nativeuser'#'localhost'
IDENTIFIED WITH mysql_native_password BY 'new_password';
Then, you can access Workbench again (you should be able to do that after creating a new localhost connection and using the new credentials to start using the program).
Set up a new local host connection with the user name mentioned above (native user), login using the password (new_password)
Courtesy: UDEMY FAQs answered by Career365 Team
For Windows 10,
Modify my.ini file in C:\ProgramData\MySQL\MySQL Server 8.0\
[mysqld]
default_authentication_plugin=mysql_native_password
Restart the MySQL Service.
Login to MySQL on the command line, and execute the following commands in MySQL:
Create a new user.
CREATE USER 'user'#'localhost' IDENTIFIED BY 'password';
Grant all privileges.
GRANT ALL PRIVILEGES ON * .* TO 'user'#'localhost';
Open MySQL workbench, and open a new connection using the new user credentials.
I was facing the same issue and this worked.
Although this shouldn't be a real
solution, it does work locally if you are stuck
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY '';
This is my databdase definition in my docker-compose:
dataBase:
image: mysql:8.0
volumes:
- db_data:/var/lib/mysql
networks:
z-net:
ipv4_address: 172.26.0.2
restart: always
entrypoint: ['docker-entrypoint.sh', '--default-authentication-plugin=mysql_native_password']
environment:
MYSQL_ROOT_PASSWORD: supersecret
MYSQL_DATABASE: zdb
MYSQL_USER: zuser
MYSQL_PASSWORD: zpass
ports:
- "3333:3306"
The relevant line there is entrypoint.
After build and up it, you can test it with:
$ mysql -u zuser -pzpass --host=172.26.0.2 zdb -e "select 1;"
Warning: Using a password on the command line interface can be insecure.

For those using Docker or Docker Compose, I experienced this error because I didn't set my MySQL image version. Docker will automatically attempt to get the latest version which is 8.
I set MySQL to 5.7 and rebuilt the image and it worked as normal:
version: '2'
services:
db:
image: mysql:5.7
I found that
ALTER USER 'username'#'ip_address' IDENTIFIED WITH mysql_native_password BY 'password';
didn't work by itself. I also needed to set
[mysqld]
default_authentication_plugin=mysql_native_password
in /etc/mysql/mysql.conf.d/mysqld.cnf
on Ubuntu 18.04 running PHP 7.0
Here is the solution which worked for me after MySQL 8.0 Installation on Windows 10.
Suppose MySQL username is root and password is admin
Open command prompt and enter the following commands:
cd C:\Program Files\MySQL\MySQL Server 8.0\bin
mysql_upgrade -uroot -padmin
mysql -uroot -padmin
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY
'admin'
If you are getting this error on GitLab CI like me:
Just change from latest to 5.7 version ;)
# .gitlab-ci.yml
rspec:
services:
# - mysql:latest (I'm using latest version and it causes error)
- mysql:5.7 #(then I've changed to this specific version and fix!)
Open my sql command promt:
then enter mysql password
finally use:
ALTER USER 'username'#'ip_address' IDENTIFIED WITH mysql_native_password BY 'password';
refer:https://stackoverflow.com/a/49228443/6097074
Thanks.
For me this started happening because on a project, I was using Docker image mysql:latest (which was version 5, and which was working fine), and during a later build, the latest version was switched to version 8, and stopped working. I changed my image to mysql:5 and I was no longer getting this error.
This error comes up when the tool being used is not compatible with MySQL8, try updating to the latest version of MySQL Workbench for MySQL8
If you still want to use the new authentication method, the proper solution is to install the mariadb-connector-c package. For Alpine, run:
apk add mariadb-connector-c
This will add the missing caching_sha2_password.so library into /usr/lib/mariadb/plugin/caching_sha2_password.so.
Almost like answers above but may be in simple queries, I was getting this error in my spring boot application along with hibernate after MySQL upgrade. We created a new user by running the queries below against our DB. I believe this is a temp work around to use sha256_password instead of latest and good authentication caching_sha2_password.
CREATE USER 'username'#'localhost' IDENTIFIED WITH mysql_native_password BY 'pa$$word';
GRANT ALL PRIVILEGES ON * .* TO 'username'#'localhost';
MySQLWorkbench 8.0.11 for macOS addresses this.
I can establish connection with root password protected mysql instance running in docker.
If you are trying to connect to a MySQL server from a text-based MySQL client from another computer (be it Docker or not)
Most answers here involve connecting from a desktop client, or ask you to switch to an older authentication method. If you're connecting it with the MySQL client (text-based), I made it work with a Debian Buster in a Docker container.
Say you have the apt system and wget set up, do the following:
sudo apt-get update
sudo apt-get install lsb-release -y
Download a Debian package which update apt sources for you from the MySQL web site.
sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb and select the options you want. In my case I only need MySQL Tools & Connectors to be enabled.
sudo apt-get update
sudo apt-get install mysql-client -y
Done. You can now run the new MySQL client and connect with the new authentication method.
The below solution worked for me
Go to Mysql Workbench -> Server-> Users and Privileges
1.Click Add Account
2.Under Login Tab provide new details and make sure to choose the Authentication Type as standard and choose respective administrative roles and Schema Privileges
Actually MySql allows two type of authentication at the time of installation.
Password Encryption
Legacy Encryption
Read Here
So by checking legacy authentication the issue was resolved.
Try using legacy password while downloading and installing MySql, that helped me.
Or follow the method posted by Santhosh Shivan for Mac OS.
Just downloaded the latest mysqlworkbench which is compatible with the latest encryption:
https://downloads.mysql.com/archives/workbench/
Note: On Mac big Sur, the latest two versions: 8.0.22 and 8.0.23 are buggy and do not work.
Use 8.0.21 until these are fixed
I run docker in M1 (arm64), the direct way of changing in the docker bash does not work for me. Instead, I change the mysql image to be
mysql:8.0.26
and the platform is set as
linux/x86_64
and add default_authentication_plugin=mysql_native_password to my.cnf
Then, you rebuild your container.

jupyter-notebook eith oracle connection problem

I have a problem that I've been trying to solve for a very long time and it seems like I'm missing something very basic.
I use a Linux server with Anaconda, Oracle client, Pycharm and jupyter-notebook installed.
I use python scripts in which I write and read data to Oracle DB, and I use the Cx_oracle extension.
The server has several users with a personal username for each and each of them has sudo privileges.
I performed all the installations on the server with sudo privileges.
When I try to connect from the server to Oracle DB I connect properly.
When I connect to Python on the server itself, I connect properly to Oracle DB.
When I connect using Pycharm and I define ORACLE_HOME=/OracleTools/19.0.0/ in the environment variables, I connect properly to the Oracle DB.
My problem starts when I want to use jupyter-notebook
When I try to connect to the DB I get the error -
DatabaseError: Error while trying to retrieve text for error ORA-12715
I noticed when I execute os.environ I see that it is defined for me:
ORACLE_HOME: /OracleTools/19.0.0/bin
and should be
/OracleTools/19.0.0
So I changed using command os.environ['ORACLE_HOME'] = '/OracleTools/19.0.0'
Then I get an error:
DatabaseError: ORA-12715: invalid character set specified
And of course this change is not permanently saved ...
If on the server itself I execute the env command both in the private user and in sudo I see ORACLE_HOME: /OracleTools/19.0.0 and not ORACLE_HOME: /OracleTools/19.0.0/bin
My questions:
Where does the data I get in the os.environ command come from?
How can I edit them permanently ?
Is this even the problem I'm having or should I check something else?
I manage to import cx_oracle, which means that there is no problem of expansion
Thanks!

Ubuntu MYSQL cannot connect from python script

I need to create a mysql DB for my project. I have a ubuntu server and have followed this guide to install required modules:
https://www.javahelps.com/2018/10/install-mysql-with-phpmyadmin-on-ubuntu.html
After installing everything I can reach the phpmyadmin using the browser 192.168.3.146/phpmyadmin works without any issues:
phpmyadmin home screen
But the problem is when I try to reach the database through the python code, it does not work. My program hangs after mysql.connector.connect and will never print the next print statement.
print("trying MYSQL")
myConnection = mysql.connector.connect(host=192.168.3.146, user='test_user', passwd='test_user123', db='test', autocommit=True)
print("Connection ID:", myConnection)
print(myConnection)
I have previously sucesfully connected to the mysql this way to the mysql server which was created on Raspbian and did not have any issues. It seems that UBUNTU is not as straightforward.
Please can someone suggest me what could be the problem if I can easily reach the database through the web browser but python program fails
UPDATE
Trying out to comment out bind address in the configuration file but still no luck. The configuration file:
enter image description here
I have allowed firewall through port 3306 with the following command:
sudo ufw allow 3306
There is some progress. Now my Python program does not hang on the mysql connection but instead gives me error:
ERROR 1130 (HY000): Host '192.168.3.251' is not allowed to connect to this MySQL server
First of all, I am unsure where does this IP come from 192.168.3.251. The machine am using to connect to the database is configured with static IP and it is 192.168.4.200. I do not know why it says 192.168.3.251
Is the python script running from another machine? If so, maybe the problem is that mysql is listening only in localhost interface. You can change this by editing the file mysqld.cnf located in the /etc/mysql/mysql.conf.d/ folder and comment (with an #) the line that says:
bind-address = 127.0.0.1.
Once you've done this, restart the service this way:
$ sudo systemctl restart mysql.service
And, verify that everything is ok with:
$ systemctl status mysql.service

How to get Python clear-text plugin auth working on Windows (using MySQLdb)?

I have a MariaDB 5.5.57-1ubuntu0.14.04.1 installed on Ubuntu Linux 14.04 and configured with the following to authenticate MySQL users using our OpenLDAP infrastructure via PAM:
# cat /etc/mysql/conf.d/ldap.cnf
[mysqld]
pam-use-cleartext-plugin
plugin-load = auth_pam.so
# cat /etc/mysql/conf.d/ssl.cnf
[mysqld]
ssl-cipher = DHE-RSA-AES256-SHA
ssl-ca=/etc/mysql/ssl/ca-cert.pem
ssl-cert=/etc/mysql/ssl/server-cert.pem
ssl-key=/etc/mysql/ssl/server-key.pem
I've created my user in mysql like this:
MariaDB [(none)]> CREATE user 'ldap1'#'%' IDENTIFIED VIA pam;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON test.* TO 'ldap1'#'%' IDENTIFIED VIA pam REQUIRE SSL;
I can authenticate from a remote Linux host doing this:
mysql -u ldap1 -p -h my.server.net --ssl --enable-cleartext-plugin
When I connect from MySQL Workbench on Windows 7 I can tick 'Enable Cleartext Authentication Plugin' under the Advanced tab (Require SSL of course) and authenticate as well there too.
When I run my Python script, I get the error message below. Anyone know a fix or is there a DLL I need to install?
NOTE:The code I'm using was sent to me from an outside developer and not so sure I can share the code so just posting the error output. If this is not a common problem with a known workaround (It's been difficult finding all the right pieces to do this from both Linux and Windows platforms) I can certainly email said developer and ask about posting watered down version of the connect routine. The code does import MySQLdb to establish the DB connection if it matters.

Superset cannot connect to my MSSQL database

After installing Superset (open source software from Airbnb) on my virtual machine (RHEL, Linux 7.2-11), I cannot add my MSSQL database in the configuration page.
Menu->Sources->Databases->Add
In the SQLAlchemy URI field, I entered :
mssql+pymssql://user:password#host:port/database
Obviously, with my user, password, host, port and database name.
But when I click "Test Connection" I have the following error :
ERROR: {"error": "Connection failed!
The error message returned was:
(pymssql.OperationalError) (18456, 'DB-Lib error message 20018, severity 14:\
General SQL Server error: Check messages from the SQL Server\
DB-Lib error message 20002, severity 9:\
Adaptive Server connection failed (host:port)')"}
I already installed the pymssql package and I do not really know where this error could come from.
I tried to follow these tutorials but, maybe I'm doing it wrong:
http://airbnb.io/superset/installation.html
http://airbnb.io/superset/tutorial.html#connecting-to-a-new-database
What worked for me is the following:
mssql+pymssql://user:pass#address.of.db/?charset=utf8
However, I didn't manage to define a database using this syntax, and in turn couldn't define/find the available tables.
I was also having problem to connect with MSSQL. I was on macOS Catalina. I took the following steps, and it worked:
brew install msodbcsql17 mssql-tools (see: https://learn.microsoft.com/en-us/sql/connect/odbc/linux-mac/install-microsoft-odbc-driver-sql-server-macos?view=sql-server-ver15)
pip install pyodbc
mssql+pyodbc://UserName:Password#HostIP,Port/DBName?driver=ODBC Driver 17 for SQL Server
Mentioning of 'driver=ODBC Driver 17 for SQL Server' in the end is important. (See: https://stackoverflow.com/a/51266453/13150101)
Please try mssql://user:password#host:port/database
