I am trying to get started with the following github package: py-gameday.
I installed mysql with brew mysql and created a root password:
> mysqladmin -u root password 'xxx'
I then created a user:
> mysql -uroot -p
Enter password: xxx
CREATE USER 'josh'#'localhost' IDENTIFIED BY 'yyy';
Just in case, I reset the password again:
SET PASSWORD FOR 'josh'#'localhost' = PASSWORD('yyy');
and I then updated mydb.ini with:
[db]
user=josh
password=yyy
db=gameday
I finally tried running the following:
$ mysql -D gameday < gameday.sql -p
Enter password:
ERROR 1044 (42000): Access denied for user 'josh'#'localhost' to database 'gameday'
In this last step, I tried entering 'xxx' and 'yyy', but none of them worked. Why?
You need to GRANT access for the user 'josh' to the database 'test'.
GRANT ALL ON test.* TO 'josh'#'localhost';
As long as you don't have NO_AUTO_CREATE_USER set, you can skip the CREATE USER... the following will create the USER and GRANT access in one hit...
GRANT ALL ON test.* TO 'josh'#'localhost' IDENTIFIED BY 'yyy';
You have to also set privileges for that user
GRANT ALL ON test.* TO 'josh'#'localhost';

I had a problem entering the password directly through the python program
When I do something in PostgreSQL, it asks for a database password and here
How can I enter the database password through python so that it is entered in the requested field

I am trying to connect to MySQL database in Flask as follows:
mysql = MySQL()
app.config['MYSQL_HOST'] = 'localhost'
app.config['MYSQL_USER'] = 'root'
app.config['MYSQL_PASSWORD'] = 'password'
app.config['MYSQL_DATABASE_DB'] = 'myDB'
mysql.init_app(app)
I am getting the following error:
pymysql.err.OperationalError: (1045, "Access denied for user 'myusername'#'localhost' (using password: NO)")
I tried reinstalling XAMPP but to no avail.
I have 2 issues:
Why am I getting the error for 'myusername' instead of 'root'?
How can I solve this issue?
SOLUTION:
I needed to grant the correct privilege to the specific user#localhost in MySQL.
By default in XAMPP root user doesn't have password, you can create a new one doing the following steps:
Click Admin next to MySQL on the XAMPP Control Panel to bring up the phpMyAdmin.
Choose the mysql database on the left.
Then, choose the SQL tab on the top and run the following statement:
SET Password=PASSWORD('password');
But, instead I highly recommend to create a new user:
CREATE USER 'myuser'#'%' IDENTIFIED BY 'password';
CREATE DATABASE myDB;
GRANT ALL PRIVILEGES ON myDB.* TO 'myuser'#'localhost';
I am trying to host a Python/Mysql project online with PythonAnywhere. When I attempt to connect to the database with: (host and password changed obviously)
conn = mysql.connector.connect(host='host',user="BobbyQ",password='password',db='mm-database')
I get this error:
mysql.connector.errors.ProgrammingError: 1044 (42000): Access denied for user 'BobbyQ'#'%' to database 'mm-database'
If I run SHOW GRANTS from Mysql console I get this:
mysql> SHOW GRANTS;
+------------------------------------------------------------------------------------------------+
| Grants for BobbyQ#% |
+------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'BobbyQ'#'%' IDENTIFIED BY PASSWORD <secret> WITH MAX_USER_CONNECTIONS 3 |
| GRANT ALL PRIVILEGES ON `BobbyQ$default`.* TO 'BobbyQ'#'%' |
| GRANT ALL PRIVILEGES ON `BobbyQ$mm-database`.* TO 'BobbyQ'#'%' |
+------------------------------------------------------------------------------------------------+
I should be able to connect to the database at this point but I don't why I can't. How can I solve?
With sudo user connect to the database (in the terminal) and create newuser:
CREATE USER 'newuser'#'localhost' IDENTIFIED BY 'user_password';
then go to the mysql database with this command :
USE MYSQL
and give all access to the user (newuser) with :
GRANT ALL PRIVILEGES ON database_name.* TO 'username'#'localhost';
Write the name of the desired database instead of database_name and the desired username instead of username.
Finally :
FLUSH PRIVILEGES;
I have just installed mysql on Mac OSX and can easily open it in a shell and gain access to the databases and tables that come with it.
Now I want to create a database in Python using mysql-connector/python
Before doing that I figured it would be wise to set a user name and password in mysql.
I have tried using the following but get error messages.
My GOAL is to set a user name and a password so that I may simply provide it to mysql-connector for python, and ultimately execute sql queries from the python environment. Here is what I tried at the mysql command prompt:
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('newpwd');
And I get the error message:
ERROR 1044 (42000): Access denied for user ''#'localhost' to database 'mysql'
So I tried the UPDATE METHOD:
UPDATE mysql.user SET Password = PASSWORD('newpwd')
WHERE User = 'root';
and I get the error message:
ERROR 1142 (42000): UPDATE command denied to user ''#'localhost' for table 'user'
So does anyone know why I get denied and how I can make the changes to create a user and a password that I may ultimately use in mysql connect in the python environment?
Sounds like you are not properly authenticated. Make sure you are authenticated with root user
Access denied for user ''#'localhost' to database 'mysql'
should look like
Access denied for user 'root'#'localhost' to database 'mysql'
Otherwise you are not logged in as root, but rather as an anonymous user.
Ofc, when you are logged in with root, you won'T get that message, but you would get it for any username that does not have the proper rights.
start your query with authentication
mysql -u USERNAME -pPASSWORD -h HOSTNAMEORIP DATABASENAME
example:
mysql --port=3307 --host=127.0.0.1 -u root --password=thisismypass test -e "LOAD DATA LOW_PRIORITY LOCAL INFILE '%pathuser%' INTO TABLE `user_log`...."
in your case probably
mysql -u root "SET PASSWORD FOR 'root'#'localhost' = PASSWORD('newpwd');"
I'm trying to connect python with MySQL, but I get this error:
OperationalError: (1045, "Access denied for user 'root'#'localhost' (using password: NO)")
I'm trying to solve it for 6 hours and I fail. Can any one please help me ?
it means that you forgot the password parameter, which in mysql is not required.
from a unix command line:
$ mysql -u root
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: NO)
$ mysql -u root -p
Enter password:
<typing password>
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 47
Server version: 5.1.37-1ubuntu5.5 (Ubuntu)
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
not exactly the same as logging from python,
but it's the same error, and most likely means that in your case the password argument did not make it to mysql at all.
when I type the wrong password I get a very different error on the command line:
$ mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
You didn't specified your root password.
If you are accessing mysql from remote computer... root user is by default limited to localhost connections only. Try running this to enable access from anywhere:
GRANT ALL PRIVILEGES ON *.* TO root#'%' IDENTIFIED BY "YOUR_ROOT_PASSWORD";
FLUSH PRIVILEGES;
Also check your firewall settings.
import MySQLdb
cxn = MySQLdb.connect(host = 'localhost',user = 'root',passwd = 'password', db = 'yourdatabase')
So you need to know what your password is and you need to have created a database with:
CREATE DATABASE yourdatabase;
from the mysql command line as described above.
I was getting this error because I had quotes in my config file.
[mysql]
username: 'uuuu'
password: 'pppp'
host: 'localhost'
database: 'dddd'
should have been
[mysql]
username: uuuu
password: pppp
host: localhost
database: dddd
If you don't see any value in front of the password column when you do
SELECT user, host, password FROM mysql.user;
within your mysql
In your python script don't specify the password
for example
import MySQLdb
db = MySQLdb.connect(host="localhost", # your host, usually localhost
user="root", # your username
passwd="", # your password
db="dynamo",
port = 3306) # name of the data base
# you must create a Cursor object. It will let
# you execute all the queries you need
cur = db.cursor()
# Use all the SQL you like
cur.execute("select * from SomeTable limit 10")
# print all the first cell of all the rows
for row in cur.fetchall():
print(row[0])
db.close()
