ModuleNotFoundError: No module named 'MySQLdb' Amazon MySQL RDS SQLAlchemy

Question

I am having issues with connecting Amazon AWS MySQL with SQLAlchemy. According to the instruction, I have connected.

app.config[\'SQLALCHEMY_DATABASE_URI\'] = \'         


        

Answer 1

Above issues has been solved with the following:

import pymysql

pymysql.install_as_MySQLdb()

Nothing to change anywhere.

Answer 2

If you use the PyMySQL client to connect to MySQL, your SQLAlchemy connection string needs to start with

 mysql+pymysql://

instead of mysql://.

If you connect with mysql:// then you will need to install the MySQLdb library as shown in the Traceback.

Answer 3

Step 1 If you want to use MySQLDB you need to use one of the following commands. Which one depends on what OS and software you have and use.

easy_install mysql-python (mix os)

pip install mysql-python (mix os/ python 2)

pip install mysqlclient (mix os/ python 3)

apt-get install python-mysqldb (Linux Ubuntu, ...)

cd /usr/ports/databases/py-MySQLdb && make install clean (FreeBSD)

yum install MySQL-python (Linux Fedora, CentOS ...)

For Windows, see this answer: Install mysql-python (Windows)

Step 2:

1. Create Engine

engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)

use the create_engine.pool_recycle option which ensures that a connection will be discarded and replaced with a new one if it has been present in the pool for a fixed number of seconds:

2. Create Connection object

conn = engine.connect()

3. Execute SQL queries

conn.execute("SELECT * From table;")
