I want to move away from PHP a little and learn Python. In order to do web development with Python I'll need a framework to help with templating and other things.
I have a non-production server that I use to test all of web development stuff on. It is a Debian 7.1 LAMP stack that runs MariaDB instead of the common MySQL-server package.
Yesterday I installed Django and created my first project called firstweb. I have not changed any settings yet.
Here is my first big piece of confusion. In the tutorial I followed the guy installed Django, started his first project, restarted Apache, and Django just worked from then on. He went to his browser and went to the Django default page with no problems.
Me however, I have to cd into my firstweb folder and run
python manage.py runserver myip:port
And it works. No problem. But I'm wondering if it is supposed to work like this, and if this will cause problems down the line?
My second question is that I want to set it up so it uses my MySQL database. I go into my settings.py under /firstweb/firstweb and I see ENGINE and NAME but I'm not sure what to put here.
And then in the USER, PASSWORD, and HOST areas is this my database and its credentials? If I am using localhost can I just put localhost in the HOST area?
Andy's answer helps but if you have concern on exposing your database password in your django setting, I suggest to follow django official configuration on mysql connection: https://docs.djangoproject.com/en/1.7/ref/databases/
Quoted here as:
# settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/path/to/my.cnf',
},
}
}
# my.cnf
[client]
database = NAME
user = USER
password = PASSWORD
default-character-set = utf8
To replace 'HOST': '127.0.0.1' in setting, simply add it in my.cnf:
# my.cnf
[client]
database = NAME
host = HOST NAME or IP
user = USER
password = PASSWORD
default-character-set = utf8
Another OPTION that is useful, is to set your storage engine for django, you might want it in your setting.py:
'OPTIONS': {
'init_command': 'SET storage_engine=INNODB',
}
mysqlclient
sudo pip3 install mysqlclient
if you get error:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-dbljg4tx/mysqlclient/
then:
1. sudo apt install libmysqlclient-dev python-mysqldb
2. sudo pip3 install mysqlclient
Modify settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'website',
'USER': 'root',
'PASSWORD': '',
'HOST': '127.0.0.1',
'PORT': '3306',
'OPTION': {'init_command':"SET sql_mode='STRICT_TRANS_TABLE',"},
}
}
settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django',
'USER': 'root',
'PASSWORD': '*****',
'HOST': '***.***.***.***',
'PORT': '3306',
'OPTIONS': {
'autocommit': True,
},
}
}
then:
python manage.py migrate
if success will generate theses tables:
auth_group
auth_group_permissions
auth_permission
auth_user
auth_user_groups
auth_user_user_permissions
django_admin_log
django_content_type
django_migrations
django_session
and u will can use mysql.
this is a showcase example ,test on Django version 1.11.5: Django-pool-showcase
Follow the given steps in order to setup it up to use MySQL database:
1) Install MySQL Database Connector :
sudo apt-get install libmysqlclient-dev
2) Install the mysqlclient library :
pip install mysqlclient
3) Install MySQL server, with the following command :
sudo apt-get install mysql-server
4) Create the Database :
i) Verify that the MySQL service is running:
systemctl status mysql.service
ii) Log in with your MySQL credentials using the following command where -u is the flag for declaring your username and -p is the flag that tells MySQL that this user requires a password :
mysql -u db_user -p
iii) CREATE DATABASE db_name;
iv) Exit MySQL server, press CTRL + D.
5) Add the MySQL Database Connection to your Application:
i) Navigate to the settings.py file and replace the current DATABASES lines with the following:
# Database
# https://docs.djangoproject.com/en/2.0/ref/settings/#databases
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/etc/mysql/my.cnf',
},
}
}
...
ii) Next, let’s edit the config file so that it has your MySQL credentials. Use vi as sudo to edit the file and add the following information:
sudo vi /etc/mysql/my.cnf
database = db_name
user = db_user
password = db_password
default-character-set = utf8
6) Once the file has been edited, we need to restart MySQL for the changes to take effect :
systemctl daemon-reload
systemctl restart mysql
7) Test MySQL Connection to Application:
python manage.py runserver your-server-ip:8000
Run these commands
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
pip install pymysql
pip install mysqlclient
Then configure settings.py like
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_db',
'HOST': '127.0.0.1',
'PORT': '3306',
'USER': 'root',
'PASSWORD': '123456',
}
}
Enjoy mysql connection
To the very first please run the below commands to install python dependencies otherwise python runserver command will throw error.
sudo apt-get install libmysqlclient-dev
sudo pip install MySQL-python
Then configure the settings.py file as defined by #Andy and at the last execute :
python manage.py runserver
Have fun..!!
python3 -m pip install mysql-connector
pip install mysqlclient
These commands helpful to settingup the mysql db in django without errors
You must create a MySQL database first. Then go to settings.py
file and edit the 'DATABASES'
dictionary with your MySQL credentials:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'YOUR_DATABASE_NAME',
'USER': 'YOUR_MYSQL_USER',
'PASSWORD': 'YOUR_MYSQL_PASS',
'HOST': 'localhost', # Or an IP that your DB is hosted on
'PORT': '3306',
}
}
Here is a complete installation guide for setting up Django to use MySQL on a virtualenv:
http://codex.themedelta.com/how-to-install-django-with-mysql-in-a-virtualenv-on-linux/
As all said above, you can easily install xampp first from https://www.apachefriends.org/download.html Then follow the instructions as:
http://localhost:80
and database at port 3306
, and PhpMyadmin at http://localhost/phpmyadmin/
Edit your settings.py
file like:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'HOST': '127.0.0.1',
'PORT': '3306',
'USER': 'root',
'PASSWORD': '',
}}
Install the following packages in the virtualenv (if you're using django on virtualenv, which is more preferred):
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
That's it!! you have configured Django with MySQL in a very easy way.
Now run your Django project:
python manage.py migrate
python manage.py runserver
Actually, there are many issues with different environments, python versions, so on. You might also need to install python dev files, so to 'brute-force' the installation I would run all of these:
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
pip install pymysql
pip install mysqlclient
You should be good to go with the accepted answer. And can remove the unnecessary packages if that's important to you.
If you are using python3.x then Run below command
pip install mysqlclient
Then change setting.py like
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB',
'USER': 'username',
'PASSWORD': 'passwd',
}
}
