#Install Mysql with Python and Django Debian/Derivatives 

#To install we need to have some dependencies in the system for now we will show on
#Debian and Derivatives.

#But first install updates and MySQL

```
$ sudo apt-get update
$ sudo apt-get upgrade
```	

# ** NOTE: ** 
#Each System has its commands for updating, if your machine is not derived from Debian ** look for them **

##Install MySQL

```
$ sudo apt-get install mysql-server mysql-client
Passwd for 'root' user: <password>
```

#At the end we execute this command to give more security to our BD

```
$ mysql_secure_installation
```

#Check carefully the changes that will be made, the first question is the passwd for root,
#IF you want to keep or change it, and continue with other security questions.

##Create a database and a user for the DB

#Now we will create the DB that will be connected to DJango and a User with Passwd to access it.
#There are two ways to do this:

```
echo "CREATE DATABASE <DATABASENAME>;" | mysql -u root -p
echo "CREATE USER '<DATABASEUSER>'@'localhost' IDENTIFIED BY '<PASSWORD>';" | mysql -u root -p
echo "GRANT ALL PRIVILEGES ON <DATABASENAME>.* TO '<DATABASEUSER>'@'localhost';" | mysql -u root -p
echo "FLUSH PRIVILEGES;" | mysql -u root -p
```

#So they should put their passwd of mysql in each line or
#they can also do it of the following way

```
$ mysql -u root -p
```

#Enter your passwd and then do the following.

```
CREATE DATABASE <DATABASENAME>;
CREATE USER '<DATABASEUSER>'@localhost IDENTIFIED BY '<PASSWORD>';
GRANT ALL PRIVILEGES ON <DATABASENAME>.* TO '<DATABASEUSER>'@localhost;
FLUSH PRIVILEGES;
exit
```

#We Check Dependencies
#There are only a few dependencies but you have to be sure

```
$ sudo apt-get install libmysqlclient-dev python-dev
```

#So far it's all just proceed to install pip in our virtual environment or globally

```
$ sudo -H pip install mysql-python
```

#As you can see now you can create DB and Users for each Django Project
