Even though the X32/M32 firmware has been updated frequently over the years with new improvements and features, it does not seem to be able to keep up with the numerous feature requests. Composite key, or composite primary key, refers to cases where more than one column is used to specify the primary key of a table. In such cases, all foreign keys will also need to include all the columns in the composite key.

MySQL databases on PythonAnywhere are protected by a firewall, so externalcomputers can't access them.

However, if you have a paid account, you can access your MySQL databasefrom outside using a technique called an SSH tunnel, which essentially makesa secure SSH connection to our systems, then sends the MySQL stuff over it.

There are a number of ways to do this. The first thing you need to know isthe SSH hostname for your account:

  • If your account is on our global, US-based system at www.pythonanywhere.com, then the SSH hostname is ssh.pythonanywhere.com
  • If your account is on our EU-based system at eu.pythonanywhere.com, then the SSH hostname is ssh.eu.pythonanywhere.com

Armed with that, you can do one of the following:

MySQL Workbench

If you're running MySQL Workbench, you can configure it to connect use a tunnel with settings like this using 'Standard TCP/IP over SSH':

SettingValue
SSH Hostname:your SSH hostname
SSH Username:your PythonAnywhere username
SSH Password:the password you use to log in to the PythonAnywhere website
SSH Key file:should not be necessary when you specify the password
MySQL Hostname:your PythonAnywhere database hostname, eg. yourusername.mysql.pythonanywhere-services.com
MySQL Server Port:3306
Username:your PythonAnywhere username
Password:your PythonAnywhere database password
Default Schema:your database name, eg yourusername$mydatabase
  • You may also need to allow ssh login based management as one of the mysql workbench options under server connections -> remote management.

  • It's also a good idea to set the Edit -> Preferences -> SQL Editor -> DBMS_Connection keep alive interval setting to 200, to avoid any 'lost connection' issues due to our 5-minute connection timeout.

From Python code

If you're running Python code on your local machine, and you want it to accessyour MySQL database, you can install the sshtunnel packageand then use code like this:

Download

This example uses the mysql-connector library, but you can use any MySQLlibrary you like.

If you have trouble with the SSH Tunnel connection, the project provides ahelpful troubleshooting guide

Klipfolio

Klipfolio is an online business dashboard tool; you can connect it to yourPythonAnywhere MySQL server by setting up a datasource and telling it to use an SSH tunnel.The settings are:

SettingValue
Host:your PythonAnywhere database hostname, eg. yourusername.mysql.pythonanywhere-services.com
Port:3306
Database:your database name, eg yourusername$mydatabase
Driver:MySQL
Username:your PythonAnywhere database username
Password:your PythonAnywhere database password

Then click the arrow next to the 'Use an SSH tunnel' option -- this will revealnew Host, Port, Username and Password inputs:

SettingValue
Host:your SSH hostname
Port:22
Username:your PythonAnywhere username
Password:the password you use to log in to the PythonAnywhere website

JetBrains PyCharm

You can set up the SSH tunnelling from the SSH/SSL tab of the PyCharm connectionsetup dialog:

  • The 'proxy host' should be your SSH hostname (see the options for that at the top of this help page)
  • The 'proxy user' should be your PythonAnywhere username
  • The 'proxy password' should be the password you use to log in to our website (not your MySQL password)

You should also be aware that there is a problem in PyCharm where it does notrecognise database names with dollar signs in them (which all databases haveon PythonAnywhere. They have posted a workaround for that on their site.

Sequel-Pro

Contributed by Baodong Liu

I prefer Sequel-Pro, which is a very good looking and easy to use interface foryou to have the convenience of managing your database. The limitation is thatSequel-Pro can only be installed on a Mac computer, not Windows.

Initial installation

It is important to upgrade Sequel-Pro to 1.1.2, the most recent version.After you install the 1.1.2 version, you will need to move the downloadedsoftware to your MacBook Applications. You can simply go to Finder to check theDevices from there. You will find your downloaded Sequel-Pro. Just move it toApplications in Finder. You will need to confirm this from the admin authority.After you successfully move Sequel-Pro to Applications, you can launch it fromyour Applications.

The first thing you need to do on Sequel-Pro is to configure local server andimport a database from your own computer directory. You will enter the followinginformation from the 'Standard' option of connections.

SettingValue
Host:127.0.0.1
Username:root
Password:root
Port:8889

After entering the above information, you will be able to see that you arerunning your SQL testing environment. Just select 'Add Database' from the'Choose Database' drop-down menu. You can then test it from there, and import alocal database to Sequel-Pro.

Connecting to PythonAnywhere

Now, you are ready to connect your Sequel-Pro to your database that you havepreviously set up on to Pythonanywhere.

To do this, you will need to use the SSH option, rather than the Standard oneyou used earlier. You will then be asked to provide information on both MySQLHost and SSH Host information. You will need to enter all the required boxescorrectly to have the access to your PythonAnywhere database. Here are thedetails:

SettingValue
Name:(you can write whatever you want)
MySQL Host:your PythonAnywhere database hostname, eg. yourusername.mysql.pythonanywhere-services.com
Username:your PythonAnywhere database username
Password:your PythonAnywhere database password
Database:(optional, so you can leave it blank)
Port:3306
SSH Host:your SSH hostname
SSH User:your PythonAnywhere username
SSH Password:the password you use to log in to the PythonAnywhere website
SSH Port:(optional, so you can leave it blank)

After entering all the above information correctly, you will successfully beconnected to your database in Pythonanywhere. Your fun of managing your owndatabase starts right away.

Manual SSH tunnelling

For other tools that you want to run on your own machine, you can set up a tunnel that pretends to be a MySQL serverrunning on your machine but actually sends data over SSH to your PythonAnywhereMySQL instance. If you're using a Mac or Linux, you probably already have theright tool installed -- the ssh command. If you're using Windows, see the 'Using PuTTY on Windows'section below.

Using SSH (Linux/Mac)

As long as you're not running a MySQL instance locally, just invoke SSH locally(that is, on your own machine -- not on PythonAnywhere) like this, replacingusername with your PythonAnywhere username and yoursshhostname withyour SSH hostname:

That -L option means 'forward LOCAL port 3306 to REMOTE hostusername.mysql.pythonanywhere-services.com port 3306'.

If you are running a MySQL instance locally, then it will probably already be usinglocal port 3306, which means that the ssh command won't be able to. You can modify your SSH invocationto use any other port -- this one would use the local post 3333.

REMEMBER You need to keep your this ssh process open at all times whileyou're accessing your PythonAnywhere MySQL server from your local machine! Assoon as that closes, your forwarded connection is also lost.

After all of that, you'll have a server running on your computer (hostname127.0.0.1, port 3306 -- or 3333 or something else if you have MySQL running locally),which will forward everything on to the MySQL server on PythonAnywhere.

Now skip down to the 'Using the tunnel' section below.

Using PuTTY on Windows

The ssh command is not normally installed on Windows, but you can use a toolcalled PuTTY instead:

Download and install PuTTY from here. Once you've done that:

  • Start PuTTY and enter your SSH hostname into the 'Host name' field
  • In the 'Category' tree on the left, open Connection -> SSH -> Tunnels
  • If you don't have a MySQL database running on your local machine, enter 'Source port' 3306. If you do have one running, use some other port, for example 3333.
  • Set 'Destination' to yourusername.mysql.pythonanywhere-services.com:3306.
  • Click the 'Open' button, and enter the username and password you would use to log in to the PythonAnywhere website.
  • Once it's connected, leave PuTTY running -- it will manage the SSH tunnel.

After all of that, you'll have a server running on your computer (hostname127.0.0.1, port 3306 -- or 3333 or something else if you have MySQL running locally),which will forward everything on to the MySQL server on PythonAnywhere.

Using the tunnel

At this point, you should be able to run code that connects to MySQL using this local server.For example, you could use the code that is inside the with statement in the'From Python code' section above.

One thing to watch out for, however -- some MySQL clients treat the hostname localhost as special,meaning 'connect to the local server over a domain socket'. What you want to dois force it to connect to your local machine on port 3306, and you can do thisby specifying 127.0.0.1 for the host instead of localhost. For example, to usethe command-line mysql client you'd invoke it like this:

Or, if you had to use port 3333 because you had a local MySQL server:
