Configuring Django to use remote mysql server?

问题:

I am trying configure a Django application to use mysql.

I want to use the mysql server available in my network and don't want to install a local copy.

But when I am trying to install mysqldb it needs mysql_config from Mysql!

What should I do if I want to use the mysql server in another machine?

sh: mysql_config: command not found
Traceback (most recent call last):
  File "setup.py", line 15, in <module>
    metadata, options = get_config()
  File "~/Dev/MySQL-python-1.2.3c1/setup_posix.py", line 43, in get_config
    libs = mysql_config("libs_r")
  File "~/Dev/MySQL-python-1.2.3c1/setup_posix.py", line 24, in mysql_config
    raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found

Tried downloading the MySQL files and pointed to "mysql_config" and built mysqldb.

But when I tried to import mysqldb I get:

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build/bdist.macosx-10.5-i386/egg/MySQLdb/__init__.py", line 19, in <module>
  File "build/bdist.macosx-10.5-i386/egg/_mysql.py", line 7, in <module>
  File "build/bdist.macosx-10.5-i386/egg/_mysql.py", line 6, in __bootstrap__
ImportError: dlopen(/tmp/MySQL_python-1.2.3c1-py2.5-macosx-10.5-i386.egg-tmp/_mysql.so, 2): Library not loaded: /usr/local/mysql/lib/libmysqlclient_r.15.dylib
  Referenced from: /tmp/MySQL_python-1.2.3c1-py2.5-macosx-10.5-i386.egg-tmp/_mysql.so

Any hint on what the error is?

Thanks

I finally got MySQLdb compiled without installing MySQL server in my MacOSX.

The steps:

1. Download appropriate MySQL package (tar) not install version and unpack
2. Download MySQLdb wrapper from MySQL Python bindings
3. Unpack MySQLdb
4. Edit site.cfg to point to mysql_config into the directory you have downloaded
5. Follow the instructions in MySQLdb (essentially build & install)
6. Copy the file libmysqlclient_r.15.dylib from your 'mysql/lib' folder to /usr/local/mysql/lib (assuming you have choosen threadsafe version)
7. Now you are ready to use MySQLdb with any MySQL server
8. You can test the installation using: python >>> import MySQLdb

You need to install mysql's client libraries on the machine running Django so it can connect to a remote MySQL server. Both plain libmysqlclient and python's mysql driver. Further details depend on the platform you are running this on.

回答3:

Install a pre-compiled version of the MySQLdb driver. Most Linux distributions provide it in their repositories -- for example, in Debian and Ubuntu it's named python-mysqldb.

Also, as this does not involve programming, it would be best moved to Superuser.
