==================== MySQLdb Installation ==================== .. contents:: .. Prerequisites ------------- + Python 3.2 or higher * http://www.python.org/ * Red Hat Linux: - Make sure you have the Python development headers and libraries (python-devel). + distribute * http://pypi.python.org/pypi/distribute/ + MySQL 3.23.32 or higher * http://www.mysql.com/downloads/ * Versions lower than 3.22 definitely WON'T WORK. * Versions lower than 3.22.19 might not work. * MySQL-3.22 might work but isn't supported anymore. It's very old. * MySQL-3.23 ought to work, but it's pretty elderly. * MySQL-4.0 is supported, but not tested and slightly discouraged. * MySQL-4.1 is supported. The prepared statements API is not supported, and won't be until MySQLdb-1.3 or 2.0, if ever. * MySQL-5.0 is supported and tested, including stored procedures. * MySQL-5.1 is supported (currently a release candidate) but untested. It should work. * MySQL-6.0 is sorta-kinda-supported (currently alpha) but untested. It should work. * Drizzle <https://launchpad.net/drizzle> is a fork of MySQL. So far the C API looks really similar except everything is renamed. Drizzle support probably won't happen in 1.2. There may be have to be an entirely different module, but still using DB-API. * MaxDB, formerly known as SAP DB (and maybe Adabas D?), is a completely different animal. Use the sapdb.sql module that comes with MaxDB. * Red Hat Linux packages: - mysql-devel to compile - mysql and/or mysql-devel to run * MySQL.com RPM packages: - MySQL-devel to compile - MySQL-shared if you want to use their shared library. Otherwise you'll get a statically-linked module, which may or may not be what you want. - MySQL-shared to run if you compiled with MySQL-shared installed * Transactions (particularly InnoDB tables) are supported for MySQL-3.23 and up. You may need a special package from your vendor with this support turned on. + zlib * Required for MySQL-3.23 and newer. * Red Hat Linux - zlib-devel to compile - zlib to run + openssl * May be needed for MySQL-4.0 or newer, depending on compilation options. If you need it, you probably already have it. - you may need openssl-devel on some platforms + C compiler * Most free software-based systems already have this, usually gcc. * Most commercial UNIX platforms also come with a C compiler, or you can also use gcc. * If you have some Windows flavor, you usually have to pay extra for this, or you can use Cygwin_. .. _Cygwin: http://www.cygwin.com/ Building and installing ----------------------- The setup.py script uses mysql_config to find all compiler and linker options, and should work as is on any POSIX-like platform, so long as mysql_config is in your path. Depending on which version of MySQL you have, you may have the option of using three different client libraries. To select the client library, edit the [options] section of site.cfg: embedded use embedded server library (libmysqld) if True; otherwise use one of the client libraries (default). threadsafe thread-safe client library (libmysqlclient_r) if True (default); otherwise use non-thread-safe (libmysqlclient). You should always use the thread-safe library if you have the option; otherwise you *may* have problems. static if True, try to link against a static library; otherwise link against dynamic libraries (default). You may need static linking to use the embedded server. Finally, putting it together:: $ tar xfz MySQL-python-1.2.1.tar.gz $ cd MySQL-python-1.2.1 $ # edit site.cfg if necessary $ python setup.py build $ sudo python setup.py install # or su first Windows ....... I don't do Windows. However if someone provides me with a package for Windows, I'll make it available. Don't ask me for help with Windows because I can't help you. Generally, though, running setup.py is similar to above:: C:\...> python setup.py install C:\...> python setup.py bdist_wininst The latter example should build a Windows installer package, if you have the correct tools. In any event, you *must* have a C compiler. Additionally, you have to set an environment variable (mysqlroot) which is the path to your MySQL installation. In theory, it would be possible to get this information out of the registry, but like I said, I don't do Windows, but I'll accept a patch that does this. On Windows, you will definitely have to edit site.cfg since there is no mysql_config in the MySQL package. Zope .... If you are using a binary package of Zope, you need run setup.py with the python executable that came with Zope. Otherwise, you'll install into the wrong Python tree and Zope (ZMySQLDA) will not be able to find _mysql. Binary Packages --------------- I don't plan to make binary packages any more. However, if someone contributes one, I will make it available. Several OS vendors have their own packages available. RPMs .... If you prefer to install RPMs, you can use the bdist_rpm command with setup.py. This only builds the RPM; it does not install it. You may want to use the --python=XXX option, where XXX is the name of the Python executable, i.e. python, python2, python2.4; the default is python. Using this will incorporate the Python executable name into the package name for the RPM so you have install the package multiple times if you need to support more than one version of Python. You can also set this in setup.cfg. Red Hat Linux ............. MySQL-python is pre-packaged in Red Hat Linux 7.x and newer. This includes Fedora Core and Red Hat Enterprise Linux. You can also build your own RPM packages as described above. Debian GNU/Linux ................ Packaged as `python-mysqldb`_:: # apt-get install python-mysqldb Or use Synaptic. .. _`python-mysqldb`: http://packages.debian.org/python-mysqldb Ubuntu ...... Same as with Debian. Gentoo Linux ............ Packaged as `mysql-python`_. :: # emerge sync # emerge mysql-python # emerge zmysqlda # if you use Zope .. _`mysql-python`: http://packages.gentoo.org/search/?sstring=mysql-python BSD ... MySQL-python is a ported package in FreeBSD, NetBSD, and OpenBSD, although the name may vary to match OS conventions.
