Installing Perl on Unix
MySQL Perl support requires that you have installed MySQL client programming support (libraries and
header files). Most installation methods install the necessary files. If you install MySQL from RPM files
on Linux, be sure to install the developer RPM as well. The client programs are in the client RPM, but
client programming support is in the developer RPM.
The files you need for Perl support can be obtained from the CPAN (Comprehensive Perl Archive
Network) at http://search.cpan.org.
The easiest way to install Perl modules on Unix is to use the CPAN module. For example:
shell perl -MCPAN -e shell
cpan install DBI
cpan install DBD::mysql
The DBD::mysql installation runs a number of tests. These tests attempt to connect to the local
MySQL server using the default user name and password. (The default user name is your login name
on Unix, and ODBC on Windows. The default password is “no password.”) If you cannot connect to
the server with those values (for example, if your account has a password), the tests fail. You can use
force install DBD::mysql to ignore the failed tests.
DBI requires the Data::Dumper module. It may be installed; if not, you should install it before
installing DBI.
It is also possible to download the module distributions in the form of compressed tar archives and
build the modules manually. For example, to unpack and build a DBI distribution, use a procedure such
as this:
1. Unpack the distribution into the current directory:
shell gunzip cd DBI-VERSION
3. Build the distribution and compile everything:
shell perl Makefile.PL
shell make
shell make test
shell make install
The make test command is important because it verifies that the module is working. Note that when
you run that command during the DBD::mysql installation to exercise the interface code, the MySQL
server must be running or the test fails.
It is a good idea to rebuild and reinstall the DBD::mysql distribution whenever you install a new
release of MySQL. This ensures that the latest versions of the MySQL client libraries are installed
correctly
