I am having a problem with getting this to work on Fedora 3.
I have a full install (i.e. everything) of Fedora 3.
I have then removed the installed libdbi libraries and drivers (i.e. the
rpms - libdbi, libdbi-dbd-mysql & libdbi-dbd-pgsql that were version
I have then installed the latest versions of libdbi from the website
So, I now have libdbi 0.7.2 and libdbi-drivers 0.7.1 installed.
I have then downloaded mod_log_sql-1.99 and extracted the source.
I have downloaded both the diff files and patched the source.
I then successfully ran configure and make and make install.
I then set up a new database called apachelogs and a new database user
with create and insert privileges.
I then create the entries for apache, which I do from an include file as
LoadModule log_sql_module modules/mod_log_sql.so
LoadModule log_sql_mysql_module modules/mod_log_sql_mysql.so
LoadModule log_sql_ssl_module moduels/mod_log_sql_ssl.so
LogSQLDBParam socketfile /var/lib/mysql/mysql.sock
I then add a directive to a virtual host of:
I restart mysql and make sure the debug logging is enabled.
I can log in to the mysql database with the command:
mysql -u username -p password apachelogs
the /var/log/mysqld.log file then shows me the connection and all the
However, when I start apache I get the following in the error_log:

I go to the virtualhost and it writes out the SQL statements to
/tmp/sql-preserve as I expected from the docs).
Looking at that file that seems to have all the right information.
So, why isn't the module able to connect to the local mysql socket file
when the other mysql apps can do so?
There doesn't seem to be anything wrong with the filename or path and it
is all accessible to the apache user who runs apache.
Any help would be most appreciated as I'm running out of things to try.
I could go back to the pre-installed versions of libdbi, but they do not
meet the requirements as stated (i.e. libdbi >= 0.7).
Software versions are:
Fedora core 3 (plus current updates)
Install from source:
So, any ideas?
