mod_auth_mysql problem

Postby sibawe » 07. January 2007 00:57


I'm new here, sorry if this question is obvious...

How do I install mod_auth_mysql ?

The module is packed in the last WINDOWS version but apparently not in the last LINUX version, available in the xampp-linux-1.5.5a.tar.gz.

The library is nowhere to be found in /opt/lampp/modules, or in any other directory in /opt/lampp for that matter.

I doubt that it needs to be compiled from scratch.

Thanks for your answers.

Hi everyone,

Some tinkering was needed to find the solution, here it is.
It works for my configuration, hopefully it will work for others too :D

FYI, I installed xampp-linux1.5.5a., on Fedora4, in the default directory (/opt/lampp)

Login as root (linux commands are preceded by "root>", mysql commands are preceded by "mysql_root>", comments are preceded by "#") , stop all lampp processes.

1/ To install extra modules, you need to install the xampp-linux-devel package => download "xampp-linux-devel-1.5.5a.tar.gz "

2/ root> tar xzvf xampp-linux-devel-1.5.5a.tar.gz -C /opt #to untar in /opt/lampp
This adds the extra libraries you'll need. If you don't do it, you'll have errors while running apxs

3/ fetch the latest source code of mod_auth_mysql at

4/ In my case, I needed to patch the .c file (!!??) for mod_auth_mysql-3.0.0 , since I was getting compile syntax errors involving "mysql_auth_config_rec". Information at this site was sufficient: My patched file is here:

5/ Next, install the module. For LAMPP, you'll need to tell the compiler where to find and mysql.h with the following compile directives :"-L" and "-I" =>
root> /opt/lampp/bin/apxs -c -L/opt/lampp/lib/mysql -I/opt/lampp/include/mysql -lmysqlclient -lm -lz mod_auth_mysql.c
# to generate the module

6/ Next, install the object file in the /opt/lampp/modules directory:
root>apxs -i #to install in modules/
you can check that the library is installed by checking the presence of /opt/lampp/modules/

7/ Modify your /opt/lampp/etc/httpd.conf by adding the following line in the "Dynamic Shared Object (DSO) Support" section:
LoadModule mysql_auth_module modules/

8/ Create the appropriate database in Mysql. Here is an example:
root> mysql -h localhost -u root -p******
mysql_root>create database auth;
mysql_root>create table authorised_users(name varchar(30) primary key,password varchar(50)); # make sure password is big enough to contain sha1 passwords
mysql_root>insert into table authorised_users(name,password) values ('user', sha1('pass')); # I use sha1 passwords
mysql_root>grant all privileges on auth.* to webauth identified by 'webauth'; # create user webauth/webauth to access the database and check the user information

9/ Create the directory that you want to protect:
root>mkdir /opt/lampp/htdocs/secure
add an index.html file in this directory

10/ Create into this directory an .htaccess file with the following:
#this prevents this error : Error 500 The server encountered an internal error or misconfiguration and was unable to complete your request
# in /opt/lampp/logs/error_log : [error] Internal error: pcfg_openfile()
# details at ... ublic.html

AuthBasicAuthoritative Off

# Define Authorisation type

AuthName "MySQL Testing"
AuthType Basic

# Info needed to connect to the database:

AuthMySQLHost localhost
AuthMySQLDB auth
AuthMySQLUser webauth
AuthMySQLPassword webauth
AuthMySQLUserTable authorised_users
AuthMySQLNameField name
AuthMySQLPasswordField password
AuthMySQLPwEncryption sha1
AuthMySQLEnable On


require valid-user

11/ Try to connect to : http://localhost/secure/index.html, it should work ... , it does for me

Good luck
