First thing first! Install your favourite Bitnami XAMPP for Mac package:
http://www.apachefriends.org/en/xampp-macosx.html
At the time of writing, the latest version is v1.8.2 which includes newest Apache v2.4 as web server. This is where the problem is and we are going to sort this out and compile new mod_auth_mysql.so.
Make sure you setup XAMPP properly with appropriate passwords created for Apache and MySQL and so on…
!!!REMIND!!!
Before your spiritual work, make sure you stop Apache server so nothing should be affected during the compiling process.
The source code of mod_auth_mysql is a bit old to support Apache v2.4 web server whereas a little bit of extra work is required to get APXS compiling working.
Download C source code of mod_auth_mysql:
http://sourceforge.net/projects/modauthmysql/files/modauthmysql/3.0.0/mod_auth_mysql-3.0.0.tar.gz
Extract the mod_auth_mysql-3.0.0.tar.gz file which gives you a folder called "mod_auth_mysql-3.0.0".
Using Terminal command:
$ cd mod_auth_mysql-3.0.0
You will see the source file named "mod_auth_mysql.c" and we are going to work on it.
Download a patch file within the folder and patch it right there as follows:
$ $ curl http://www.zoosau.de/wp-content/uploads/mod_auth_mysql-300-apache-22.patch
$ $ patch < mod_auth_mysql-300-apache-22.patch
The patch fixes some problems for APXS compiling. For Apache v2.4, we have to do some more editing in the file "mod_auth_mysql.c".
Open up editor for the file "mod_auth_mysql.c":
$ open -e mod_auth_mysql.c
Modify the lines as described below:
========================================================== LINE 908: return r->connection->remote_ip; Changed to: return r->connection->client_ip; ========================================================== LINE 1273: const apr_array_header_t *reqs_arr = ap_requires(r); Changed to: const apr_array_header_t *reqs_arr = NULL; ========================================================== LINE 1275: const array_header *reqs_arr = ap_requires(r); Changed to: const array_header *reqs_arr = NULL; ==========================================================
Explanation:
It's a bit technical and requires you to read Apache manual first about new Apache 2.4 which explicitly takes ap_requires() function completely out of core services.
Looking through those forums and finally get something closed to that problem. A possible fix:
http://www.mail-archive.com/pld-cvs-commit@lists.pld-linux.org/msg313889.html
As function ap_requires() is removed from Apache v2.4 API, we can set related reference pointer to NULL in order to skip that problem in mod_auth_mysql.c file.
For the solution of LINE 908, thanks to the blogger on http://cootos.sinaapp.com/?p=94 .
Now comes the actual compiling work.
Reference is here:
http://www.nilspreusker.de/?s=mod_auth_mysql
But we need to modify the paths to port them to those paths in XAMPP for Mac package.
Using Terminal command as follows:
$ $ $ sudo /Applications/XAMPP/bin/apxs -c -i -a -D -lmysqlclient \ -lm -lz -I/Applications/XAMPP/XAMPPfiles/include/ \ -L/Applications/XAMPP/XAMPPfiles/include/ \ -Wc,"-arch x86_64" -Wl,"-arch x86_64" mod_auth_mysql.c
It's a long command which I spilt it into four lines so you may have to recombine them in the text editor before you issue the actual command.
If things are going well, you should see the following output generated by the above command:
/Applications/XAMPP/xamppfiles/build/libtool --silent --mode=compile gcc -std=gnu99 -prefer-pic -I/Applications/XAMPP/xamppfiles/include/c-client -I/Applications/XAMPP/xamppfiles/include/libpng -I/Applications/XAMPP/xamppfiles/include/freetype2 -O3 -L/Applications/XAMPP/xamppfiles/lib -I/Applications/XAMPP/xamppfiles/include -I/Applications/XAMPP/xamppfiles/include/ncurses -arch x86_64 -DDARWIN -DSIGPROCMASK_SETS_THREAD_MASK -no-cpp-precomp -DDARWIN_10 -I/Applications/XAMPP/xamppfiles/include -I/Applications/XAMPP/xamppfiles/include/apr-1 -I/Applications/XAMPP/xamppfiles/include/apr-1 -I/Applications/XAMPP/xamppfiles/include -arch x86_64 -I/Applications/XAMPP/XAMPPfiles/include/ -c -o mod_auth_mysql.lo mod_auth_mysql.c && touch mod_auth_mysql.slo mod_auth_mysql.c: In function 'str_format': mod_auth_mysql.c:891: warning: format '%d' expects type 'int', but argument 8 has type 'long int' /Applications/XAMPP/xamppfiles/build/libtool --silent --mode=link gcc -std=gnu99 -Wl,-rpath -Wl,/Applications/XAMPP/xamppfiles/lib -L/Applications/XAMPP/xamppfiles/lib -I/Applications/XAMPP/xamppfiles/include -arch x86_64 -L/Applications/XAMPP/xamppfiles/lib -L/Applications/XAMPP/xamppfiles -o mod_auth_mysql.la -arch x86_64 -L/Applications/XAMPP/XAMPPfiles/include/ -lmysqlclient -lm -lz -rpath /Applications/XAMPP/xamppfiles/modules -module -avoid-version mod_auth_mysql.lo /Applications/XAMPP/xamppfiles/build/instdso.sh SH_LIBTOOL='/Applications/XAMPP/xamppfiles/build/libtool' mod_auth_mysql.la /Applications/XAMPP/xamppfiles/modules /Applications/XAMPP/xamppfiles/build/libtool --mode=install install mod_auth_mysql.la /Applications/XAMPP/xamppfiles/modules/ libtool: install: install .libs/mod_auth_mysql.so /Applications/XAMPP/xamppfiles/modules/mod_auth_mysql.so libtool: install: install .libs/mod_auth_mysql.lai /Applications/XAMPP/xamppfiles/modules/mod_auth_mysql.la libtool: install: install .libs/mod_auth_mysql.a /Applications/XAMPP/xamppfiles/modules/mod_auth_mysql.a libtool: install: chmod 644 /Applications/XAMPP/xamppfiles/modules/mod_auth_mysql.a libtool: install: ranlib /Applications/XAMPP/xamppfiles/modules/mod_auth_mysql.a chmod 755 /Applications/XAMPP/xamppfiles/modules/mod_auth_mysql.so
Now it's time to modify a working https.conf for Apache v2.4.
In httpd.conf, find those lines with LoadModule * statements and add the following two statements at the bottom of that section:
# # # LoadModule apreq_module modules/mod_apreq2.so LoadModule mysql_auth_module modules/mod_auth_mysql.so #
This make sure the target libraries are called up when Apache starts.
Before you start Apache server again to test if it runs or not, you have one more thing to do. In my experience, Apache server may not start because of libmyqlclient error. This is the case when we have no other MySQL client setup on the Mac before.
All you have to do is creating new symbolic link to let Apache v2.4 find the right library:
$ $ sudo ln -s /Applications/XAMPP/xamppfiles/lib/libmysqlclient.18.dylib \ /usr/lib/libmysqlclient.18.dylib $
Now start your Apache v2.4 web server and see if it's running properly. If yes, you are ready to use mod_auth_mysql module again!
Happy coding!!!
PS: Additionally you'll need to make sure PHP Session is working.
In /Applications/XAMPP/xamppfiles/etc/php.ini, you need to uncomment a line like this:
session.save_path = "/tmp"
This should do the trick;-)
