webdav vs apache2.2

badger_fruit · June 26, 2008, 2:41pm

ARGH!!!
I have been banging my head trying to get apache2.2 to work as/with webdav.

Although I am fairly new to linux, I am not a total noob lol so followed my nose and tried to get it working.

I discovered plenty of information on what webdav is and so on and a lovely website mod_dav Installation and Configuration which has apache install instructions. The problem is, I think these relate to Apache 1.3.x as when I run the command

./configure --with-apache=/usr/local/apache2

(which is where apache2 defaults its install to) I am told

checking for static Apache module support… no - Unable to locate /usr/local/apache2/src/include/httpd.h
checking for dynamic Apache module support (via APXS)… no
configure: error: You need to point --with-apache at the base Apache source code directory

and the installer quits.
I compiled apache2.2 from the source code (stored in /home/badger_fruit/httpd/) so tried

./configure --with-apache=/home/badger_fruit/httpd

but received the same error

checking for static Apache module support… no - Unable to locate /home/badger_fruit/httpd/src/include/httpd.h
checking for dynamic Apache module support (via APXS)… no
configure: error: You need to point --with-apache at the base Apache source code directory

i did a

find / -name httpd.h

as root and it found two entries:-

(1) /usr/local/apache2/include/httpd.h
(2) /home/badger_fruit/httpd/include/httpd.h

(1) is the one that Apache2.2 installs
(2) is the one I compiled from

Question: Is there a way of changing where the webdav installer (./configure) looks for these files?
I think if I can do this then it might just work (or at least move on to another error!!)

<UPDATE> So i messed around with the file CONFIGURE and replaced instances of “src/include” with just “include”, there were only 5 so I am fairly certain that this should have changed the path OK.

When i run
./configure --with-apache=/home/badger_fruit/httpd

All seems well

checking for C compiler default output... a.out

configure: creating ./config.status

the next step according to the webdav webpage (mod_dav Installation and Configuration) is to ‘make’ and ‘make install’

make fails with numerous errors (a sample of which are shown below)

Any ideas anyone?

Sorry for the additional ‘reply’ but it seems you’re limited to how long you can leave a post before you edit it again :\

Ok, so I was having a poke around in my httpd source code directory and noticed under the “modules” folder, a folder called “dav”; in there, three additional folders “fs”, “lock” and “main”.

I couldn’t find documented anywhere, but does apache2.2 come with webdav already and it’s just a case of re-compiling with “./configure --withdav” (or something similar)??

ken_yap · June 27, 2008, 1:57pm

It looks like the DAV module has been included in Apache since 2.0

Overview of new features in Apache 2.0 - Apache HTTP Server

If you see either:

/usr/lib64/apache2/mod_dav.so
/usr/lib/apache2/mod_dav.so

then it’s already included and all you had to do was enable it in /etc/sysconfig/apache2.

Isn’t that a bummer?

awojcicki · June 27, 2008, 4:32pm

Hi

As stated before it’s already compiled with dav support. Just add the modules “dav” and “dav_fs” in /etc/sysconfig/apache2 and as well depending on your needs add to /etc/apache2/httpd.conf:

DavLockDB /var/lib/apache2/dav/lockdb

and in between

Dav on

Create the directory /var/lib/apache2/dav and change the rights:

$> chown wwwrun /var/lib/apache2/dav
$> chgrp www /var/lib/apache2/dav
$> chmod 755 /var/lib/apache2/dav

badger_fruit · June 27, 2008, 4:52pm

lol, yeah, well i have been making some serious progress ove r the past hour or so since my last post!

I re-compiled and make/installed apache thusly

./configure --enable-dav

Which then included the webdav stuff needed, well, sort of(!). Running into no other problems, before I started the apache service, I went into httpd.conf and added

LoadModule dav_module /usr/local/apache2/include/mod_dav.h

before the directory directive and also a a LockDB file

DavLockDB myDavLock

Finally, added

Dav On

into a Directory directive.

The next step was to start the apache server, fingers crossed and a following wind, I promptly received an error message stating

/usr/local/apache2/bin/httpd: error while loading shared libraries: libexpat.so.0: cannot open shared object file: No such file or directory

Not to be beaten at this stage, I did a quick goooooooogle search and discovered I needed libexpat0 and libexpat1.

Firing up yast2 I installed them and tried once more.
This time, I was told by apache that

httpd: Syntax error on line 132 of /usr/local/apache2/conf/httpd.conf: module dav_module is built-in and can’t be loaded

Commented out my original

LoadModule dav_module /usr/local/apache2/include/mod_dav.h

and tried again, SUCCESS!!! Apache started with no errors or warnings, hoorah said I, I’d best update my post with my findings

So, my next step is to get sunbird installed and configured to use this server

So far, considering (under Windows) Sunbird version 0.8 doesn’t seem to work at all (example, selecting “Create New Calendar” does not prompt me to define a new calendar) and version 0.7 refuses to go beyond entering the name of a new calendar, this battle may go on for some time …

badger_fruit · June 27, 2008, 6:13pm

Oh, just a quick follow up question, can someone tell me how I can test that all this is actually working as webdav?

I browse to http://localhost and get the standard “it works!” message but no DAVLock file is created etc (which I would expect is because im not making any dav calls etc?)

Thanks once again

A commonly used function of WebDAV is to DragNDrop a file to a website directory (with proper permissions set) to upload a file.
