mod_rewrite problem - unable to restart apache web server

Hi experts,

I have apache_2.0.43 on solaris 8 machine. I tried to configure httpd.conf to set 'Authorization' http header as environment variable as following:

#####################################
LoadModule rewrite_module modules/mod_rewrite.so
 
<Directory "/www/httpd/apache_2.0.43/pcgi">
 RewriteEngine on
 RewriteCond %{HTTP:Authorization} (.*)
 RewriteRule .* - [E=HTTP_AUTHORIZATION:%1]
</Directory>
#####################################

I couldn't restart the Apache because it couldn't find mod_rewrite.so
Please let me know where can I find this module in apache directories. How can I check the list of modules currently loaded on the web server.

Thanks,
Rakesh.

Look in your $APACHE_HOME/modules directory
you should see a mod_rewrite.so

If not, it was not compiled in, to do so you need to do for example:

bash-2.05$ ./configure --prefix=/usr/local/apache --enable-so --enable-rewrite=shared
bash-2.05$ make
bash-2.05# make install

to check which modules you have installed already to to:

http://www.yourserver.com/server-info on a browser as well as lookin in the $APACHE_HOME/modules directory toi see what exists.

I didn't see any .so file in modules directory except httpd.exp. But I got the list of modules using 'httpd -l' and mod_rewrite.so was not there. I will try to recompile apache and test this module on Monday.

Thanks,
Rakesh.

You should have actually 2 lines in your httpd.conf:

LoadModule rewrite_module     /usr/lib/apache/mod_rewrite.so
AddModule mod_rewrite.c

httpd -l will only show you modules built statically i believe.  I run apache 2.0.49 on Solaris 9, with mod_rewrite installed:
---------------
/usr/local/apache/bin#httpd -l
Compiled in modules:
  core.c
  mod_access.c
  mod_auth.c
  mod_include.c
  mod_log_config.c
  mod_env.c
  mod_setenvif.c
  mod_ssl.c
  prefork.c
  http_core.c
  mod_mime.c
  mod_status.c
  mod_autoindex.c
  mod_asis.c
  mod_info.c
  mod_negotiation.c
  mod_dir.c
  mod_imap.c
  mod_actions.c
  mod_so.c
---------------
is what i get when I run httpd -l, now I have mod_rewrite installed, in my httpd.conf I only have:
---------------
LoadModule rewrite_module           modules/mod_rewrite.so
---------------

From the documentation:
(http://httpd.apache.org/docs-2.0/programs/httpd.html)
"-l
Output a list of modules compiled into the server. This will not list dynamically loaded modules included using the LoadModule directive."  

AddModule is only used if the user wants to re-order the prioritzation of his modules and is using the ClearModule feature.

By default, this is not a required option for modules on apache.

Also, did you LOOK for the module mod_rewrite.so on your server? the physical file? yoou are running linux, you most likely ahve locate installed - do "locate mod_rewrite.so" if you dont have your locatedb done, run first updatedb as root.  then execute the locate command.   If you dont have locate/updatedb installed, that is ok, it is a gnu find utility for making life easier when seaching your computer.  

But you should first look to see if the module is already built and installed, you just may be not using it.

Hi,

I am getting 'Access denied (error code 403)' for my web pages when I compiled apache (2.0.43) as following:
############################
bash-2.05$ ./configure --prefix=/usr/local/apache2 --enable-so --enable-module=rewrite --enable-rewrite=shared
bash-2.05$ make
bash-2.05# make install
############################

and added these lines in httpd.conf:

############################
<Directory "/www/httpd/apache_2.0.43/pcgi">
  RewriteEngine on
  RewriteCond %{HTTP:Authorization} (.*)
  RewriteRule .* - [E=HTTP_AUTHORIZATION:%1]
</Directory>
############################

httpd.conf has following statements after above mentioned statements:

############################
<Directory "/www/httpd/apache_2.0.43/pcgi">
    AllowOverride All
    Options None
    Order allow,deny
    Allow from all
</Directory>
############################

My web pages under '/www/httpd/apache_2.0.43/pcgi' directory works fine when I comment these statements:
############################
#<Directory "/www/httpd/apache_2.0.43/pcgi">
#  RewriteEngine on
#  RewriteCond %{HTTP:Authorization} (.*)
#  RewriteRule .* - [E=HTTP_AUTHORIZATION:%1]
#</Directory>
############################

Please help me to reolve this problem.

My httpd.conf already has the following statement after installation:
LoadModule rewrite_module modules/mod_rewrite.so

Thanks,
Rakesh.

You want to pass the mime auth information to your cgi through the var http_authorization.
A few ideas

1. just in case, use a different variable name e.g. MY_HTTP_AUTHORIZATION that you will use in your cgi

2. Log the rewriting process, add these lines to your httpd.conf

RewriteLog "/var/log/httpd/rewrite.log"
RewriteLogLevel 3

try again, then  have a look into /var/log/httpd/rewrite.log

3. Look at the error_log as well, there could be some relevant information

Where should I keep rewrite statements - httpd.conf or .htaccess? Currently, it is in httpd.conf and giving 403 error.

Thanks,
Rakesh.

.htaccess is to be used for a particular directory - you can try as  well ...

Did you check the error_log ?
Did you try the rewrite_log ?
Did you try to use a different variable MY... ?

I tried all three suggestions. I am getting following error in error_log:

###################################
[Wed May 05 15:15:44 2004] [error] [client 128.107.155.203] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /www/httpd/apache_2.0.43/pcgi/btools/proto/auth.cgi
###################################

rewrite.log is empty.

I solved the 403 error, when I added 'Options FollowSymLinks' for the required directory.

Many thanks,
Rakesh.
