[users@httpd] 1.3.28 - status page won't display
I am an admitted Apache newbie who is trying to get the status page to
display. I have installed Apache 1.3.28 on Red Hat Fedora Core 1.
I compiled with these switches:
===
configure --prefix=/usr/local/etc/httpd --enable-rule=SHARED_CORE
--ssyconfdir=/www/conf --enable-module=rewrite --enable-module=so
--enable-module=status --activate-module=src/modules/php4/libphp4.a
===
I added the following lines to httpd.conf to enable the server status
reports:
httpd.conf, beginning with line 205:
---
LoadModule status_module /usr/lib/httpd/modules/mod_status.so
AddModule mod_status.c
#
# ExtendedStatus controls whether Apache will generate "full" status
# information (ExtendedStatus On) or just basic information
(ExtendedStatus
# Off) when the "server-status" handler is called. The default is Off.
#
ExtendedStatus On
[output omitted]
#
# Allow server status reports, with the URL of
http://servername/server-status
# Change the ".your-domain.com" to match your domain to enable.
#
<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from snort
</Location>
===
But I got this error when trying to start Apache:
[root@snort bin]# ./apachectl start
Syntax error on line 205 of /www/conf/httpd.conf:
Cannot load /usr/lib/httpd/modules/mod_status.so into server:
/usr/lib/httpd/modules/mod_status.so: undefined symbol:
ap_hook_post_config
./apachectl start: httpd could not be started
[root@snort bin]#
===
I commented out httpd.conf lines 205 and 206:
#LoadModule status_module /usr/lib/httpd/modules/mod_status.so
#AddModule mod_status.c
===
Now it starts but I am still not getting status.
[root@snort bin]# ./apachectl start
./apachectl start: httpd started
[root@snort bin]# httpd -l
Compiled in modules:
core.c
prefork.c
http_core.c
mod_so.c
[root@snort bin]# ./apachectl status
Forbidden
You don't have permission to access /server-status on this server.

I get the feeling that I don't fully understand the interaction between
DocumentRoot and that "<Location /server-status>" section in httpd.conf.
httpd.conf:
---
DocumentRoot "/www/servers"
[output omitted]
<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from snort
</Location>
===
I made sure the 'server-status' directory exists and perms are wide
open:
[root@snort servers]# pwd
/www/servers
[root@snort servers]# ls -Rl
.:
total 12
-rwxr-xr-x 1 root root 58 Mar 24 17:20 index.html
drwxrwxrwx 2 root root 4096 Mar 24 17:40 server-status
drwxrwxrwx 3 root root 4096 Mar 24 17:39 snort
./server-status:
total 0
./snort:
total 4
drwxrwxrwx 2 root root 4096 Mar 24 17:39 server-status
./snort/server-status:
total 0
[root@snort servers]#
===
Can anyone give me some hints where to go next?
Thanks,
Jonathan

I have recompiled a few times - always with the same result. Is there
something specific you had in mind that I should change during the
recompile, with the idea of achieving different results? Below is my
configure command line for reference:
===
configure --prefix=/usr/local/etc/httpd --enable-rule=SHARED_CORE
--ssyconfdir=/www/conf --enable-module=rewrite --enable-module=so
--enable-module=status --activate-module=src/modules/php4/libphp4.a
===
Good idea on the using the FC1 package. I hadn't thought of that.
Thanks,
Jonathan

Well, i'm not too sure, but you might as well include 'ldd /path/to/httpd'
output as well just for good measure. My guess is you need to recompile if
apache won't start with mod_status.so because of unresolved symbol. The
LD_LIBRARY_PATH variable might be useful if a library can't be found during
runtime. As a last resort, try using a fedora (redhat) package if you can't
get a compiled version working ... :\

See below:
[root@snort root]# ldd /usr/lib/httpd/modules/mod_status.so
libc.so.6 => /lib/tls/libc.so.6 (0x003d8000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x003c0000)

Hmmm. I looked in apachectl it is not obvious what I am supposed to add.
Further, when I execute 'set' to get a list of environmental variables,
I see no LD_LIBRARY_PATH variable. Maybe that is the problem? If so,
what do you suggest assigning to the variable, given the ldd output
above?
Thanks in advance,

this means a library isn't linked correctly or something might not be compiled
correctly. what does ldd /usr/lib/httpd/modules/mod_status.so return?
you might be able to add edit apachectl and add a path to $LD_LIBRARY_PATH

because /server-status won't work without the module.

My excuse is that I just joined the list this afternoon. ;-)
I went back and looked at the post from George Hester (5:49 pm) which
referred to Location section in httpd.conf. Here's my original
The original order:
><Location /server-status>
> SetHandler server-status
> Order deny,allow
> Deny from all
> Allow from snort
></Location>
Currently:
<Location /server-status>
SetHandler server-status
Order deny,allow
Allow from snort
Deny from all
</Location>
And the results:
[root@snort bin]# ./apachectl status
Index of /server-status

Evidently it is not necessary to have the "LoadModule" statement in
httpd.conf. I still have "LoadModule status_module
/usr/lib/httpd/modules/mod_status.so" and "AddModule mod_status.c"
commented out and the server-status module seems to be working.
Is that the normal output?
