Apache 2.0.47 Error when try to run the command httpd -S
 

Hi All Guru,

I encountered the error below when trying to run the command httpd -S to check my configuration. Both my webservers is running on RHEL4 64bit and using IBM HTTP Server 2.0.47. Hope anyone can give me an idea here.

./httpd -S
Segmentation fault

Another server give me a different error.

./httpd -S
./httpd: error while loading shared libraries: libaprutil-0.so.0: cannot open shared object file: No such file or directory


Thanks alot in advance.

Install apr-util and give that a shot.

Hi twantrd,

Thanks alot for your response. I did below but still encounter the error.

up2date apr-util

Fetching Obsoletes list for channel: rhel-x86_64-as-4...

Fetching rpm headers...

Name Version Rel
----------------------------------------------------------


The following packages you requested are already updated:
apr-util
[root@iyp-web3 bin]# ./httpd -S
./httpd: error while loading shared libraries: libaprutil-0.so.0: cannot open shared object file: No such file or directory

Look under /lib. The library probably does exist but under a different name. Do you see a libaprutil-?.so.?. If the library exists as a different filename, make a symlink (ie. libaprutil-0.so.0 -> /lib/the_name_of_the_library_that_exists_here). Give that a shot.

If you don't know how to do this, then run this command and paste it to us.

Hi twantrd,

Thanks alot for your response. Below is a continuous ssh session. Please see below.

./httpd -S
./httpd: error while loading shared libraries: libaprutil-0.so.0: cannot open shared object file: No such file or directory
[root@iyp-web3 bin]# cd ../lib
[root@iyp-web3 lib]# ls -lrt libaprutil-0.so.0
lrwxrwxrwx 1 root root 37 Jun 21 10:18 libaprutil-0.so.0 -> /opt/IBMIHS/lib/libaprutil-0.so.0.9.4

And the real file does exist right? If so, then it seems that it's not looking in the right path? Can you paste us the output of the below command? Thanks.

Hi twantrd,

Thanks alot for your response and kind help. Now I get a new error.

I did google this but no help found.

You get a segfault but apache is running. Hmmm. Is apache working (ie. port 80 open, does it serve pages)??

Also, what happens if you do a ./httpd start instead of ./httpd -S.

You didn't answer my first question :). Is it serving pages? The process appears to be running...

-twantrd

Hi twantrd,

Yes. It's serving the pages for www.yellowpages.com.sg but not www.asiacni.com.sg

Hi twantrd,

Just an update here, I'm using iptables to loadbalance another IP here to load the website www.asiacni.com.sg. Another website on this IP is working fine but not www.asiacni.com.sg

/sbin/iptables -t nat -A PREROUTING -d 165.21.60.68 -j REDIRECT

Make a new subject thread for this as your original question (httpd not running) is now resolved. That way, your problem gets exposed to more people who can assist you better.
