LoadModule weblogic_module */lib/mod_wl_24.so - apache

Question

I have a problem with Apache/2.4.17 (Unix) and the weblogic module (plugin) mod_wl_24.so
For this project I have used the httpd_vhosts.conf configuration under the extra directory (that I have enabled before in httpd.conf whith "Include conf/extra/httpd-vhosts.conf") and i have keep the default configurations in httpd.conf
I'm on arch-linux, but i think this is not relevant...
I download the right version of WL plugin and i had put the WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0 directory under the ServerRoot of apache:
/etc/httpd
drwxr-xr-x 4 root root 4096 4 dic 18.24 .
drwxr-xr-x 100 root root 12288 9 dic 09.57 ..
drwxr-xr-x 5 root root 4096 9 dic 11.02 conf
lrwxrwxrwx 1 root root 22 11 nov 17.33 modules -> /usr/lib/httpd/modules
drwxr-xr-x 5 root root 4096 4 dic 12.48 WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0
when I configure the httpd_vhosts.conf in extra directory of apache for load the plugin:
LoadModule weblogic_module WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0/lib/mod_wl_24.so
and after restart apache, I receive this error:
systemctl status httpd -l

I have correctly set the LD_LIBRARY_PATH on system for the lib directory of mod_wl_24.so:

So, libopmnsecure.so lib is defined and elaborate from system...
I'm little desperate because i can not find a logical explanation for that...
anyone had that such problem before? Any little help would be grateful :)

Answer 1

I have similar issue with Red Hat RHEL7 and apache 2.4.
For this kind of error
Cannot load .../lib/mod_wl_24.so into server: libonssys.so: cannot open shared object file: No such file or directory
Library libonssys.so is given with weblogic httpd module.
under
/etc/ld.so.conf.d/
create a file pluginWeblogic.conf valued with pathToWeblogicPlugin/lib
for this example valued file pluginWeblogic.conf with
/etc/httpd/WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0/lib
and on shell run :
ldconfig
then restart apache :
systemctl restart httpd

Answer 2

Review the following file:
cat /usr/lib/systemd/system/httpd.service
Under [Service] it specifies the EnvironmentFile=/etc/sysconfig/httpd
Update the file /etc/sysconfig/httpd with the LD_LIBRARY_PATH to the Weblogic Plugin
vi /etc/sysconfig/httpd
# Update to include Weblogic Plugin
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/PATH/weblogic-plugins/lib
#
Restart Apache
systemctl stop httpd.service ;
systemctl start httpd.service ;
systemctl status httpd.service

Answer 3

I have found the problem,
The new system control "systemd" don't load the ENV LD_LIBRARY_PATH when i use the "systemctl restart httpd" command... i don't know why, but is clearly, because if i restart the apache with "apachectl restart" the mod_weblogic is load correctly
i hope this help anybody have this problem

Answer 4

There's no need to set the LD_LIBRARY_PATH. You can simply update the LD_LIBRARY_PATH by copying the 'lib' contents to /usr/lib or /usr/lib64

Answer 5

I might be late but I think someone might be helped by the struggle and how it got fixed.
My environment:
Apache/2.4.41
Ubuntu 20.04.3 LTS
Oracle plugin: mod_wl_24.so
The plugins were placed in the path
/usr/lib/apache2/modules
I added the file "weblogic.load" in apache's mods_available path
echo LoadModule weblogic_module /usr/lib/apache2/modules/mod_wl_24.so > /etc/apache2/mods-available/weblogic.load
Starting apache was failing with the below error
/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/weblogic.load: Cannot load /usr/lib/apache2/modules/mod_wl_24.so into
Resolution
export LD_LIBRARY_PATH=/usr/lib/apache2/modules
cd /etc/ld.so.conf.d
echo /usr/lib/apache2/modules > wlsplugin.conf
ldconfig
apachectl start
