Weblogic 12c & Apache 2.4 troubleshooting

Error - libonssys.so: cannot open shared object file:

httpd: Syntax error on line 355 of /etc/httpd/conf/httpd.conf: Syntax error on line 1 of /data/apps/apache2/conf.d/vhost.conf: Cannot load /etc/httpd/modules/mod_wl_24.so into server: libonssys.so: cannot open shared object file: No such file or directory


Solution:

1) Copy all supported Download Oracle WebLogic Web Server Plug-Ins 12c from Oracle website : http://www.oracle.com/technetwork/middleware/webtier/downloads/index-jsp-156711.html
Extract the downloaded archive and find (correct file according to your architecture) mod_wl_24.so (This is for Apache2.4.x) & libonssys.so & libonsssl.so & libdms2.so copy into /etc/httpd/modules/ folder.

2) Set the LD_LIBRARY_PATH inside the /etc/sysconfig/httpd file. 

echo $LD_LIBRARY_PATH first and copy paste the same in httpd file along with /etc/httpd/modules location.

Example in my case:

File: /etc/sysconfig/httpd

Content of the file: (highlighted one is being added newly)

[atg@localhost ~]$ cat /etc/sysconfig/httpd

#

# This file can be used to set additional environment variables for

# the httpd process, or pass additional options to the httpd

# executable.

#

# Note: With previous versions of httpd, the MPM could be changed by

# editing an "HTTPD" variable here.  With the current version, that

# variable is now ignored.  The MPM is a loadable module, and the

# choice of MPM can be changed by editing the configuration file

# /etc/httpd/conf.modules.d/00-mpm.conf.

# 

#

# To pass additional options (for instance, -D definitions) to the

# httpd binary at startup, set OPTIONS here.

#

#OPTIONS=

#

# This setting ensures the httpd process is started in the "C" locale

# by default.  (Some modules will not behave correctly if

# case-sensitive string comparisons are performed in a different

# locale.)

#

LANG=C

LD_LIBRARY_PATH=/lib:/usr/lib:/etc/httpd/modules

3) Post this update restart the apache process as root or sudo user

      service httpd restart
