I came across a customer recently that had a module installed on their apache2 installation, but they couldn’t understand why it wasn’t loaded. In this case it was the filter module.
[root@box ~]# yum provides /usr/lib64/httpd/modules/mod_filter.so Loaded plugins: fastestmirror, replace Loading mirror speeds from cached hostfile drivesrvr | 2.2 kB 00:00 httpd-2.2.15-59.el6.centos.x86_64 : Apache HTTP Server Repo : base Matched from: Filename : /usr/lib64/httpd/modules/mod_filter.so httpd24u-2.4.27-1.ius.centos6.x86_64 : Apache HTTP Server Repo : ius Matched from: Filename : /usr/lib64/httpd/modules/mod_filter.so httpd-2.2.15-60.el6.centos.4.x86_64 : Apache HTTP Server Repo : updates Matched from: Filename : /usr/lib64/httpd/modules/mod_filter.so httpd-2.2.15-60.el6.centos.4.x86_64 : Apache HTTP Server Repo : installed Matched from: Other : Provides-match: /usr/lib64/httpd/modules/mod_filter.so You can activated it by adding following line to httpd.conf;
