file_cache is not installed

Install the required development packages:

# yum install httpd-devel gcc

Get your current running Apache version :

# httpd -v
Server version: Apache/2.2.15 (Unix)
Server built:   Jan 12 2017 17:09:39

or

# rpm -qv httpd
httpd-2.2.15-56.el6.centos.3.x86_64

Get the Apache source matching your running version from the archive download repository :

http://archive.apache.org/dist/httpd/

(this example would require the following package : http://archive.apache.org/dist/httpd/httpd-2.2.15.tar.gz)

# cd /usr/local/src
# wget http://archive.apache.org/dist/httpd/httpd-2.2.15.tar.gz

Untar:

# tar xvf httpd-2.2.15.tar.gz

Go to the module directory :

# cd httpd-2.2.15/modules/cache

Build the module:

# apxs -i -a -c mod_file_cache.c

The module has been compiled and added in httpd.conf.

Add mod_mem_cache:

apxs -c -i mod_mem_cache.c cache_cache.c cache_pqueue.c cache_hash.c

Check your configuration:


# service httpd configtest

If no error output, then reload the configuration :

service httpd reload

Check the installed modules:

# httpd -M
