mod_cloudflare not work

I install the mod_cloudflare by following command. but I found the mod_cloudflare do not work, the $_SERVER['REMOTE_ADDR'] return IP of CloudFlare.

I have checked the /usr/local/apache/conf/httpd.conf,  there is no # on the LoadModule cloudflare_module  modules/mod_cloudflare.so. so the mod_cloudflare should be loaded.

Any suggestion?


yum install libtool git -y

git clone https://github.com/cloudflare/mod_cloudflare.git && cd mod_cloudflare

/usr/local/apache/bin/apxs -a -i -c mod_cloudflare.c

systemctl restart httpd && /usr/local/apache/bin/httpd -M|grep cloudflare

I confirmed, not works.

Somebody know how to fix this error:

/usr/local/apache/bin/apxs -a -i -c mod_cloudflare.c
apxs:Error: /usr/bin/apu-1-config not found!.
