This is my first time I am trying to install Apache2 HTTP server in a chroot environment. That's why i decided to follow this procedure : http://www.symantec.com/connect/articles/securing-apache-2-step-step

my web server start with successful :

root@ubuntu:/usr/local/apache2/bin/apachectl start
[Tue Oct 29 01:49:15.879868 2013] [core:warn] [pid 10835] AH00117: Ignoring deprecated use of DefaultType in line 60 of /usr/local/apache2/conf/httpd.conf. AH00548: NameVirtualHost has no effect and will be removed in the next release /usr/local/apache2/conf/httpd.conf:81 AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using
127.0.1.1. Set the 'ServerName' directive globally to suppress this message

root@ubuntu:/chroot/httpd/etc# netstat -antu
Active Internet connections (servers and established)

But at the end of part "Chrooting the server" i have always the same problem. When i try to start apache2 in chroot i have always this error :

root@ubuntu:/chroot/httpd/etc# chroot /chroot/httpd /usr/local/apache2/bin/apachectl
chroot: failed to run command `/usr/local/apache2/bin/apachectl': No such file or directory

however my apachectl file exist :

root@ubuntu:/chroot/httpd/etc# ls -l /chroot/httpd/usr/local/apache2/bin/apachectl
-rwxr-xr-x 1 root root 3437 Oct 29 02:28 /chroot/httpd/usr/local/apache2/bin/apachectl

when I use strace to debug, there are errors with coreutils.mo and libc.mo :

root@ubuntu:/chroot/httpd/etc# chroot /chroot/httpd /usr/local/apache2/bin/httpd

using the tutorial I did not find and copie libraries following on my server. I suppose there is no link with coreutils.mo and libc.mo :

/usr/libexec/ld-elf.so.1  
/var/run/ld-elf.so.hints

I don't understand what files i forgot to copy in my chroot environment to be able to start my apache2.

Any ideas ?
