Pas apache di jalankan keluar error berikut

Syntax error on line 73 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'Order', perhaps mis-spelled or defined by a module not included
in the server configuration

Solusinya, mengaktifkan modul authz_host_module di file config apache

LoadModule authz_host_module modules/mod_authz_host.so

Kalo di apache 2.0.x solusinya aktifkan mod_access

LoadModule access_module modules/mod_access.so

Error messages-nya seperti berikut :

[Thu Jan 06 11:35:46 2011] [warn] (2)No such file or directory: Failed to enable the 'httpready' Accept Filter

hasil dari googling ini disebabkan karena modul kernal “accf_http”, berikut sedikit penjelasan dari modul di atas

This is a filter to be placed on a socket that will be using accept() to
     receive incoming HTTP connections.

     It prevents the application from receiving the connected descriptor via
     accept() until either a full HTTP/1.0 or HTTP/1.1 HEAD or GET request has
     been buffered by the kernel.

     If something other than a HTTP/1.0 or HTTP/1.1 HEAD or GET request is
     received the kernel will allow the application to receive the connection
     descriptor via accept().

     The utility of accf_http is such that a server will not have to context
     switch several times before performing the initial parsing of the
     request.  This effectively reduces the amount of required CPU utilization
     to handle incoming requests by keeping active processes in preforking
     servers such as Apache low and reducing the size of the file descriptor
     set that needs to be managed by interfaces such as select(), poll() or
     kevent() based servers.

     The accf_http kernel option is also a module that can be enabled at run-
     time via kldload(8) if the INET option has been compiled into the kernel.

maka solusinya kita aktifkan modul accf_http via kldload

kldload accf_http

atau untuk membuat modul ini permanent di load oleh kernel, maka kita tambahkan opsi berikut di file /boot/loader.conf

accf_http_load="YES"
