Ipotesi di implementazione di un server Web di Sezione Allegato B

##

## httpd.conf -- Apache HTTP server configuration file

# Based upon the NCSA server configuration files originally by Rob McCool.

#

# This is the main Apache server configuration file. It contains the

# See for detailed information about

# the directives.

#

# Do NOT simply read the instructions in here without understanding

# consult the online docs. You have been warned.

#

# After this file is processed, the server will look for and process

# unless you have overridden these with ResourceConfig and/or

# AccessConfig directives here.

#

# The configuration directives are grouped into three basic sections:

# whole (the 'global environment').

# 2. Directives that define the parameters of the 'main' or 'default' server,

# which responds to requests that aren't handled by a virtual host.

# These directives also provide default values for the settings

# of all virtual hosts.

# 3. Settings for virtual hosts, which allow Web requests to be sent to

# different IP addresses or hostnames and have them handled by the

# same Apache server process.

#

# Configuration and logfile names: If the filenames you specify for many

# server will use that explicit path. If the filenames do *not* begin

# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"

# with ServerRoot set to "/usr/local/apache" will be interpreted by the

# server as "/usr/local/apache/logs/foo.log".

#
### Section 1: Global Environment

#

# The directives in this section affect the overall operation of Apache,

# can find its configuration files.

#
#

# ServerType is either inetd, or standalone. Inetd mode is only supported on

# Unix platforms.

#

ServerType standalone

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

#

# NOTE! If you intend to place this on an NFS (or otherwise network)

# (available at );

# you will save yourself a lot of trouble.

#

# Do NOT add a slash at the end of the directory path.

ServerRoot "/etc/httpd"

# The LockFile directive sets the path to the lockfile used when Apache

# is compiled with either USE_FCNTL_SERIALIZED_ACCEPT or

# USE_FLOCK_SERIALIZED_ACCEPT. This directive should normally be left at

# its default value. The main reason for changing it is if the logs

# directory is NFS mounted, since the lockfile MUST BE STORED ON A LOCAL

# DISK. The PID of the main server process is automatically appended to

# the filename.

#

LockFile /var/lock/httpd.lock

# PidFile: The file in which the server should record its process

# identification number when it starts.

#

PidFile /var/run/httpd.pid

# ScoreBoardFile: File used to store internal server process information.

# Not all architectures require this. But if yours does (you'll know because

# this file will be created when you run Apache) then you *must* ensure that

# no two invocations of Apache share the same scoreboard file.

#

ScoreBoardFile /var/run/httpd.scoreboard

# In the standard configuration, the server will process this file,

# srm.conf, and access.conf in that order. The latter two files are

# now distributed empty, as it is recommended that all directives

# be kept in a single file for simplicity. The commented-out values

# below are the built-in defaults. You can have the server ignore

# these files altogether by using "/dev/null" (for Unix) or

# "nul" (for Win32) for the arguments to the directives.

#

#ResourceConfig conf/srm.conf

# Timeout: The number of seconds before receives and sends time out.

#

Timeout 300

# KeepAlive: Whether or not to allow persistent connections (more than

# one request per connection). Set to "Off" to deactivate.

#

KeepAlive On

# MaxKeepAliveRequests: The maximum number of requests to allow

# during a persistent connection. Set to 0 to allow an unlimited amount.

# We recommend you leave this number high, for maximum performance.

#

MaxKeepAliveRequests 100

# KeepAliveTimeout: Number of seconds to wait for the next request from the

# same client on the same connection.

#

KeepAliveTimeout 15

# Server-pool size regulation. Rather than making you guess how many

# server processes you need, Apache dynamically adapts to the load it

# sees --- that is, it tries to maintain enough server processes to

# handle the current load, plus a few spare servers to handle transient

# load spikes (e.g., multiple simultaneous requests from a single

# Netscape browser).

#

# It does this by periodically checking how many servers are waiting

# a new spare. If there are more than MaxSpareServers, some of the

# spares die off. The default values are probably OK for most sites.

#

MinSpareServers 5

# Number of servers to start initially --- should be a reasonable ballpark

# figure.

#

StartServers 8

# Limit on total number of servers running, i.e., limit on the number

# of clients who can simultaneously connect --- if this limit is ever

# reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW.

# It is intended mainly as a brake to keep a runaway server from taking

# the system with it as it spirals down...

#

MaxClients 250

# MaxRequestsPerChild: the number of requests each child process is

# allowed to process before the child dies. The child will exit so

# as to avoid problems after prolonged use when Apache (and maybe the

# libraries it uses) leak memory or other resources. On most systems, this

# isn't really needed, but a few (such as Solaris) do have notable leaks

# in the libraries. For these platforms, set to something like 10000

# or so; a setting of 0 means unlimited.

#

# NOTE: This value does not include keepalive requests after the initial

# an initial request and 10 subsequent "keptalive" requests, it

# would only count as 1 request towards this limit.

#

MaxRequestsPerChild 100

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, in addition to the default. See also the

# directive.

#

#Listen 3000

# BindAddress: You can support virtual hosts with this option. This directive

# is used to tell the server which IP address to listen to. It can either

# contain "*", an IP address, or a fully qualified Internet domain name.

# See also the and Listen directives.

#

#BindAddress *

# Dynamic Shared Object (DSO) Support

#

# To be able to use the functionality of a module which was built as a DSO you

# directives contained in it are actually available _before_ they are used.

# Please read the file README.DSO in the Apache 1.3 distribution for more

# details about the DSO mechanism and run `httpd -l' for the list of already

# built-in (statically linked and thus always available) modules in your httpd

# binary.

# User/Group: The name (or #number) of the user/group to run httpd as.

# suggested workaround is to create a user www and use that user.

# NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)

# when the value of (unsigned)Group is above 60000;

# ServerAdmin: Your address, where problems with the server should be

# e-mailed. This address appears on some server-generated pages, such

# as error documents.

# ServerName: allows you to set a host name which is sent back to clients for

# your server if it's different than the one the program would get (i.e., use

# "www" instead of the host's real name).

#

# Note: You cannot just invent host names and hope they work. The name you

# this, ask your network administrator.

# If your host doesn't have a registered DNS name, enter its IP address here.

# You will have to access it by its address (e.g., http://123.45.67.89/)

# anyway, and this will make redirections work in a sensible way.
