Linux-apache httd.conf文件详解

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

# configuration directives that give the server its instructions.

# See <URL:http://httpd.apache.org/docs/2.2/> for detailed information.

# In particular, see

# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>

# for a discussion of each configuration directive.

#

#

# Do NOT simply read the instructions in here without understanding

# what they do.  They're here only as hints or reminders.  If you are unsure

# consult the online docs. You have been warned.

#

# The configuration directives are grouped into three basic sections:

#  1. Directives that control the operation of the Apache server process as a

#     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

# of the server's control files begin with "/" (or "drive:/" for Win32), the

# 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 "/etc/httpd" will be interpreted by the

# server as "/etc/httpd/logs/foo.log".

#

### Section 1: Global Environment

#

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

# such as the number of concurrent requests it can handle or where it

# can find its configuration files.

#

#

# Don't give away too much information about all the subcomponents

# we are running.  Comment out this line if you don't mind remote sites

# finding out what major optional modules you are runnin

ServerTokens OS

//在出现错误页的时候是否显示服务器操作系统的名称，ServerTokens Prod为不显示

# 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)

# mounted filesystem then please read the LockFile documentation

# (available at <URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile>);

# you will save yourself a lot of trouble.

#

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

ServerRoot "/etc/httpd"

//用于指定Apache的运行目录，服务启动之后自动将目录改变为当前目录，在后面使用到的所有相对路径都是想对这个目录下

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

# identification number when it starts.  Note the PIDFILE variable in

# /etc/sysconfig/httpd must be set appropriately if this location is

# changed.

PidFile run/httpd.pid

//记录httpd守护进程的pid号码，这是系统识别一个进程的方法，系统中httpd进程可以有多个，但这个PID对应的进程是其他的父进程

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

Timeout 60

//第二次连接前服务器与客户端断开的时间

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

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

KeepAlive Off

//是否持续连接（因为每次连接都得三次握手，如果是访问量不大，建议打开此项，如果网站访问量比较大关闭此项比较好），修改为：KeepAlive On 表示允许程序性联机

# 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

//限制一个连接的最大请求数，0表示不限制

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

# same client on the same connection.

#

KeepAliveTimeout 15

//

##

## Server-Pool Size Regulation (MPM specific)

//apche的两种工作模式 prefork模式和worker模式

# prefork MPM

# StartServers: number of server processes to start

# MinSpareServers: minimum number of server processes which are kept spare

# MaxSpareServers: maximum number of server processes which are kept spare

# ServerLimit: maximum value for MaxClients for the lifetime of the server

# MaxClients: maximum number of server processes allowed to start

# MaxRequestsPerChild: maximum number of requests a server process serves

<IfModule prefork.c>

StartServers       8

MinSpareServers    5

MaxSpareServers   20

ServerLimit      256

MaxClients       256

MaxRequestsPerChild  4000

</IfModule>

系统默认的模块，表示为每个访问启动一个进程（即当有多个连接公用一个进程的时候，在同一时刻只能有一个获得服务）。

StartServer 开始服务时启动8个进程，最小空闲5个进程，最多空闲20个进程。

ServerLimit 设置了MaxClients最大允许配置的数值

MaxClient 限制同一时刻客户端的最大连接请求数量超过的要进入等候队列。

MaxRequestsPerChild 每个进程生存期内允许服务的最大请求数量，0表示永不结束

# worker MPM

# StartServers: initial number of server processes to start

# MaxClients: maximum number of simultaneous client connections

# MinSpareThreads: minimum number of worker threads which are kept spare

# MaxSpareThreads: maximum number of worker threads which are kept spare

# ThreadsPerChild: constant number of worker threads in each server process

# MaxRequestsPerChild: maximum number of requests a server process serves

<IfModule worker.c>

StartServers         4

MaxClients         300

MinSpareThreads     25

MaxSpareThreads     75

ThreadsPerChild     25

MaxRequestsPerChild  0

</IfModule>

为Apache配置线程访问，即每对WEB服务访问启动一个线程，这样对内存占用率比较小。

ServerLimit服务器允许配置进程数的上限。

ThreadLimit每个子进程可能配置的线程上限

StartServers启动两个httpd进程，

MaxClients同时最多能发起250个访问，超过的要进入队列等待，其大小有ServerLimit和ThreadsPerChild的乘积决定

ThreadsPerChild每个子进程生存期间常驻执行线程数，子线程建立之后将不再增加

MaxRequestsPerChild每个进程启动的最大线程数，如达到限制数时进程将结束，如置为0则子线程永不结束

### Section 2: 'Main' server configuration

#

# The directives in this section set up the values used by the 'main'

# server, which responds to any requests that aren't handled by a

# <VirtualHost> definition.  These values also provide defaults for

# any <VirtualHost> containers you may define later in the file.

#

# All of these directives may appear inside <VirtualHost> containers,

# in which case these default settings will be overridden for the

# virtual host being defined.

#

#

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

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

# as error documents.  e.g. admin@your-domain.com

//管理员的邮箱，如果出现问题，会在首页显示

ServerAdmin root@localhost

#

# ServerName gives the name and port that the server uses to identify itself.

# This can often be determined automatically, but we recommend you specify

# it explicitly to prevent problems during startup.

#

# If this is not set to valid DNS name for your host, server-generated

# redirections will not work.  See also the UseCanonicalName directive.

#

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

# You will have to access it by its address anyway, and this will make

# redirections work in a sensible way.

#ServerName www.example.com:80

默认是不需要指定的，服务器通过名字解析过程来获得自己的名字，但如果解析有问题（如反向解析不正确），或者没有DNS名字，也可以在这里指定IP地址，当这项不正确的时候服务器不能正常启动。前面启动Apache时候提示正在启动  httpd：httpd: apr_sockaddr_info_get() failed forjustin httpd: Could not  reliably determine the server's fully qualified domain name, using  127.0.0.1forServerName，解决方法就是启动该项把www.example.com:80修改为自己的域名或者直接修改为localhost

# UseCanonicalName: Determines how Apache constructs self-referencing

# URLs and the SERVER_NAME and SERVER_PORT variables.

# When set "Off", Apache will use the Hostname and Port supplied

# by the client.  When set "On", Apache will use the value of the

# ServerName directive.

UseCanonicalName Off

//如果客户端提供了主机名和端口，Apache将会使用客户端提供的这些信息来构建自引用URL。这些值与用于实现基于域名的虚拟主机的值相同，并且对于同样的客户端可用。CGI变量SERVER_NAME和SERVER_PORT也会由客户端提供的值来构建

# DocumentRoot: The directory out of which you will serve your

# documents. By default, all requests are taken from this directory, but

# symbolic links and aliases may be used to point to other locations.

DocumentRoot "/var/www/html"

//apache的默认web站点目录路径，结尾不要添加斜线

#

# Each directory to which Apache has access can be configured with respect

# to which services and features are allowed and/or disabled in that

# directory (and its subdirectories).

#

# First, we configure the "default" to be a very restrictive set of

# features.  

   #行为对根目录的限制

<Directory />

    Options FollowSymLinks  #followsymlinks表示允许使用符号链接，默认为禁用

    AllowOverride None       # 表示禁止用户对目录配置文件(.htaccess进行修改)重载，普通站点不建议开启

</Directory>

# Note that from this point forward you must specifically allow

# particular features to be enabled - so if something's not working as

# you might expect, make sure that you have specifically enabled it

# below.

#

#

# This should be changed to whatever you set DocumentRoot to.

<Directory "/var/www/html">

#

# Possible values for the Options directive are "None", "All",

# or any combination of:

#   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

#

# Note that "MultiViews" must be named *explicitly* --- "Options All"

# doesn't give it to you.

#

# The Options directive is both complicated and important.  Please see

# http://httpd.apache.org/docs/2.2/mod/core.html#options

# for more information.

#

    Options Indexes FollowSymLinks

#

# AllowOverride controls what directives may be placed in .htaccess files.

# It can be "All", "None", or any combination of the keywords:

#   Options FileInfo AuthConfig Limit

#

    AllowOverride None

#

# Controls who can get stuff from this server.

#

    Order allow,deny

    Allow from all

</Directory>

//对/var/www/html目录的一个权限的设置，options中Indexes表示当网页不存在的时候允许索引显示目录中的文件，FollowSymLinks是否允许访问符号链接文件。有的选项有ExecCGI表是否使用CGI，如Options  Includes ExecCGI  FollowSymLinks表示允许服务器执行CGI及SSI，禁止列出目录。SymLinksOwnerMatch表示当符号链接的文件和目标文件为同一用户拥有时才允许访问。AllowOverrideNone表示不允许这个目录下的访问控制文件来改变这里的配置，这也意味着不用查看这个目录下的访问控制文件，修改为：AllowOverride  All  表示允许.htaccess。Order对页面的访问控制顺序后面的一项是默认选项，如allow，deny则默认是deny，Allowfromall表示允许所有的用户，通过和上一项结合可以控制对网站的访问控制

# UserDir: The name of the directory that is appended onto a user's home

# directory if a ~user request is received.

#

# The path to the end user account 'public_html' directory must be

# accessible to the webserver userid.  This usually means that ~userid

# must have permissions of 711, ~userid/public_html must have permissions

# of 755, and documents contained therein must be world-readable.

# Otherwise, the client will only receive a "403 Forbidden" message.

#

# DefaultLanguage and AddLanguage allows you to specify the language of

# a document. You can then use content negotiation to give a browser a

# file in a language the user can understand.

#

# Specify a default language. This means that all data

# going out without a specific language tag (see below) will

# be marked with this one. You probably do NOT want to set

# this unless you are sure it is correct for all cases.

#

# * It is generally better to not mark a page as

# * being a certain language than marking it with the wrong

# * language!

#

# DefaultLanguage nl

#

# Note 1: The suffix does not have to be the same as the language

# keyword --- those with documents in Polish (whose net-standard

# language code is pl) may wish to use "AddLanguage pl .po" to

# avoid the ambiguity with the common suffix for perl scripts.

#

# Note 2: The example entries below illustrate that in some cases

# the two character 'Language' abbreviation is not identical to

# the two character 'Country' code for its country,

# E.g. 'Danmark/dk' versus 'Danish/da'.

#

# Note 3: In the case of 'ltz' we violate the RFC by using a three char

# specifier. There is 'work in progress' to fix this and get

# the reference data for rfc1766 cleaned up.

#

# Specify a default charset for all content served; this enables

# interpretation of all content as UTF-8 by default.  To use the

# default browser choice (ISO-8859-1), or to allow the META tags

# in HTML content to override this choice, comment out this

# directive:

#

AddDefaultCharset UTF-8

#

# AddType allows you to add to or override the MIME configuration

# file mime.types for specific file types.

#

#AddType application/x-tar .tgz

#

# AddEncoding allows you to have certain browsers uncompress

# information on the fly. Note: Not all browsers support this.

# Despite the name similarity, the following Add* directives have nothing

# to do with the FancyIndexing customization directives above.

#

#AddEncoding x-compress .Z

#AddEncoding x-gzip .gz .tgz

# If the AddEncoding directives above are commented-out, then you

# probably should define those extensions to indicate media types:

#

AddType application/x-compress .Z

AddType application/x-gzip .gz .tgz

#

#   MIME-types for downloading Certificates and CRLs

#

AddType application/x-x509-ca-cert .crt

AddType application/x-pkcs7-crl    .crl

#

# AddHandler allows you to map certain file extensions to "handlers":

# actions unrelated to filetype. These can be either built into the server

# or added with the Action directive (see below)

#

# To use CGI scripts outside of ScriptAliased directories:

# (You will also need to add "ExecCGI" to the "Options" directive.)

#

#AddHandler cgi-script .cgi

#

# For files that include their own HTTP headers:

#

#AddHandler send-as-is asis

#

# For type maps (negotiated resources):

# (This is enabled by default to allow the Apache "It Worked" page

#  to be distributed in multiple languages.)

#

AddHandler type-map var

#

# Filters allow you to process content before it is sent to the client.

#

# To parse .shtml files for server-side includes (SSI):

# (You will also need to add "Includes" to the "Options" directive.)

#

AddType text/html .shtml

AddOutputFilter INCLUDES .shtml

#

# Action lets you define media types that will execute a script whenever

# a matching file is called. This eliminates the need for repeated URL

# pathnames for oft-used CGI file processors.

# Format: Action media/type /cgi-script/location

# Format: Action handler-name /cgi-script/location

#

#

# Customizable error responses come in three flavors:

# 1) plain text 2) local redirects 3) external redirects

#

# Some examples:

#ErrorDocument 500 "The server made a boo boo."

#ErrorDocument 404 /missing.html

#ErrorDocument 404 "/cgi-bin/missing_handler.pl"

#ErrorDocument 402 http://www.example.com/subscription_info.html

#

#

# Putting this all together, we can internationalize error responses.

#

# We use Alias to redirect any /error/HTTP_<error>.html.var response to

# our collection of by-error message multi-language collections.  We use

# includes to substitute the appropriate text.

#

# You can modify the messages' appearance without changing any of the

# default HTTP_<error>.html.var files by adding the line:

#

#   Alias /error/include/ "/your/include/path/"

#

# which allows you to create your own set of files by starting with the

# /var/www/error/include/ files and

# copying them to /your/include/path/, even on a per-VirtualHost basis.

#

Alias /error/ "/var/www/error/"

### Section 3: Virtual Hosts

#

# VirtualHost: If you want to maintain multiple domains/hostnames on your

# machine you can setup VirtualHost containers for them. Most configurations

# use only name-based virtual hosts so the server doesn't need to worry about

# IP addresses. This is indicated by the asterisks in the directives below.

#

# Please see the documentation at

# <URL:http://httpd.apache.org/docs/2.2/vhosts/>

# for further details before you try to setup virtual hosts.

#

# You may use the command line option '-S' to verify your virtual host

# configuration.

#

# Use name-based virtual hosting.

#

#NameVirtualHost *:80

#

# NOTE: NameVirtualHost cannot be used without a port specifier

# (e.g. :80) if mod_ssl is being used, due to the nature of the

# SSL protocol.

#

//虚拟主机配置

# VirtualHost example:

# Almost any Apache directive may go into a VirtualHost container.

# The first VirtualHost section is used for requests without a known

# server name.

#

#<VirtualHost *:80>

#    ServerAdmin webmaster@dummy-host.example.com

#    DocumentRoot /www/docs/dummy-host.example.com

#    ServerName dummy-host.example.com

#    ErrorLog logs/dummy-host.example.com-error_log

#    CustomLog logs/dummy-host.example.com-access_log common

#</VirtualHost>
