apache 2.2

# 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.   # 這是主Apache服務(wù)器配置文件。# 它給服務(wù)器指示配置指令。# 可去http://httpd.apache.org/docs/2.2/查看詳細(xì)信息# 特別情況可去http://httpd.apache.org/docs/2.2/mod/directives.html# 對每個(gè)配置指示進(jìn)行討論     # 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.     # 要明白這些指令是做什么的。這里只是一點(diǎn)提醒信息。# # 配置指示分為三個(gè)基本組：# 1. 全局控制Apache操作指示。# 2. 'main'或者'default'服務(wù)器參數(shù)定義，#  這些參數(shù)響應(yīng)非虛擬主機(jī)的操作請求。同時(shí)也為所以虛擬主機(jī)提供了默認(rèn)設(shè)定值。# 3. 設(shè)置虛擬主機(jī)，可以通過一個(gè)Apache服務(wù)器來實(shí)現(xiàn)處理不同IP或者主機(jī)名的Web請求。       # 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".   # 配置名和日志文件名：# 如果用“/”或者Win32的“drive:/”開頭，來指定服務(wù)器的控制文件名，服務(wù)器將使用顯式路徑。# 如果未用“/”開頭，比如文件名“l(fā)ogs/foo.log”，假設(shè)服務(wù)器根目錄為“/etc/httpd”，# 則，服務(wù)器會(huì)將它解釋為“/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. ### 章節(jié)1：全局環(huán)境# 這節(jié)的指令影響Apache的整體操作，比如它能操作的當(dāng)前連接請求數(shù)目或者去哪里# 查找其配置文件等。   # Don't give away too much information about all the subcomponents# we are running.

If you *do* define an error logfile for a <VirtualHost># container, that host's errors will be logged there and not here.#ErrorLog logs/error_log   # ErrorLog：錯(cuò)誤日志文件的位置。# 如果不在<VirtualHost>段中指定錯(cuò)誤日志指令，虛擬主機(jī)的錯(cuò)誤日志信息也會(huì)記錄到這個(gè)文件。# 如果在<VirtualHost>段中指定錯(cuò)誤日志指令，則此虛擬主機(jī)的錯(cuò)誤將會(huì)在那里記錄而不在該文件記錄。# ErrorLog logs/error_log     ## LogLevel: Control the number of messages logged to the error_log.# Possible values include: debug, info, notice, warn, error, crit,# alert, emerg.#LogLevel warn   # LogLevel：控制什么級(jí)別的信息被記錄到error_log日志文件中。# 可能的值包括：debug，info，notice，warn，error，crit，alert，emerg。# LogLevel warn     ## The following directives define some format nicknames for use with# a CustomLog directive (see below).#LogFormat "%h %l %u %t /"%r/" %>s %b /"%{Referer}i/" /"%{User-Agent}i/"" combinedLogFormat "%h %l %u %t /"%r/" %>s %b" commonLogFormat "%{Referer}i -> %U" refererLogFormat "%{User-agent}i" agent # "combinedio" includes actual counts of actual bytes received (%I) and sent (%O); this# requires the mod_logio module to be loaded.#LogFormat "%h %l %u %t /"%r/" %>s %b /"%{Referer}i/" /"%{User-Agent}i/" %I %O" combinedio   # 下面的指令，為CustomLog指令定義了一些昵稱。# “combinedio”包含實(shí)際接收和發(fā)送字節(jié)的實(shí)際計(jì)數(shù)；這需要加載mod_logio模塊。     ## The location and format of the access logfile (Common Logfile Format).# If you do not define any access logfiles within a <VirtualHost># container, they will be logged here. Contrariwise, if you *do*# define per-<VirtualHost> access logfiles, transactions will be# logged therein and *not* in this file.##CustomLog logs/access_log common   # 普通日志文件的位置和格式。# 若在<VirtualHost>段中定義該指令，則其普通日志文件不會(huì)存在該文件中。# #CustomLog logs/access_log common     ## If you would like to have separate agent and referer logfiles, uncomment# the following directives.##CustomLog logs/referer_log referer#CustomLog logs/agent_log agent   # 若是想分離代理和引用日志文件，則取消下面指令的注釋。# #CustomLog logs/referer_log referer#CustomLog logs/agent_log agent   ## For a single logfile with access, agent, and referer information# (Combined Logfile Format), use the following directive:#CustomLog logs/access_log combined # 若是不想用分離代理和引用日志文件，則用下面的指令：# CustomLog logs/access_log combined     ## Optionally add a line containing the server version and virtual host# name to server-generated pages (internal error documents, FTP directory# listings, mod_status and mod_info output etc., but not CGI generated# documents or custom error documents).# Set to "EMail" to also include a mailto: link to the ServerAdmin.# Set to one of: On | Off | EMail#ServerSignature On     # 可選地添加一行包含服務(wù)器版本和虛擬主機(jī)名稱信息到服務(wù)器生成的頁中（內(nèi)部錯(cuò)誤文檔、FTP目錄列表、mod_status和# mod_info輸出等，但非CGI生成文檔或者自定義錯(cuò)誤文檔）。# 設(shè)置為“EMail”也包含mailto管理員郵箱的鏈接。# 可設(shè)置為其中之一： On | Off | EMail# ServerSignature On       ## Aliases: Add here as many aliases as you need (with no limit). The format is# Alias fakename realname## Note that if you include a trailing / on fakename then the server will# require it to be present in the URL. So "/icons" isn't aliased in this# example, only "/icons/". If the fakename is slash-terminated, then the# realname must also be slash terminated, and if the fakename omits the# trailing slash, the realname must also omit it.## We include the /icons/ alias for FancyIndexed directory listings. If you# do not use FancyIndexing, you may comment this out.#Alias /icons/ "/var/www/icons/" <Directory "/var/www/icons">  Options Indexes MultiViews  AllowOverride None  Order allow,deny  Allow from all</Directory>   # Aliases：在此添加無限個(gè)你需要的別名。# 格式為 Alias 別名 真名# 注意，如果別名中以“/”結(jié)尾，則服務(wù)器將要求“/”出現(xiàn)在URL中。# 別名中有“/”，則真名中必須有“/”。反之亦然。#     ## WebDAV module configuration section.#<IfModule mod_dav_fs.c>  # Location of the WebDAV lock database.  DAVLockDB /var/lib/dav/lockdb</IfModule>   # WebDAV模塊配置部分。# WebDAV鎖定數(shù)據(jù)庫的位置設(shè)置。     ## ScriptAlias: This controls which directories contain server scripts.# ScriptAliases are essentially the same as Aliases, except that# documents in the realname directory are treated as applications and# run by the server when requested rather than as documents sent to the client.# The same rules about trailing "/" apply to ScriptAlias directives as to# Alias.#ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"   # ScriptAlias：服務(wù)器腳本目錄別名。# 腳本目錄存放服務(wù)器響應(yīng)請求時(shí)執(zhí)行的應(yīng)用程序，而非發(fā)送給客戶端的文件。# “/”的處理跟Alias相同。# ScriptAlias /cgi-bin/ “/var/www/cgi-bin/”     ## "/var/www/cgi-bin" should be changed to whatever your ScriptAliased# CGI directory exists, if you have that configured.#<Directory "/var/www/cgi-bin">  AllowOverride None  Options None  Order allow,deny  Allow from all</Directory>   # “/var/www/cgi-bin”應(yīng)當(dāng)對應(yīng)到你自己的CGI路徑，如果你需要該配置。     ## Redirect allows you to tell clients about documents which used to exist in# your server's namespace, but do not anymore. This allows you to tell the# clients where to look for the relocated document.# Example:# Redirect permanent /foo http://www.example.com/bar   # 重定向允許你告訴客戶端曾經(jīng)在你空間中使用的文檔已經(jīng)不存在了。通知客戶端去什么位置查找文檔。   ## Directives controlling the display of server-generated directory listings.# ## 服務(wù)器生成路徑列表顯示的控制指令#   ## IndexOptions: Controls the appearance of server-generated directory# listings.#IndexOptions FancyIndexing VersionSort NameWidth=* HTMLTable # IndexOptions：服務(wù)器生成目錄列表的索引控制。IndexOptions FancyIndexing VersionSort NameWidth=* HTMLTable     ## AddIcon* directives tell the server which icon to show for different# files or filename extensions.
