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服務器配置文件。# 它給服務器指示配置指令。# 可去http://httpd.apache.org/docs/2.2/查看詳細信息# 特別情況可去http://httpd.apache.org/docs/2.2/mod/directives.html# 對每個配置指示進行討論     # 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。這里只是一點提醒信息。# # 配置指示分為三個基本組：# 1. 全局控制Apache操作指示。# 2. 'main'或者'default'服務器參數定義，#  這些參數響應非虛擬主機的操作請求。同時也為所以虛擬主機提供了默認設定值。# 3. 設置虛擬主機，可以通過一個Apache服務器來實現處理不同IP或者主機名的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，來指定服務器的控制文件名，服務器將使用顯式路徑。# 如果未用“/”開頭，比如文件名“logs/foo.log”，假設服務器根目錄為“/etc/httpd”，# 則，服務器會將它解釋為“/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1：全局環境# 這節的指令影響Apache的整體操作，比如它能操作的當前連接請求數目或者去哪里# 查找其配置文件等。   # Don't give away too much information about all the subcomponents# we are running. Comment out this line if you don't mind remote sites# finding out what major optional modules you are runningServerTokens OS # 不要泄漏太多的服務器信息。# 如果不想讓遠程站點了解到你的主要選型模塊信息，可以注釋掉該行。     # 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"     # 服務器的根：目錄樹的頂部，其下存放著配置、錯誤，以及日志文件等。## 注意！如果你打算將它放到掛載文件系統的NFS（或者其他網絡），建議參閱LockFile文檔# （有效鏈接為http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile）# 你將省去不少麻煩。# # 不要在目錄的末尾加斜線“/”# ServerRoot "/etc/httpd"     # PidFile: The file in which the server should record its process# identification number when it starts.#PidFile run/httpd.pid # Pid文件：當進程啟動時，服務器應當在其中記錄PID。# PidFile run/httpd.pid   ## Timeout: The number of seconds before receives and sends time out.#Timeout 120 # Timeout：確定發送超時和接收超時的秒數。Timeout 120   ## KeepAlive: Whether or not to allow persistent connections (more than# one request per connection). Set to "Off" to deactivate.#KeepAlive Off # KeepAlive：是否允許保持連接狀態（每次連接可以執行多個請求）。一般設置為“Off”。KeepAlive Off     ## 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   # MaxKeepAliveRequests：持續連接最大數。0表示無限數量。# 為了最大性能，推薦將其設置高一點。MaxKeepAliveRequests 100   ## KeepAliveTimeout: Number of seconds to wait for the next request from the# same client on the same connection.#KeepAliveTimeout 15 # KeepAliveTimeout：同一客戶端同一連接請求的間隔秒數。KeepAliveTimeout 15   #### Server-Pool Size Regulation (MPM specific)## ## 服務器池大小調整（MPM 特性）     # 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    8MinSpareServers  5MaxSpareServers  20ServerLimit   256MaxClients    256MaxRequestsPerChild 4000</IfModule>     # prefork MPM（預分離多進程模塊）# StartServices：服務器啟動進程數# MinSpareServers：最小空閑進程數# MaxSpareServers：最大空閑進程數# ServerLimit：最大進程數MaxClients時，服務器的最大生存時間值# MaxClients：服務器運行啟動的最大進程數量# MaxRequestPerChild：每個服務子進程的最大請求數量<IfModule prefork.c>StartServers    8MinSpareServers  5MaxSpareServers  20ServerLimit   256MaxClients    256MaxRequestsPerChild 4000</IfModule>       # 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     2MaxClients     150MinSpareThreads   25MaxSpareThreads   75ThreadsPerChild   25MaxRequestsPerChild 0</IfModule>     # worker 多進程模塊# StartServers：服務器啟動進程的初始化數目# MaxClients：同時客戶端連接的最大數目# MinSpareThreads：最小空閑worker線程數# MaxSpareThreads：最大空閑worker線程數# ThreadsPerChild：每個服務器子進程的worker線程數# MaxRequestsPerChild：每個子進程的最大請求數<IfModule worker.c>StartServers     2MaxClients     150MinSpareThreads   25MaxSpareThreads   75ThreadsPerChild   25MaxRequestsPerChild 0</IfModule>       ## Listen: Allows you to bind Apache to specific IP addresses and/or# ports, in addition to the default.

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.#     ### 章節2：‘Main'服務器配置# # 該章節設置‘Main'服務器使用的指令，響應所有非<VirtualHost>定義的請求。# 這些指令值也為<VirtualHost>部分提供默認值。# # 所有這些指令都可以在<VirtualHost>段中出現，此時，這些默認值將被虛擬主機的相關設置值所覆蓋。       ## 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#ServerAdmin root@localhost   # ServerAdmin：服務器管理員的郵箱地址，該地址一般出現在服務器生成頁中，比如錯誤文檔等。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     # ServerName 給出一個服務器用來標識它自己的名稱和端口。# 通常被自動指定，但為避免啟動時的問題，推薦明確指定它。# # 如果主機沒有設置有效的DNS名稱，server-generated指令將不會工作。# # 如果主機沒有注冊DNS，輸入其IP地址。這樣就可以通過IP地址訪問你的主機了。# #ServerName www.example.com:80       ## 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   # UseCanonicalName：確定apache如何構建自引用URLs和SERVER_NAME、SERVER_PORT變量。# 當設為Off時，apache將使用客戶端支持的Hostname和Port。當設為On時，apache將使用# ServerName指令值。#UseCanonicalName Off     ## 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"   # DocumentRoot：提供文檔的根目錄。# 默認，所有請求都由該目錄提供，但是可以用連接符和別名指向其他位置。# DocumentRoot “/var/www/html”     ## 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.#<Directory />  Options FollowSymLinks  AllowOverride None</Directory>     # 每個apache存取的目錄（包括子目錄）都可配置為允許和禁止。# # 首先，我們配置嚴格特征集合的默認值。# <Directory />  Options FollowSymLinks  AllowOverride None</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.#   # 注意，從此點開始，必須指定使能特殊特性的允許。所以，如果一些事情沒有安裝你的期望的運行，# 確保你已經指定并使能以下特性。   ## This should be changed to whatever you set DocumentRoot to.#<Directory "/var/www/html"> # 這里應當根據你設定的DocumentRoot值進行修改。<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.

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：在此添加無限個你需要的別名。# 格式為 Alias 別名 真名# 注意，如果別名中以“/”結尾，則服務器將要求“/”出現在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.

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在你空間中使用的文檔已經不存在了。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.
