apache的httpd.conf翻译

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

这是Apache HTTP Server的主配置文件。它包括了

# configuration directives that give the server its instructions.

配置指令【directives】，这些指令给服务器服务器指令【instructions】【】

# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.

查看<URL:http://httpd.apache.org/docs/2.4/>以取得更多信息

# In particular, see

# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>

# for a discussion of each configuration directive.

特别指出，查看<URL:http://httpd.apache.org/docs/2.4/mod/directives.html>以得到关于每条配置命令的讨论

#

# 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.  

不要只是简单阅读这里的每条指令而不理解它们的所做所为【真实含义】。这里只是一种提示和提醒。如果你不能确定【它们的含义】，请参阅在线文档。特此警告！

#

# 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/access_log"

# with ServerRoot set to "/usr/local/apache2" will be interpreted by the

# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"

# will be interpreted as '/logs/access_log'.

#

关于配置文件和日志文件的名字：如果你使用了以斜杠“/“开始的指定了多个服务器控制文件名，那么服务器将使用那些绝对路径。

如 果你没有以斜杠“/“开始文件名，那么服务器根路径（ServerRoot）就是相对的---所以，像"logs/access_log"这样的服务器根 路径就将被服务器解释成加上"/usr/local/apache2"的"/usr/local/apache2/logs/access_log"，反 之"/logs/access_log"将被服务器解释成"/logs/access_log"

# NOTE: Where filenames are specified, you must use forward slashes

# instead of backslashes (e.g., "c:/apache" instead of "c:apache").

# If a drive letter is omitted, the drive on which httpd.exe is located

# will be used by default.  It is recommended that you always supply

# an explicit drive letter in absolute paths to avoid confusion.

注意：在文件名被指定的地方，你必须用“前斜杠”【就是我们平时说的斜杠"/"，与问号在同一个键，右手小指下的那个】代替后斜杠【即“反斜杠/】”（如：用"c:/apache"来代替"c:apache"）。

如果你省略了驱动器符号，那么httpd.exe将使用默认的驱动器。建议你总是在绝对路径中使用一个明确的驱动器符号，以避免混淆。

#

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

# configuration, error, and log files are kept.

ServerRoot：目录树的顶级根目录，用来保存服务器配置、错误、日志文件

#

# Do not add a slash at the end of the directory path.  If you point

# ServerRoot at a non-local disk, be sure to specify a local disk on the

# Mutex directive, if file-based mutexes are used.  If you wish to share the

# same ServerRoot for multiple httpd daemons, you will need to change at

# least PidFile.

不要在路径的最后加斜杠“/“。如果你指定的ServerRoot不是本地磁盘，要确定用互斥指令【Mutex directive】指定一个本地磁盘，如果基于文件的互斥指令被使用【？】。

如果你希望共享在多个httpd守护进程【daemons】中共享相同的ServerRoot，你至少需要修改PidFile【？】

#【下面这个命令是指定服务器根目录】

ServerRoot "c:/Apache24"

#

# Mutex: Allows you to set the mutex mechanism and mutex file directory

# for individual mutexes, or change the global defaults

互斥：允许你为多个不同的互斥对象设置互斥机制【mutex mechanism】和互斥文件目录，或者修改全局默认值

#

# Uncomment and change the directory if mutexes are file-based and the default

# mutex file directory is not on a local disk or is not appropriate for some

# other reason.

如果互斥对象是基于文件的以及默认的互斥文件目录不在本地磁盘或因为其它原因而不适用，那么取消注释并改变目录。

#【下面这个命令是改变互斥对象的目录】

# Mutex default:logs

#

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

# ports, instead of the default. See also the <VirtualHost>

# directive.

侦听：允许你绑定Apache服务器到指定ip地址和/或端口，用来代替默认值。参见<VirtualHost>指令。

#

# Change this to Listen on specific IP addresses as shown below to

# prevent Apache from glomming onto all bound IP addresses.

修改这个指令以侦听下面指定的ip地址，避免Apache服务器抓取全部绑定的IP地址

#【下面这个指令是80端口的IP地址，主网站IP就在这里配置】

#Listen 12.34.56.78:80

Listen 80

#

# Dynamic Shared Object (DSO) Support 动态共享对象支持

#

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

# have to place corresponding `LoadModule' lines at this location so the

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

# Statically compiled modules (those listed by `httpd -l') do not need

# to be loaded here.

为了能够使用一个作为DSO创建的模块【modules】的功能，你需要放置相应的【corresponding】`LoadModule'行在这个位置，这样在你使用之前，这些指令就包含在模块中了。
