编辑：我很确定我的 .htaccess 文件没有被执行，问题不在于我的重写规则。
我一直没能用 mod_rewrite 让 .htaccess 正常工作。基本上，我所做的就是从“http://www.site.com“ 和 ”https://www.site.com“。
如果我遗漏了什么（conf 文件等，请告诉我，我会更新它）
我只是看不出这里有什么问题...我正在使用 1&1 VPS III 虚拟专用服务器...有人遇到过这个问题吗？
我正在使用 Ubuntu 8.04 Server LTS。
这是我的 .htaccess 文件（位于 @ /var/www/site/trunk/html/）

我的 Apache 配置文件：
apache2.conf
#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# 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 "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/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.
#
#
# 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-2.1/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.
#

# identification number when it starts.

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

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#

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

# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are

#
# HostnameLookups: Log the names of clients or just their IP addresses

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be

# ServerTokens
# This directive configures what you return as the Server HTTP response
# Header. The default is 'Full' which sends information about the OS-Type
# and compiled in modules.
# Set to one of: Full | OS | Minor | Minimal | Major | Prod
# where Full conveys the most information, and Prod the least.
#
ServerTokens Full
#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory

#
# 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
# /usr/share/apache2/error/include/ files and copying them to /your/include/path/,
# even on a per-VirtualHost basis. The default include files will display
# your Apache version number and your ServerAdmin email address regardless
# of the setting of ServerSignature.
#
# The internationalized error documents require mod_alias, mod_include
# and mod_negotiation. To activate them, uncomment the following 30 lines.
# Alias /error/ "/usr/share/apache2/error/"

答案1
尝试将重写规则直接放入 VirtualHost 配置部分（而不是“目录”规则下）
这样，您可以绕过可能由 .htaccess 和路径识别机制引起的任何问题。
检查rewrite_module是否已加载到apache中：
apache2ctl -t -D DUMP_MODULES
如果未启用，请使用以下命令启用 mod_rewrite
a2enmod rewrite
这将在 mods 下设置必要的链接-已启用（不是模组-可用的）
答案2
root@s15348441：/etc/apache2/mods-available#更多rewrite.load LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so
检查它/etc/apache2/mods-enabled是否确实被拉入 Apache 配置。我怀疑重写模块根本没有被加载（尽管我本来希望在日志中看到有关它的错误）。
答案3
基于 Debian 的发行版（例如 Ubuntu）将其称为 apache，而不是 httpd。
答案4
您是否检查过您的群组和用户权限？
如果您使用：
ls -lah <path to file>
它将给你如下输出：
-rw-r--r-- 1 <group> <user> 7.5K Jun 7 22:49 <path to file>
如果不正确，只需使用
chown <user>:<group> <path to file>
