解决 apache2 .htacess 失效的问题

1、允许使用rewrite模块

#a2enmod rewrite

*会出现的问题：

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8",
LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to a fallback locale ("en_US.UTF-8").
Module rewrite already enabled

*解决方案：

安装 multipath-tools

#apt-get install multipath-tools

Generating locales
Missing locales are generated with locale-gen:

#locale-gen en_US.UTF-8

Alternatively, a locale file can be created manually with localedef:[1]

#localedef -i en_US -f UTF-8 en_US.UTF-8

Setting Locale Settings
The locale settings can be set (to en_US.UTF-8 in the example) as follows:

#export LANGUAGE=en_US.UTF-8
#export.UTF-8
#export LC_ALL=en_US.UTF-8
#locale-gen en_US.UTF-8
#dpkg-reconfigure locales

The dpkg-reconfigure locales command will open a dialog under Debian for selecting the desired locale. This dialog will not appear under Ubuntu. The Configure Locales in Ubuntu article shows how to find the information regarding Ubuntu.

2、创建.htpasswd文件：

http://www.luft.co.jp/cgi/htpasswd.php

*创建密码后，创建.htpasswd文件，输入创建后生成的秘文：

例如：admin:oGF.aXBiBIUTM    //ID为admin，密码为1111111 的密文

*创建密码文件后在.htacess文件中输入以下：

AuthType Basic
AuthName "Input your ID and Password."
AuthUserFile /var/www/html/.htpasswd
require valid-user

3、最终还是无法解析.htacess文件的原因：

*如果是直接使用的默认apache配置，则需改/etc/apache2/apache2.conf部分配置与以下一致即可：

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>

*主要是 AllowOverride All， 如果是AllowOverride Denny 则无法解析.htacess文件。
