我安装了apache2。我已经将index.php文件添加到文档根目录，即/ srv / www / htdocs，当我在浏览器中给出http://localhost时，它提供了保存文件而不是显示文件的选项。
我的httpd.conf文件如下所示：
#
# /etc/apache2/httpd.conf
#
# 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 about
# the directives.

### Global Environment ######################################################
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests.
# run under this user/group id
Include /etc/apache2/uid.conf
# - how many server processes to start (server pool regulation)
# - usage of KeepAlive
Include /etc/apache2/server-tuning.conf
# 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
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.

### 'Main' server configuration #############################################
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition. 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.
#
Include /etc/apache2/default-server.conf
# Another way to include your own files
#
# The file below is generated from /etc/sysconfig/apache2,
# include arbitrary files as named in APACHE_CONF_INCLUDE_FILES and
# APACHE_CONF_INCLUDE_DIRS
Include /etc/apache2/sysconfig.d/include.conf
### Virtual server configuration ############################################
#
# VirtualHost: If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs-2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
Include /etc/apache2/vhosts.d/*.conf
# Note: instead of adding your own configuration here, consider
# adding it in your own file (/etc/apache2/httpd.conf.local)
# putting its name into APACHE_CONF_INCLUDE_FILES in
# /etc/sysconfig/apache2 -- this will make system updates
# easier :)
这是它在error_log中显示的内容：

我正在使用linux（suse）。 apache 2.2.8
答案 0 :(得分：1)
你安装了libapache2-mod-php5吗？
你启用了这个mod吗？
你有没有添加处理器的PHP文件？
<IfModule mod_php5.c>
<FilesMatch "\.ph(p3?|tml)$">
SetHandler application/x-httpd-php
</FilesMatch>
<FilesMatch "\.phps$">
SetHandler application/x-httpd-php-source
</FilesMatch>
# To re-enable php in user directories comment the following lines
# (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it
# prevents .htaccess files from disabling it.
<IfModule mod_userdir.c>
