1、单域名单端口设置 如：www.abc.com 默认用80访问 特别说明，apache的配置默认都在安装目录下的conf目录里面 或者是/etc/apache2 不过一定要注意，listen.conf文件中端口监听是否开启 如下图，表示已经开启80端口监听
直接默认修改default-server.conf
这个配置最好简单
安装好了，之后，默认已经能够使用了，只是要把它修改成你需要的域名及访问路径罢了。
给一个标准配置吧
DocumentRoot "/srv/www/htdocs"
## Configure the DocumentRoot
#
# 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. Please see
# http://httpd.apache.org/docs-2.2/mod/core.html#options
# for more information.
Options None
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
AllowOverride None
# Controls who can get stuff from this server.
Order allow,deny
Allow from all
Options None
AllowOverride None
Order allow,deny

NameVirtualHost *:81
DirectoryIndex index.html index.PHP
ServerName "www.abc.com"
DocumentRoot "/srv/www/htdocs/"
DirectoryIndex index.php
ServerName "www.abc.com:81"
DocumentRoot "/srv/www/htdocs/bbs/"
3、多域名多端口设置
Options None
AllowOverride None
Order allow,deny
