默认情况下，linux上apache使用的
默认文档目录是：/var/www
默认端口是：80
如果想发布自己的一个系统资源目录，可以使用下面的方法,执行如下命令：
(1)添加监听端口
#cd /etc/apache2
#vim ports.conf
文件添加：
NameVirtualHost *:8000
Listen 8000
(2)配置虚拟目录
#cd /etc/apache2/sites-available
#cp default default-me
#vim default-me
文件内容如下：
复制代码 代码如下:
<VirtualHost *:8000 >
    ServerAdmin webmaster@localhost
    DocumentRoot /wwwroot
    <Directory / >
Options FollowSymLinks
AllowOverride None
    </Directory>
    <Directory /wwwroot/ >
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
    </Directory>
    ErrorLog /var/log/apache2/error.log
    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn
    CustomLog /var/log/apache2/access.log combined
</VirtualHost>

粗体部分是关键点。
(3)发布站点
# ln -s /etc/apache2/sites-available/default-me /etc/apache2/sites-enabled/001-default
(4)重启服务
#/etc/init.d/apache2 restart
(5)测试
http://localhost:8000/
如果能够正常访问就说明配置正确了。

# Virtual Hosts
#
# 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.
#
# Use name-based virtual hosting.
#
NameVirtualHost *:81
NameVirtualHost *:82
NameVirtualHost *:83
NameVirtualHost *:84
NameVirtualHost *:85
NameVirtualHost *:86
#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
<VirtualHost *:81>

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
1、单域名单端口设置

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
复制代码 代码如下:
DocumentRoot "/srv/www/htdocs"
#
# Configure the DocumentRoot
#
<Directory "/srv/www/htdocs">
# 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
</Directory>

2、单域名多端口设置
复制代码 代码如下:
<Directory "/srv/www/htdocs/bbs">
    Options None
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
<Directory "/srv/www/htdocs/">
    Options None
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
NameVirtualHost   *:80
NameVirtualHost   *:81
<VirtualHost *:80>
  DirectoryIndex  index.html index.php
  ServerName   "www.abc.com "
  DocumentRoot   "/srv/www/htdocs/" 
  </VirtualHost>
<VirtualHost *:81>
  DirectoryIndex   index.php
    ServerName   "www.abc.com:81 "
  DocumentRoot   "/srv/www/htdocs/bbs/" 
  </VirtualHost>

3、多域名多端口设置
复制代码 代码如下:
<Directory "/srv/www/htdocs/btc">
    Options None
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
<Directory "/srv/www/htdocs/bbs">
    Options None
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
<Directory "/srv/www/htdocs/">
    Options None
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
NameVirtualHost   *:80
NameVirtualHost   *:81
<VirtualHost *:80>
  DirectoryIndex  index.html index.php
  ServerName   "www.abc.com "
  DocumentRoot   "/srv/www/htdocs/" 
  </VirtualHost>
<VirtualHost *:80>
  DirectoryIndex  index.html index.php
  ServerName   "www.btc.com "
  DocumentRoot   "/srv/www/htdocs/btc" 
  </VirtualHost>
<VirtualHost *:81>
  DirectoryIndex   index.php
    ServerName   "www.abc.com:81 "
  DocumentRoot   "/srv/www/htdocs/bbs/" 
  </VirtualHost>

需要注意的问题是，多端口监听，一定要注意listen.conf文件，是否开启了相应端口。
