Mac apachec 将域名映射到指定目录

我配置的服务器根目录下有两个文件，一个学习用的thinkPHP5,一个是之前自学时敲的一些小demo.我一直想通过域名来访问服务器，也可以用域名来访问服务器指定目录下的文件。文件结构如下，sites是我的根目录,我想通过www.lrg.com来访问sites,通过www.tp5.com 来访问 sites/tp5/public,通过www.phplearn.com来访问sites/PHPLearn/,效果图如下：

完成效果图，下面就是配置过程。

/private/etc/apache2/extra/httpd-vhosts.conf
找到这个文件配置虚拟主机，可以用vim编辑，也可以用文本编辑器打开，拖出来，编辑好，拷贝再粘贴到上层文件夹，输下密码就可以了。

# Virtual Hosts
#
# Required modules: mod_log_config

# 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/2.4/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.

#
# 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 *:80>  
        ServerAdmin 1051099153@qq.com  
        ServerName localhost.com     
        ServerAlias localhost.com    
        DocumentRoot "/Users/LRG/sites/" 
</VirtualHost> 


<VirtualHost *:80>
    ServerAdmin 1051099153@qq.com
    ServerName  www.lrg.com
    ServerAlias www.lrg.com 
    DocumentRoot "/Users/LRG/sites/"
</VirtualHost>

<VirtualHost *:80>
    ServerAdmin 1051099153@qq.com
    ServerName  www.phplearn.com
    ServerAlias www.phplearn.com
    DocumentRoot "/Users/LRG/sites/PHPLearn/"
</VirtualHost>

<VirtualHost *:80>
    ServerAdmin 105109913@qq.com
    ServerName  www.tp5.com
    ServerAlias www.tp5.com
    DocumentRoot "/Users/LRG/sites/tp5/public/"
</VirtualHost>

问题：其实我早就应该装好了，但是呢，我中途出了点问题，可以用这个命令检查你的apachectl配置有没有出错
apachectl configtest

我碰到的问题：1、填的网易邮箱，可能是邮箱里面有下划线，报错。
                           2、DocumentRoot那一行有两个引号，第一个是英文字母，第二个却是汉子的双引号，用上面的命令一查，就知道错哪了。

配置好这个文件后，需要配置这个文件，将主机ip映射到对应域名：

/private/etc/hosts

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       www.lrg.com
255.255.255.255 broadcasthost
127.0.0.1       localhost 
127.0.0.1       www.phplearn.com
127.0.0.1       www.tp5.com

修改后，用configtest检查一下配置，没问题，重启一下apache,就大公告成

sudo apachectl start
sudo apachectl restart
sudo apachectl stop
