# ServerName dummy-host.example.com
# ServerAlias www.dummy-host.example.com

# CustomLog "/private/var/log/apache2/dummy-host.example.com-access_log" common
#
#
# ServerAdmin [email protected]
# DocumentRoot "/usr/docs/dummy-host2.example.com"
# ServerName dummy-host2.example.com
# ErrorLog "/private/var/log/apache2/dummy-host2.example.com-error_log"
# CustomLog "/private/var/log/apache2/dummy-host2.example.com-access_log" common
#
7、添加下列配置，这里添加了 localhost 和 project.com 两个虚拟主机；"/Library/WebServer/Documents" 为默认目录，"/Users/mac168/sites" 为自定义目录。
DocumentRoot "/Library/WebServer/Documents"
ServerName localhost
ErrorLog "/private/var/log/apache2/localhost-error_log"
CustomLog "/private/var/log/apache2/localhost-access_log" common
DocumentRoot "~/sites"
ServerName project.com
ErrorLog "/private/var/log/apache2/sites-error_log"
CustomLog "/private/var/log/apache2/sites-access_log" common
Options Indexes FollowSymLinks MultiViews
AllowOverride none
Order deny,allow
Allow from all

9、修改为下列配置
127.0.0.1 localhost
127.0.0.1 project.com
255.255.255.255 broadcasthost
::1 localhost
::1 project.com
注意事项：
1、DocumentRoot 根目录如果没有 index 索引，访问 localhost 会提示 403 Forbidden。
2、自定义 DocumentRoot 根目录时，根目录的每一级都要有访问权限，否则同样提示 403 Forbidden。可通过 终端命令 chmod 修改，也可通过 command + i，显示目录简介，在 共享与权限 中修改（修改为 everyone 修改为 只读即可）。
