apache下设置域名多站点访问
当前系统：macOS High Sierra
域名访问配置指定端口后，不同域名只能配置不同的端口
apache配置目录：
sudo vim /etc/apache2/httpd.conf
sudo vim /etc/apache2/extra/httpd-vhosts.conf
具体代码如下(/etc/apache2/extra/httpd-vhosts.conf)：
Listen
<VirtualHost *:>
DocumentRoot "/Users/wanghaokun/dev/code/demo"
ServerName localhost
ErrorLog "/private/var/log/apache2/localhost-error_log"
CustomLog "/private/var/log/apache2/localhost-access_log" common
<Directory />
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order deny,allow
Allow from all
Require all granted
</Directory>
</VirtualHost> Listen
<VirtualHost *:>
DocumentRoot "/Users/wanghaokun/dev/code/phalcon54/"
ServerName www.testphalcon.com
ErrorLog "/private/var/log/apache2/testphalcon-error_log"
CustomLog "/private/var/log/apache2/testphalcon-access_log" common
<Directory />
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order deny,allow
Allow from all
Require all granted
</Directory>
</VirtualHost>
apache启动方式：
sudo apachectl start
sudo apachectl stop
sudo apachectl restart
禁止apache访问80端口
在apache配置目录中查找80端口占用情况，修改或注释对应代码段即可
