apache 多端口

1、新建配置文件

touch /etc/apache2/sites-available/packages.conf

2、编辑配置文件(/etc/apache2/sites-available/packages.conf)

Listen 81

<VirtualHost *:81>
    ServerAdmin webmaster@localhost

    DocumentRoot /mnt/ramdisk
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </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>

3、链接

ln -s /etc/apache2/sites-available/packages.conf /etc/apache2/sites-enabled

4、在apache配置文件中（/etc/apache2/apache2.conf），添加如下内容：

<Directory /mnt>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

4、重启apache服务

service apache2 restart
