Apache虚拟主机无法在Ubuntu 14.04 LTS上运行

Question

我一直在使用本教程在Ubuntu PC上设置Apache虚拟主机。 我已经创建了一个no-ip domain ，它将用作我的虚拟主机的主机名。 我已经按照本教程的每个步骤进行了操作，但是没有用。 这是虚拟主机文件，名为crm2plus.ddns.net.conf ：

<VirtualHost *:80>

        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@crm2plus.ddns.net
        ServerName  crm2plus.ddns.net
        ServerAlias crm2plus.ddns.net
        DocumentRoot /var/www/crm2plus.ddns.net/public_html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>
<Directory />
    Options FollowSymLinks
    AllowOverride All
</Directory>
<Directory /var/www>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order Allow,Deny
    Allow from all
</Directory>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

我还将ip和域名对添加到了本地主机文件中，它的外观如下：

23.253.21.201   shhasan.ddns.net
127.0.1.1       Ubuntu-Dev
127.0.0.1       localhost
99.250.71.177   crm2plus.ddns.net

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

当我通过chrome浏览到crm2plus.ddns.net ，我得到的web page not available page 。 shhasan.ddns.net运行正常。 当我在终端中输入ssh-keygen -H -F crm2plus.ddns.net ，没有任何显示，但是当我键入ssh-keygen -H -F shhasan.ddns.net ，显示的是：

# Host shhasan.ddns.net found: line 14 type RSA

其次是RSA密钥。

我还查看了Apache错误和访问日志。 错误日志中有很多这样的代码行重复：

[Fri Nov 14 17:44:50.304782 2014] [mpm_prefork:notice] [pid 21927] AH00163: Apache/2.4.7 (Ubuntu) PHP/5.5.9-1ubuntu4.5 configured -- resuming normal operations
[Fri Nov 14 17:44:50.304801 2014] [core:notice] [pid 21927] AH00094: Command line: '/usr/sbin/apache2'
[Fri Nov 14 17:44:54.979832 2014] [mpm_prefork:notice] [pid 21927] AH00169: caught SIGTERM, shutting down

我搜索了caught SIGTERM, shutting down然后发现这是正常操作的一部分。 我不知道我要去哪里错了。 它以前在shhasan.ddns.net上shhasan.ddns.net但在crm2plus.ddns.net 。

非常感谢所有帮助和建议。

您可以像使用Apache2.4一样尝试在虚拟主机定义文件中使用Apache2.4语法进行访问控制，然后，如果尚未激活mod_access_compat.so它应该可以工作，或者可以停用它。

<Directory /var/www>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Require all granted
</Directory>

我必须承认，我更喜欢在VH定义本身内为虚拟主机添加访问控制。 然后，您只要看一下实际发生的情况即可。 因此，您可以考虑这样做。

<VirtualHost *:80>
    ServerAdmin webmaster@crm2plus.ddns.net
    ServerName  crm2plus.ddns.net
    ServerAlias www.crm2plus.ddns.net
    DocumentRoot /var/www/crm2plus.ddns.net/public_html

    <Directory /var/www/crm2plus.ddns.net/public_html>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

另外，在使用httpd.conf文件中的此参数时，您应该小心

<Directory />
    Options FollowSymLinks
    AllowOverride All
#    Order deny,allow
#    Deny from all
</Directory>

这样可以控制Apache对根文件夹的访问，当然，您也不想允许Apache或Apache上的黑客访问Universe。

所以我建议您将其设置为

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Require all denied
</Directory>

当然，再次使用Apache2.4语法。

更新：上面的VH定义的略作编辑的版本适用于crm2plus.ddns.net

<VirtualHost *:80>

    ServerName crm2plus.ddns.net
        ServerAlias crm2plus.ddns.net
    ServerRoot /var/www/crm2plus.ddns.net/
    DocumentRoot /var/www/crm2plus.ddns.net/public_html

    <Directory "/var/www/crm2plus.ddns.net/public_html">
        Options +Indexes +FollowSymLinks
        Order allow,deny
        Allow from all
        AllowOverride All
    </Directory>


    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    ErrorLog ${APACHE_LOG_DIR}/crm2plus.ddns.net_error.log
    CustomLog ${APACHE_LOG_DIR}/crm2plus.ddns.net_access.log combined


</VirtualHost>

检查您的/etc/nsswitch.conf文件。 在我的Ubuntu 14.04LTS上，我必须更改行：

hosts:          files mdns4_minimal [NOTFOUND=return] dns

至：

hosts:          dns files mdns4_minimal [NOTFOUND=return]

为了使虚拟主机工作。
