linux - Apache 虚拟主机无法在 Ubuntu 14.04 LTS 上运行

Question

我一直在使用 this tutorial在我的 Ubuntu 电脑上设置 Apache 虚拟主机。我创建了一个 no-ip 域，我将使用它作为我的虚拟主机的主机名。我已经按照教程的每一步进行操作，但它不起作用。这是虚拟主机文件，它被命名为 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 和域名对添加到我的本地主机文件中，如下所示:

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 导航到 crm2plus.ddns.net 时，我得到了 web page not available page。 shhasan.ddns.net 运行良好。当我在终端中键入 ssh-keygen -H -F crm2plus.ddns.net 时，没有任何显示，但是当我键入 ssh-keygen -H -F shhasan.ddns.net 这是显示的内容:

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

后跟 RSA key 。

我还查看了 Apache 错误和访问日志。错误日志中有很多重复这样的代码行:

[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 我发现这是正常操作的一部分。我不知道我哪里出错了。它以前适用于 shhasan.ddns.net 但不适用于 crm2plus.ddns.net。

非常感谢所有帮助和建议。

您可以尝试在虚拟主机定义文件中使用 Apache2.4 语法进行访问控制，因为您使用的是 Apache2.4，那么如果您没有激活 mod_access_compat.so 它应该可以工作或者如果有，您可以将其停用。

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

我必须承认我更喜欢在 VH 定义本身中添加对虚拟主机的访问控制。然后你只需看一眼就知道实际发生了什么。所以你可以考虑这样做。

<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 httpd.conf 文件中乱用这个参数时要小心

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

这控制了 Apache 对根文件夹的访问权限，当然您不希望 Apache 或您的 Apache 上的黑客访问整个宇宙。

所以我建议你把这个改回

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

当然是再次使用 Apache2.4 语法。

更新:上述 VH 定义的略微编辑版本适用于 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>
