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我的 Ubuntu 电脑上设置 Apache 虚拟主机。我创建了一个，no-ip domain我将使用它作为虚拟主机的主机名。我按照教程的每个步骤操作，但不起作用。这是虚拟主机文件，它名为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 [email protected]
        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，它如下所示：

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

crm2plus.ddns.net当我通过 chrome导航到 时，我发现web page not available page.shhasan.ddns.net工作正常。当我ssh-keygen -H -F crm2plus.ddns.net在终端中输入时，什么都没有显示，但是当我输入ssh-keygen -H -F shhasan.ddns.net以下内容时，就会显示以下内容：

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

接下来是 RSA 密钥。

我还查看了 Apache 错误和访问日志。错误日志中有很多重复的代码行：

[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

我搜索了一下caught SIGTERM, shutting down，发现这是正常操作的一部分。我不知道我哪里做错了。以前对 有用，shhasan.ddns.net但对 却不起作用crm2plus.ddns.net。

非常感谢所有的帮助和建议。

Answer 1

看起来第二个 .conf 文件尚未加载。可以通过包含Include path/to/conf_files/*.confconf/apache2.conf 并重新启动 apache 来解决。

请注意，访问crm2plus.ddns.net应记录在访问日志中。否则配置错误。

VirtualHosts 可以按如下方式配置。

1. 确保两个 FQDN 都指向 Apache2 服务器的 IP。可以通过 ping FQDN 来验证。
2. 实施小的改变并验证每个步骤的结果。

这个基本示例已经在apache2.conf中实现：

NameVirtualHost *:80

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/mydomain.com
    ServerName mydomain.com
    ErrorLog logs/mydomain.com-error_log
    CustomLog logs/mydomain.com-access_log common
</VirtualHost>
<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/myseconddomain.com
    ServerName myseconddomain.com
    ErrorLog logs/myseconddomain.com-error_log
    CustomLog logs/myseconddomain.com-access_log common
</VirtualHost>

mkdir /var/www/mydomain.com && echo helloworld > /var/www/mydomain.com/index.html

mkdir /var/www/myseconddomain.com && echo helloworld2 > /var/www/myseconddomain.com/index.html

并且它可以工作，即在服务重新启动后导航到mydomain.com显示helloworld并显示myseconddomain.com结果。helloworld2

建议从头开始，实现两个基本的 VirtualHost，以确保基本功能正常运作。实现后，可以进行其他更改。

虚拟主机定义略有修改的版本RiggsFolly 在 stackoverflow 上的回答为**工作crm2plus.ddns.net

<VirtualHost *:80>

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

        Options +Indexes +FollowSymLinks
        Order allow,deny

        AllowOverride All
    </Directory>


    # Possible values include: debug, info, notice, warn, error, crit,
