在Linux上使用Apache设置子域 [英] Setting up a subdomain with Apache on Linux

问题描述

我不敢相信我以前没有做过，但是我想要一个明确的答案，所以我已经准备好了.

I can't believe that I haven't done this before, but I would like a definitive answer so I'm all set going forward.

我在/etc/apache2/sites-available/mysite处有一个apache配置文件，如下所示:

I have an apache config file at /etc/apache2/sites-available/mysite which looks like this:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost

    DocumentRoot /home/sam/public_html
    <Directory />
            Options FollowSymLinks
            AllowOverride All
    </Directory>
    <Directory /home/sam/public_html>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride All
            Order allow,deny
            allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
            Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
            Order allow,deny
            Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

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

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

因此这可以很好地提供~/public_html中的html和php文件.但是我在那里有多个项目，因此想开始使用子域.我想做的是将~/public_html/myproject/中的文件作为myproject.localhost的根目录.

So this serves html and php files from ~/public_html all fine. But I have multiple projects there so would like to start using subdomains. What I want to do is serve files from ~/public_html/myproject/ as the root directory for myproject.localhost.

我尝试将以下内容添加到我的apache文件的底部:

I have tried adding the following to the bottom of my apache file:

<VirtualHost myproject.localhost>
    DocumentRoot ~/public_html/myproject/
    ServerName myproject.localhost
    ServerAdmin [e-mail]
    <Directory ~/public_html/myproject>
            Options Indexes FollowSymLinks
            AllowOverride FileInfo
            Order allow,deny
            Allow from all
    </Directory>
</VirtualHost>

但是apache抱怨:

but apache complains:

Restarting web server: apache2[Tue Aug 20 11:06:19 2013] [error] (EAI 2)Name or service not known: Could not resolve host name myproject.localhost -- ignoring!
 ... waiting [Tue Aug 20 11:06:20 2013] [error] (EAI 2)Name or service not known: Could not resolve host name myproject.localhost -- ignoring!

我知道我犯了一个基本错误，但是我不确定这是什么.

I know I'm committing a fundamental error, but I'm not sure what it is.

这是我现在的完整文件:

This is my complete file now:

<VirtualHost *:80>
    DocumentRoot /home/sam/public_html/ryua1226-magento/
    ServerName mydomain.localhost
    ServerAdmin [e-mail]
    <Directory /home/sam/public_html/ryua1226-magento>
            Options Indexes FollowSymLinks
            AllowOverride FileInfo
            Order allow,deny
            Allow from all
    </Directory>
</VirtualHost>


<VirtualHost *:80>
    ServerAdmin webmaster@localhost

    DocumentRoot /home/sam/public_html
    <Directory />
            Options FollowSymLinks
            AllowOverride All
    </Directory>
    <Directory /home/sam/public_html>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride All
            Order allow,deny
            allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
            Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
            Order allow,deny
            Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

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

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

推荐答案

您正在

You are telling Apache what IP and port you want to answer it on inside of the <VirtualHost> tag so here * means any IP, but accept requests for this site on port 80. Next you need to tell Apache where the document root is. ~/ means your default home directory, so if your DocumentRoot just happens to be the default home variable then it would work with your existing notation (depending on which user you're running the server as). Then you would declare the server name.

您要为其创建主机的每个域名都需要自己的虚拟主机指令，除非您使用别名.

Each domain name you're create a host for needs its own Virtual Host Directive unless you're using aliases.

<VirtualHost *:80>
    DocumentRoot /home/sam/public_html
    ServerName myproject.localhost

    # Other directives here

</VirtualHost>

<VirtualHost *:80>
    DocumentRoot /home/sam/public_html/myproject
    ServerName myotherproject.localhost

    # Other directives here

</VirtualHost>

关于主机 除此之外，您为主机创建的任何特殊名称都需要进入主机文件或DNS服务器中.这样，任何正在寻找您的服务器的Web浏览器都可以找到它，而无需键入IP.如果您尝试仅使用IP访问服务器，则可能会在设置中将多个主机置于同一IP上，因此，您只会获得第一个响应IP的主机(通常是vhosts列表中的顶部)

About Hosts In addition to this, any special name that you create for a host needs to go into a hosts file or in the DNS server as well. This way any web browser that is looking for your server can find it without having to type in the IP. Since you'll likely have multiple hosts on the same IP with your setup if you were to try and access the server with the IP only, you would only get the first host to respond on the IP (usually the top in the vhosts list).
