If you look at <code>nginx.conf</code>, you will find <a href="http://nginx.org/r/include"><code>include</code></a> directive that includes all files from the <code>sites-enabled</code> directory. This directory stores symlinks to config files from <code>sites-available</code> in order to be convenient to switch on and off parts of your configuration.

As you can see, there's no magic with these directories.

If you want to host multiple websites you should use multiple <a href="http://nginx.org/r/server"><code>server</code></a> blocks and/or <a href="http://nginx.org/r/server_name"><code>server_name</code></a> directive. Official tutorials are here: <a href="http://nginx.org/en/docs/http/server_names.html">Server names</a> and <a href="http://nginx.org/en/docs/http/request_processing.html">How nginx processes a request</a>.

blocks|key|295935|text|为了添加另一种方法，您可以为您托管的每个虚拟域或站点使用一个单独的文件。您可以使用default的副本作为每个站点的起点，并为每个站点进行自定义。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|295936|然后在启用的站点中创建符号链接。通过这种方式，您只需添加或删除symlink并发出service+nginx+reload即可打开和关闭站点。|295937|在进行站点维护时，您可以更有创意地使用此方法将站点重定向到维护模式页面。|295938|所以它的结构是这样的：|295939|/sites-available/+(you+can+use+obvious+file+names+like+this)
%7C+
%7C->+a.mysite.com
%7C->+b.mysite.com
%7C->+someOtherSite.com

%7C+
%7C->+a.mysite.com
%7C->+b.mysite.com|code-block|syntax|javascript|295940|注意，由于只有前两个条目是sites-enabled中唯一的符号链接项，因此第三个条目someOtherSite.com处于离线状态。|offset|length|style|CODE|295941|entityMap^0|0|0|0|0|0|D|D|17|H|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|W|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|X|8|@]|9|@]|A|$]]|$1|H|3|I|5|J|7|Y|8|@]|9|@]|A|$K|L]]|$1|M|3|N|5|6|7|Z|8|@$O|10|P|11|Q|R]|$O|12|P|13|Q|R]]|9|@]|A|$]]|$1|S|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|T|$]]

Just to add another approach, you can use a separate file for each virtual domain or site you're hosting.
You can use a copy of default as a starting point for each one and customize for each site. 
Then create symlinks in sites-enabled. In this way you can take sites up and down just by adding or removing a symlink and issuing a service nginx reload. 

You can get creative and use this method to redirect sites to a maintenance mode page while you are doing site maintenance.

So the structure looks like this:

<pre><code>/sites-available/ (you can use obvious file names like this)
| 
|-&gt; a.mysite.com
|-&gt; b.mysite.com
|-&gt; someOtherSite.com

/sites-enabled/ (these are just symlinks to the real files in /sites-available)
| 
|-&gt; a.mysite.com
|-&gt; b.mysite.com
</code></pre>

Notice that since there are only the first two entries are the only symlinked items in <code>sites-enabled</code>, the third entry, <code>someOtherSite.com</code> is therefore offline.

You symlink the default file from sites available to sites enabled. Then you modify the available site to include two server blocks each with a different server_name. see the following. This assumes you have to domains called example.com and example2.com. You would also have pointed your @records to the ip address of the server where you've installed nginx. 

symlink the available site to an enabled site

<pre><code>sudo ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default
</code></pre>

edit the file using your editor of choice (vim for me)

<pre><code>sudo vi /etc/nginx/sites-available/default
</code></pre>

Here's contents of working nginx conf, assuming you are running web apps on the port 4567 and 4568.

<pre><code>server {

 server_name www.example.com

 location / {
 proxy_pass http://localhost:4567/;
 }

}


server {

 server_name www.example2.com

 location {
 proxy_pass http://localhost:4568/;
 }

}
</code></pre>

With the base install of nginx, your <code>sites-available</code> folder has just one file: <code>default</code>

how does the <code>sites-available</code> folder work and how would I use it to host multiple (separate) websites?

multiple websites on nginx & sites-available

对于nginx的基本安装，您的sites-available文件夹只有一个文件：defaultsites-available文件夹是如何工作的，我如何使用它来托管多个(独立的)网站？
