首先谈一点自己的理解
所谓虚拟主机，是说通过几个不同的url地址，都能到达nginx环境，只不过针对不同的url，处理的逻辑不同。
nginx支持虚拟主机，但是浏览器等客户端不知道，所以虚拟主机的几个地址，应该是都指向nginx所在的ip地址，虚拟主机功能才能正常。下面来说一下nginx环境下虚拟主机的配置
假设我们需要配置的虚拟主机域名为mail.zjc.com
虚拟主机存放目录为/var/www/mail.zjc.com/web sudo mkdir -p /var/www/mail.zjc.com/web
创建nginx虚拟主机配置文件 sudo gedit /etc/nginx/sites-available/mail.zjc.com.vhost
内容为(其中php域根据本机php应用情况配置)
<span>server</span> {
<span>listen</span><span>80</span>;
<span>server_name</span> mail.zjc.com;
<span>root</span> /var/www/mail.zjc.com/web;
<span>if</span> (<span>$http_host</span> != <span>"mail.zjc.com"</span>) {
<span>rewrite</span><span> ^</span><span>http://mail.zjc.com$request_uri</span><span>permanent</span>;
}
<span>index</span> index.php index.html;
<span>location</span> = /favicon.ico {
<span>log_not_found</span><span>off</span>;
<span>access_log</span><span>off</span>;
}
<span>location</span> = /robots.txt {
<span>allow</span> all;
<span>log_not_found</span><span>off</span>;
<span>access_log</span><span>off</span>;
}
<span># Make sure files with the following extensions do not get loaded by nginx because nginx would display the source code, and these files can contain PASSWORDS!</span><span>location</span><span>~* \.(engine|inc|info|install|make|module|profile|test|po|sh|.*sql|theme|tpl(\.php)?|xtmpl)$|^(\..*|Entries.*|Repository|Root|Tag|Template)$|\.php_</span> {
<span>deny</span> all;
}
<span># Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).</span><span>location</span><span>~ /\.</span> {
<span>deny</span> all;
<span>access_log</span><span>off</span>;
<span>log_not_found</span><span>off</span>;
}
<span>location</span><span>~* \.(jpg|jpeg|png|gif|css|js|ico)$</span> {
<span>expires</span> max;
<span>log_not_found</span><span>off</span>;
}
<span>location</span><span>~ \.php$</span> {
<span>try_files</span><span>$uri</span> =<span>404</span>;
<span>fastcgi_split_path_info</span><span> ^(.+\.php)(/.+)$</span>;
<span>fastcgi_pass</span><span>unix:/var/run/php5-fpm.sock</span>;
<span>fastcgi_index</span> index.php;
<span>fastcgi_param</span> SCRIPT_FILENAME <span>$document_root</span><span>$fastcgi_script_name</span>;
<span>include</span> fastcgi_params;
}
}因为nginx的主配置文件nginx.conf会自动应用sites-enabled中的配置文件，所以我们需要在sites-enabled中建立一个mail.zjc.com.vhost文件的链接
cd /etc/nginx/sites-enabled sudo ln -s /etc/nginx/sites-available/mail<span>.zjc</span><span>.com</span><span>.vhost</span> www<span>.zjc</span><span>.com</span><span>.vhost</span>
重新加载nginx使配置生效 sudo /etc/init.d/nginx reload
好了，接下来在/var/www/mail.zjc.com/web目录下创建一些文件（例如index.php）就可以通过http://mail.zjc.com/index.php来访问了。BTW，记得在hosts中或者DNS上设置mail.zjc.com指向nginx所在的IP地址。
