nginx configure virtual host vhost

First talk about my own understanding

   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。

Let’s talk about the configuration of the virtual host in the nginx environment

Assume that the virtual host domain name we need to configure is mail.zjc.com

---

The virtual host storage directory is /var /www/mail.zjc.com/web
sudo mkdir -p /var/www/mail.zjc.com/web

---

Create nginx virtual host configuration file
sudo gedit /etc/nginx/sites-available /mail.zjc.com.vhost
The content is (where the php domain is configured according to the local PHP application)

<code><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;
        }
}</code>

Because nginx’s main configuration file nginx.conf will automatically apply the configuration file in sites-enabled, so we need to create one in sites-enabled Link to mail.zjc.com.vhost file

<code>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></code>

---

Reload nginx to make the configuration take effect
sudo /etc/init.d/nginx reload

---

Okay, next is /var/www/mail. Create some files (such as index.php) in the zjc.com/web directory and then access them through http://mail.zjc.com/index.php. BTW, remember to set mail.zjc.com in hosts or DNS to point to the IP address of nginx.

The above introduces nginx to configure the virtual host vhost, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
