一、建立站點配置檔案

1、在 nginx conf 目錄中建立 conf.d 資料夾以及配置檔案，這裡假設站點為 www.a.com

$ pwd  
/usr/local/nginx/conf  
$ sudo mkdir conf.d
$ sudo vim conf.d/www.a.com.conf #新站點配置檔案  

2、將如下內容寫入 www.a.com.conf 檔案中，該內容可從 nginx.cnf 檔案中擷取 server 節點修改。

修改以下兩點：

server_name www.a.com; #此處 www.a.com 為訪問域名

root /home/www/www.a.com; #檔案存放目錄,此處 www.a.com 為資料夾名稱

修改結果如下：

server {  
     listen       9999;  
     server_name  www.a.com; #此處 www.a.com 為訪問域名  

     #charset koi8-r;  

     #access_log  logs/host.access.log  main;  

     location / {  
         root   /home/www/www.a.com; #檔案存放目錄,此處 www.a.com 為資料夾名稱  
         index  index.html index.htm;  
     }  

     #error_page  404              /404.html;  
 


     # redirect server error pages to the static page /50x.html  
     #  
     error_page   500 502 503 504  /50x.html;  
     location = /50x.html {  
         root   html;  
     }  
 }  

二、建立Nginx配置檔案

在 http 節點最底部增加 include conf.d/*.conf; nginx配置檔案是順序載入的！

修改完畢，內容如下：

#user  nobody;  
worker_processes  1
 
;  

#error_log  logs/error.log;  
#error_log  logs/error.log  notice;  
#error_log  logs/error.log  info;  

#pid        logs/nginx.pid;  


events {  
    worker_connections  1024;  
}  


http {  
    include       mime.types;  
    default_type  application/octet-stream;  

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '  
    #                  '$status $body_bytes_sent "$http_referer" '  
    #                  '"$http_user_agent" "$http_x_forwarded_for"';  

    #access_log  logs/access.log  main;  

    sendfile        on;  
    #tcp_nopush     on;  

    #keepalive_timeout  0;  
    keepalive_timeout  65;  

    #gzip  on;  

    server {  
        listen       80;  
        server_name  localhost;  

        #charset koi8-r;  

        #access_log  logs/host.access.log  main;  

        location / {  
            root   html;  
            index  index.html index.htm;  
        }  

        #error_page  404              /404.html;  

        # redirect server error pages to the static page /50x.html  
        #  
        error_page   500 502 503 504  /50x.html;  
        location = /50x.html {  
            root   html;  
        }  

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80  
        #  
        #location ~ \.php$ {  
        #    proxy_pass   http://127.0.0.1;  
        #}  

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000  
        #  
        #location ~ \.php$ {  
        #    root           html;  
        #    fastcgi_pass   127.0.0.1:9000;  
        #    fastcgi_index  index.php;  
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;  
        #    include        fastcgi_params;  
        #}  

        # deny access to .htaccess files, if Apache's document root  
        # concurs with nginx's one  
        #  
        #location ~ /\.ht {  
        #    deny  all;  
        #}  
    }  


    # another virtual host using mix of IP-, name-, and port-based configuration  
    #  
    #server {  
    #    listen       8000;  
    #    listen       somename:8080;  
    #    server_name  somename  alias  another.alias;  

    #    location / {  
    #        root   html;  
    #        index  index.html index.htm;  
    #    }  
    #}  


    # HTTPS server  
    #  
    #server {  
    #    listen       443 ssl;  
    #    server_name  localhost;  

    #    ssl_certificate      cert.pem;  
    #    ssl_certificate_key  cert.key;  

    #    ssl_session_cache    shared:SSL:1m;  
    #    ssl_session_timeout  5m;  

    #    ssl_ciphers  HIGH:!aNULL:!MD5;  
    #    ssl_prefer_server_ciphers  on;  

    #    location / {  
    #        root   html;  
    #        index  index.html index.htm;  
    #    }  
    #}  

    include  /usr/local/nginx/conf/conf.d/*.conf; #載入多站點配置檔案
    } 

三、建立測試環境

1、建立測試網頁資訊

$ pwd  
/home
$ sudo mkdir -p www/www.a.com  
$ sudo sh -c "echo Hello World>www/www.a.com/index.html"  
$ cat www/www.a.com/index.html  #檢視寫入內容  
Hello World 

2、修改本地hosts 檔案，新增 www.a.com 跳轉到 127.0.0.1

t$ sudo vim /etc/hosts  
$ cat /etc/hosts|grep www.a.com # 檢視修改結果  
127.0.0.1   www.a.com 

四、重啟 Nginx ，關於Nginx 服務配置參見 Ubuntu 12.04 Nginx 安裝記錄

$ sudo service nginx restart
