nginx裡面的sites-available和sites-enabled有什麼差別

Question

一般修改配置改哪個的呢？我想改和php連線的設定

Answer 1

  If you are coming from Apache, the "sites-available" and "sites-enabled" 
directories will be familiar.

  These directories are used to define configurations for your websites. 
Files are generally created in the "sites-available" directory, and then
symbolically linked to the "sites-enabled" directory when they are ready 
to go live.

...

In the "nginx.conf" file, we can see that the end of the "http" block has:

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

How To Configure Nginx

sites-available是存放目前的server配置, 在這裡修改

sites-enabled是啟動並使用的server配置（從sites_available的檔案建立捷徑到sites-enabled）
