使用nginx搭建簡單的檔案伺服器

nginx配置檔案路徑：

/etc/nginx

進入 /etc/nginx目錄
檔案結構如下：

[email protected]:/etc/nginx$ ls -lth
total 64K
drwxr-xr-x 2 root root 4.0K Oct 20 00:10 sites-available
drwxr-xr-x 2 root root 4.0K Oct 19 23:37 sites-enabled
drwxr-xr-x 2 root root 4.0K Jun  2 23:16

-rw-r--r-- 1 root root  222 Mar  5  2014 naxsi-ui.conf.1.4.1
-rw-r--r-- 1 root root 1.6K Mar  5  2014 nginx.conf
-rw-r--r-- 1 root root  180 Mar  5  2014 proxy_params

-rw-r--r-- 1 root root 3.0
 
K Mar  5  2014 win-utf

進入sites-available
有個default檔案
首先備份default檔案

cp default default.backup

然後修改default檔案如下：

 20 server {
 21         listen 80 default_server;
 22         listen [::]:80 default_server ipv6only=on;
 23 
 24         root /home/hhb/work/catmaid_5d_visualization_annotation/httpdocs/data;
 25 
 26         # Make site accessible from http://localhost/
 27         server_name localhost;
 28 
 29         location / {
 30                 # First attempt to serve request as file, then
 31                 # as directory, then fall back to displaying a 404.
 32                 try_files $uri $uri/ =404;
 33                 # Uncomment to enable naxsi on this location
 34                 # include /etc/nginx/naxsi.rules
 35                 autoindex on;
 36                 autoindex_exact_size on;
 37                 autoindex_localtime on;
 38         }

這裡root 就是nginx伺服器的根目錄
其中server_name可以自己起一個喜歡的名字
