快速搭建一个静态文件服务

Posted on | Comments: | Views:

前几天朋友问我如何在没有 root 权限且无法编辑 Nginx 配置的条件下，搭建一个静态文件服务。

我最快想到的是用 Go 写一个程序，直接在目标机器上执行 Go 编译好的二进制文件，应该不会超过 10 行代码。

本着不重复造轮子的想法（另一个主要原因是朋友当时非常着急），尝试找了找前人造好的轮子，于是找到了这个项目：https://github.com/philippgille/serve。

看了一下介绍，和我的想法相同，同时提供了便于扩展的参数，而且提供了各个平台编译好的可执行文件。

安装

Windowns 安装

1
scoop install serve

Mac 安装

1
brew install philippgille/tap/serve

Linux 安装

2
wget https://download.jpanj.com/serve_v0.3.2_Linux_x64.zip
unzip serve_v0.3.2_Linux_x64.zip .

运行

检查 serve 版本

2
$ serve -v
serve version: v0.3.2

服务监听 8100 端口并将当前目录作为静态文件根目录

$ serve -p 8100

Serving "." on all network interfaces (0.0.0.0) on HTTP port: 8100

Local network interfaces and their IP addresses so you can pass one to your colleagues:
      Interface      |  IPv4 Address   |              IPv6 Address
---------------------|-----------------|----------------------------------------
lo                   | 127.0.0.1       | ::1
eth0                 | xxx.xxx.xx.xxx  | fe80::a8aa:ff:fe11:fb4b
docker0              | 172.17.0.1      | fe80::42:1dff:fe8b:c5fe
br-556c0122836a      | 172.24.0.1      | fe80::42:92ff:fe47:2965

You probably want to share:
http://xxx.xxx.xx.xxx:8100

-d 指定文件根目录

1
$ serve -p 8100 -d "/opt"

-a 启用 Basic 认证

1
$ serve -p 8100 -d "/opt" -a "test:test"

-s 生成一个自签名证书（7天有效期），开启 https 协议

1
$ serve -p 8100 -d "/opt" -a "test:test" -s

-b 指定监听的网络接口，默认为 0.0.0.0

1
$ serve -p 8100 -d "/opt" -a "test:test" -b "0.0.0.0"

Usage of serve:
  -a string
    	Require basic authentication with the given credentials (e.g. -a "alice:secret")
  -b string

  -d string
    	The directory of static files to host (default ".")
  -h	Print the usage
  -p string
    	Port to serve on. 8080 by default for HTTP, 8443 for HTTPS (when using the -s flag) (default "8080")
  -s	Serve via HTTPS instead of HTTP. Creates a temporary self-signed certificate for localhost, 127.0.0.1, <hostname>.local, <hostname>.lan, <hostname>.home and the determined LAN IP address
  -t	Test / dry run (just prints the interface table)
  -v	Print the version
