Dependencies

Installation

Use the command below to install the dependencies mentioned above, and build the binary into $GOPATH/bin.

go get -u github.com/m3ng9i/ran

For convenience, you can move the ran binary to a directory in the PATH environment variable.

You can also call ./build.py command under the Ran source directory to write version information into the binary, so that ran -v will give a significant result. Run ./build.py -h for help.

Running with Docker

docker run -d -p 8080:8080 -v /public:/web m3ng9i/ran

Directory volume mounted to /web will be served by default.

Below is another example, the options -l -404 /404page.html are passed to the ran binary:

docker run --name ran -d -p 8080:8080 -v /public:/web:ro m3ng9i/ran -l -404 /404page.html

Download binary

You can also download the Ran binary without building it yourself.

Download Ran binary from the release page.

Run Ran

You can start a web server without any options by typing ran and pressing return in terminal window. This will use the following default configuration:

Configuration	Default value
Root directory	the current working directory
IP binding	0.0.0.0
Port	8080
Index file	index.html, index.htm
List files of directories	false
Serve all path	false
Gzip	true
Disable caching	false
Write cross-origin headers	false
Digest auth	false
TLS encryption	off

Open http://127.0.0.1:8080 in browser to see your website.

You can use the command line options to override the default configuration.

Options:

    -r,  -root=<path>           Root path of the site. Default is current working directory.
    -b,  -bind-ip=<ip>          Bind one or more IP addresses to the ran web server.
                                Multiple IP addresses should be separated by comma.
                                If not provide this Option, ran will use 0.0.0.0.
    -p,  -port=<port>           HTTP port. Default is 8080.
         -404=<path>            Path of a custom 404 file, relative to Root. Example: /404.html.
    -i,  -index=<path>          File name of index, priority depends on the order of values.
                                Separate by colon. Example: -i "index.html:index.htm"
                                If not provide, default is index.html and index.htm.
    -l,  -listdir=<bool>        When request a directory and no index file found,
                                if listdir is true, show file list of the directory,
                                if listdir is false, return 404 not found error.
                                Default is false.
    -sa, -serve-all=<bool>      Serve all paths even if the path is start with dot. Default is false.
    -g,  -gzip=<bool>           Turn on or off gzip compression. Default value is true (means turn on).

    -nc, -no-cache=<bool>       If true, ran will remove Last-Modified header and write some no-cache headers to the response:
                                    Cache-Control: no-cache, no-store, must-revalidate
                                    Pragma: no-cache
                                    Expires 0
                                Default is false.

         -cors=<bool>           If true, ran will write some cross-origin resource sharing headers to the response:
                                    Access-Control-Allow-Origin: *
                                    Access-Control-Allow-Credentials: true
                                    Access-Control-Allow-Methods: *
                                    Access-Control-Allow-Headers: *
                                If the request header has a Origin field, then it's value is used in Access-Control-Allow-Origin.
                                Default is false.

    -am, -auth-method=<auth>    Set authentication method, valid values are basic and digest. Default is basic.
    -a,  -auth=<user:pass>      Turn on authentication and set username and password (separate by colon).
                                After turn on authentication, all the page require authentication.
         -401=<path>            Path of a custom 401 file, relative to Root. Example: /401.html.
                                If authentication fails and 401 file is set,
                                the file content will be sent to the client.

         -tls-port=<port>       HTTPS port. Default is 443.
         -tls-policy=<pol>      This option indicates how to handle HTTP and HTTPS traffic.
                                There are three option values: redirect, both and only.
                                redirect: redirect HTTP to HTTPS
                                both:     both HTTP and HTTPS are enabled
                                only:     only HTTPS is enabled, HTTP is disabled
                                The default value is: only.
         -cert=<path>           Load a file as a certificate.
                                If use with -make-cert, will generate a certificate to the path.
         -key=<path>            Load a file as a private key.
                                If use with -make-cert, will generate a private key to the path.

Other options:

         -make-cert             Generate a self-signed certificate and a private key used in TLS encryption.
                                You should use -cert and -key to set the output paths.
         -showconf              Show config info in the log.
         -debug                 Turn on debug mode.
    -v,  -version               Show version information.
    -h,  -help                  Show help message.

If you want to shutdown Ran, type ctrl+c in the terminal, or kill it in the task manager.

Examples

Example 1: Start a server in the current directory and set port to 8888

ran -p=8888

Example 2: Set root to /tmp, list files of directories and set a custom 404 page

ran -r=/tmp -l=true -404=/404.html

-l=true can be shorted to -l for convenience.

Example 3: Turn off gzip compression, set access username and password and set a custom 401 page

ran -g=false -a=user:pass -401=/401.html

Example 4: Set custom index file

ran -i default.html:index.html

Example 5: Turn on TLS encryption

If you want to turn on TLS encryption (https), you should use -cert to load a certificate and -key to load a private key.

The default TLS port is 443, you can use -tls-port to set it to another port.

The following command load a certificate and a private key, and set TLS port to 9999. It can be browsed at https://127.0.0.1:9999.

ran -cert=/path/to/cert.pem -key=/path/to/key.pem -tls-port=9999

Example 6: Control HTTP and HTTPS traffic

When you turn on TLS, you can choose to disable HTTP, redirect HTTP to HTTPS or let them work together.

You can use -tls-policy to control HTTP and HTTPS traffic:

If set to "redirect", all HTTP traffic will be redirect to HTTPS.
If set to "both", both HTTP and HTTPS are enabled.
If set to "only", only HTTPS is enabled, HTTP is disabled.

If not provide -tls-policy, the default value "only" will be used.

An example:

ran -cert=cert.pem -key=key.pem -tls-policy=redirect

Example 7: Create a self-signed certificate and a private key

For testing purposes or internal usage, you can use -make-cert to create a self-signed certificate and a private key.

ran -make-cert -cert=/path/to/cert.pem -key=/path/to/key.pem

Example 8: Custom IP binding

ran -b=127.0.0.12,192.168.0.34

Tips and tricks

Execute permission

Before running Ran binary or build.py, make sure they have execute permission. If don't, use chmod u+x <filename> to set.

download parameter

If you add download as a query string parameter in the url, the browser will download the file instead of displaying it in the browser window. Example:

http://127.0.0.1:8080/readme.html?download

gzip parameter

Gzip compression is enabled by default. Ran will gzip file automaticly according to the file extension. Example: a .txt file will be compressed and a .jpg file will not.

If you add gzip=true in the url, Ran will force compress the file even if the file should not be compressed. Example:

http://127.0.0.1:8080/picture.jpg?gzip=true

If you add gzip=false in the url, Ran will not compress it even if it should be compressed. Example:

http://127.0.0.1:8080/large-file.txt?gzip=false

Read the source code of CanBeCompressed() to learn more about automatic gzip compression.
