Prebuilt binaries

You can download prebuilt binaries for linux on the release page.

Install from crates.io:

Build from source:

• Clone the repo
• If you want to use all features run 'cargo build --release' or if you only want to serve static files run 'cargo build --release --no-default-features'
• Modify the config.toml to your needs
• Run './target/release/gemserv config.toml'

Init scripts

In the init-scripts directory there's OpenRC(Courtesy of Tastytea) and systemd service files.

CGI and SCGI

There's example SCGI scripts for python and perl in the cgi-scripts directory.

In the configuration file there's "cgi" which is an optional bool to turn cgi on. If it's true it'll run scripts from any directory. To limit it to only one directory set "cgipath"

If "cgi" is false or not set the server will respond "Not Found" to any executable file.

Scripts have 5 seconds to complete or they will be terminated.

• SCRIPT_NAME
• REMOTE_ADDR
• REMOTE_HOST
• REMOTE_PORT
