What is IPFS?
IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas from previous systems such as Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single BitTorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built-in. You can also mount the world at /ipfs.

The IPFS protocol and its implementations are still in heavy development. This means that there may be problems in our protocols, or there may be mistakes in our implementations. And -- though IPFS is not production-ready yet -- many people are already running nodes in their machines. So we take security vulnerabilities very seriously. If you discover a security issue, please bring it to our attention right away!
If you find a vulnerability that may affect live deployments -- for example, by exposing a remote execution exploit -- please send your report privately to firstname.lastname@example.org. Please DO NOT file a public issue.
If the issue is a protocol weakness that cannot be immediately exploited or something not yet deployed, just discuss it openly.
The canonical download instructions for IPFS are over at: https://docs.ipfs.io/guides/guides/install/. It is highly recommended you follow those instructions if you are not interested in working on IPFS development.
IPFS can run on most Linux, macOS, and Windows systems. We recommend running it on a machine with at least 2 GB of RAM and 2 CPU cores (go-ipfs is highly parallel). On systems with less memory, it may not be completely stable.
If your system is resource-constrained, we recommend:
- Installing OpenSSL and rebuilding go-ipfs manually with
make build GOTAGS=openssl. See the download and compile section for more information on compiling go-ipfs.
- Initializing your daemon with
ipfs init --profile=lowpower
More info on how to run go-ipfs inside docker can be found here.
Native Linux package managers
# pacman -Syu go-ipfs
With the purely functional package manager Nix you can install go-ipfs like this:
$ nix-env -i ipfs
You can also install the Package by using its attribute name, which is also
In solus, go-ipfs is available in the main repository as go-ipfs.
$ sudo eopkg install go-ipfs
You can also install it through the Solus software center.
Other package managers
GNU's functional package manager, Guix, also provides a go-ipfs package:
$ guix package -i go-ipfs
With snap, in any of the supported Linux distributions:
$ sudo snap install ipfs
macOS package managers
The package ipfs currently points to go-ipfs and is being maintained.
$ sudo port install ipfs
In macOS you can use the purely functional package manager Nix:
$ nix-env -i ipfs
You can also install the Package by using its attribute name, which is also
A Homebrew formula ipfs is maintained too.
$ brew install --formula ipfs
Windows package managers
PS> choco install ipfs
go-ipfs in its 'extras' bucket.
PS> scoop bucket add extras PS> scoop install go-ipfs
Install prebuilt binaries
- Click the blue "Download go-ipfs" on the right side of the page.
- Open/extract the archive.
ipfsto your path (
install.shcan do it for you).
You can also download go-ipfs from this project's GitHub releases page if you are unable to access dist.ipfs.io:
Build from Source
go-ipfs's build system requires Go and some standard POSIX build tools:
- GNU make
- GCC (or some other go compatible C Compiler) (optional)
To build without GCC, build with
make build CGO_ENABLED=0).
If you need to update: Download latest version of Go.
You'll need to add Go's bin directories to your
$PATH environment variable e.g., by adding these lines to your
/etc/profile (for a system-wide installation) or
export PATH=$PATH:/usr/local/go/bin export PATH=$PATH:$GOPATH/bin
(If you run into trouble, see the Go install instructions).
Download and Compile IPFS
$ git clone https://github.com/ipfs/go-ipfs.git $ cd go-ipfs $ make install
Alternatively, you can run
make build to build the go-ipfs binary (storing it in
cmd/ipfs/ipfs) without installing it.
NOTE: If you get an error along the lines of "fatal error: stdlib.h: No such file or directory", you're missing a C compiler. Either re-run
CGO_ENABLED=0 or install GCC.
Compiling for a different platform is as simple as running:
make build GOOS=myTargetOS GOARCH=myTargetArchitecture
To build go-ipfs with OpenSSL support, append
GOTAGS=openssl to your
make invocation. Building with OpenSSL should significantly reduce the background CPU usage on nodes that frequently make or receive new connections.
Note: OpenSSL requires CGO support and, by default, CGO is disabled when cross-compiling. To cross-compile with OpenSSL support, you must:
- Install a compiler toolchain for the target platform.
- Set the
- Separate instructions are available for building on Windows.
gitis required in order for
go getto fetch all dependencies.
- Package managers often contain out-of-date
golangpackages. Ensure that
go versionreports at least 1.10. See above for how to install go.
- If you are interested in development, please install the development dependencies as well.
- WARNING: Older versions of OSX FUSE (for Mac OS X) can cause kernel panics when mounting!- We strongly recommend you use the latest version of OSX FUSE. (See https://github.com/ipfs/go-ipfs/issues/177)
- Read docs/fuse.md for more details on setting up FUSE (so that you can mount the filesystem).
- Shell command completions can be generated with one of the
ipfs commands completionsubcommands. Read docs/command-completion.md to learn more.
- See the misc folder for how to connect IPFS to systemd or whatever init system your distro uses.
IPFS has an updating tool that can be accessed through
ipfs update. The tool is
not installed alongside IPFS in order to keep that logic independent of the main
codebase. To install
ipfs update, download it here.
Downloading IPFS builds using IPFS
List the available versions of go-ipfs:
$ ipfs cat /ipns/dist.ipfs.io/go-ipfs/versions
Then, to view available builds for a version from the previous command ($VERSION):
$ ipfs ls /ipns/dist.ipfs.io/go-ipfs/$VERSION
To download a given build of a version:
$ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_darwin-386.tar.gz # darwin 32-bit build $ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_darwin-amd64.tar.gz # darwin 64-bit build $ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_freebsd-amd64.tar.gz # freebsd 64-bit build $ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_linux-386.tar.gz # linux 32-bit build $ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_linux-amd64.tar.gz # linux 64-bit build $ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_linux-arm.tar.gz # linux arm build $ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_windows-amd64.zip # windows 64-bit build
To start using IPFS, you must first initialize IPFS's config files on your
system, this is done with
ipfs init. See
ipfs init --help for information on
the optional arguments it takes. After initialization is complete, you can use
ipfs add and any of the other commands to explore!
Some things to try
Basic proof of 'ipfs working' locally:
echo "hello world" > hello ipfs add hello # This should output a hash string that looks something like: # QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o ipfs cat <that hash>
If you have previously installed IPFS before and you are running into problems getting a newer version to work, try deleting (or backing up somewhere else) your IPFS config directory (~/.ipfs by default) and rerunning
ipfs init. This will reinitialize the config file to its defaults and clear out the local datastore of any bad entries.
Please direct general questions and help requests to our forum or our IRC channel (freenode #ipfs).
If you believe you've found a bug, check the issues list and, if you don't see your problem there, either come talk to us on IRC (freenode #ipfs) or file an issue of your own!

Map of go-ipfs Subsystems
WIP: This is a high-level architecture diagram of the various sub-systems of go-ipfs. To be updated with how they interact. Anyone who has suggestions is welcome to comment here on how we can improve this!
CLI, HTTP-API, Architecture Diagram
Description: Dotted means "likely going away". The "Legacy" parts are thin wrappers around some commands to translate between the new system and the old system. The grayed-out parts on the "daemon" diagram are there to show that the code is all the same, it's just that we turn some pieces on and some pieces off depending on whether we're running on the client or the server.
If you make changes to the protocol buffers, you will need to install the protoc compiler.
