Nix Installation Guide
This guide describes various methods for installing Nix.
To install Nix from any Linux distribution, use the following two commands. (Note: This assumes you have the permission to use
sudo, and you are logged in as the user you want to install Nix for.)
$ sudo install -d -m755 -o $(id -u) -g $(id -g) /nix $ curl https://nixos.org/nix/install | sh
After that being done, you can use all Nix commands as a normal user without any special permissions (for example by using
Installing without root permissions
By using the
--store parameter in nix 2.0 or PRoot,
you can use Nix on systems where you have no permission to create the `/nix` directory.
nix run is the preferred and faster option.
However, it might not run on older Linux kernels, or kernels without user namespace support.
With the following command, you can test whether your system supports user namespaces
for unprivileged users:
$ unshare --user --pid echo YES YES
The output should be
If the command is absent, an alternative is to check the kernel compile options:
$ zgrep CONFIG_USER_NS /proc/config.gz CONFIG_USER_NS=y
On some systems, like Debian or Ubuntu, the kernel configuration is in a different place, so instead use:
$ grep CONFIG_USER_NS /boot/config-$(uname -r) CONFIG_USER_NS=y
If the output of this command is
CONFIG_USER_NS=y, then your system supports user namespaces.
nix-user-chroot is the preferred method to install use nix on systems without
/nix. It also requires user namespaces to be enabled on the system.
nix-user-chroot will create an environment in which you can bind mount an directory to
The mountpoint will be only visible within this environment.
In this example, the Nix store will be installed to
$ mkdir -m 0755 ~/.nix $ nix-user-chroot ~/.nix bash -c 'curl https://nixos.org/nix/install | sh'
Note that you can only use Nix and the installed programs within the shell started by
$ nix-user-chroot ~/.nix bash
Precompiled PRoot binaries can be downloaded from here
The following commands will install Nix the Nix store to
# first make sure the executable bit is set on the binary $ chmod +x proot_5.1.1_x86_64_rc2--no-seccomp $ mkdir ~/.nix $ ./proot_5.1.1_x86_64_rc2--no-seccomp -b ~/.nix:/nix
This will start a new shell, where Nix can be installed:
$ curl https://nixos.org/nix/install | sh
Note that you can only use Nix and the installed programs within the shell started by PRoot.
nix 2.0's native method
If nix is already installed on the system i.e. a self-compiled nix itself can also create
a nix store in an alternative user-writable locations.
The following command will create a nix store in
~/my-nix and spawn a shell, where
~/my-nix be mounted to
$ nix run --store ~/my-nix nixpkgs.nix nixpkgs.bashInteractive
You can make all nix commands use the alternate store by specifying it in `~/.config/nix/nix.conf` as
store = /home/USERNAME/my-nix.
