Installing Serf |

Serf must first be installed on every node that will be a member of a Serf cluster. To make installation easy, Serf is distributed as a binary package for all supported platforms and architectures. This page will not cover how to compile Serf from source. |
Serf must first be installed on every node that will be a member of a Serf cluster. To make installation easy, Serf is distributed as a binary package for all supported platforms and architectures.
After downloading Serf, unzip the package. Copy the serf
binary to
somewhere on the PATH so that it can be executed. On Unix systems,
~/bin
and /usr/local/bin
are common installation directories,
depending on if you want to restrict the install to a single user or
expose it to the entire system. On Windows systems, you can put it wherever
you would like.
It is also possible to build and install the serf
binary through the standard
go
command-line utility (go get -u github.com/hashicorp/serf/cmd/serf
which
installs serf
as $GOPATH/bin/serf
), however we recommend running an official
release.
If you are using homebrew as a package manager, than you can install serf as simple as:
brew install serf
After installing Serf, verify the installation worked by opening a new
terminal session and checking that serf
is available. By executing
serf
you should see help output similar to that below:
$ serf
usage: serf [--version] [--help] <command> [<args>]
Available commands are:
agent Runs a Serf agent
event Send a custom event through the Serf cluster
force-leave Forces a member of the cluster to enter the "left" state
info Provides debugging information for operators
join Tell Serf agent to join cluster
keygen Generates a new encryption key
keys Manipulate the internal encryption keyring used by Serf
leave Gracefully leaves the Serf cluster and shuts down
members Lists the members of a Serf cluster
monitor Stream logs from a Serf agent
query Send a query to the Serf cluster
reachability Test network reachability
tags Modify tags of a running Serf agent
version Prints the Serf version
If you get an error that serf
could not be found, then your PATH
environmental variable was not setup properly. Please go back and ensure
that your PATH variable contains the directory where Serf was installed.
Otherwise, Serf is installed and ready to go!
