» Install 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.
After downloading Serf, unzip the package. Copy the
serf binary to
somewhere on the PATH so that it can be executed. On Unix systems,
/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
$GOPATH/bin/serf), however we recommend running an official
» OS X
If you are using homebrew as a package manager,
than you can install serf as simple as:
brew install serf
» Verifying the Installation
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!
