Table of Contents
Step-1: Install Ruby interpreter
Please install Ruby >= 1.9.3 and bundler on your local environment.
Step-2: Fetch Source Code
Fetch the source code from github. The official repository is located here.
$ git clone https://github.com/fluent/fluentd.git $ cd fluentd $ git checkout -b v0.12 origin/v0.12
master branch is now for v0.14 development so you need to checkout v0.12 branch.
Step-3: Build and Install
Build the package with rake and install it with gem.
$ bundle install Fetching gem metadata from https://rubygems.org/......... ... Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed. $ bundle exec rake build fluentd xxx built to pkg/fluentd-xxx.gem. $ gem install pkg/fluentd-xxx.gem
Step-4: Run
Run the following commands to to confirm that Fluentd was installed successfully:
$ fluentd --setup ./fluent $ fluentd -c ./fluent/fluent.conf -vv & $ echo '{"json":"message"}' | fluent-cat debug.test
The last command sends Fluentd a message ‘{“json”:”message”}’ with a “debug.test” tag. If the installation was successful, Fluentd will output the following message:
2011-07-10 16:49:50 +0900 debug.test: {"json":"message"}
| It's HIGHLY recommended that you set up ntpd on the node to prevent invalid timestamps in your logs. |
| For large deployments, you must use jemalloc to avoid memory fragmentation. This is already included in the rpm and deb packages. |
