This article explains how to install the td-agent deb package, the stable Fluentd distribution package maintained by Treasure Data, Inc.
NOTE: For Ubuntu, "14.04 LTS / Precise", "12.04 LTS / Lucid", "10.04 LTS / Lucid" are currently supported. For Debian, Squeeze and Wheezy are supported. If you are interested in other versions/platforms, please contact us on the mailing list. If enough people express interest, we may consider supporting it.
Fluentd is written in Ruby for flexibility, with performance sensitive parts written in C. However, some users may have difficulty installing and operating a Ruby daemon.
That's why Treasure Data, Inc is providing the stable distribution of Fluentd, called td-agent. The differences between Fluentd and td-agent can be found here.
NOTE: This installation guide is for td-agent v2, the current stable version. See this page for the comparison between v1 and v2. Here is the deb installation guide for v1.
Please follow the Preinstallation Guide to configure your OS properly. This will prevent many unnecessary problems.
For Ubuntu, "Ubuntu 14.04 LTS / Trusty", "Ubuntu 12.04 LTS / Precise" and "Ubuntu 10.04 LTS / Lucid" are currently supported.
For Debian, Wheezy and Squeeze are currently supported.
A shell script is provided to automate the installation process for each version. The shell script registers a new apt repository at /etc/apt/sources.list.d/treasure-data.list and installs the td-agent deb package.
For Trusty,
$ curl -L http://toolbelt.treasuredata.com/sh/install-ubuntu-trusty-td-agent2.sh | sh

$ curl -L http://toolbelt.treasuredata.com/sh/install-ubuntu-precise-td-agent2.sh | sh

NOTE: It's HIGHLY recommended that you set up ntpd on the node to prevent invalid timestamps in your logs.
The /etc/init.d/td-agent script is provided to start, stop, or restart the agent.
$ /etc/init.d/td-agent restart
$ /etc/init.d/td-agent status
td-agent (pid 21678) is running...
The following commands are supported:
$ /etc/init.d/td-agent start
$ /etc/init.d/td-agent stop
$ /etc/init.d/td-agent restart
$ /etc/init.d/td-agent status
Please make sure your configuration file is located at /etc/td-agent/td-agent.conf.
By default, /etc/td-agent/td-agent.conf is configured to take logs from HTTP and route them to stdout (/var/log/td-agent/td-agent.log). You can post sample log records using the curl command.
$ curl -X POST -d 'json={"json":"message"}' http://localhost:8888/debug.test
