Install Rudder agent on RHEL or CentOS or derivatives

If you are working on a test system, you can use the quick install script:

curl https://repository.rudder.io/tools/rudder-setup | bash -s setup-agent 6.1 [policy server hostname or ip]

That will automatically execute the following steps.

Dependencies

If you need to use syslog reporting, which is not the general case, Rudder agent requires that a syslog server is installed on the node. This syslog server can be either syslogd, syslog-ng or rsyslog.

One of them is generally installed by default, but it may not be the case with minimal images. In this case you should install one (preferably syslog-ng or rsyslog).

Installation

Each official package is signed with our GPG signature. To ensure the packages you will install are official builds and have not been altered, import our key into rpm using the following command:

rpm --import https://repository.rudder.io/rpm/rudder_rpm_key.pub

Our key fingerprint is:

pub  1024R/6F07D355 2012-11-09 Rudder Project (RPM release key) <security@rudder-project.org>
      Key fingerprint = 1141 A947 CDA0 4E83 82C1  B9C4 ADAB 3BD3 6F07 D355

Add a yum repository for Rudder:

echo '[Rudder_6.1]
name=Rudder 6.1
baseurl=http://repository.rudder.io/rpm/6.1/RHEL_$releasever/
gpgcheck=1
gpgkey=https://repository.rudder.io/rpm/rudder_rpm_key.pub' > /etc/yum.repos.d/rudder.repo

If you have an active subscription, use the following to get access to long term support (you need to replace the user name and the password by your Rudder account):

echo '[Rudder_6.1]
name=Rudder 6.1
username=LOGIN
password=PASSWORD
baseurl=http://download.rudder.io/rpm/6.1/RHEL_$releasever/
gpgcheck=1
gpgkey=https://download.rudder.io/rpm/rudder_rpm_key.pub' > /etc/yum.repos.d/rudder.repo

Or for RHEL/CentOS < 7:

echo '[Rudder_6.1]
name=Rudder 6.1
baseurl=https://LOGIN:PASSWORD@download.rudder.io/rpm/6.1/RHEL_$releasever/
gpgcheck=1
gpgkey=https://LOGIN:PASSWORD@download.rudder.io/rpm/rudder_rpm_key.pub' > /etc/yum.repos.d/rudder.repo

  • on Amazon Linux:

echo '[Rudder_6.1]
name=Rudder 6.1
baseurl=http://repository.rudder.io/rpm/6.1/RHEL_6/
gpgcheck=1
gpgkey=https://repository.rudder.io/rpm/rudder_rpm_key.pub' > /etc/yum.repos.d/rudder.repo

  • on Amazon Linux 2:

echo '[Rudder_6.1]
name=Rudder 6.1
baseurl=http://repository.rudder.io/rpm/6.1/RHEL_7/
gpgcheck=1
gpgkey=https://repository.rudder.io/rpm/rudder_rpm_key.pub' > /etc/yum.repos.d/rudder.repo

Install the package:

yum install rudder-agent

Configuration

Configure the agent

Configure the IP address or hostname of the Rudder Root Server in the following file

rudder agent policy-server <rudder server ip or hostname>

We advise you to use the IP address of the Rudder root server. The DNS name of this server can also be used if you have a trusted DNS infrastructure with proper reverse resolutions.

Add the node to the server

Several minutes after the start of the agent, the new node should be pending in the Rudder web interface. You will be able to browse its inventory, and accept it to manage its configuration with Rudder.

You may force the agent to run and send an inventory by issuing the following command:

rudder agent inventory

You may force the agent run by issuing the following command:

rudder agent run

By default, a node listens on port 5309 to allow remote agent trigger. This feature is optional and can be disabled for security reason.
