Getting Started

Confluent is intended to be used in conjunction with xCAT. The following documentation assumes that xCAT is already installed and configured on the management node.

Download confluent

To build from source, ensure your machine has the correct development packages to build rpms, then execute the following:

  • Clone the git repo:

    git clone
  • Build the confluent-server and confluent-client packages:

    cd confluent/confluent_server ; ./buildrpm ; cd -
    cd confluent/confluent_client ; ./buildrpm ; cd -



The following example describes the steps for rhels7.5 on ppc64le:

yum install libffi-devel.ppc64le
yum install openssl-devel
pip install crypto pyasn1 pycrypto eventlet pyparsing netifaces scrapy pysnmp paramiko pyghmi pyte


Installing xCAT-confluent via rpm:

rpm -ivh /root/rpmbuild/RPMS/noarch/confluent_server-*.noarch.rpm --nodeps
rpm -ivh /root/rpmbuild/RPMS/noarch/confluent_client-*.noarch.rpm --nodeps

You may find it helpful to add the confluent paths into your system path:



Starting/Stopping confluent

To start confluent:

service confluent start

To stop confluent:

service confluent stop

If you want confluent daemon to start automatically at bootup, add confluent service to chkconfig:

chkconfig confluent on

Replacing conserver with confluent

A new keyword, consoleservice, has been added to the xCAT site table to allow the system administrator to control between conserver and confluent. If consoleservice is not set, default behavior is to use conserver.

Set the consoleservice to confluent:

chdef -t site consoleservice='confluent'

Run makeconfluentcfg to create the confluent configuration files:


Use rcons as before to start the console session.:

rcons <singlenode>

Web Browser access

Confluent-api and confluent-consoles are able to be accessed from the browser. It is highly recommended that you create a non-root user to access the sessions:

Create the non-root user on the management node
# useradd -m xcat

Create a non-root user in confetty
# /opt/confluent/bin/confetty create users/xcat

Set the password for the non-root user
# /opt/confluent/bin/confetty set users/xcat password="mynewpassword"

Rest Explorer

Configure the httpd configuration for confluent-api by creating a confluent.conf file under /etc/httpd/conf.d/ directory:

The example uses server ip: and port 4005

# cat /etc/httpd/conf.d/confluent.conf
LoadModule proxy_http_module modules/
<Location /confluent-api>

# restart httpd
service httpd restart

Now point your browser to: http://<server ip>:<port> and log in with the non-root user and password created above.

Confluent consoles

confluent-web is provided in a subdirectory under the confluent project confluent_web

Download the content of that directory to /var/www/html/confluent and point your browser to:

http://<server ip>/confluent/consoles.html
