2. Quick Start¶
This section describes the basic steps needed to get Kea up and running. For further details, full customizations, and troubleshooting, see the respective chapters elsewhere in this Kea Administrator Reference Manual (ARM).
2.1. Quick Start Guide for DHCPv4 and DHCPv6 Services¶
Install required run-time and build dependencies. See Build Requirements for details.
Extract the tarball. For example:
$ tar xvzf kea-1.6.0.tar.gz
Go into the source directory and run the configure script:
$ cd kea-1.6.0 $ ./configure [your extra parameters]
Install it (by default it will be placed in
/usr/local/, so it is likely that you will need root privileges for this step):
# make install
Edit the Kea configuration files which by default are installed in the
[kea-install-dir]/etc/kea/directory. These are:
kea-ctrl-agent.conf, for DHCPv4 server, DHCPv6 server, D2, and Control Agent, respectively.
In order to start the DHCPv4 server in the background, run the following command (as root):
# keactrl start -s dhcp4
Or run the following command to start the DHCPv6 server instead:
# keactrl start -s dhcp6
Note that it is also possible to start all servers simultaneously:
# keactrl start
Verify that the Kea server(s) is/are running:
# keactrl status
A server status of “inactive” may indicate a configuration error. Please check the log file (by default named
[kea-install-dir]/var/log/kea-ctrl-agent.log) for the details of the error.
If the server has been started successfully, test that it is responding to DHCP queries and that the client receives a configuration from the server; for example, use the ISC DHCP client.
Stop running the server(s):
# keactrl stop
The details of
keactrl script usage can be found in
Managing Kea with keactrl.
2.2. Running the Kea Servers Directly¶
The Kea servers can be started directly, without the need to use
keactrl. To start the DHCPv4 server run the following command:
# kea-dhcp4 -c /path/to/your/kea4/config/file.json
Similarly, to start the DHCPv6 server run the following command:
# kea-dhcp6 -c /path/to/your/kea6/config/file.json
