2.4 . Configuring luci wit h /etc/sysconfi g /l uci
As of the Red Hat Enterprise Linux 6.1 release, you can configure some aspects of lu ci's behavior by
means of the /etc/sysco nfi g /l uci file. The parameters you can change with this file include
auxiliary settings of the running environment used by the init script as well as server configuration. In
addition, you can edit this file to modify some application configuration parameters. There are
instructions within the file itself describing which configuration parameters you can change by
editing this file.
In order to protect the intended format, you should not change the non-configuration lines of the
/etc/sysco nfi g /l uci file when you edit the file. Additionally, you should take care to follow the
required syntax for this file, particularly for the INIT SC R IP T section which does not allow for white
spaces around the equal sign and requires that you use quotation marks to enclose strings
containing white spaces.
The following example shows how to change the port at which lu ci is being served by editing the
/etc/sysco nfi g /l uci file.
1. Uncomment the following line in the /etc/sysco nfi g /l uci file:
#port = 4443
2. Replace 4443 with the desired port number, which must be higher than or equal to 1024 (not a
privileged port). For example, you can edit that line of the file as follows to set the port at
which lu ci is being served to 8084 (commenting the line out again would have the same
affect, as this is the default value).
port = 8084
3. Restart the lu ci service for the changes to take effect.
As the Red Hat Enterprise Linux 6.6 release, you can implement a fine-grained control over the
ciphers behind the secured connection between lu ci and the web browser with the
ssl _ci pher_l i st configuration parameter in /etc/sysco nfi g /l uci . This parameter can be
used to impose restrictions as expressed with OpenSSL cipher notation.
Important
When you modify a configuration parameter in the /etc/sysco nfi g /l uci file to redefine a
default value, you should take care to use the new value in place of the documented default
value. For example, when you modify the port at which lu ci is being served, make sure that
you specify the modified value when you enable an IP port for lu ci, as described in
Section 2.3.2, “ Enabling the IP Port for lu ci .
Modified port and host parameters will automatically be reflected in the URL displayed when
the lu ci service starts, as described in Section 3.2, “Starting lu ci . You should use this URL
to access lu ci.
