Match Rule Definitions
Match rules are defined in the file /var/eq/eq.conf with the definition of the cluster to which the match rule applies.
A match rule as it appears in eq.conf looks like the following example:
match ma01 {
client_ip("10.0.0.19")
} then {
flags = !spoof;
servers = sv_01;
}
In this example (the match rule is named “ma01”), the match function,
client_ip
, has an argument that matches
all requests from IP address
10.0.0.19
, which are all sent to server sv_01. Additionally, this rule disables the
spoof
flag (that is, when the connection is made to the server, the server sees a connection to the Equalizer, not to
the client). This rule looks as follow in the Administrative Interface:
Figure 43 Example match rule
The
expression
section of the screen shows the expression that is evaluated against the incoming request. If the
expression evaluates to true , the
servers and options
section specifies the servers that will be used to satisfy the
incoming request, as well as the options that will be set for the request. The next section of this document explains
all the match rule settings in detail.
If the incoming client IP address
matches this expression...
...then, load balance the request
across the selected servers...
...and disable the spoof option
(leave all other options set to
the cluster settings).
