.B memcached
|
||
|
|
is a flexible memory object caching daemon designed to alleviate database load
|
||
|
|
in dynamic web applications by storing objects in memory. It's based on
|
||
|
|
libevent to scale to any size needed, and is specifically optimized to avoid
|
||
|
|
swapping and always use non-blocking I/O.

.SH OPTIONS

|
||
|

is included below.
|
||
|
|
.TP
|
||
|
|
.B \-l <ip_addr>
|
||
|
|
Listen on <ip_addr>; default to INDRR_ANY. This is an important option to
|
||
|
|
consider as there is no other way to secure the installation. Binding to an
|
||
|
|
internal or firewalled network interface is suggested.
|
||
|
|
.TP
|
||
|
|
.B \-d
|
||
