You can build and install memcached from the source code directly, or you can use an existing operating system package or installation.
Installing memcached from a Binary Distribution
To install memcached on a Red Hat, or Fedora host, use yum:
root-shell> yum install memcached
On CentOS, you may be able to obtain a suitable RPM from another source, or use the source tarball.
To install memcached on a Debian or Ubuntu host, use apt-get:

Building memcached from Source
On other Unix-based platforms, including Solaris, AIX, HP-UX and
Mac OS X, and Linux distributions not mentioned already, you must
install from source. For Linux, make sure you have a 2.6-based
kernel, which includes the improved
interface. For all platforms, ensure that you have
libevent 1.1 or higher installed. You can
You can obtain the source for memcached from memcached Web site.
To build memcached, follow these steps:
Extract the memcached source package:
shell> gunzip -c memcached-
1.2.5.tar.gz | tar xf -
Change to the
shell> cd memcached-
Some additional options you might specify to the configure:
To specify a different installation directory, use the
shell> ./configure --prefix=/opt
The default is to use the
If you have installed
configure cannot find the library, use
--with-libevent option to specify the
location of the installed library.
To build a 64-bit version of memcached
(which enables you to use a single instance with a large
RAM allocation), use
To enable multi-threading support in
memcached, which improves the response
times on servers with a heavy load, use
--enable-threads. You must have support
for the POSIX threads within your operating system to
enable thread support. For more information on the
threading support, see
Section 188.8.131.52, “memcached Thread Support”.
memcached includes a range of DTrace threads that can be used to monitor and benchmark a memcached instance. For more information, see Section 184.108.40.206, “Using memcached and DTrace”.
Run make to build memcached:
