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 RedHat, 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:
root-shell> apt-get install memcached
To install memcached on a Gentoo host, use emerge:
root-shell> emerge install memcached
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 epoll
interface. For all platforms, ensure that you have
libevent 1.1 or higher installed. You can
obtain libevent from
libevent
web page.
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 memcached-
1.2.5directory:shell> cd memcached-
1.2.5Run configure
shell> ./configure
Some additional options you may want to specify to configure:
--prefixIf you want to specify a different installation directory, use the
--prefixoption:shell> ./configure --prefix=/opt
The default is to use the
/usr/localdirectory.--with-libeventIf you have installed
libeventand configure cannot find the library, use the--with-libeventoption to specify the location of the installed library.--enable-64bitTo build a 64-bit version of memcached (which enables you to use a single instance with a large RAM allocation), use --enable-64bit.
--enable-threadsTo 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 14.5.2.7, “memcached thread Support”.--enable-dtracememcached includes a range of DTrace threads that can be used to monitor and benchmark a memcached instance. For more information, see Section 14.5.2.5, “Using memcached and DTrace”.
Run make to build memcached:
