Memcached is a high performance multithreaded event-based key/value cache store intended to be used in a distributed system.

• libevent, https://www.monkey.org/~provos/libevent/ (libevent-dev)
• libseccomp, (optional, experimental, linux) - enables process restrictions for better security. Tested only on x86_64 architectures.

To build memcached in your machine from local repo you will have to install autotools, automake and libevent. In a debian based system the installation and compilation commands look like this:

sudo apt-get install autotools-dev
sudo apt-get install automake
sudo apt-get install libevent-dev
rm -rf memcached
git clone https://github.com/memcached/memcached.git
cd memcached 
./autogen.sh
./configure --enable-extstore
make
make test

It should create the binary in the same folder, which you can run

./memcached

You can telnet into that memcached to ensure it is up and running

telnet 127.0.0.1 11211
stats

Be warned that the -k (mlockall) option to memcached might be dangerous when using a large cache. Just make sure the memcached machines don't swap. memcached does non-blocking network I/O, but not disk. (it should never go to disk, or you've lost the whole point of it)
