Memcached

Step by step instruction on how to install memcached servers in your machine:

In windows machine:
+ Download the attached memcached.exe to a folder, say "B:\Memcached".
+ Open "Command Prompt" as an administrator.
+ To start two instances of the server in two ports, execute:
sc create "server1" binPath= "B:\Memcached\memcached.exe -d runservice -p 11211" DisplayName= "server1" start= auto
sc create "server2" binPath= "B:\Memcached\memcached.exe -d runservice -p 11212" DisplayName= "server2" start= auto
+ Now to start the servers execute:
sc start server1
sc start server2
+ To remove the services:
sc delete server1
sc delete server2

In linux machine:
Method 1:
+ Execute: yum install memcached (This is for redhat and might vary for other linux distributions)
+ To verify installation execute: memcached -h
+ Run memcached server as daemon on port 11211: memcached -l 0.0.0.0 -p 11211 -d
+ Run memcached server as daemon on port 11212: memcached -l 0.0.0.0 -p 11212 -d
+ Verify the service: ps -e | grep memcached
