Multiple memcache instances/servers on windows

Setting up memcache on windows is like taking candy from a baby. You can find all the information and the binaries for memcache at http://jehiah.cz/projects/memcached-win32/ . Note that these binaries will also work for x64 based windows.

A little trickier is to set up multiple instances of memcached on your windows machine. Basically you have to install the same memcache executable as many times as you want servers.

Installing memcache from the command line is simple:

sc create  "Memcached11211" binPath= "E:\webserver\memcached.exe -d runservice -p 11211 -m 128"  DisplayName= "Memcached11211" start= auto

Thus, for multiple instances this will be:

sc create  "Memcached11211" binPath= "E:\webserver\memcached.exe -d runservice -p 11211 -m 15"  DisplayName= "Memcached11211" start= auto
sc create  "Memcached11212" binPath= "E:\webserver\memcached.exe -d runservice -p 11212 -m 15"  DisplayName= "Memcached11212" start= auto
sc create  "Memcached11213" binPath= "E:\webserver\memcached.exe -d runservice -p 11213 -m 15"  DisplayName= "Memcached11213" start= auto
sc create  "Memcached11214" binPath= "E:\webserver\memcached.exe -d runservice -p 11214 -m 15"  DisplayName= "Memcached11214" start= auto
sc create  "Memcached11215" binPath= "E:\webserver\memcached.exe -d runservice -p 11215 -m 15"  DisplayName= "Memcached11215" start= auto
sc create  "Memcached11216" binPath= "E:\webserver\memcached.exe -d runservice -p 11216 -m 15"  DisplayName= "Memcached11216" start= auto
sc create  "Memcached11217" binPath= "E:\webserver\memcached.exe -d runservice -p 11217 -m 15"  DisplayName= "Memcached11217" start= auto
sc create  "Memcached11218" binPath= "E:\webserver\memcached.exe -d runservice -p 11218 -m 15"  DisplayName= "Memcached11218" start= auto
sc create  "Memcached11219" binPath= "E:\webserver\memcached.exe -d runservice -p 11219 -m 15"  DisplayName= "Memcached11219" start= auto
sc create  "Memcached11220" binPath= "E:\webserver\memcached.exe -d runservice -p 11220 -m 15"  DisplayName= "Memcached11220" start= auto
sc create  "Memcached11221" binPath= "E:\webserver\memcached.exe -d runservice -p 11221 -m 15"  DisplayName= "Memcached11221" start= auto
sc create  "Memcached11222" binPath= "E:\webserver\memcached.exe -d runservice -p 11222 -m 15"  DisplayName= "Memcached11222" start= auto

As you can see from the example above, you have to choose a different port for each memcache instance you are running.
