. net/c# memcached installation and basic use

: memcached Windows 64-bit

1, extract to the specified directory, such as: D:\Memcached\memcached-win64-1.4.4-14.
2, open the command window with CMD, go to the extracted directory, enter "memcached.exe-d install".
3, open the Control Panel, open the service, you can see memcached already on the above can, if not started, then manually start.

4. Use the Telnet command to verify that the cache server is available.

Telnet 10.1.19.61 11211

Start with nothing to show, enter after the command stats to view statistics, such as, the server is functioning properly.

Three, the parameter introduction

1, the above installation and start are in the default environment, in the installation can set the following parameters:
-P Listening Port
-L connected IP address, default is native
-D Start memcached service
-D Restart Restart memcached service
-D Stop|shutdown Close the running memcached service
-D Install memcached service
-d Uninstall Uninstall memcached service
-U Run as (only valid when running as root)
-m maximum memory usage, in megabytes. Default 64MB
-M running out of memory and returning an error instead of deleting an item
-c Maximum number of simultaneous connections, default is 1024
-F Block size growth factor, default is 1.25
-N Minimum allocated space, key+value+flags default is 48
-H Display Help
