Distributed Cache Beit Memcached Introduction

Perhaps you have not used distributed cache, in the case of a Web cluster, it can be very good for some of the common data Resident server memory without worrying about the different steps of the web.
Here's a little bit about beitmemcached support for. NET, official reference
http://code.google.com/p/beitmemcached/

A complete sequence of operations:
1, click on the page above the downloads, put Memcached_1.2.5.zip and beitmemcached_source_2008_05_31.zip two compression package down.
2, decompression Memcached_1.2.5.zip, it is the server side of memcached.
3. Copy the memcached_1.2.5 to the computer you specified as the cache server, for example, called 192.168.0.1.
4, cmd run similar command ' d:\memcached\memcached.exe-d Install ' installation Server side, this time it should appear in the Windows service
5, cmd run similar command ' d:\memcached\memcached.exe-d start ' to start the service, see if there is a memcached process in the server process.
6. Confirm that server port 11211 is open (in firewall settings), otherwise the machine cannot access
7, the server side has been installed at this time, testing on other machines, cmd input telnet 192.168.0.1 11211 see if you can log in.

8. Unzip Beitmemcached_source_2008_05_31.zip, which is a client developed by. NET 2.0, which is full of source code and an example of invocation.
9, with the corresponding version of the VSS open the project, if interested in slowly study the code, not interested in choosing to generate a class library, compile a BeITMemcached.dll out.
10, create a new console program, reference BeITMemcached.dll, enter similar code test

Using System;
Using Beit.memcached;
Namespace ConsoleApplication3
{
    Class Program
    {
        static void Main (string[] args)
        {
            Memcachedclient.setup ("Testcache", new string[] {"192.168.0.1"});
            Memcachedclient cache = memcachedclient.getinstance ("Testcache");
            Cache. Sendreceievetimeout = 5000;
            Cache. Minpoolsize = 1;
            Cache. Maxpoolsize = 5;
            Cache. Set ("Jinjazz", "scissors");
            Object obj = cache. Get ("Jinjazz");
            Console.WriteLine (obj);
            Console.read ();
        }
    }
}

An example of a distributed cache is just as easy as operating Hashtable.

11, check the cache running state, this you need to be familiar with some memcached basic commands
Enter Telnet 192.168.0.1 11211 on your machine first, enter Telnet
Input stats in the dark, will come out the following results, may be useful to you I added a comment
STAT PID 2928
STAT Uptime 139279

12, the end.
