Introduction to distributed cache BeIT Memcached

Maybe you haven't used the distributed cache. In the case of a web Cluster, it can make some common data resident in the server memory without worrying about the non-synchronization of various web servers.
The following is a brief introduction to beitmemcached's support for. net. For more information, see
Http://code.google.com/p/beitmemcached/

A complete procedure:
1. Click downloads on the webpage to download the memcached_1.2.5.zip and beitmemcached_source_2008_05_31.zip packages.
2. Decompress memcached_1.2.5.zip, which is the server side of memcached.
3. Copy Memcached_1.2.5 to the computer you specified as the cache server, for example, 192.168.0.1.
4. Run the command 'd: \ memcached \ memcached.exe-d install' in cmd to install the server. At this time, it should appear in the windows service.
5. Run the command 'd: \ memcached \ memcached.exe-d start' in cmd to start the service and check whether the memcached process exists in the server process.
6. Check whether port 11211 of the server is enabled (in firewall settings). Otherwise, the server cannot be accessed by other machines.
7. The server has been installed and tested on other machines. Run cmd to telnet 192.168.0.1 11211 to check whether the server can log on.

8. Decompress beitmemcached_source_2008_05_31.zip. It is a client developed by. net 2.0. It contains all the source code and a call example.
9. Open the project with the corresponding version of vss. If you are interested, study the code slowly. If you are not interested, generate a class library and compile a BeITMemcached. dll file.
10. Create a console program, reference BeITMemcached. dll, and enter similar code for testing.

Using System; <br/> using BeIT. memCached; <br/> namespace ConsoleApplication3 <br/>{< br/> class Program <br/>{< br/> static void Main (string [] args) <br/>{< br/> MemcachedClient. setup ("TestCache", new string [] {"192.168.0.1"}); <br/> MemcachedClient cache = MemcachedClient. getInstance ("TestCache"); <br/> cache. sendReceieveTimeout = 5000; <br/> cache. minPoolSize = 1; <br/> cache. maxPoolSize = 5; <br/> cache. set ("jinjazz", "Scissors"); <br/> object obj = cache. get ("jinjazz"); <br/> Console. writeLine (obj); <br/> Console. read (); <br/>}< br/>}

A distributed cache example is as simple as operating hashtable.

11. Check the cache running status. You need to be familiar with some basic memcached commands.
Enter telnet 192.168.0.1 11211 on your machine to enter telnet
