Test Memcached service http://www.linuxidc.com/Linux/2012-08/69316.htm on Ubuntu and Windows

Many large load sites around the world use Memcache as a cache service to share the pressure on database servers.

Memcache is the project name and memcached is the service name. It makes a lot of new contacts feel inexplicable. I personally think it is more correct to use the former.

Like database development, Memcache is divided into two parts: Memcache server and client. The Memcache server runs as a Service. The creation, storage, and deletion of all data caches are actually completed here. Client, here we refer to extensions that can be called by PHP, C, and Java applications.

Installation on Ubuntu:

Sudo apt-get installmemcached

After the installation, memcached will be automatically started. Listen on port 11211 and check the command ps-ef | grep memcached.

After installing the Memcache server, we need to specify the parameter to start the service:

Memcached-d-m 128-p 11111-u root

Here we need to describe the memcached service startup parameters:

-P listening port
-L connected IP address. The default value is local
-D start: start the memcached service.
-D restart: restart the memcached service.
-D stop | shutdown the running memcached Service
-D install the memcached Service
-D uninstall memcached Service
-U runs as the identity (only valid when running as root)
-MB maximum memory usage, in MB. The default value is 64 MB.
-An error is returned when M memory is used up, instead of deleting items.
-C: Maximum number of simultaneous connections. The default value is 1024.
-F block size growth factor. The default value is 1.25-n. The minimum allocation space is 48 for key + value + flags.
-H Show Help

Remember to modify the parameters:

/Etc/memcached. conf andsearch-L 127.0.0.1And replace it-L 0.0.0.0
