means to force the kill process.After the memcached is started, the data in the cache can be manipulated by the client, and we describe some common clients and how to use them.Telnet ClientThe Telnet client can use the command line to monitor how the memcached server stores data. For example, Memcached has a service address of 192.168.4.86:11211 and can telnet to the service port:Telnet 192.168.4.86 11211If the connection succeeds, you can use some of the following commands:
, Memcached is an LRU cache, and it cleans up extended data as long as it is pre-booked, but in fact, memcached does not delete any cached data but is no longer visible to the customer after it expires; Memcached also does not really clean up the cache by age, but only when the get command arrives, checking its duration;Memcached provides a handful of commands to accomplish server-side interactions, which are based on memcached protocol implementations.Storage class Commands: Set, add, replace,
