As an excellent out-of-process cache, Memcache is often used in high concurrency system architectures. Here to talk about how to use the Telnet tool to view the Memcache health and its key management maintenance. Suppose memcache installation directory:/usr/local/memcached 1, start memcache Copy Code code as follows: [Root@localhost ~]#/usr/local/memcached/bin/memcached-d-M 512-u root-l 192.168.119.70-p 12000-c 512-p/usr/local/ Memca

Memcache implementation data storage The so-called client installation means PHP (or other programs, memcache and other good API interface) to use the server-side memcache provided functions, the need for PHP to add extensions. PHP's Memcache Copy Code code as follows: Connection $mem = new Memcache; $mem->connect ("192.168.0.200", 12000); Save data $mem->set (' key1 ', ' This is ', ' 0, 60 '); $val = $mem->get (' Key1 '); ec
