A CA file has been bootstrapped using certificates from the SystemRoots
keychain . To add additional certificates ( e . g . the certificates added in
the System keychain ) , place . pem files in
  / usr / local / etc / openssl / certs
 
and run
  / usr / local / opt / openssl / bin / c_rehash
 
openssl is keg - only , which means it was not symlinked into / usr / local ,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries .
 
If you need to have openssl first in your PATH run :
   echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' > > ~ / . bash_profile
 
For compilers to find openssl you may need to set :
   export LDFLAGS = "-L/usr/local/opt/openssl/lib"
   export CPPFLAGS = "-I/usr/local/opt/openssl/include"

Passaggio 2: verifica

Verifica che sia stato avviato correttamente.

Digita il comando ps -few | grep memcached ps -few | grep memcached .

bash - 3.2 $ ps - few | grep memcached
110048994 88258 88202    0 12 : 31PM ttys000      0 : 00.00 grep memcached

Vedrai il processo memorizzato nella cache come parte di un risultato.

Per impostazione predefinita, Memcached viene eseguito sulla port 11211 .

L'uso di brew è il modo più sicuro e semplice per installare Memcached su Mac OS X. Se brew non è installato localmente, segui l'approccio manuale di seguito.

A questo punto il tuo memcached è installato correttamente.

Il prossimo passo è start il processo memorizzato nella cache. Esegui sotto il comando e il tuo processo memorizzato nella cache verrà avviato sulla porta 12345.

bash - 3.2 $ memcached - p 12345

Buon divertimento e buona programmazione ragazzi!! Fammi sapere se riscontri problemi durante l'installazione di Memcached.

E dopo? Crea client Java molto semplici con 3 diversi approcci.

  1. Client Java Memcached che utilizza la libreria net.spy.spymemcached
  2. Client Java memorizzato nella cache utilizzando com.whalin.Memcached-Java-Client e com.googlecode.xmemcached Libraries
