redis超时与predis

Question

我正在使用带有php的redis(在http://github.com/nrk/predis/上使用),并且经常出现超时.堆栈跟踪显示:

[04-Apr-2010 03:39:50] PHP Fatal error:  Uncaught exception 'Predis_ClientException' with message 'Connection timed out' in redis.php:697
Stack trace:
#0 redis.php(757): Predis_Connection->connect()
#1 redis.php(729): Predis_Connection->getSocket()
#2 redis.php(825): Predis_Connection->writeCommand(Object(Predis_Commands_ListRange))
#3 redis.php(165): Predis_ConnectionCluster->writeCommand(Object(Predis_Commands_ListRange))
#4 redis.php(173): Predis_Client->executeCommandInternal(Object(Predis_ConnectionCluster), Object(Predis_Commands_ListRange))
#5 redis.php(157): Predis_Client->executeCommand(Object(Predis_Commands_ListRange))
#6 [internal function]: Predis_Client->__call('lrange', Array)

这种情况一直发生,我不明白为什么.任何人有任何想法？

Answer 1

我认为这是因为Redis默认关闭空闲连接.

redis.conf

# Close the connection after a client is idle for N seconds (0 to disable)
timeout 0
