手動清除memcached緩存

軟件版本

memcached-1.4.5

memcache-3.0.5

php-5.2.11

1.查memcache狀態(tài)

/usr/bin/perl /usr/local/src/memcached-1.4.5/scripts/memcached-tool localhost:11211

或者

telnet localhost 11211

2.手動清除memcached測試

1). flush_all

echo "flush_all" | nc localhost 11211

# telnet localhost 11211

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

get var_key

VALUE var_key 0 13

test variable

END

flush_all

OK

get var_key

END

quit

Connection closed by foreign host.

2). 重啟memcached進程

kill $(ps aux|grep memcached|grep -v grep |awk '{print $2}')

/usr/local/memcached/bin/memcached -d -m 256 -p 11211 -u nobody3)Memcache::flush() immediately invalidates all

existing items.

/*?procedural?API?*/$memcache_obj=memcache_connect('memcache_host',11211);memcache_flush($memcache_obj);/*?OO?API?*/$memcache_obj=?newMemcache;$memcache_obj->connect('memcache_host',11211);$memcache_obj->flush();?>這個測試的表現(xiàn)是請求Memcache::flush()以后仍可以get $key取到值,而且通過memcached-tool 查到該item的max_age并無變化.參考鏈接MicrosoftInternetExplorer402DocumentNotSpecified7.8Normal0

理解?Memcache?的服務器端與客戶端
