大家好，又见面了，我是全栈君。
1.查memcache状态 /usr/bin/perl /usr/local/src/memcached-1.4.5/scripts/memcached-tool localhost:11211 或者 telnet localhost 11211
2.手动清除memcached测试
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). 重启memcached进程 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 = new Memcache; $memcache_obj->connect(‘memcache_host’, 11211); $memcache_obj->flush(); ?>
这个测试的表现是请求Memcache::flush()以后仍可以get $key取到值,而且通过memcached-tool 查到该item的max_age并无变化.
