How to manually clear the memcached cache-use the memcache extension of telnet and PHP

1. check the memcache status/usr/bin/perl/usr/local/memcached/scripts/memcached-toollocalhost: 11211 or telnetlocalhost112112. manually clear memcached test 1). flush_allecho &

1. check the memcache status

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

Or

telnet localhost 11211

2. manually clear memcached test

1). flush_all

echo "flush_all" | nc localhost 11211# telnet localhost 11211Trying 127.0.0.1...Connected to localhost.localdomain (127.0.0.1).Escape character is '^]'.get var_keyVALUE var_key 0 13test variableENDflush_allOKget var_keyENDquitConnection closed by foreign host.

2) restart the memcached process.

kill $(ps aux|grep memcached|grep -v grep |awk '{print $2}')/usr/local/memcached/bin/memcached -d -m 256 -p 11211 -u nobody

3) Memcache: flush ()? Clear all caches immediately.

 connect('memcache_host',?11211);$memcache_obj->flush();?>

In this test, the value of get $ key can still be obtained after Memcache: flush () is requested, and the max_age of the item is not changed through memcached-tool.
