昨天晚上编译了新的PHP7.2而忘记备份PHP.INI与www.conf,于此引发了一个严重的问题,以前设置的优化参数失效,而导致网页严重卡顿。

解决方法:

#/etc/php/php7.2/mods-available vim memcache.ini ; uncomment the next line to enable the module extension=memcache.so [memcache] ; Whether to transparently failover to other servers on errors. ; ; memcache.allow_failover="1" ; Defines how many servers to try when setting and getting data. Used ; only in conjunction with memcache.allow_failover. ; ; memcache.max_failover_attempts="20" ; Data will be transferred in chunks of this size, setting the value ; lower requires more network writes. Try increasing this value to ; 32768 if noticing otherwise inexplicable slowdowns. ; ; memcache.chunk_size="8192" ; The default TCP port number to use when connecting to the memcached ; server if no other port is specified. ; ; memcache.default_port="11211" ; Controls which strategy to use when mapping keys to servers. Set ; this value to consistent to enable consistent hashing which allows ; servers to be added or removed from the pool without causing keys to ; be remapped. Setting this value to standard results in the old ; strategy being used. ; ; memcache.hash_strategy="consistent" ; Controls which hash function to apply when mapping keys to servers, ; crc32 uses the standard CRC32 hash while fnv uses FNV-1a ; ; memcache.hash_function="crc32" ; Use memcache as a session handler by setting this value to memcache. ; ; session.save_handler="memcache" ; Defines a comma separated of server urls to use for session storage, ; for example session.save_path="tcp://host1:11211,tcp://host2:11211". ; ; Each url may contain parameters which are applied to that server, ; they are the same as for the Memcache::addServer() method. For ; example: session.save_path="tcp://host1:11211?persistent=1&weight=1&timeout=1&retry_interval=15" ; ; session.save_path="tcp://localhost:11211" ; Additional parameters ; memcache.protocol=ascii ; memcache.redundancy=1 ; memcache.session_redundancy=2 ; memcache.compress_threshold=20000 ; memcache.lock_timeout=15 #查看是否已加载 php -m | grep memcache
Code language: PHP (php)

于此,问题结束。
