[背景] Twitter 开源了他们自己用的一个 Apache 模块 mod_memcache_block (a distributed IP blocking system),这个模块根据 HTTP 代码请求限制访问频率。上周我装了下mod_memcache_block,出了很多错误,今天把它记录下来,供网上需要的朋友学习。 [过程] 下面的installation,是说明文档中的,不够详细,不过,放到前面供参考. INSTALLATION 1. Install libmemcached-0.25 or better. 2. Install memcached-1.2.6 3. Edit the Makefile to indicate the location of libmemcached 4. Type "make", then "make install" 5. Update your apache configuration 6. Restart the server with apachectl restart 下载 wget http://download.tangent.org/libmemcached-0.25.tar.gz wget http://memcached.googlecode.com/files/memcached-1.2.6.tar.gz

对比Memcached和Redis,谁才是适合你的缓存?

Memcached vs Redis 近期公司采购软件,评估时,某软件谈到使用了 Memcached 和 Redis 缓存。在本文中,将研究这两个流行的缓存的异同,方便理解和记忆。 1. Memcached 与 Redis 通常,我们会考虑在处理大量数据时使用** 缓存 提高性能。** Memcached 是一个分布式内存缓存系统,设计简单易用,非常适合用作缓存或会话存储。 Redis 是一个内存中的数据结构存储,它提供了一系列丰富的特性。它作为缓存、数据库、消息代理和队列非常有用。 2. 安装 2.1. 安装 Memcached 下载最新版的 Memcached 包并执行make进行安装 : $ wget http://memcached.org/latest $ tar -zxvf memcached-1.6.3.tar.gz $ cd memcached-1.6.3 $ ./configure && make && make test && sudo make install 2.2. 安装 Redis 相似的, 安装最新版本的 Redis server : $ wget http://download.redis.io/releases/redis-5.0.8.tar.gz $ tar xzf redis-5.0.8.tar.gz $ cd redis-5.0.8 $

PHP扩展memcached、memcache对比-2019.05.11

###背景 此文是之前开发过程中,出于对版本更新的疑问,以及新版本解决了什么问题的一个回答,简单总结交流。 我们在业务中广泛使用memcache做缓存,我们都了解memcached本身不支持分布式,业务上会使用客户端分布式算法(一致性hash)保证分布式缓存集群性能和可用性。客户端将多个mc实例维护成一个缓存池,根据缓存key值进行一致性hash计算,写入具体指定的hash节点。由于单机可用性无法保证,若要体现此mc集群的高可用,对于单点故障机器的剔除就十分重要。但目前框架内使用的memcached扩展(也是行业内一致推荐的扩展)却没能很好的完成这一功能(或者是设置上没有正确设置),当集群中一个实例挂掉之后,hash到这台机器上的set、get方法全部失效,没有保证集群的可用。而memcache扩展在出现单节点挂掉的情况下,会把key路由到新的alive节点上,保证集群的可用性。那么问题就来了,为什么在更“新”,更“先进”的memcached扩展内却没有完成如此好特性?是有坑?还是实现上会有问题?值得深究一番。 ###参考资料 《memcached - PHPClientComparison.wiki》 《Memcache 和 Memcached 客户端的区别》 《Memcached集群/分布式的单点故障》 ###正文 几篇博文里都说memcache有缺陷,总结一下核心缺陷:

Persistent memcached in PHP - server pool growing until curr_connections 10

馋奶兔 提交于 2019-12-11 02:28:56
问题 I have a problem with Memcached persistence in PHP. Memcached lib returns empty getServerList() until there are 10 concurrent connections. Couldn't find sensible explanation of that, but found people with the same problem (without solution). My example: class Cache { protected $memcached; public function __construct($cache_name) { $instance_name = 'persistent-' . $cache_name; $this->memcached = new Memcached($instance_name); $server_count = count($this->memcached->getServerList()); echo '[MC]
