Memcached

您可以在Wikipedia上了解到此条目的英文信息 Memcached Thanks, Wikipedia.

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

安装

./configure; make; make install
/usr/local/bin/memcached -m 300 -l 127.0.0.1 -p 11211 -d -u root 

可能需要 export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

/usr/local/bin/memcached -m 300 -l 127.0.0.1 -p 11211 -d -u root -P /var/run/memcached.pid -c 128 -vv 选项 说明

• -p 使用的TCP端口。默认为11211
• -m 最大内存大小。默认为64M
• -vv 用very vrebose模式启动，调试信息和错误输出到控制台
• -d 作为daemon在后台启动
• -c 最大运行的并发连接数，默认是1024，按照服务器的负载量来设定
• -P 设置保存Memcache的pid文件
• -l 监听的服务器IP地址，如果有多个地址的话
• -u 运行Memcache的用户，默认不能用root启动，所以当前用户为root用户时，需要用-u参数来指定

Twitter Cache

• http://twitter.com/ Twitter中间业务层件使用了Memcached
• Fotolog.com - the world's largest photo blogging community

we introduced memcache, creating a distributed 30-server cluster with 4 gigs available in total and made a very minor code mod to use memcache, and our peak period load times dropped back down to the 2 second or so range.
