安装memcached_functions_mysql，实现memcache 和mysql自动更新

mysql 5.1支持触发器以及自定义函数接口(UDF)的特性，如果配合libmemcache以及Memcached Functions for MySQL，就能够实现memcache的自动更 新。简单记录一下安装测试步骤。

安装需求：

需要安装memcached、libmemcached

1、下载memcached_functions_mysql-1.1.tar.gz
https://launchpad.net/memcached-udfs/+download
2、解压并安装memcached_functions_mysql-1.1.tar.gz

tar -xzvf memcached_functions_mysql-1.1.tar.gz

cd memcached_functions_mysql-1.1

./configure --with-libmemcached=/usr/local/

make && make install

注意

在编译的时候报错：

servers.c: In function 'memc_servers_set':

servers.c:122: error: 'memcached_st' has no member named 'hosts'

servers.c:123: error: 'memcached_st' has no member named 'hosts'

servers.c:124: error: 'memcached_st' has no member named 'hosts'

经过测试：安装了libmemcached-0.39、libmemcached-0.38都有这样的错误，libmemcached-0.37没有这种错误，你需要安装libmemcached-0.37
