ubuntu环境 mysql memcached udf 完整装配

memcached udf的安装，编译安装时出现各种报错，主要是各版本的不兼容引起的。

最后成功安装，以下是安装好的各种版本，按照安装顺序如下

mysql-5.5.21.tar.gz

libevent-2.0.17-stable.tar.gz

memcached-1.4.13.tar.gz

libmemcached-0.34.tar.gz

memcached_functions_mysql-1.1?

mysql安装见?http://asyty.iteye.com/blog/1442503

?

安装memcached必须先安装libevent

?

安装libevent

?

tar -zvxf libevent-2.0.17-stable.tar.gz?

?

cd libevent-2.0.17-stable

?

./configure –prefix=/usr

?

make && make install

?

查看是否安装成功 ls /usr/lib | grep libevent

?

安装memcached

tar -zxvf memcached-1.4.13.tar.gz?

cd?memcached-1.4.13

./configure –prefix=/usr/local/ –with-libevent=/usr

?

make &&?make install

?

查看是否安装成功?ls /usr/local/bin/ | grep memcached

?

尝试启动memcached

/usr/local/bin/memcached -d -m 10 -u root -l 127.0.0.1 -p 20000 -c 256 -P tmp/memcached.pid

?

telnet连接20000端口，查看memcached 状态

telnet?127.0.0.1 ?20000

//出现以下的信息

Trying 127.0.0.1…

Connected to 127.0.0.1.

输入 stats 查看状态信息

安装libmemcached

要使用udf，必须安装libmemcached，这个比较恶心，尝试了很多很多版本，从0.38~最新的1.04，后面安装
memcached_function_mysql均出现各种不同的报错，例如?

servers.c:263:28: error: ‘memcached_st’ has no member named ‘hosts’servers.c:264:28: error: ‘memcached_st’ has no member named ‘hosts’

最后使用0.34版，据说0.37 0.36等等也没问题（后来试了下0.37编译没问题，但是和memcached_functions_mysql-1.1后面会出问题）

tar -zxvf libmemcached-0.34.tar.gz

cd libmemcached-0.34

./configure –with-memcached=/usr/local/bin/memcached

make && make install

安装 memcached_function_mysql

tar -zxvf memcached_functions_mysql-1.1.tar.gz?

cd memcached_functions_mysql-1.1

./configure –prefix=/usr/local/memcached_mysql –with-mysql=/usr/local/mysql/bin/mysql_config –with-libmemcached=/usr/local

//指定lib
