c) ./configure �Cprefix=/usr/local/libmemcached �Cwith-memcached=/usr/bin/memcached
d) Make
e) Make install
f) echo “/usr/local/libmemcached”>>/etc/ld.so.conf
g) ldconfig
h) tar zxvf memcached_functions_mysql-0.9.tar.gz
i) cd memcached_functions_mysql-0.9
j) ./configure �Cprefix=/usr/local/memcache_mysql �Cwith-mysql=/usr/local/mysql/bin/mysql_config �Cwith-libmemcached=/usr/local/libmemcached
k) Make && make install
l) Mkdir /usr/local/mysql/lib/mysql/plugin
m) Cp /usr/local/memcache_mysql/lib/libmemcached_functions* /usr/local/mysql/lib/mysql/plugin
n) Chown �CR mysql:mysql /usr/local/mysql/lib/mysql/plugin
o) /usr/local/mysql/bin/mysql �Curoot �Cp123456 mysql
p) Mysql>source /opt/memcached_functions_mysql-0.9/sql/install_functions.sql
q) Mysql>select * from mysql.func
三、测试
a) Mysql>select memc_servers_set(‘127.0.0.1 11211’);
b) Mysql>use test;
c) Mysql>create table t_1(id int ,name varchar(20));
d) Mysql>create trigger trigger_t_1add after insert on t_1 for each row set @tmp=memc_set(NEW.id,NEW.name);
e) Mysql>create trigger trigger_t_1update after update on t_1 for each row set @tmp=memc_set(NEW.id,NEW.name);
f) Mysql>Create trigger trigger_t_1del before delete on t_1 for each row set @tmp=memc_delete(OLD.id)
g) Mysql>Insert into t_1 values(7,’555555’),(3,’33333333’) ,(8,’ 888888888’) ,(9,’ 99999999999’);
h) Mysql>update t_1 set name=’update’ where id=1
i) Mysql>delete from t_1 where id=1;
j) Mysql>exit
k) telnet 127.0.0.1 1121
get 8
VALUE 8 0 9
888888888
END
get 9
VALUE 9 0 11
99999999999
END
get 7
VALUE 7 0 6
555555
END
