2         M64 = -m64
3         LIBS = /usr/lib64/libevent.so /usr/lib64/libm.so
4 else
5         LIBS = -levent -lm -L/usr/local/libevent/lib

5 #define _KETAMA_H
6 ..........

3-3.安裝memagent

 1 make 2 ln -i /usr/local/magent/magent /usr/bin/magent 

4. 使用memagent

1 #memcached 啟動
2 memcached -d -m 10240 -u root -c 30720 -p 11211 -P /tmp/memcached.pid
3 #magent 啟動
4 magent -u root -n 102400 -p 12000 -s 192.168.0.1:11211 -s 192.168.0.2:11211
