以其它用户运行

./repcached -d -p 11211 –v-d

 ./repcached -p 11212 -x localhost -v -d

修改端口 

./repcached -p 11311 -d -v -X 11312
./repcached -p 11313 -x 127.0.0.1 -v -d -X 11312

./repcached -h
memcached 1.2.8

-p <num> TCP port number to listen on (default: 11211)
-U <num> UDP port number to listen on (default: 11211, 0 is off)

under sh this is done with ‘ulimit -S -l NUM_KB‘).
