4. Start memcached
#/Data/memcached/bin/memcached-D-M 1024-P 11211-u Root
/Data/memcached/bin/memcached-D-M 1024-P 11211-l 10.0.0.40-u Root
Parameter description-M specifies the number of megabytes of cache space used-l host name-P specifies the port to be listened to-u specifies the user to run

If you encounter problems when running memcached, the error prompt is as follows:
/Data/memcached/bin/memcached: Error while loading shared libraries: libevent-1.3b.so.1: cannot open shared object file: no such file or directory
Run ld_dubug = libs to know the library loading path when memcached is started. The details are as follows:
