When I install the nginx and memcached, there is an error: 404 not found.
If commenting: memcached_pass IP:11211, the error is gone.
The configure file of my nginx is as follows:

worker_processes 1;
4 daemon off;
5 master_process off;
6 #error_log logs/error.log;
7 #error_log logs/error.log notice;
8 #error_log logs/error.log info;
