django - Lighttpd - Cannot start, can't bind port, permission denied -


i have installed lighttpd in parallel apache (using port 80). starting lighttpd gives me error 

starting lighttpd: 2013-04-05 15:56:17: (network.c.379) can't bind port:  81 permission denied

changes made in lighttpd.conf:

server.port = 81 server.use-ipv6 = "disable"

what missing here? using centos 6.3

netstat -ltp result:
