Memcached does not allow Internet access

By default, memcached installed in lnmp can be accessed from the Internet. It is not used on the Internet for my small website, so it can only be used on the Intranet. Modify the VI/etc/init. d/memcached File

Port = 11211
User = root
Maxconn = 1024
Cachesize = 32
Options = ""
IP = 127.0.0.1

Retval = 0
Prog = "memcached"

Start (){
Echo-N $ "Starting $ prog :"
Memcached-d-L $ IP-P $ port-U $ user-M $ cachesize-C $ maxconn-P/var/run/memcached. PID $ options
Retval =$?
Echo
[$ Retval-EQ 0] & Touch/var/lock/subsys/memcached
}

If iptables is installed, you can use iptables to disable Internet access.
