/Usr/local/bin/memcached-d-m 10-u root-l 127.0.0.1-p 12000-c 256-P/tmp/memcached. pid

-D option is to start a daemon,
-M indicates the amount of memory allocated to Memcache. The unit is MB. Here I am 10 MB,
-U is the user who runs Memcache. Here I am root,
-L is the IP address of the listener server. If there are multiple IP addresses, I have specified the Server IP address 127.0.0.1.
-P is the port for Memcache listening. I have set port 12000 here, preferably port 1024 or above,
-The "c" option is the maximum number of concurrent connections. The default value is 1024. I have set 256 here, which is based on the load of your server,
-P is the pid file for saving Memcache. Here I save it in/tmp/memcached. pid,

6. Compile the test file

<?php    $mem = new Memcache;    $mem->connect( "127.0.0.1", 12000 );    $mem->set( "hi", "hello,ghostwu", 0, 120 );    echo $mem->get( "hi" ) . PHP_EOL;?>
