#重新启动php-fpm

#测试memcached连接功能
#----php测试脚本
<?php
 #phpinfo();
 $mem=new Memcache;
 $mem->connect("127.0.0.1",11211);
 $version=$mem->getVersion();
 echo "Server's version:".$version."<br>\\n";
 $mem->set("testkey","helloworld",0.600);
 echo "Store data in the cache</br>";
 $get_result=$mem->get("testkey");
 echo "The Result is:$get_result.";
?>
#----php测试脚本

配置PHP将会话保存至memcached中

#编辑/etc/php.ini，添加以下两行
session.save_handler = memcache
session.save_pah = "tcp://localhost:11211?persistent=1&weight=1timeout=1&retry_interval=15"
#测试页面--testphpsession.php
<?php
  session_start();
  if (!isset($_SESSION['www.tye.com'])) {
    $_SESSION['www.tye.com'] = time();
  }
  print $['www.tye.com'];
  print "<br><br>";
  print "Session ID:" .session_id();
?>
#测试页面--showphpsession.php
<?php
  session_start();
  $memcache_obj=new Memcache;
  $memcache_obj->connect('127.0.0.1',11211);
  $my_session=session_id();
  var_dump($memcache_obj->get($my_session));
  $memcache_obj->close();
