在php上
加載memcache.so（使php作為memcache的客戶端）
tar zxf memcache-3.0.8.tgz
cd memcache-3.0.8/
/usr/local/php/bin/phpize
./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config
make && make install
注意：安裝完后會(huì)有類似這樣的提示： Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20131226/；記住這個(gè)路徑，需要加載到php的配置文件中。
vim /etc/php.ini
##查找extension并在對(duì)應(yīng)位置添加
extension=/usr/local/php/lib/php/extensions/no-debug-zts-20131226/memcache.so
##在末尾添加
session.save_handler = memcache
session.save_path = “tcp://192.168.154.131:11211?persistent=1&weight=1&timeout=1&retry_interval=15”
service php-fpm restart
在nginx上
編寫(xiě)php測(cè)試頁(yè)面。vim /usr/local/nginx/html/index.php
<?php
phpinfo();
?>
訪問(wèn)http://192.168.154.132，應(yīng)當(dāng)可以看到memcache和session字樣。
（成功表示php上安裝好了memcache.so）
編寫(xiě)memcache測(cè)試頁(yè)面。vim /usr/local/nginx/html/test.php
<?php
$memcache = new Memcache;
$memcache->connect(‘192.168.154.131’, 11211) or die (“Could not connect”);
$version = $memcache->getVersion();
echo “Server’s version: “.$version.”
“;
$tmp_object = new stdClass;
$tmp_object->str_attr = ‘test’;
$tmp_object->int_attr = 123;
$memcache->set(‘key’, $tmp_object, false, 10) or die (“Failed to save data at the server”);
echo “Store data in the cache (data will expire in 10 seconds)
“;
$get_result = $memcache->get(‘key’);
echo “Data from the cache:
“;
var_dump($get_result);
?>
預(yù)計(jì)會(huì)輸出四行字符，有memcache版本信息等
（成功表示連接到了memcache服務(wù)器）
編寫(xiě)測(cè)試memcache的session共享腳本，vim /usr/local/nginx/html/session.php
<?php
session_start();
if (!isset($_SESSION[‘session_time’]))
{
$_SESSION[‘session_time’] = time();
}
echo “now_time:”.time().”
“;
echo “session_id:”.session_id().”
“;
?>
預(yù)計(jì)輸出session_time、now_time、session_id
使用telnet連接memcache
telnet 192.168.154.131 11211
然后get session_id的值，如果得到的session_time和網(wǎng)頁(yè)上的一樣表示session共享成功。
在mysql上
mysql> create database testdb1;
mysql> use testdb1;
mysql> create table test1(id int not null auto_increment,name varchar(20) default null,primary key (id)) engine=innodb auto_increment=1 default charset=utf8;
mysql> insert into test1(name) values (‘tom1’),(‘tom2’),(‘tom3’),(‘tom4’),(‘tom5’);

在nginx上
編輯memcache緩存mysql測(cè)試頁(yè)面，vim /usr/local/nginx/html/test_db.php

echo “<br>”;
echo “name is <b><font color=#FF0000>$a[name]</font></b>”;

預(yù)計(jì)會(huì)輸出memcache的key，和我們?cè)趍ysql創(chuàng)建的數(shù)據(jù)表的數(shù)據(jù)
（成功即表示memcache緩存到mysql的數(shù)據(jù)）
