1. 先安装memcache php组件
wget http://pecl.php.net/get/memcache-3.0.6.tgz
tar -zxvf
memcache-3.0.6.tgz
cd
memcache-3.0.6
/usr/local/php/bin/phpize
&& ./configure --enable-memcache && make
注：会提示 php-onfig 找不到，然后加上 --with-php-config=/usr/local/php/bin/php-config
参数就可以了。
/usr/local/php/bin/phpize
&& ./configure --enable-memcache
--with-php-config=/usr/local/php/bin/php-config &&
make
cp
modules/memcache.so /usr/local/php/lib/php/extensions
注：还有一种方法也可以安装，不过我没有试过，就是执行
yum install php5-memcache
2.
修改php.ini文件
touch
/etc/php.d/memcached.ini
echo 'extension=memcache.so' > /etc/php.d/memcached.ini
注：也可以直接在php.ini
加上 extension=memcache.so 就可以了。
3.
php测试文件
<?php
$memcache = new Memcache;
$memcache->connect('localhost', 11211)
or die ("Could not connect");
$version = $memcache->getVersion();
echo "Server's version: ".$version."<br/>\n";
$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)<br/>\n";
$get_result = $memcache->get('key');
echo "Data from the cache:<br/>\n";
var_dump($get_result);
?>
4.
再附上memcached安装方法（非centos下）
#
Download & install libevent (memcached dependency)
wget http://www.monkey.org/~provos/libevent-1.4.8-stable.tar.gz
tar xfz libevent-1.4.8-stable.tar.gz
cd libevent-1.4.8-stable
./configure && make && sudo make install
# Create a symlink to libevent
sudo ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib
# Download & install memcached
wget http://danga.com/memcached/dist/memcached-1.2.6.tar.gz
tar xfz memcached-1.2.6.tar.gz
cd memcached-1.2.6
./configure && make && sudo make install
# Run memcached as a daemon (d = daemon, m = memory, u = user, l = IP to listen to, p = port)
memcached -d -m 1024 -u root -l 127.0.0.1 -p 11211
