## Centos6.5下安装memcached以及php的memcached扩展,并整合到Thinkphp中 ##

### 一：首先搭建memcached服务器 ###

1. 查询资源库是否存在memcahched：yum searchmemcached

![70][]

2. memcached安装：由于不是root用户固命令为：sudo yum -y installmemcached

![70 1][]

3. 查看是否安装成功:memcached -h，出现如下，说明安装成功

![70 2][]

4. 配置memcached：vi/etc/sysconfig/memcached

![70 3][]

5. 设置不同级别下的开机启动：chkconfig--level 2345 memcached on

![70 4][]

6. 开启memchached服务：sudoservice memcached start，并查看运行状态：

memcached-tool 127.0.0.1:11211 stats

![70 5][]

### 二．安装php的memcache扩展 ###

1.打开pecl.php.net网站，去里面搜索memcache相关扩展，里面也有memcached的

![70 6][]

2.点开memcache，我这里用的是2.2.7版本，找到链接下载，使用命令：

wgethttp://pecl.php.net/get/memcache-2.2.7.tgz

![70 7][]

![70 8][]

3.解压文件 ：tar -zxvfmemcache-2.2.7.tgz

![70 9][]

4.进入目录：cd  memcache-2.2.7，并查找phpize命令所在目录，直接在本目录中执行：/usr/local/php/bin/phpize，运行后会多出些文件：

![70 10][]

![70 11][]

5.配置：./configure--with-php-config=/usr/local/php/bin/php-config

![70 12][]

6.编译，运行：make &&make install

### 三．安装php的memcached扩展 ###

说明：

安装memcached扩展，要比memcache多一步，首先安装libmemcached

1.下载：

wget [http://launchpad.net/libmemcached/1.0/1.0.9/+download/libmemcached-1.0.9.tar.gz][http_launchpad.net_libmemcached_1.0_1.0.9_download_libmemcached-1.0.9.tar.gz]

解压：tar -zxvf  libmemcached-1.0.9.tar.gz

http://xg2007524.blog.51cto.com/869106/1103023

2.cd libmemcached-\-1.0.9.tar.gz

3../configure –with-memcached

4.编译安装：make && make install

5.同上下载安装memcached扩展

下载：wget [http://pecl.php.net/get/memcached-2.2.0.tgz][http_pecl.php.net_get_memcached-2.2.0.tgz]

解压：tar -zxvf memcached-2.2.0.tgz

6.进入cdmemcached-2.2.0.tgz，执行:/usr/local/php/bin/phpize

![70 13][]

6.配置：./configure--enable-memcached --with-php-config=/usr/local/php/bin/php-config--with-libmemcached-dir=/usr/local/libmemcached/include/libmemcached

![70 14][]

7.编译安装：make &&make install

8.现在开始编辑php配置文件：vim/etc/php.ini,文件里加上三句：

extension\_dir ="/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226"//扩展库路径

extension=memcache.so //扩展名字，这是我们前面刚安装的memcache扩展

extension=memcached.so //这是memcached的扩展

![70 15][]

9.重启服务：

a)：关闭nginx服务：sudo /usr/local/nginx-1.8.0/sbin/nginx-s stop

b)：关闭php-fpm服务：kill allphp-fpm

（如何此命令关不了，就查找进程号kill掉：sudo netstat -anp |grep php）

c)：**开启php-fpm：sudo /usr/local/php/sbin/php-fpm -c /etc/php.ini -y                                        /usr/local/php/etc/php-fpm.conf**（将php.ini配置里面的最新数据重新加载进来）

d)：启动nginx服务：sudo/usr/local/nginx-1.8.0/sbin/nginx

10.测试：

代码示例：

<?php

$memcache = new Memcache;

$memcache->connect('182.92.196.241', 11211) or die ("Could notconnect");

$key = md5('www.emule.com');

$cache\_result = array();

$cache\_result = $memcache->get($key);

if($cache\_result)\{

//那我们直接取出缓存的内容就可以了

$demos\_result=$cache\_result;

echo "I got thecache<br/>";

\} else \{

$demos\_result =array("a","b","c");

echo "This is thefirst time visited, no cache<br/>";

$memcache->set($key,$demos\_result, MEMCACHE\_COMPRESSED, 1200);

foreach($demos\_result as$row)\{

echo$row."<br/>";

### 四．Thinkphp的memcache缓存配置 ###

1.在项目的配置文件里加上memcache配置项

![70 16][]

2.示例代码测试：

![70 17][]

3.打开本机命令窗口，telnet查看服务器内存 “test” 数据，出现数据表示成功：

![70 18][]

cmd ：telnet 182.92.196.24111211

![70 19][]

![70 20][]
