centos 安裝php Memcache 環境

Linux指令下載：

wget http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz

wget http://www.monkey.org/~provos/libevent-2.0.20-stable.tar.gz

wget http://pecl.php.net/get/memcache-3.0.7.tgz

上面是安裝。php  Memcache 環境的必須的3個包

1、先安裝libevent

tar zxvf libevent-2.0.20-stable.tar.gz 
cd libevent-2.0.20-stable 
./configure --prefix=/usr 
make && make install

whereis libevent 查看軟件安裝路徑

檢測一下查看是否安裝:

ls -al /usr/lib | grep libevent
#顯示
libevent.so -> libevent-2.0.so.5.1.2

2.安裝Memcache

tar -zxvf memcached-1.4.0.tar.gz
cd memcached-1.4.0.tar.gz
./configure --with-libevent=/usr/
make && make install

檢測是否成功安裝

ls -al /usr/local/bin/mem*
#顯示
/usr/local/bin/memcached


memcached -d -u root
#無提證明開啓成功

3.安裝Memcache的PHP擴展

tar vxzf memcache-3.0.7.tgz
cd memcache-3.0.7
/usr/local/php/bin/phpize
./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir
make && make install

添加一行來載入memcache擴展：

在php.INI  添加

extension=memcache.so

測試：

<?php
$mem = new Memcache;   
$mem->connect("127.0.0.1", 11211);   
$mem->set('key','This is key!<br>', 0, 60);   
echo "設置緩存成功<br>";   
$val = $mem->get('key');   
echo $val;
