先安装php的memcache扩展

# wget http://www.lishiming.net/data/p_w_upload/forum/memcache-2.2.3.tgz

# tar zxf memcache-2.2.3.tgz

# cd memcache-2.2.3

# /usr/local/php/bin/phpize

# ./configure --with-php-config=/usr/local/php/bin/php-config

# make && make install

安装完后会有类似这样的提示：Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/

把这个记住，然后修改php.ini，把 extension_dir = "./" 修改为extension_dir = "/usr/local/servers/php5/lib/php/extensions/no-debug-non-zts-20090626/"

或者指定新的位置，我以下是指定新的位置

并添加一行extension="memcache.so"

[root@localhost memcache-2.2.3]# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
[root@localhost memcache-2.2.3]# ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
memcache.so

[root@localhost memcache-2.2.3]# vim /usr/local/php/etc/php.ini

[root@localhost memcache-2.2.3]# ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
memcache.so

将memcache.so拷贝到/usr/local/php/ext 下

[root@localhost memcache-2.2.3]# mkdir /usr/local/php/ext #创建目录

[root@localhost memcache-2.2.3]# cp /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/memcache.so /usr/local/php/ext/

[root@localhost memcache-2.2.3]# ls !$
ls /usr/local/php/ext/
memcache.so

添加路径

[root@localhost memcache-2.2.3]# vim /usr/local/php/etc/php.ini


检测添加memcached模块是否添加成功

[root@localhost memcache-2.2.3]# /usr/local/php/bin/php -m|grep memcache
memcache

测试能否连接memcached

[root@localhost memcache-2.2.3]# curl www.apelearn.com/study_v2/.memcache.txt > 1.php 2>/dev/null

下载一个1.php文件

[root@localhost memcache-2.2.3]# /usr/local/php/bin/php 1.php
Get key1 value: This is first value<br>Get key1 value: This is replace value<br>Get key2 value: Array
(
[0] => aaa
[1] => bbb
[2] => ccc
[3] => ddd
)
<br>Get key1 value: <br>Get key2 value: <br>[root@localhost memcache-2.2.3]#

[root@localhost memcache-2.2.3]# /usr/local/php/bin/phpize

Configuring for:
PHP Api Version: 20090626
Zend Module Api No: 20090626
Zend Extension Api No: 220090626
Cannot find autoconf. Please check your autoconf installation and the

$PHP_AUTOCONFenvironmentvariable.Then,rerunthisscript.

此时没有生成configure文件。

解决方法：

#cd/usr/src#wgethttp://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz#tar-zvxfm4-1.4.9.tar.gz#cdm4-1.4.9/#./configure&&make&&makeinstall#cd../#wgethttp://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz#tar-zvxfautoconf-2.62.tar.gz#cdautoconf-2.62/#./configure&&make&&makeinstall

或者更简单的办法是：#yuminstallm4#yuminstallautoconf
