php连接memcached

• 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_AUTOCONF environment variable. Then, rerun this script.

此时没有生成configure文件。

解决方法：

# cd /usr/src
# wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz
# tar -zvxf m4-1.4.9.tar.gz
# cd m4-1.4.9/
# ./configure && make && make install
# cd ../
# wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz
# tar -zvxf autoconf-2.62.tar.gz
# cd autoconf-2.62/
# ./configure && make && make install

或者更简单的办法是：
# yum install m4
# yum install autoconf
