为php安装memcached扩展笔记

1、下载libmemcached库 地址在https://code.launchpad.net/libmemcached

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz

2、下载php memcached扩展，地址在http://pecl.php.net/package/memcached

wget http://pecl.php.net/get/memcached-2.2.0.tgz

3、解压

[root@localhost solf]# tar xzf libmemcached-1.0.18.tar.gz 
[root@localhost solf]# tar xzf memcached-2.2.0.tgz

4、安装libmemcached

[root@localhost libmemcached-1.0.18]# ./configure --prefix=/usr/local/libmemcached --with-memcached

[root@localhost libmemcached-1.0.18]# make && make install

5、安装PHPmemcached扩展

运行phpize命令生成configure配置文件

[root@localhost memcached-2.2.0]# /usr/local/php/bin/phpize 
Configuring for:
PHP Api Version:         20090626
Zend Module Api No:      20090626
Zend Extension Api No:   220090626

安装，因为机子上可能没有sasl，这里暂时不启用，加上参数--disable-memcached-sasl，否则--enable-sasl

[root@localhost memcached-2.2.0]# ./configure --with-php-config=/usr/local/php/bin/php-config --disable-memcached-sasl

make && make install

到些安装完成

6、配置php，加载memcahed扩展

extension=memcached.so

7、重启httpd

[root@localhost no-debug-non-zts-20090626]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd:                                            [  OK  ]

8、查看phpinfo
