linux下php安装memcached扩展

以下大部分是参考的网上一些文章，但是不少文章有些坑，特意总结一下，希望能让大家少走一些弯路。

1、安装memcached

直接使用yum安装

yum -y install memcached

2、安装libmemcached

注意：--with-memcached这个选项一定要加上

cd /usr/local/src
wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
tar zxvf libmemcached-1.0.18.tar.gz
cd libmemcached-1.0.18
./configure --prefix=/usr/local/libmemcached --with-memcached
make && make install

3、安装php-fpm的memcached扩展

cd /usr/local/src
wget http://pecl.php.net/get/memcached-2.2.0.tgz
tar zxvf memcached-2.2.0.tgz
cd memcached-2.2.0
/usr/local/php/bin/phpize --with-php-config=/usr/local/php/bin/php-config
./configure --with-php-config=/usr/local/php/bin/php-config \ 
--with-libmemcached-dir=/usr/local/libmemcached --disable-memcached-sasl
make && make install

编译成功后如下所示：

Build complete.
Don't forget to run 'make test'.

Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/

4、配置php.ini文件

打开 php.ini 文件，添加以下内容

extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/memcached.so

最后重启nginx和php-fpm，输入php -m命令，如果包含memcache和memcached即为安装成功
