php连接memcached缓存服务器的客户端有两个，一个是memcache是比较底层的开发库，memcached是比较新的开发库，php安装这两个扩展中的任意一个后就可以在编写php代码时使用的memcached缓存数据，达到缓存php执行的结果 [b]1、安装memcache [/b]tar -zxvf memcache-2.2.7.tgz cd memcache-2.2.7 /usr/local/php/bin/phpize ./configure –with-php-config=/usr/local/php/bin/php-config  make && make install 安装成功后会有如下类似提示 Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/ 在 /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/ 该目录下会生成memcache.so 编辑 php.ini添加如下 extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/memcache.so 重启php-fpm 查看是否已经加载memcache模块 [img]http://img.1sucai.cn/uploads/article/2018010710/20180107100132_0_92369.png[/img] [b]2、安装memcached [/b]由于memcached是基于libmemcached开发的因此要先安装libmemcached 安装libmemcached要安装gcc44 gcc44-c++ yum  install  gcc* export CC="gcc44" export CXX="g++44" tar -zxvf libmemcached-1.0.18.tar.gz    cd libmemcached-1.0.18 ./configure –prefix=/usr/local/libmemcached make && make install tar -zxvf memcached-2.2.0.tgz cd memcached-2.2.0 /usr/local/php/bin ./configure –with-php-config=/usr/local/php/bin/php-config     –with-libmemcached-dir=/usr/local/libmemcached/ make && make install 安装完成后也有类似memcache的提示 在 /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525 路径下会出现memcached.so 编辑 php.ini添加如下 extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/memcached 重启php-fpm查看php是否支持了memcached [img]http://img.1sucai.cn/uploads/article/2018010710/20180107100133_1_72854.png[/img]
