用的是centos系统

1、安装memcached

yum -y install memcached

安装完成后，

memcached -h

应该会出现memcached 参数说明

2、memcached配置文件

vi /etc/sysconfig/memcached PORT="11210"USER="memcached"MAXCONN="1024"CACHESIZE="64"OPTIONS=""

3、安装libmemached

wget tar -zxvf libmemcached-1.0.16.tar.gzcd libmemcached-1.0.16./configure -prefix=/usr/local/libmemcached -with-memcached make && make install

这步出现了两个错误

第一个gcc错误，因为本地用的centos最小安装

yum -y install gcc+ gcc-c++

第二个错误是libmemcached版本错误，下载了 libmemcached-1.0.18.tar.gz 和 libmemcached-1.0.17.tar.gz

都会出错,最后安装1.6版本的才可以

4、 php-devel

yum install php-devel

5、安装PHP Memcached扩展

wget tar -zxvf memcached-2.2.0.tgzcd  memcached-2.2.0/usr/local/php/bin/phpize ./configure -enable-memcached --disable-memcached-sasl -with-zlib-dir -with-libmemcached-dir=/usr/local/libmemcached -prefix=/usr/local/phpmemcached make && make install

中间可能会出现一个错误：memcache support requires ZLIB

yum install zlib-devel

6、增加扩展extension配置文件

vi /etc/php.d/memcached.ini extension=memcached.so #增加这行

检测是否安装

php -m|grep memcached

会出现"memcached"

7、启动memcached

/usr/bin/memcached -m 64m -p 11211 -d -u root -P /var/run/memcached.pid -c 256

最后可以用phpinfo();

应该会出现在 memcached
