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 https://launchpad.net/libmemcached/1.0/1.0.16/+download/libmemcached-1.0.16.tar.gz
tar -zxvf libmemcached-1.0.16.tar.gz
cd 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 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
./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
