centos 5.5 安装 memcached 手记

pecl install memcached
出现错误：
ERROR: `/var/tmp/memcached/configure' failed

memcached 安装参考http://www.cnblogs.com/zgx/archive/2011/08/10/2134097.html

pecl install memcache

出现错误

只能编译安装：
wget http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz

var memcached-1.4.5.tar.gz

cd memcached-1.4.5

./configure

又出错：configure: error: memcache support requires ZLIB. Use --with-zlib-dir=<DIR> to specify prefix where ZLIB include and library are located

说缺少ZLIB

那就安装zlib

yum install zlib-devel -y

安装 libevent 

yum install  libevent libevent-devel -y

安装完毕之后，顺利./configure

./configure

make

make install

vi /etc/php.d/memcache.ini
