MemCached 安装

1、安装Memcached
2、安装memcache PHP模块
3、测试脚本

一、环境需求 装Memcached需要libevent库的支持,所以请在安装Memcached之前检查有没有安装libevent。测试环境还需要PHP的支持, 本文假设PHP已经安装到/usr/local/php目录下,也就是在编译PHP的时候使用perfix参数指定目录(--prefix= /usr/local/php)

二、下载相关软件
Memcached下载地址 http://www.danga.com/memcached/
memcache PHP模块下载地址 http://pecl.php.net/package/memcache 推荐使用1.5版
libevent 下载地址 http://www.monkey.org/~provos/libevent/

# tar vxzf libevent-1.3e.tar.gz
# cd libevent-1.1a
# ./configure
# make
# make install
建立一个符号连接:#ls -s /usr/local/lib/libevent-1.1.so.1 /usr/lib
2、安装Memcached
# tar memcached-1.2.8.tar.gz
# cd memcached-1.2.8
# ./configure --prefix=/usr/local/memcached
--with-libevent=/usr
# make
# make install

# cd /usr/local/php/modules/memcached/bin
# ./memcached -d -m 50 -p 11211 -u root
参数说明 -m 指定使用多少兆的缓存空间;-p 指定要监听的端口; -u 指定以哪个用户来运行

然后重启web服务器即可。如果安装成功,则通过phpinfo()可以获得该扩展的相关信息:

memcache support enabled
Active persistent connections 0
Version 2.2.5
Revision $Revision: 1.111 $
Directive Local Value Master Value
memcache.allow_failover 1 1
memcache.chunk_size 8192 8192
memcache.default_port 11211 11211
memcache.default_timeout_ms 1000 1000
memcache.hash_function crc32 crc32
memcache.hash_strategy standard standard
memcache.max_failover_attempts 20 20


3、安装memcache PHP模块

# tar vxzf memcache-2.0.4.tgz
# cd memcache-2.0.4
# /usr/local/php/bin/phpize

如果出现:Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF
environment variable is set correctly and then rerun this script.

错误原因是没有安装autoconf,你必须安装以下两个rpm:

rpm -ivh /media/cdrom/Server/imake-1.0.2-3.i386.rpm

rpm -ivh /media/cdrom/Server/autoconf-2.59-12.noarch.rpm

#./configure --with-php-config=/usr/local/php/bin/php-config --with-apxs=/usr/local/apache/bin/apxs --with-gettext --enable-socket --enable-memcache --enable-sysvshm --enable-shmop


# make
# make install

然后修改php.ini

extension_dir = "./"
修改为
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
并添加一行
extension=memcache.so
3、测试脚本
自己写一个PHP程序测试一下吧

Code

运行后输出如下:

Server's version: 1.2.8
Store data in the cache (data will expire in 10 seconds)
Data from the cache: object(stdClass)#3 (2)
{ ["str_attr"]=> string(4) "test" ["int_attr"]=> int(123) }
