安装memcached服务器和PHP中添加memcache拓展模块

Memcached是一个高性能的分布式内存对象缓存系统,用于动态web应用以减轻数据库的负载。它通过在内存中缓存数据和对象来减少读取数据库的次数,从而提拱动态 数据驱动网站的速度。

memcached是其于libevent做事件触发的,首先装libevent.

wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
[root@14LN src]# tar -xzvf libevent-2.0.21-stable.tar.gz

[root@14LN libevent-2.0.21-stable]# ./configure --prefix=/usr/local/libevent
[root@14LN libevent-2.0.21-stable]# make && make install
[root@14LN libevent-2.0.21-stable]# ls -al /app/server/libevent/lib/ |grep libevent

接下来安装Memcached:

[root@14LN src]# wget http://pkgs.fedoraproject.org/lookaside/pkgs/memcached/memcached-1.4.15.tar.gz/36ea966f5a29655be1746bf4949f7f69/memcached-1.4.15.tar.gz
[root@14LN src]# tar -xzvf memcached-1.4.15.tar.gz
[root@14LN src]# cd memcached-1.4.15
[root@14LN memcached-1.4.15]# ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent
[root@14LN memcached-1.4.15]# make && make install
安装php扩展模块memcache
[root@14LN src]# wget http://pecl.php.net/get/memcache-2.2.6.tgz
[root@14LN src]# cd memcache-2.2.6
[root@14LN memcache-2.2.6]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212
[root@14LN memcache-2.2.6]# ./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir
[root@14LN memcache-2.2.6]# make && make install 安装成功会有类似下面的提示:
Build complete.
Don't forget to run 'make test'. Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/ [root@14LN memcache-2.2.6]# egrep 'memcache|extension_dir' /etc/php.ini
[memcache]
extension_dir="/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/"
extension=memcache.so
; extension_dir = "./"
; extension_dir = "ext"
; Be sure to appropriately set the extension_dir directive.
;sqlite3.extension_dir =
启动memcache
[root@14LN memcache-2.2.6]# /usr/local/memcached/bin/memcached -d -u root -m 63 -p 11211 -c 10240
[root@14LN memcache-2.2.6]# service php-fpm restart
