linux下为PHP扩展安装memcache模块

sh# tar -zxvf libevent-1.4.6-stable.tar.gz
sh# cd libevent-1.4.6-stable
sh# ./configure -prefix=/usr/local/libevent
sh# make
sh# make install
sh# cd ../
sh# tar -zxvf memcached-1.2.6.tar.gz
sh# cd memcached-1.2.6
sh# ./configure --prefix=/usr/local/memcache --with-libevent=/usr/local/libevent
sh# make
sh# make install

安装php的memcache扩展

1 可以使用php自带的pecl安装程序
   # /usr/local/servers/php5/bin/pecl install memcache

2 sh# cd ../
sh# tar -zxvf memcache-3.0.1.tgz
sh# cd memcache-3.0.1
sh# /usr/local/bin/phpize (先要执行下这个,路径由: sh# which phpize 获取)
sh# ./configure -enable-memcache -with-php-config=/usr/local/bin/php-config -with-zlib-dir (路径由: sh# which php-config 获取)
sh# make
sh# make install (提示: Installing shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-20060613/ 则成功)

安装完后会有类似这样的提示：
Installing shared extensions: /usr/local/servers/php5/lib/php/extensions/no-debug-non-zts-20060922/

把这个记住，然后修改php.ini，把

extension_dir = "./"
修改为
extension_dir = "/usr/local/servers/php5/lib/php/extensions/"

并添加一行
extension="no-debug-non-zts-20060922/memcache.so"
