在许多服务器上，甚至个人站点都提供了ImageMagick的下载。推荐访问ImageMagick的官方主页获取最新版本的源码包。以ImageMagick-5.5.6.tar.gz为例，统筹管理源码整站Linux安装步骤如下：
首先解压源码包：tar zxvf ImageMagick-5.5.6.tar.gz
进入解压后的目录：cd ImageMagick-5.5.6
配置安装：./configure
编译安装：make all
以超级用户身份安装：su 或 sudo（在Debian/Ubuntu系统上直接执行sudo aptitude install imagemagick即可安装）
安装后，记得将函数库目录添加到/etc/profile文件中的算命程序源码aspLD_LIBRARY_PATH环境变量，同时确保在/etc/ld.so.conf中包含该路径，并运行ldconfig以确保应用能正确找到ImageMagick库，避免出现运行问题。
