安装php拓展 imagick，上来就编译 ImageMagick，出现各种问题：
1 convert: no decode delegate for this image format `JPG‘ @ error/constitute.c/ReadImage/561. 2 convert: no decode delegate for this image format `PNG‘ @ error/constitute.c/ReadImage/561. 3 ERROR: `/tmp/pear/temp/imagick/configure --with-imagick‘ failed
试了很多方案，并没有解决：

后来发现采用简单的 yum 安装 ImageMagick，再编译 imagick 拓展就能用了
1 yum install -y ImageMagick 2 yum install -y ImageMagick-devel
