CentOS7下Imagick读取PDF报Postscript delegate失败求助

环境 #

• CentOS 7
• Apache
• PHP 7.4

测试代码 #

$ofile = 'test.pdf';
$imagick = new Imagick();
$imagick->readImage($ofile);

执行报错信息 #

Fatal error: Uncaught ImagickException: Postscript delegate failed `[ghostscript library 9.25] -sstdout=%stderr -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r72x72' '-sOutputFile=/tmp/magick-16528HfVzp_FNGdCX%d' '-f/tmp/magick-16528LrkMb-C0CmIS' '-f/tmp/magick-165281qaTU7bnOBON'': ./base/gsicc_manage.c:1244: gsicc_open_search(): Could not find default_gray.icc | ./base/gsicc_manage.c:2261: gsicc_init_iccmanager(): cannot find default icc profile ./base/gsicc_manage.c:1244: gsicc_open_search(): Could not find default_rgb.icc | ./base/gsicc_manage.c:2025: gsicc_set_device_profile(): cannot find device profile **** Unable to open the initial device, quitting. @ error/ghostscript-private.h/InvokeGhostscriptDelegate/171

已尝试的无效方案 #

• 重装Imagick扩展
• 手动添加环境变量：

putenv('PATH=' . getenv('PATH') . ':/usr/share/ghostscript/lib:/usr/share/ghostscript/iccprofiles:/usr/share/ghostscript/Resource/Init/');

解决方案 #

已解决！问题根源是PHP Jail限制了GhostScript访问ICC配置文件的路径权限，解除对应路径的访问限制后，Imagick即可正常读取PDF文件。
