处理为#因为用户 www没有HOME 会跑到root导致没权限，可指定 export HOME=/tmp/ && 解决
$shell = "export HOME=/tmp/ && /usr/bin/libreoffice --headless --convert-to html --print-to-file --printer-name nasty_lowres_printer --outdir {$_SERVER['DOCUMENT_ROOT']}/out_file/ {$full_result_path} > /dev/null 2>/dev/null &";php如果做了函数安全过滤，需要放行shell_exec, tp 控制器upload
