最近，我将一个网站从 Ubuntu 迁移到 Centos，并开始注意到用户在执行交易后会看到一个空白的响应页面。Apache 日志中有这些消息。

不确定哪里出了问题。如果能提出任何建议来解决这个问题，我将不胜感激。
答案1
这些文件不属于 apache，因此，您需要将 fonts/*.afm 文件的 chmod 设置为 +w 到 other，以便为 apache ( chmod 666 fonts/*.afm) 授予写入权限。或者，将所有权授予 apache ( chown apache fonts/*.afm)。
可能还需要为所有这些文件设置适当的文件所有权。因为似乎无法找到这些用户# 1001 的用户名。
