Question

有类似的问题，但我的配置不是我从wkhtmltopdf.org下载了wkhtmltopdf，放在了项目文件夹，我无法弄清楚为什么我仍然被拒绝访问。

尝试指向django运行wkhtmltopdf以生成pdf文件。

使用UNICORN运行NGINX
使用SUPERVISOR
Ubuntu 16

在我的unicorn_supervisor日志中我得到了：

为什么我的访问被拒绝，因为wkhtmltopdf文件所有者是同一个运行的独角兽？

我能够在终端中运行命令，但是python无法运行它。为什么呢？

Answer 1

我通过创建一个shell脚本文件来调用wkhtmltopdf来解决这个问题。

<强> wkhtmltopdf.sh

  CREATE VIEW v_customer AS SELECT *,
    CONCAT(lastName, ', ', firstName ) AS wholeName,
   FROM customers;

谢谢大家的帮助。

Answer 2

只需使用 sudo su 要么 sudo命令这将以超级用户身份运行并绕过所有权限。我是你无法访问超级用户的情况，我不确定。当我试图运行一些不应该运行的东西时，这有时会发生在我身上。虽然我使用的是ubuntu 14.04，所以我不像其他人那样理解这一点。
