PHP会话不存储/保存 - php-fpm / nginx / phpmyadmin / centos6

Question

我最近搬到了一个新的服务器，现在突然间我的PHP会话变量没有存储。

我已经安装了nginx和php-fpm，两者似乎都可以工作，因为我可以执行其他php操作。

我知道我的代码很好，因为它在我部署它的过去5台服务器上运行得很好。

由于某种原因，我无法存储会话变量。

phpMyAdmin返回此信息

“phpMyAdmin - 错误无法启动会话而没有错误，请检查PHP和/或Web服务器日志文件中给出的错误并正确配置PHP安装。还要确保在浏览器中启用了cookie。”

Here is my php error log which shows some errors in regards to the session storage.

我做了一些研究，似乎可能是一个可能的权限错误？ 关于这个问题，没有太多文件或任何关于此问题的文件。 这似乎是一个非常独特的问题，特别是考虑到我已经完成了许多Web服务器配置，这是我第一次遇到这个问题。

我希望也许这里有更多专业知识的人可以解释一下。

Answer 1

您需要刷新浏览器缓存，删除服务器/主机的cookie，然后重试加载phpMyAdmin。

如果您想全力以赴，请清除服务器上的会话文件夹。

一个可能的原因是浏览器和网络服务器之间的会话数据不匹配导致它无法提取所需的会话信息并将此错误对话转储到您的膝盖上。

另一个问题可能是文件和文件夹权限; 您可以尝试更改文件夹权限：

sudo chmod 777 /var/lib/php/session/

这将在PHP会话文件夹上设置完全读/写权限。

注意：php / session /文件夹可能位于某些服务器上的不同位置。 检查你的php.ini是否有你的会话路径。

Answer 2

虽然这是有效的，但不应该做，因为它是不安全的。 在我的情况下，正确的方法是将PHP会话文件夹的组更改为运行Web服务器的用户。 在我的情况下我使用nginx所以我将使用sudo chown root:nginx /var/lib/php/session/
