【问题讨论】：

  • tmp 文件夹是否有必要的权限
  • 关闭错误 4ever 我应该怎么做
  • 您正在尝试取消链接 /tmp/ 文件夹中的文件，但您没有该文件的权限。 chmod -R 777

标签： codeigniter hosting web-hosting codeigniter-3


【解决方案1】：

通常在共享主机上，php 安装的tmp 文件夹不可访问，因此 CodeIgniter 无法记录会话。
您可以将会话保存路径更改为您的相对站点路径以解决此问题。

转到config.php 并更改

$config['sess_save_path'] = NULL;

到

$config['sess_save_path'] = BASEPATH . 'application/cache/';

确保缓存文件夹的权限为777。
