Codeigniter Session: Configured save path is not a directory

Codeigniter 3.x

Message: Session: Configured save path '' is not a directory, doesn't exist or cannot be created.

配置文件config.php 中

$config['sess_save_path'] = NULL;

可以修改為

$config['sess_save_path'] = APPPATH.'sessions';

然后在 application 文件夾下 創建一個目錄sessions 目錄

[vagrant@centos application]# chmod 755 sessions

---

如果目錄是放在 類似/home/waka/public_html 目錄下並出現類似以下的情況

Configured save path `/home/waka/public_html/application/sessions` is not writable by the PHP process

需要給session 文件夾的擁有者為這個文件夾的所屬linux系統用戶

可以通過 groups 命令查看用戶所屬的用戶組

[vagrant@centos application]# groups waka
waka: waka
[vagrant@centos application]# chown waka:waka sessions
