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;

可以修改为

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

然后在 application 文件夹下 创建一个目录sessions 目录

[vagrant@centos application]# chmod 755 sessions

---

如果目录是放在 类似/home/waka/public_html 目录下并出现类似以下的情况

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

需要给session 文件夹的拥有者为这个文件夹的所属linux系统用户

可以通过 groups 命令查看用户所属的用户组

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