我将我的 PHP会话文件存储在NFS共享上.问题是,PHP总是创建一个空的会话文件,但不能从中读取/写入,因此对于每个页面重新加载,都会创建一个新文件.

如果我将会话存储路径移动到本地文件夹,会话将正常保存.此外,我正在运行具有相同配置的另一个环境,它运行正常.

在PHP遇到此问题的同一台服务器上,我能够在保存会话的相同目录中创建/写入/读取文件(使用root,非root用户,特别是www-data用户进行测试).

我在ubuntu 12.04 LTS上使用PHP 5.5.12,apache 2.4.9和NFS v3

我的PHP.ini

session.save_handler = files
session.save_path = "2;/mnt/cache/sessions"
session.use_cookies = 1
session.use_only_cookies = 0
session.name = PHPSESSID
session.auto_start = 0
session.cookie_lifetime = 2592000
session.cookie_path = /
session.cookie_domain =
session.cookie_httponly =
session.serialize_handler = PHP
session.gc_PRobabilITy = 1
