PHP 升级至 5.3.3 后会话停止工作

Question

yum在我更新 PHP 到 5.3.3之后，我无法登录任何 PHP 应用程序（phpmyadmin、mediaWiki）

我看过其他帖子，但似乎没有针对该问题的总体修复，有很多单独的修复，但我都没有成功。

我正在运行 CentOS 6.5，这些是我的会话变量，如所列php -i

session.auto_start => Off => Off
session.bug_compat_42 => Off => Off
session.bug_compat_warn => Off => Off
session.cache_expire => 180 => 180
session.cache_limiter => nocache => nocache
session.cookie_domain => no value => no value
session.cookie_httponly => Off => Off
session.cookie_lifetime => 0 => 0
session.cookie_path => / => /
session.cookie_secure => Off => Off
session.entropy_file => no value => no value
session.entropy_length => 0 => 0
session.gc_divisor => 1000 => 1000
session.gc_maxlifetime => 1440 => 1440
session.gc_probability => 1 => 1
session.hash_bits_per_character => 5 => 5
session.hash_function => 0 => 0
session.name => PHPSESSID => PHPSESSID
session.referer_check => no value => no value
session.save_handler => files => files
session.save_path => /var/lib/php/session => /var/lib/php/session
session.serialize_handler => php => php
session.use_cookies => On => On
session.use_only_cookies => On => On
session.use_trans_sid => 0 => 0

这些是会议文件夹：

$ ls -la  /var/lib/php
drwxrwxr-x   2 root apache 4096 Jan 14 11:28 session

我已经清空了该文件夹，因为我读到过旧的会话可能会导致问题。

我没有主动改变这些或其他php.ini设置、会话在更新后就停止工作。
