编译安装PHP使用session_start()时报错&解决办法

A 错误信息：

Warning: session_start(): open(/var/lib/php/session/sess_qavhhacl7lrdbggauasf1qdlo5, O_RDWR) failed: No such file or directory (2) in /www/tool/classes/service/User.php on line 75

Warning: Unknown: open(/var/lib/php/session/sess_qavhhacl7lrdbggauasf1qdlo5, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

B 查看php.ini：

session.save_path = "/var/lib/php/session" // session的存放路径

所以上面的文字是提示没有该目录

C 解决问题：

创建上面的目录

mkdir session

chmod -R 777 session

再次运行程序就OK了

D 查看更多：

(1)

pwd
/var/lib/php/session
? session ls
sess_qavhhacl7lrdbggauasf1qdlo5

用firebug查看cookie:

PHPSESSID qavhhacl7lrdbggauasf1qdlo5 // php.ini session.name = PHPSESSID
