phpmyadmin允许提示错误：

Error during session start; please check your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.

session_start(): open(SESSION_FILE, O_RDWR) failed: Permission denied (13)
这是session存储目录没有执行权限。

方法和我之前提到的phpMyAdmin – Error Cannot start session一样。

打开php.ini，增加：

session.save_path = "/var/lib/php/session"

然后在给予目录：/var/lib/php/session" 执行权限。
