访问PHPMyAdmin报错：Error during sess

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.

是session的读写权限问题，在php.ini可以看到session位置：

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

给予/var/lib/php/session可写权限即可：.

chown -R nginx.nginx /var/lib/php/session

重启 nginx 和 php-fpm

/etc/init.d/php-fpm restart
service nginx restart

刷新PHPMyAdmin页面OK
