公司想要搭建内部的ITOP平台，今天我尝试了一下，前面都没什么问题，在最后一步Ready to install的步骤卡住了，具体报错：Notice: Undefined index: new_db_name in /var/www/html/itop/web/core/config.class.inc.php on line 1770   
点install后页面出现
Notice: Undefined index: new_db_name in /var/www/html/itop/web/core/config.class.inc.php on line 1770

Fatal error: Uncaught exception 'ConfigException' with message 'Could not find configuration file: file = /var/www/html/itop/web/conf/production/config-itop.php' in /var/www/html/itop/web/core/config.class.inc.php:1157 Stack trace: #0 /var/www/html/itop/web/core/config.class.inc.php(1167): Config->CheckFile('configuration', '/var/www/html/i...') #1 /var/www/html/itop/web/core/config.class.inc.php(1133): Config->Load('/var/www/html/i...') #2 /var/www/html/itop/web/setup/wizardsteps.class.inc.php(2480): Config->__construct('/var/www/html/i...') #3 /var/www/html/itop/web/setup/wizardcontroller.class.inc.php(189): WizStepDone->Display(Object(SetupPage)) #4 /var/www/html/itop/web/setup/wizardcontroller.class.inc.php(131): WizardController->DisplayStep(Object(WizStepDone)) #5 /var/www/html/itop/web/setup/wizardcontroller.class.inc.php(261): WizardController->Next() #6 /var/www/html/itop/web/setup/index.php(61): WizardController->Run() #7 {main} thrown in /var/www/html/itop/web/core/config.class.inc.php on line 1157
请问大家该怎么解决这个问题呢

研究了一天了还是没结果，不要沉啊，到底怎么排除这个问题啊

你可以看一下你的nginx或者http里面的错误日志。
