我的小论坛是一个简单的基于PHP和MySQL的互联网论坛   在经典线程视图（树结构）中显示消息。它   是根据GNU通用公共许可证授权的开源软件。主要的   这个网络论坛的主张很简单。此外，它应该很容易   使用PHP和。在标准服务器配置上安装和运行   的MySQL。

我尝试在基于Cloud Foundry的托管上部署mylittleforum。

  

安装

     

解压缩脚本包。   将完整的文件夹“论坛”上传给你的。

     

根据您的服务器配置，写入权限   子目录templates_c（CHMOD 770,775或777）和文件   可能需要按顺序更改config / db_settings.php（CHMOD 666）   他们可以通过脚本写入。运行安装脚本   在您的网络浏览器中访问yourdomain.tld / forum / install /并按照   说明。

我做了什么：

wget -nd https://github.com/ilosuna/mylittleforum/archive/v2.3.5.tar.gz
tar xvfz v2.3.5.tar.gz
cd mylittleforum-2.3.5/
cf cs mariadb large mylittleforum-db
cf push mylittleforum -b https://github.com/cloudfoundry/php-buildpack.git
cf bs mylittleforum mylittleforum-db
cf env mylittleforum
vi config/db_settings.php 
<?php
// Database host, mostly 'localhost':
$db_settings['host'] = '10.0.20.18';

// Database name:
$db_settings['database'] = 'CF_39CC64E1_578D_IIF3_BF1F_BC06LDIDK74009';

// Database user name:
$db_settings['user'] = '84mwzL9fonrlptzmGn';

// Database password:
$db_settings['password'] = 'xzG1s0dff89lYtunp5Mn';

// Database tables (normally not necessary to edit): 
$db_settings['settings_table'] =       'mlf2_settings';
$db_settings['forum_table'] =          'mlf2_entries';
$db_settings['category_table'] =       'mlf2_categories';
$db_settings['userdata_table'] =       'mlf2_userdata';
$db_settings['smilies_table'] =        'mlf2_smilies';
$db_settings['pages_table'] =          'mlf2_pages';
$db_settings['banlists_table'] =       'mlf2_banlists';
$db_settings['useronline_table'] =     'mlf2_useronline';
$db_settings['login_control_table'] =  'mlf2_logincontrol';
$db_settings['entry_cache_table'] =    'mlf2_entries_cache';
$db_settings['userdata_cache_table'] = 'mlf2_userdata_cache';
?>
chmod 777 config/db_settings.php
cf push mylittleforum -b https://github.com/cloudfoundry/php-buildpack.git

然后尝试启动安装程序，但收到404.更新发现安装程序位于http://mylittleforum.domain/install/ 

curl -I http://mylittleforum.domain/forum/install/

我试过了：

$ curl -I http://mylittleforum.domain/install/
HTTP/1.1 500 Internal Server Error
Content-Type: text/html
Date: Sun, 31 Jul 2016 14:27:06 GMT
Server: Apache
X-Vcap-Request-Id: ab6db4f1-78ff-483e-7b74-09211fd0b6b9

这是我的应用程序日志（我尝试了错误和良好的路径）。错误的路径/forum/install/给出404并且好的路径/install/给出500.在日志中我看到的信息不是状态代码为500的事实.CF应用输出似乎是健康的mylittleforum started 1/1 1G 1G mylittleforum.domain

我看了app/.bp/logs/bp.log cf ssh。没什么用的。启用BP调试后，日志目录丢失了。

cf set-env mylittleforum BP_DEBUG true

是否进行了冲压，并且在Safari中找不到有关我的请求的有用信息，导致500.在我的请求之前有很多调试日志。请参阅cf logs --recent输出here

当我访问其他网址/index.php/install/时，会有其他HTTP标头（Set-Cookie，Pragma，Expires和Cache-Control）

curl -I http://mylittleforum.domain/index.php/install/

答案 0 :(得分：1)

在buildpack选项中设置WEBDIR：

似乎buildpack尝试提供buildpack配置的<?php session_start(); if($_SESSION["id"]!=$_GET["id"] or $$_GET["referrer"]!="allowedsite.com"){ echo "not valid"; die(); } ?> 变量中定义的文件夹，默认为WEBDIR。 mylittleforum希望从项目的根目录提供文件，因此请将changing the buildpack option值设为空字符串。

从环境中获取配置：

除此之外，我建议您通过使用htdocs（see manual）函数获取相应的环境变量来设置config/db_settings.php。
