在Cloud Foundry上部署开源CMS 'my little forum'(需要PHP和MySQL)

Question

我的小论坛是一个简单的基于PHP和MySQL的互联网论坛以经典的线程视图（树状结构）显示消息。它是根据GNU通用公共许可证授权的开源软件。主要这个网络论坛声称简单。此外，它应该很容易使用PHP和MySQL。

我尝试在基于CloudFoundry的主机上部署mylittleforum。

安装

解压缩脚本包。将完整的文件夹"论坛"上传到您的服务器。

根据您的服务器配置子目录templates_c（CHMOD 770、775或777）和文件config/db_settings.php（CHMOD 666）可能需要更改它们可由脚本写入。运行安装脚本的方式在您的web浏览器中访问您的域.tld/forum/install/，然后按照说明。

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/

CF推送输出

PHP构建包选项（.bp-config/options.json）

$ pwd
/Users/RomeoOw/Downloads/mylittleforum-2.3.5
$ cat .bp-config/options.json 
{
    "WEBDIR": ""
}

我ssh到容器中（在删除应用程序并再次推送之后，这是奇怪的时间戳，我想是因为S3文件缓存）：

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）。错误路径CCD_ 2给出404，而好路径/install/给出500。在日志中，我看到的信息最多的是状态代码为500。CF应用程序输出似乎健康mylittleforum started 1/1 1G 1G mylittleforum.domain

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

cf set-env mylittleforum BP_DEBUG true

做了一次重新发布，也没有发现关于我在Safari中的请求的有用信息，结果是500。在我提出请求之前，有很多调试日志。参见此处的cf logs --recent输出

当我访问其他URL /index.php/install/时，有额外的HTTP标头（Set-Cookie、Pragma、Expires和Cache-Control）

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

Answer 1

在构建包选项中设置WEBDIR：

构建包似乎试图为构建包配置的WEBDIR变量中定义的文件夹提供服务，默认为htdocs。mylittleforum希望从项目的根目录提供文件，所以请尝试将buildpack选项值更改为空字符串。

从环境中获取配置：

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