Question

我已经在安装中添加了一个MySQL盒，并且可以在通过CLI界面运行php时看到环境变量。

php -r'echo $ _SERVER [“OPENSHIFT_MYSQL_DB_HOST”];' // 127.2.234.2

但是，当通过Web界面调用同一变量时，未设置变量。我通过rhc app restart重新启动了apache和整个应用程序

Answer 1

您被告知不要硬编码IP地址，因为它会改变。例如https://developers.openshift.com/en/managing-environment-variables.html

但是当您在网站上运行脚本时，IP地址丢失了。

<?php
print(getenv('PHPRC'));
print('<p>');
print(getenv('OPENSHIFT_MYSQL_DB_HOST'));
?>

你明白了。 IP地址丢失。

/var/lib/openshift/xxf1b5b94382ec898b00xxxx/php/configuration/etc/php.ini

而不是

/var/lib/openshift/xxf1b5b94382ec898b00xxxx/php/configuration/etc/php.ini
127.5.nnn.nnn

这可能是因为您没有使用Git将文件推送到您的服务器。你可能喜欢我（一个luddite？）和我的简单网站的首选sftp。

需要的步骤 - 如果您不熟悉git
查看您的OpenShift网站，“应用程序”选项卡，源代码

ssh://xxf1b5b94382ec898b00xxxx@xxxx-xxxxx.rhcloud.com/~/git/php.git/

这假设你在本地安装了git。这需要从服务器上取下OpenShift git存储库的副本并将其放在本地计算机上。

git clone ssh://xxf1b5b94382ec898b00xxxx@pappname.rhcloud.com/~/git/php.git/

克隆到'php'......

将一些文件复制到它在本地计算机上创建的php子文件夹

$ git add .
$ git commit -m "A change to my application"]
$ git push

这将重启你的应用程序和mysql。

现在您的环境变量将正常工作。是的，sftp可能更快。

Openshift环境变量不存在
