Openshift環境變量不存在

Question

我在安裝中添加了一個MySQL盒式磁帶，通過CLI界面運行php時可以看到環境變量。

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

但是，通過Web界面調用同一變量時，未設置該變量。 我已經通過rhc app restart重新啟動了Apache和整個應用程序

有人告訴您不要對IP地址進行硬編碼，因為它會更改。 例如https://developers.openshift.com/en/managing-environment-variables.html

但是，當您在網站上運行腳本時，IP地址丟失了。

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

你明白了 IP地址丟失。

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

代替

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

這可能是因為您沒有使用Git將文件推送到服務器上 。 您可能像我一樣（討厭嗎？），而我的簡單網站更喜歡sftp。

所需步驟-如果您不熟悉git
在您的OpenShift網站上，找到“應用程序”選項卡，“源代碼”

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

假設您在本地安裝了git。 這將從服務器上獲取OpenShift git存儲庫的副本，並將其放在本地計算機上。

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

克隆到'php'...

將一些文件復制到它在本地計算機上創建的php子文件夾中

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

這將重新啟動您的應用程序和mysql。

現在您的環境變量將正常工作。 是的，sftp可能更快。
