我想运行Wordpress＆amp;在minikube上的mySQL并不能让它工作。
命令看起来简单明了。在kubectl命令中没有看到任何错误。
mbp/~:$kubectl run mysql --image=mysql:5.7 --env MYSQL_ROOT_PASSWORD=password
deployment "mysql" created
mbp/~:$kubectl get pods

mysql 10.0.0.92 <none> 3306/TCP 1m
mbp/~:$kubectl run wordpress --image=wordpress --env WORDPRESS_DB_HOST=mysql --env WORDPRESS_DB_PASSWORD=password
然而，wordpress容器一直在崩溃，说它无法连接到mySQL。
我可以登录mySQL pod并通过列出数据库来检查它是否正常工作。
以下是wordpress pod的错误消息。
MySQL Connection Error: (2002) php_network_getaddresses: getaddrinfo failed:
Name or service not known
Warning: mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed:
Name or service not known in - on line 22
Warning: mysqli::mysqli(): (HY000/2002): php_network_getaddresses:
getaddrinfo failed: Name or service not known in - on line 22
wordpress配置有正确的mysql条目（我通过exec进入wordpress容器检查了这个）
define(‘DB_HOST’, ‘mysql’);
我可以在另一个kubernetes集群（在IBM Bluemix中托管）上运行这些命令，我想知道如何解决这个问题。
我尝试了三种不同的mySQL图像（5.5,5.6和5.7），结果相同。
总的来说，我的minikube似乎运作良好。有没有办法解决这里可能发生的事情？
在我删除了pod时更新了mysql和wordpress pod的新问题。
mbp/~:$kubectl run mysql --image=mysql:5.7 --env MYSQL_ROOT_PASSWORD=password

答案 0 :(得分：1)
由于这些命令在其他Kubernetes集群中工作（除了我的minikube），我怀疑我的minikube设置有问题。我不记得在minikube安装过程中发现任何错误。
我删除了本地Kubernetest群集（使用minikube delete）并删除了“ .minikube ”目录下的所有内容（在用户的主目录中）
启动minikube，这创建了一个新的minikube VM，并运行相同的命令，并且工作正常。
我想当事情没有按预期发挥作用时，这可能是我们在迷你世界中需要做的事情。这比尝试解决问题容易得多！
