泊塢窗：失敗與MySQL數據庫連接

Question

我試圖Mysql容器Piwik連接「PHP應用程序」杉杉我運行mysql的容器是這樣的：

docker run --name piwik -e MYSQL_ROOT_PASSWORD=123456 -d mysql 

然後我試圖運行以及與此關聯的piwik應用命令：

docker run -d -e PIWIK_MYSQL_USER=root -e PIWIK_MYSQL_PASSWORD=123456 -e PIWIK_MYSQL_DBNAME=piwik -e PIWIK_MYSQL_PREFIX=piwik_ --link piwik:piwikmysql --name vpiwik marvambass/piwik 

然而，當我檢查日誌我看到這個錯誤：

ERROR 2005 (HY000): Unknown MySQL server host 'mysql' (0) 
>> no DB installed, MYSQL User or Password specified - seems like the first start

mysql服務器（主機）名稱是不同的數據庫名稱。要解決您的問題，請更改爲，

--link piwik:mysql
