无法与任何数据库主机 Build 连接

我一直在尝试在Centos 6.8和Ubuntu 14.04上安装Phabricator . 在两次尝试中，使用phab配置MySQL时，我收到以下错误：

EXCEPTION: (PhabricatorClusterStrandedException) Unable to establish a connection to any database host (while trying "phabricator_config"). All masters and replicas are completely unreachable. at [<phabricator>/src/infrastructure/storage/lisk/PhabricatorLiskDAO.php:140]

我一直在关注此安装指南：https://secure.phabricator.com/book/phabricator/article/configuration_guide/

我也试图在网上关注其他人，但没有成功 . 尝试的命令是

./bin/storage升级

我也试过了

./bin/storage upgrade --user --password

和其他命令，如在./bin/config上设置主机或用户，但似乎都会导致相同的错误 .

我不知道该做什么，我一直在玩我能找到的每个配置 .
