我正在尝试将RoR应用程序与SQL Server连接。我创建了一个didUpdateValueFor文件，如下所示：
database.yml我已启用TPC / IP，并在SQL Configuration Manager中将端口更改为1434。
当我尝试使用development:
<<: *default
adapter: sqlserver
host: 'pcname\domain'
encoding: 'unicode'
database: 'db_name'
username: 'user'
password: 'pass'
pool: 5
port: 1434
运行迁移时，控制台抛出：
TinyTds :: Error：在配置文件中找不到服务器名称
我以前已经安装了FreeTDS。而且我尝试了使用rake db:migrate和dataserver: 'pcname\domain:1434'而不使用端口
完整跟踪
dataserver: 'pcname\domain'流浪文件

答案 0 :(得分：0)
据我所知，您没有在无用的VM和主机之间转发任何端口，而对于在VM上运行的RoR，它需要执行此操作才能连接到SQL Server的端口。在主机上运行。在流浪者文件中添加以下行：
config.vm.network "forwarded_port", guest: 1434, host: 1434
，您可能还需要取消注释此行，以便可以访问RoR网站：
config.vm.network "forwarded_port", guest: 80, host: 8080
或将上面的端口更改为您在其上运行RoR的任何端口（我相信默认端口为3000，因此3000而非80）
