Rails and Azure: TinyTds::Error: Adaptive Server connection failed
Rails and Azure: TinyTds::Error: Adaptive Server connection failed
我正在尝试在 Azure 上使用 SQL 配置我的 Rails 项目。我正在使用 Mac OS X 10.11.
这是我的一部分 config/database.yml:
staging:
adapter: sqlserver
mode: dblib
host: db-staging.database.windows.net
port: 1433
database: db-staging
username: myuser@db-staging
password: mypass
timeout: 5000
azure: true
当我 运行 tsql 似乎一切正常时:
$ tsql -H db-staging.database.windows.net -U myuser -P 'mypass' -v -p 1433 -D db-staging
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Setting db-staging as default database in login packet
Changed database context to 'db-staging'.
Changed language setting to us_english.
1>
但是当我 运行 rake db:migrate 我收到这个错误 TinyTds::Error: Adaptive Server connection failed.
这是完整的轨迹：
$ rake db:migrate RAILS_ENV=staging --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:
* development - set it to false
* test - set it to false (unless you use a tool that preloads your test environment)
* production - set it to true
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
rake aborted!

[更新]
我试过完全按照这里的方式做：
https://github.com/Azure/azure-sql-database-samples/tree/master/Ruby%20on%20Rails/Sample%20Mac
按照此 post 我找到了要在我的 config/database.yml 中设置的正确配置。
https://azure.microsoft.com/en-us/documentation/articles/sql-database-develop-ruby-simple-mac-osx/
staging:
adapter: sqlserver
username: 'username@database'
password: 'password'
host: 'db-staging.database.windows.net'
port: 1433
database: 'db-staging'
azure: true
并在我的 Gemfile:
中添加此宝石
gem 'tiny_tds'
gem 'activerecord-sqlserver-adapter'
现在，当我访问我的项目文件夹和 运行 rails s 时，我可以连接到我的数据库并且一切正常。但是，如果我 运行 我的项目使用 Puma 和 Nginx，我收到这个错误：
TinyTds::Error (Adaptive Server connection failed):
[/更新]
需要自己安装FreeTDS，如果apt-get无法传递编译参数：
wget http://ibiblio.org/pub/Linux/ALPHA/freetds/stable/freetds-stable.tgz
$ tar -zxvf freetds-stable.tgz
$ cd freetds-0.91/
$ ./configure --with-tdsver=8.0 --with-openssl=/usr/bin
$ make
$ sudo make install
现在我可以访问我的数据库了：
$ tsql -C # OK!
$ TDSVER=8.0 tsql -H mydb.database.windows.net -p 1433 -U myuser@mydb -P mypassword -D mydb
当我 运行 并使用 Puma、Nginx 和 Capistrano 访问时一切正常。

并在我的 Gemfile:
gem 'tiny_tds'
gem 'activerecord-sqlserver-adapter'
现在，当我访问我的项目文件夹和 运行 rails s 时，我可以连接到我的数据库并且一切正常。但是，如果我 运行 我的项目使用 Puma 和 Nginx，我收到这个错误：

[/更新]
需要自己安装FreeTDS，如果apt-get无法传递编译参数：
wget http://ibiblio.org/pub/Linux/ALPHA/freetds/stable/freetds-stable.tgz
$ tar -zxvf freetds-stable.tgz
$ cd freetds-0.91/
$ ./configure --with-tdsver=8.0 --with-openssl=/usr/bin
$ make
$ sudo make install
现在我可以访问我的数据库了：
$ tsql -C # OK!
$ TDSVER=8.0 tsql -H mydb.database.windows.net -p 1433 -U myuser@mydb -P mypassword -D mydb
当我 运行 并使用 Puma、Nginx 和 Capistrano 访问时一切正常。
