Question

我试图用Sequel连接到db2数据库。我在使用带有Ruby的CentOS映像的OpenShift平台上。我安装了ibm_db：gem 'ibm_db', '~> 3.0', '>= 3.0.5'，我试图通过Sequel连接如下：

require 'sequel'
require 'ibm_db'

require_relative 'database_logger'

def create_database_connection(logger)

  credentials = {
    adapter: "ibmdb",
    database: "myexampledb",
    host: "myexamplehost.com",
    port: "80",
    username: ENV['DB_USERNAME'],
    password: ENV['DB_PASSWORD'],
    encoding: 'utf8'
  }

  if ENV['PACT_BROKER_DATABASE_PORT'] =~ /^\d+$/
    credentials[:port] = ENV['PACT_BROKER_DATABASE_PORT'].to_i
  end

  connection = Sequel.connect(credentials.merge(logger: DatabaseLogger.new(logger), encoding: 'utf8'))
  connection.extension(:connection_validator)
  connection.pool.connection_validation_timeout = -1
  connection
end

但我收到以下消息：

我不确定是什么错误。

ls -a /opt/app-root/src/.gem/ruby/extensions/x86_64-linux/2.3.0/ibm_db-3.0.5/

向我展示了ibm_db.so。

ldd显示：

libdb2.so.1存在：/opt/app-root/src/.gem/ruby/gems/ibm_db-3.0.5/lib/clidriver/lib/libdb2.so.1 但是将其添加到LD_LIBRARY_PATH中，如下所示：

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/app-root/src/.gem/ruby/gems/ibm_db-3.0.5/lib/clidriver/lib/

无济于事。也许有人有想法？

如果我尝试将libdb2.so.1复制到/usr/lib64找到了libdb2.so.1，但我收到以下错误：! Unable to load application: Sequel::DatabaseConnectionError: UncaughtThrowError: uncaught throw :"Connection failed: [IBM][CLI Driver] SQL10007N Message \"0\" could not be retrieved. Reason code: \"3\". SQLCODE=-1042"
