我是 ruby 和 chef 的新手。我建立了一个 Chef 服务器并成功引导了一个节点。我想在没有 Mysql 和数据库说明书的情况下通过我的说明书访问节点上的 Mysql。我使用了 ruby/mysql API。当在单个 ruby 文件中编程时,它运行良好。代码如下。
require "rubygems"
require "mysql"
begin
con = Mysql.new("localhost", "root", "123")
res = con.query("create database abc")
rescue Mysql::Error => e
puts e.errno
puts e.error
ensure
con.close if con
end
但是,当我将此代码添加到我的 Recipe 中的 ruby_block 和 chef-client 时,我在节点上遇到了错误。

我不知道什么时候出了问题。有人可以帮忙吗?
最佳答案
Chef 在其自己的 ruby 实例中运行(假设您已使用 omnibus 安装)。您需要使用 chef_gem 将 mysql gem 安装到 Chef ruby 中。资源。然后你应该能够加载 mysql ruby
