我正在尝试设置一个 Vagrant 环境，该环境涉及一些带有 Ansible 的 Ubuntu 机器，但在编写 Ansible Playbook 来自动执行该过程时遇到了问题。主要是，我遵循此答案中的说明 - https://stackoverflow.com/a/26598887

这是我在运行剧本时遇到的错误片段；

据我所知，第一个“安装 mysql”步骤似乎没有运行。为了验证这一点，我设法通过直接从命令行运行 ansible 模块来重现问题；

vagrant@mgmt:~$ ansible web -m apt -a "name=mysql-server update_cache=yes cache_valid_time=3600 state=latest" --sudo

知道如何安装 mysql 并使用 Ansible 设置数据库吗？

最佳答案

我在尝试在新的 ubuntu/trusty64 机器上安装 mysql 时发生了同样的错误。疯狂的是，结果证明是由于 VM 实例的内存少于 512MB。确保您的 Vagrantfile 为您的 VM 分配了足够的内存。

config.vm.provider "virtualbox" do |vb|
  vb.memory = "512"
end
