CA 重启期间 FreeIPA 安装在失败

我正在尝试设置一个简单的 vagrant box 来测试 FreeIPA。我使用的是 CentOS 7 镜像，并在 box 上安装了最少的额外东西，并使用非常简单的 FreeIPA 定义开始。我尝试使用简单的 shell 命令来执行此操作，也尝试使用ansible-freeipa。在这两种情况下，我都看到相同的错误，尽管发生的频率似乎不同。在简单的 shell 命令中，它只有大约 50% 的时间会失败，但使用 Ansible 时，它​​似乎是 100%。

失败导致我出现如下错误。

查看 /var/log/messages，我发现错误发生在系统时间 23:25 到 23:27 之间。根据错误信息，这是在 CA 重新启动时发生的。它第一次启动时似乎可以正常启动。

但是，当我查看 PKI 日志时，此时间范围内没有任何内容。以下是 /var/log/pki/pki-ca-spawn.20200302231442.log 中的最后几行：

/var/log/pki/pki-tomcat/ca/debug 相同：

/var/log/pki/pki-tomcat/ca/system 有几个错误，但 23:25 之后没有错误：

我不知道是什么原因造成的。有什么想法吗？vagrant 文件和 hosts 文件都位于以下 GitHub 存储库中：https://github.com/davidov541/HadoopOnVagrant/tree/AnsibleRetrofit/FreeIPA

答案1

最后的ansible错误：

'CA did not start in %ss' % timeout)\r\nRuntimeError: CA did not start in 300.0s\r\n"

这让我想起了邮件列表中出现的一些问题，它是通过将脚本上的 Starting_timeout 变量设置为更高的值来解决的。

解决方案如下：

https://www.freeipa.org/page/HowTo/FreeIPA_on_banana_pi

也许可以尝试一些东西，我不能保证它能帮你解决问题，但是......

答案2

我最终将 vagrant box 的大小增加到 2 GB 以解决我看到的另一个问题，从昨天开始重新创建 box 10-20 次后，我再也没有看到这个问题。基于此，我认为问题是由于 tomcat 没有足够的内存来按需要启动，导致了我们看到的行为。
