在 Stretch 中升级 nginx 时出错

在上一次 Debian Stretch 路由安全更新中，我遇到了一个问题。当尝试安装安全升级并随后升级时nginx，我收到以下错误。

我尝试apt-get upgrade再次运行，或者apt-get install使用任何涉及的软件包，但似乎没有任何效果。

该怎么办？

最终，分析问题，并查看安装后脚本，确定了问题所在。安装/升级任何这些nginx组件时，每一个软件包，请尝试重新启动nginx并检查操作是否成功。

因此，在我们的更新操作中，我们必须monit在执行维护安全更新/升级周期之前开始停止，以免它nginx在apt-get upgrade.

修复最终是按顺序进行的：

  • 停止monit；
  • (p)kill -9对进程进行 a nginx（奇怪的是，停止似乎不再有效）
  • 做一个service start nginx
  • 最后再做apt-get upgrade一次。
  • 最后，升级成功结束service monit start。

这次没有monit碍事，upgrade果然有效。

归根结底，我们的教训是修改我们的标准升级程序，并更改我们的 Ansible 剧本以monit在安全更新过程之前停止或理想情况下暂停。
