在 Ubuntu 22.04.1 上（AMD 3970x 处理器，64GB 内存（memtest86 通过），根文件系统有几 TB 可用空间，没有 SMART 错误），我按照这里的标准说明安装了社区版 mongodb 。在 systemd 中启动 mongod 时，它失败了，并显示以下journalctl -xe消息：

同一次启动尝试的更多具体错误消息出现在 /var/log/mongodb/mongod.log-

这似乎表明 tzdata 包存在问题，因此我通过几种方式进行了检查-

  • dpkg --verify tzdata # 没有错误或输出
  • 检查apt日志，zgrep -i tzdata /var/log/apt/*.gz昨天（2025 年 3 月 31 日）有更新
  • 检查利雅得 tzdata 文件，find /usr/share/zoneinfo|grep "Riyadh"|xargs -n 1 zdump -v没有错误消息，尽管其中有几条记录包含“NULL”，但不清楚这是否表示存在问题。

因此，我卸载了该版本（apt remove mongodb-org-server mongodb-org-shell mongodb-org-tools mongodb-org-mongos mongodb-org-database mongodb-org-database-tools-extra mongodb-mongosh mongodb-database-tools）

然后，我从社区版存档页面下载了 .deb 文件，安装了之前的版本，先后安装了 8.0.5、8.0.4、8.0.3、8.0.1 和 8.0.0。我一个个地安装、启动，检查是否失败——全部失败——/var/log/mongodb/mongod.log 中都出现了相同的错误：“FailedToParse: 无法解析时区标识符为“Asia/Riyadh87”的时区文件”。

这可能是“我的问题”，但 tzdata 中格式不受支持的时区文件不太可能进入 Ubuntu 的仓库，而不影响任何其他服务，也不会立即得到修补。不过，我之前在 Ubuntu 22.04 上遇到过 tzdata 问题，并能够通过 解决apt reinstall。

我更喜欢在裸机上运行服务，因此我付出了很多努力，如果有人能提供一些建议，我将不胜感激。现在，我会在 Docker 上启动 mongodb，然后咬紧牙关。

更新 - 安装 mongodb-server-org 会添加一个默认的 /etc/mongod.conf，其中包含 -

processManagement:
  timeZoneInfo: /usr/local/share/tzdb

我尝试过使用这些行和不使用这些行开始，没有区别，mongod 仍然扫描 Ubuntu 的内置 tzdb 并断言失败。

因此我下载了 tzdb并将其解压到 /usr/local/share/mytzdb，将 mongod.conf 指向该位置，然后启动 mongod - 没有结果，以同样的方式失败。

也许有一个环境变量被覆盖了？目前我在 Docker 下运行，没有问题。

哦，今天早上 Ubuntu 更新刷新了 tzdb，哈哈。不过 mongod 没修复。
