我正在将 Solr 从 3 台旧机器迁移到 3 台新机器，我只能让 Solr 在 3 台新机器中的一台上运行。Solr 在 3 台旧机器上运行良好，但无法弄清楚为什么它不能在 2 台新机器上运行。

我在 3 台 RHEL 7 机器上运行 Solr 7.4。

对于 Solr 无法启动的 2 台新机器，我在尝试启动它时收到以下错误。

有人对如何解决这个问题有任何想法吗？我已经更新了所有配置设置以使用 Zookeeper 中的新 IP，并且当我在所有 3 台新服务器上运行 zookeeper 状态时，它们会相应地报告。我真的很难理解为什么 3 台新服务器中有 1 台正在运行。

此外，这是我在 Solr 运行良好的 1 台主机上获得的输出。

因此，在花费数小时尝试解决此问题后，我们发现我们的 2 台新 VM 没有重新创建以具有与旧机器相同的规格。他们的内存大约是我们原来机器的一半。因此，每当我们在它们上启动 Solr 时，它们都不会启动，因为作为 Solr 启动过程的一部分，我们为 RAM 设置了一个自定义大小，该值比新机器的值更高。在将 2 个服务器重建为具有正确规格的新实例后，Solr 开始时没有出现任何问题。

这只是一个警告，如果您将使用大数据，您应该解决它。所以你需要在你的操作系统中添加打开文件的限制。如果您使用 Linux，请在重新登录后添加以下内容/etc/sysctl.conf并重新启动它。

soft nofile 65536
hard nofile 65536

更多信息：设置打开文件限制 (Linux/Unix)
