Solr 7.4 在我尝试启动时抛出错误

时间：2021-07-23 21:54:42

标签： solr lucene apache-zookeeper solrcloud solr7

我正在将 Solr 从 3 台旧机器迁移到 3 台新机器，但我只能让 Solr 在 3 台新机器中的 1 台上运行。 Solr 在 3 台旧机器上运行良好，但不知道为什么它不能在 2 台新机器上运行。

我在 3 台 RHEL 7 机器上运行 Solr 7.4。

对于 2 台无法启动 Solr 的新机器，我在尝试启动时收到以下错误。

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，当我在所有 3 个新服务器上运行 zookeeper 状态时，它们会相应地报告。我真的很难理解为什么 3 台新服务器中的 1 台正在工作。

此外，这是我在 Solr 运行良好的 1 台主机上获得的输出。

2 个答案:

答案 0 :(得分：1)

因此，在花了数小时尝试解决此问题后，我们发现我们的 2 个新 VM 没有重新创建，使其具有与旧机器相同的规格。它们的 RAM 大约是我们原始机器的一半。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，该值高于新机器的值。将 2 个服务器重建为具有正确规格的新实例后，Solr 开始没有问题。

答案 1 :(得分：0)

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 /etc/sysctl.conf 中添加以下内容并在重新登录后重新启动。

soft nofile 65536
hard nofile 65536
