将外部 zookeper 与 solr cloud 一起使用

Question

我正在尝试实现 solrcloud。我从官方资源 https://cwiki.apache.org/confluence/display/solr/Getting+Started+with+SolrCloud 中弄乱了文档。它适用于嵌入式 zookeper，但建议使用外部 zookeper。我在我的系统上安装了 zookeper，在我的主文件夹上创建了数据字典 zookeper。我创建了名为 1 和 2 的子文件夹，并在文档中提到的每个文件夹中分别创建了带有文本 1 和 2 的 myid 文件。我为 zookeper zoo.cnfg 创建了配置文件

clientPort=2181
initLimit=5
syncLimit=2
server.1=localhost:2879:3879
server.2=localhost:2888:3888

和 zoo2.cnfg

initLimit=5
syncLimit=2
clientPort=2182
server.1=localhost:2878:3878
server.2=localhost:2888:3888

接下来我运行 cd

bin/zkServer.sh start zoo.cfg
bin/zkServer.sh start zoo2.cfg

它已成功启动。接下来我跑

bin/solr start -e cloud -z localhost:2181,localhost:2182 系统问我没有分片等，比如在开始时我为节点 1 8990 和节点 2 8991 选择端口。它给出了错误

Waiting to see Solr listening on port 8991 [/]  Still not seeing Solr listening on 8991 after 30 seconds!

我在哪里失踪？浏览了许多文档，但 apche doc 不适合外部 zookeper 设置。

Answer 1

您的 Zookeeper ensemble 必须有一定数量的节点：1、3、5 等...

如果您想测试 ZK 集群功能，则必须设置至少 3 个 ZK 实例。在这种情况下，不要忘记：

1. 要在 myid 文件中正确设置 ZK 服务器 id，必须在您的 zoo.cfg 引用的目录 dataDir 中创建该 ID。
2. 为每个 ZK 实例分离 dataDir 和 dataLogDir。
