无法在 rails 应用程序中使用 sunspot / solr 重新索引 - 错误：solr 配置中的严重错误

Question

好的，我有一个简单的 Rails 应用程序，现在我正在尝试实现 sunspot 的搜索功能。但是，在我使用 rails g sunspot_rails:install 生成配置文件之后，在我启动服务器并且它在我的 rails app-dir 中创建了 solr-dir 并且我运行 bundle exec rake sunspot:solr:reindex I得到以下跟踪：

cakism@saraswati:~/railscode/calendar$ bundle exec rake sunspot:solr:reindex --trace
** Invoke sunspot:solr:reindex (first_time)
** Invoke sunspot:reindex (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sunspot:reindex

rake aborted!
RSolr::Error::Http - 500 Internal Server Error
Error: Severe errors in solr configuration.

Check your log files for more detailed information on what may be wrong.

If you want solr to continue after configuration errors, change:

 <abortOnConfigurationError>false</abortOnConfigurationError>

in null

我对此特别好奇：

If you want solr to continue after configuration errors, change:

 <abortOnConfigurationError>false</abortOnConfigurationError>

in null

为什么会显示为空？与我有相同问题的其他帖子已指定 solr/conf/solrconfig.xml，而且，当我将其更改为 false 时，没有其他任何反应。

如果我从我的模型中删除可搜索块，我不会收到任何错误（但我想那是因为它不会尝试做任何事情）

我通过 XML 验证器运行了配置文件，它说它的起始标签名称错误，位于 2

我在这里开始感到绝望，所以非常感谢任何帮助！

Answer 1

我遇到了一个非常相似的问题并解决了它

• 停止所有正在运行的 solr 进程
• 删除 solr 文件夹
• 关闭/重新启动计算机
• gem 卸载所有相关的 gems
• 捆绑安装
• 启动 solr
• 重新索引 solr

Answer 2

它偶尔发生在我身上。在我的情况下，这是 solr（不是太阳黑子）问题

试着去

http://localhost:8982/solr/admin

or http://localhost:8983/solr/admin

or http://[your.domain]:8983/solr/admin

（取决于你使用的环境）

看看你在 solr web server 下有什么错误

我看到了 java 错误消息并通过删除索引目录并重新启动 solr 来修复它

它开始按预期运行

希望对你有帮助

Answer 3

或者您可以重新安装 gem。这对我有用。

Answer 4

这是一种简单的方法（不需要弄乱宝石或重新启动计算机）：

rake sunspot:solr:stop

如果您修改了架构，请将site_root/solr/conf/schema.xml 的内容复制到剪贴板

接下来，删除site_root/solr处的整个solr文件夹

现在运行：

rake sunspot:solr:start

此命令将创建并重新填充已删除的 solr 文件夹。

如果您在上面复制了 schema.xml，请再次打开 schema.xml，选择所有内容，然后复制剪贴板中的内容。保存文件。

现在运行：

bundle exec rake sunspot:solr:reindex

Answer 5

更具体地说，我找到了问题的原因，希望这对任何想知道发生了什么的人有所帮助

首先，我删除了 solr/data 文件夹。馊主意。这导致了 cakism 所描述的错误。

重启、删除 solr 文件夹等都无济于事。仅仅因为有一个 Solr 服务器实例正在运行，即使使用 sunspot:solr:stop 也不会停止。您必须通过以下方式杀死该实例：

rake sunspot:solr:stop # stop server
ps -A | grep solr      # you'll see the [PID] of the solr server
kill [PID]             # replace with the [PID] from above to completely kill the solr instance

之后，您可以继续删除 solr 文件夹并再次启动服务器

Answer 6

我遇到了同样的问题，最后我得到了 config/database.yml 的数据库名称错误，而且我检查了 sunspot.yml，这个文件也有错误的配置，比如 ip 地址。我修改了这两个文件，然后它就开始工作了。

Answer 7

对我来说，turn off/restart the computer 有很大的依赖关系（无法重新启动），并且从上面不起作用（我没有尝试重新启动）。所以，我的工作解决方案是

1. 进入应用根目录。
2. 使用ps aux | grep solr找到solr process ID
3. stop solr process using kill -9 4313 # 对我来说 4313 是 solr process id

4. 在暂存时启动 solr rake sunspot:solr:start RAILS_ENV=staging

5. 使用rake sunspot:solr:reindex RAILS_ENV=staging重新索引solr

就是这样。

注意：根据需要更换环境
