具有 SSL 和基本身份验证的 SolrCloud
SolrCloud with SSL and Basic Authentication
是否可以使用 SSL 和基本身份验证配置 SolrCloud？
我已经使用 SSL 在 SolrCloud 中配置了 3 个 Solr 节点：https://cwiki.apache.org/confluence/display/solr/Enabling+SSL
并且我在这之后添加了身份验证和授权：
https://cwiki.apache.org/confluence/display/solr/Basic+Authentication+Plugin, https://cwiki.apache.org/confluence/display/solr/Rule-Based+Authorization+Plugin
当仅启用 SSL 时它可以工作。
仅启用身份验证+授权时有效
当两者都启用时，我在启动期间得到以下堆栈跟踪：

2016-06-01 17:19:47.288 WARN (qtp1185255965-22) [ ] o.a.s.s.PKIAuthenticationPlugin Failed to decrypt header, trying after refreshing the key
看起来所有安全插件都工作正常，但是当它们全部启用时基本身份验证不使用超级用户，它们之间的节点无法通信。知道哪里出了问题吗？
原来 security.json 中的“blockUnknown”属性 是万恶之源。从头开始完成所有步骤后，即使是简单的身份验证也无法使用此 属性 集。所以我决定尽可能减少配置，一旦我从 security.json.
中删除了 blockUnknown，我就开始工作了
我不确定这个 属性 到底有什么问题，但在调试会话后我发现了可能的错误。内部 solr 节点通信在获取集群中节点的 public 密钥时失败，可能是因为这个 属性 与身份验证有关。由于某种原因，节点未进行身份验证。
无论如何...现在我通过 SSL 进行身份验证 + 授权，我可以在 SSL 级别阻止未知主机。 Brawo Ja!
编辑：我今天发现了一件在这个问题的背景下很重要的事情。尽管集合访问是安全的，但所有其他 url 都不是！我从 solrCloud wiki 页面以某种方式错过了这个：所有请求 w/o 凭据将被拒绝并出现 401 错误。如果您希望允许未经身份验证的请求通过，请将 'blockUnknown' 设置为 false（或将其完全删除）。但是，如果特定资源受规则保护，它们无论如何都会被拒绝并返回 401 错误 .. 所以总结这个 属性 是相当必要的。我为此创建了 jira 问题。
此问题现已在 Solr 6.2.1 上修复！
升级后，我现在可以将 SSL 和基本身份验证一起正常工作，并将 blockUnknown 设置为 true。
干杯！
我有一个相关问题，这个 post 似乎最接近我的问题。
我无法使用设置的凭据 solr/SolrRocks 登录 Solr 管理控制台。
我在 windows 环境中使用 SOlr 6.6 和 Zookeeper 3.4.10。
我的问题是在使用命令上传 security.json 文件后：
server/scripts/cloud-scripts/zkcli -zkhost localhost:9983 -cmd putfile
/security.json security.json
并在 SOLR 上启用这些参数：
set SOLR_AUTH_TYPE=basic
set SOLR_AUTHENTICATION_OPTS="-Dbasicauth=solr:SolrRocks"
服务器启动正常，但我无法登录到 SOLR 管理控制台。
我收到错误：HTTP 错误 401，凭据错误"
我已在此站点的另一个 post 中记录了关于此问题的详细步骤：
Solr Cloud with Basic Authentication fails - Unauthorized 401 Error from Solr Admin
我尝试的另一件事是使用 "put" 命令而不是 "putfile" 命令。我在 SOlr 服务器上得到一个 classcastexception。不确定如何解决 Solr 管理员访问问题！
使用"put"命令时出错：
java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Map

是否可以使用 SSL 和基本身份验证配置 SolrCloud？
我已经使用 SSL 在 SolrCloud 中配置了 3 个 Solr 节点：https://cwiki.apache.org/confluence/display/solr/Enabling+SSL
并且我在这之后添加了身份验证和授权： https://cwiki.apache.org/confluence/display/solr/Basic+Authentication+Plugin, https://cwiki.apache.org/confluence/display/solr/Rule-Based+Authorization+Plugin
当仅启用 SSL 时它可以工作。
仅启用身份验证+授权时有效
当两者都启用时，我在启动期间得到以下堆栈跟踪：

看起来所有安全插件都工作正常，但是当它们全部启用时基本身份验证不使用超级用户，它们之间的节点无法通信。知道哪里出了问题吗？
原来 security.json 中的“blockUnknown”属性 是万恶之源。从头开始完成所有步骤后，即使是简单的身份验证也无法使用此 属性 集。所以我决定尽可能减少配置，一旦我从 security.json.
中删除了 blockUnknown，我就开始工作了我不确定这个 属性 到底有什么问题，但在调试会话后我发现了可能的错误。内部 solr 节点通信在获取集群中节点的 public 密钥时失败，可能是因为这个 属性 与身份验证有关。由于某种原因，节点未进行身份验证。
无论如何...现在我通过 SSL 进行身份验证 + 授权，我可以在 SSL 级别阻止未知主机。 Brawo Ja!
编辑：我今天发现了一件在这个问题的背景下很重要的事情。尽管集合访问是安全的，但所有其他 url 都不是！我从 solrCloud wiki 页面以某种方式错过了这个：所有请求 w/o 凭据将被拒绝并出现 401 错误。如果您希望允许未经身份验证的请求通过，请将 'blockUnknown' 设置为 false（或将其完全删除）。但是，如果特定资源受规则保护，它们无论如何都会被拒绝并返回 401 错误 .. 所以总结这个 属性 是相当必要的。我为此创建了 jira 问题。
此问题现已在 Solr 6.2.1 上修复！
升级后，我现在可以将 SSL 和基本身份验证一起正常工作，并将 blockUnknown 设置为 true。
干杯！
我有一个相关问题，这个 post 似乎最接近我的问题。 我无法使用设置的凭据 solr/SolrRocks 登录 Solr 管理控制台。
我在 windows 环境中使用 SOlr 6.6 和 Zookeeper 3.4.10。 我的问题是在使用命令上传 security.json 文件后：
server/scripts/cloud-scripts/zkcli -zkhost localhost:9983 -cmd putfile
/security.json security.json
并在 SOLR 上启用这些参数：
set SOLR_AUTH_TYPE=basic
set SOLR_AUTHENTICATION_OPTS="-Dbasicauth=solr:SolrRocks"
服务器启动正常，但我无法登录到 SOLR 管理控制台。 我收到错误：HTTP 错误 401，凭据错误"
我已在此站点的另一个 post 中记录了关于此问题的详细步骤：
Solr Cloud with Basic Authentication fails - Unauthorized 401 Error from Solr Admin
我尝试的另一件事是使用 "put" 命令而不是 "putfile" 命令。我在 SOlr 服务器上得到一个 classcastexception。不确定如何解决 Solr 管理员访问问题！
使用"put"命令时出错：
