500内部错误＆amp;遵循centos 7安装教程后，权限被拒绝

标签： ckan

按照＆＃34;安装ckan on centos 7＆＃34;教程并做了一些修改（比如使用postgres密码替换传递并用我自己的ip替换域名），我已经启动并运行了postgresql和solr（开始使用tomcat，在端口8080上）。

在development.ini中，我指定了solr_url = http://127.0.0.1:8080/solr/ckan-schema-2.3，我认为应该没问题。

curl http://127.0.0.1:8080/solr/

但是，当我在远程浏览器和localhost中访问CKAN时，我收到内部服务器错误（500）。

在检查了ckan.error.log之后，我发现了以下错误消息，我认为这可能是CKAN（2.4.1）和Solr（1.4.1）之间的连接问题。

2 个答案:

答案 0 :(得分：0)

是的，此错误消息是关键消息：

Problems were found while connecting to the SOLR server

那些CKAN Centos安装说明配置CKAN：

solr_url=http://127.0.0.1:8080/solr/ckan-schema-2.3

当CKAN尝试使用该URL运行SOLR查询时，它失败了。具体来说，它无法连接到127.0.0.1:8080，这通常意味着什么都没有正在侦听，即可能SOLR没有运行。所以这听起来像是一个纯粹的SOLR问题，而不是CKAN问题。

首先检查SOLR是否正在运行并在其主管理界面上进行响应：

curl http://127.0.0.1:8080/solr/

现在检查CKAN所需的SOLR核心是否已配置：

curl -s 'http://127.0.0.1:8080/solr/admin/cores?wt=json&indent=true'

CKAN SOLR核心如下所示：

"ckan":{
  "name":"ckan",
  "instanceDir":"/etc/solr/ckan/",
  "dataDir":"/var/lib/solr/data/",
  "startTime":"2017-10-13T10:32:01.3Z",
  "uptime":1805340,
  "index":{
    "numDocs":50,
    "maxDoc":52,
    "version":1490867603581,
    "segmentCount":9,
    "current":true,
    "hasDeletions":true,
    "directory":"org.apache.lucene.store.MMapDirectory:org.apache.lucene.store.MMapDirectory@/var/lib/solr/data/index lockFactory=org.apache.lucene.store.NativeFSLockFactory@4b3e213f",
    "lastModified":"2017-10-13T10:44:47Z"}}

Centos安装指南为您提供了两个内核，但您只需要后一个内核 - 忽略旧的schema-1.4。检查schema-2.3的名称（核心的前2行）是否设置为：ckan-schema-2.3，根据solr_url中的最后一位（我刚刚ckan上面的例子，这是默认的。）

您可以像这样检查SOLR核心的状态：

curl -s 'http://127.0.0.1:8983/solr/ckan-schema-2.3/admin/ping?wt=json&indent=true'

检查结束时为："status":"OK"

答案 1 :(得分：0)

这可能是创建套接字连接的权限问题。这可能与SELinux有关。查看是否已启用SELinux强制执行：

getenforce

如果是，您需要阅读套接字的权限。
