我想使用haystack + elasticsearch

所以我安装了elasticsearch

$ brew info elasticsearch

elasticsearch: stable 5.0.1, HEAD
Distributed search & analytics engine

/usr/local/Cellar/elasticsearch/5.0.1 (98 files, 34.8M) *

Config:  /usr/local/etc/elasticsearch/
plugin script: /usr/local/Cellar/elasticsearch/5.0.1/libexec/bin/plugin

To have launchd start elasticsearch now and restart at login:
  brew services start elasticsearch
Or, if you don't want/need a background service you can just run:
  elasticsearch

我开始使用elasticsearch

$ brew services start elasticsearch

我希望反驳我的索引

$ python manage.py rebuild_index

WARNING: This will irreparably remove EVERYTHING from your search index in connection 'default'.
Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.
Are you sure you wish to continue? [y/N] y

但显示错误

Removing all documents from your index because you said so.
DELETE http://127.0.0.1:9200/haystack [status:N/A request:0.002s

[...]

During handling of the above exception, another exception occurred:

产品没有索引...

首先我认为这是连接错误,

$ curl -v -X GET 127.0.0.1:9200

* Rebuilt URL to: 127.0.0.1:9200/
*   Trying 127.0.0.1...
* connect to 127.0.0.1 port 9200 failed: Connection refused
* Failed to connect to 127.0.0.1 port 9200: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 127.0.0.1 port 9200: Connection refused

但我设置了settings.py

# Django Haystack
HAYSTACK_CONNECTIONS = {
    'default': {
    'ENGINE':'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
    'URL': 'http://127.0.0.1:9200/',
    'INDEX_NAME': 'haystack',
    'TIMEOUT': 10
    },
}

我尝试弹性搜索重启,然后重新安装,否则......

但我无法理解为什么......

这是因为你的ES服务器没有启动。

根据您的日志,您需要在discovery.zen.ping.timeout文件中将discovery.zen.ping_timeout更改为/usr/local/etc/elasticsearch/elasticsearch.yml并重新启动ES。
