elasticsearch 不能rebuild_index

Question

我想使用 haystack + elasticsearch

所以我安装elasticsearch

$ brew info elasticsearch

elasticsearch: stable 5.0.1, HEAD
Distributed search & analytics engine
https://www.elastic.co/products/elasticsearch
/usr/local/Cellar/elasticsearch/5.0.1 (98 files, 34.8M) *
  Built from source on 2016-11-29 at 17:52:15
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/elasticsearch.rb
==> Requirements
Required: java >= 1.8 ✔
==> Caveats
Data:    /usr/local/var/elasticsearch/elasticsearch_hanminsoo/
Logs:    /usr/local/var/log/elasticsearch/elasticsearch_hanminsoo.log
Plugins: /usr/local/Cellar/elasticsearch/5.0.1/libexec/plugins/
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

然后我启动 elasticsearch

$ brew services start elasticsearch

我想重建我的索引

$ 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

但是显示错误

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
    },
}

我尝试重新启动 elasticsearch，然后重新安装 pip，否则...

但是我不明白为什么.....

Answer 1

这是因为你的ES服务器没有启动。

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