Elasticsearch

1 docker 安装 Elasticsearch

  https://www.elastic.co/guide/en/elasticsearch/reference/5.0/docker.html#docker-cli-run-prod-mode

docker pull docker.elastic.co/elasticsearch/elasticsearch:5.0.2

docker run -itd --name es -p 9200:9200 -e "http.host=0.0.0.0" -e "transport.host=127.0.0.1" docker.elastic.co/elasticsearch/elasticsearch:5.0.2

2 在终端里访问 REST API 时报错

在终端里访问 REST API 的时候

1	curl -XGET 'localhost:9200/_cat/health?v&pretty'

会报错

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

{ "error": { "root_cause": [ { "type": "security_exception", "reason": "missing authentication token for REST request [/_cat/health?v&pretty]", "header": { "WWW-Authenticate": "Basic realm=\"security\" charset=\"UTF-8\"" } } ], "type": "security_exception", "reason": "missing authentication token for REST request [/_cat/health?v&pretty]", "header": { "WWW-Authenticate": "Basic realm=\"security\" charset=\"UTF-8\"" } }, "status": 401 }

解决办法是添加上账号密码就好了

1	curl --user elastic:changeme -XGET 'localhost:9200/_cat/health?v&pretty'

这个账号密码实际上是 X-Pack 这个插件附带的认证功能。X-Pack 是一个 Elastic Stack 的扩展，将安全，警报，监视，报告和图形功能包含在一个易于安装的软件包中。

3 查找elasticsearch.yml文件

find / | grep config/elasticsearch.yml
