elasticsearch - elasticsearch-无法通过curl访问localhost:9200

Question

我启动elasticsearch服务器，并希望通过curl访问localhost:9200。

这是我的尝试:
curl -u elastic:H5VzhJP0txg4Lm9EMSZp localhost:9200curl -u elastic:H5VzhJP0txg4Lm9EMSZp http://localhost:9200curl -u elastic:H5VzhJP0txg4Lm9EMSZp http://127.0.0.1:9200curl -XGET -u elastic:H5VzhJP0txg4Lm9EMSZp http://localhost:9200curl -XGET -u elastic:H5VzhJP0txg4Lm9EMSZp -H 'Content-Type: application/json' 'http://localhost:9200'
他们全都给我结果:curl: (52) Empty reply from server
但是，我可以通过浏览器访问localhost:9200。

这是我的elasticsearch版本:

☁  kibana-research [master] ⚡  elasticsearch --version
Java HotSpot(TM) 64-Bit Server VM warning: Cannot open file logs/gc.log due to No such file or directory

Version: 6.2.4, Build: ccec39f/2018-04-12T20:37:28.497551Z, JVM: 1.8.0_171

Answer 1

我认为原因是proxy
这是我在~/.zshrc文件中的配置

 98 # proxy list
 99 alias proxy='export all_proxy=socks5://127.0.0.1:1086'
100 alias unproxy='unset all_proxy'

当我在终端中运行 unproxy时，这意味着我不使用代理服务器。

然后，它工作正常。

☁  kibana-research [master] ⚡  curl -u elastic:H5VzhJP0txg4Lm9EMSZp localhost:9200
