elasticsearch-无法通过curl访问localhost：9200

Question

I start elasticsearch server and want to access localhost:9200 via curl.

Here is my try:

curl -u elastic:H5VzhJP0txg4Lm9EMSZp localhost:9200

curl -u elastic:H5VzhJP0txg4Lm9EMSZp http://localhost:9200

curl -u elastic:H5VzhJP0txg4Lm9EMSZp http://127.0.0.1:9200

curl -XGET -u elastic:H5VzhJP0txg4Lm9EMSZp http://localhost:9200

curl -XGET -u elastic:H5VzhJP0txg4Lm9EMSZp -H 'Content-Type: application/json' 'http://localhost:9200'

All of them give me the result: curl: (52) Empty reply from server

But, I can access localhost:9200 via browser.

here is my elasticsearch version:

☁  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

I think the reason is the proxy

Here is my config in ~/.zshrc file

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

when I run unproxy in terminal, that means I don't use proxy server.

Then, it works fine.

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

}

Try this.

curl 'username:password@localhost:9200'
curl 'username:password@localhost:9200' -H 'Content-Type: application/json'
