elasticsearch version "number" : "2.3.5"

centos version 3.10.0-327.22.2.el7.x86\_64

Install elasticsearch by yum with repo

[elasticsearch-2.x]  
name=Elasticsearch repository for 2.x packages  
baseurl=https://packages.elastic.co/elasticsearch/2.x/centos  
gpgcheck=1  
gpgkey=https://packages.elastic.co/GPG-KEY-elasticsearch  
enabled=1  
with /etc/elasticsearch.yml , I just modify one line  
**network.host: xx.xx.xx.xx**  
Elasticsearch start fail, view log do not show anything

But when let it commented as default, elasticsearch start ok.

With the default it listen on 127.0.0.1:9200 127.0.0.1:9300

I can not connect it from outside

I have try to do the same on centos 6 , everything ok

So Centos 7 is the problem ? How can i fix it

Check indentation.

Or paste here your raw Elasticsearch.yml file (formatted as code).

As you say "Check indentation" save me a lot of time.
