問題：安裝插件慢
root@ip-172-31-2-121:/work/opt/logstash# bin/logstash-plugin install logstash-output-kinesis

WARNING: SSLSocket#session= is not supported

解決：

更換為國內源

[ec2-user@ip-xxx-xxx-xxx-xxx logstash-2.3.0]$ cat Gemfile | grep source  
source "https://rubygems.org"需要將gem source修改為國內的源，  
  
[ec2-user@ip-xxx-xxx-xxx-xxx logstash-2.3.0]$ vim Gemfile  
  
# This is a Logstash generated Gemfile.  
# If you modify this file manually all comments and formatting will be lost.  
  
#source "https://rubygems.org"  
source "https://ruby.taobao.org/"  
......執行
