1、安装好 ruby 环境
2、下载插件包，例如：
0> wget https://github.com/logstash-plugins/logstash-filter-aggregate 0> unzip master 0> cd logstash-filter-aggregate-master 0> gem build logstash-filter-aggregate.gemspec #会生成 logstash-filter-aggregate-0.1.3.gem 文件 0> /path/to/your/logstash/bin/plugin install /path/to/your/logstash-filter-aggregate-0.1.3.gem Validating ./logstash-filter-aggregate-0.1.3.gem Installing logstash-filter-aggregate Installation successful
3、现在，调用list列出所有的已安装插件列表，会看见刚才安装的aggregate插件：
0> /path/to/your/logstash/bin/plugin list logstash-filter-aggregate
