安装jdbc插件

生产环境不能联网；虽然logstash是开箱即用，即解压后就能使用，但是对于logstash-input-jdbc插件来说，一般是在线安装的（./logstash-plugin install logstash-input-jdbc）

就算你是在github上https://github.com/logstash-plugins/logstash-input-jdbc/下载源码，修改Gemfile，也要联网来安装。所以对于不能联网的机子来说必须使用

./logstash-plugin install file:///path/to/logstash-input-jdbc.zip 这种方式来安装。但是官方并没有提供像x-pack一样的离线安装包。那么我们就需要在一台能联网的机子上先在线安装好logstash-input-jdbc插件，然后使用logstash-plugin命令里面的打包离线安装包命令将插件打包为离线的，再传送到生产环境就可以了

一个能联网的机子上解压logstash后，在线安装jdbc插件：

# ./logstash-plugin install logstash-input-jdbc
