安裝jdbc插件

生產環境不能聯網；雖然logstash是開箱即用，即解壓后就能使用，但是對于logstash-input-jdbc插件來說，一般是在線安裝的（./logstash-plugin install logstash-input-jdbc）

就算你是在github上https://github.com/logstash-plugins/logstash-input-jdbc/下載源碼，修改Gemfile，也要聯網來安裝。所以對于不能聯網的機子來說必須使用

./logstash-plugin install file:///path/to/logstash-input-jdbc.zip?這種方式來安裝。但是官方并沒有提供像x-pack一樣的離線安裝包。那么我們就需要在一臺能聯網的機子上先在線安裝好logstash-input-jdbc插件，然后使用logstash-plugin命令里面的打包離線安裝包命令將插件打包為離線的，再傳送到生產環境就可以了

一個能聯網的機子上解壓logstash后，在線安裝jdbc插件：

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