1、前提条件

（1）、在能上网的服务器上不是logstash，将需要安装的插件安装在该服务器的logstash上。

（2）、利用该服务器上的logstash-plugin程序，生成指定插件离线的zip安装包。

（3）、将离线安装包拷贝到指定服务器上（无法上网的服务器），运行logstash-plugin命令完成安装。

2、生成离线zip安装包

[root@bogon logstash]# ./bin/logstash-plugin prepare-offline-pack logstash-filter-lynis
Offline package created at: /opt/logstash/logstash-offline-plugins-5.6.1.zip

You can install it with this command `bin/logstash-plugin install file:///opt/logstash/logstash-offline-plugins-5.6.1.zip`

3、安装离线包

[root@t0-secure-log2 u01]# ./logstash/bin/logstash-plugin install file:///u01/logstash-filter-lynis-offline.zip 
Installing file: /u01/logstash-filter-lynis-offline.zip
Install successful
