Hello,

I must install logstash and his plugin on **offline VM**.

**First on online VM I do:**

Install Java and Logstash

```
yum install --downloadonly --downloaddir=/home/logstash/ logstash
yum install --downloadonly --downloaddir=/home/java/ java-1.8.0-openjdk-headless.x86_64
yum install java-1.8.0-openjdk-headless.x86_64
yum install logstash

```

Then the plugins I need:

```
/usr/share/logstash/bin/logstash-plugin install logstash-output-gelf
/usr/share/logstash/bin/logstash-plugin install logstash-output-file
/usr/share/logstash/bin/logstash-plugin install logstash-input-lumberjack

```

After I fix path problem:

```
sudo /usr/share/logstash/bin/system-install /etc/logstash/startup.options systemd

```

Next I export plugin:

`/usr/share/logstash/bin/logstash-plugin prepare-offline-pack logstash-output-gelf logstash-output-file logstash-input-lumberjack`

I copy all with Winscp and SSH.

**Then on Offline VM I do:**

```
[arethusa@logstash opt]$ cd logstash/
[arethusa@logstash logstash]$ ls
logstash-7.8.1.rpm logstash-offline-plugins-7.8.1.zip

[arethusa@logstash logstash]$ sudo yum install logstash-7.8.1.rpm
[arethusa@logstash logstash]$ sudo systemctrl enable logstash

```

Then I try to install logstash offline plugins but I have ruby error:

```
root@logstash arethusa]# /usr/share/logstash/bin/logstash-plugin install /home/arethusa/logstash/logstash-offline-plugins-7.8.1.zip
Validating /home/arethusa/logstash/logstash-offline-plugins-7.8.1.zip

Unable to download data from https://rubygems.org - SocketError: Failed to open TCP connection to rubygems.org:443 (initialize: name or service not known) (https://rubygems.org/latest_specs.4.8.gz)

ERROR: Installation aborted, verification failed for /home/arethusa/logstash/logstash-offline-plugins-7.8.1.zip

```

Anyone know how I can fix it?

Thank you.

Have you tried  
`/usr/share/logstash/bin/logstash-plugin install file:///home/arethusa/logstash/logstash-offline-plugins-7.8.1.zip`  
?
