logstash插件升级

环境：

os: centos 7.7

ip: 10.8.6.246

logstash版本：6.7.0 (/usr/share/logstash/bin/logstash -V)

查看当前插件版本：

/usr/share/logstash/bin/logstash-plugin list --verbose

会看到如下

...
logstash-filter-urldecode (3.0.6)
logstash-filter-useragent (3.2.3)
logstash-filter-xml (4.0.7)
logstash-input-beats (5.1.8)
logstash-input-dead_letter_queue (1.1.4)
logstash-input-elasticsearch (4.3.0)
logstash-input-exec (3.3.2)
logstash-input-file (4.1.9)
...

备份当前版本（可选）

 /usr/share/logstash/bin/logstash-plugin prepare-offline-pack logstash-input-file

会打包当前版本的插件

(base) [root@bdp-c-204 service]# /usr/share/logstash/bin/logstash-plugin prepare-offline-pack logstash-input-file
Offline package created at: /usr/share/logstash/logstash-offline-plugins-6.7.0.zip

You can install it with this command `bin/logstash-plugin install file:///usr/share/logstash/logstash-offline-plugins-6.7.0.zip`

后续如果回滚，可以从本地安装

升级指定插件

我们要升级**logstash-input-file (4.1.9)**到最新版本

/usr/share/logstash/bin/logstash-plugin update logstash-input-file

成功后可以看到提示Updated logstash-input-file 4.1.9 to 4.2.4
