nexus 的数据库备份是比较重要的,可以方便我们在故障的是时候进行应用恢复。
以下使用benthos 组件进行nexus 数据库备份事件的应用通知处理
环境准备
使用docker-compose 运行
- docker-compose.yaml 文件
version: "3"
services:
nexus:
image: sonatype/nexus3
ports:
- "8081:8081"
volumes:
- ./nexus-data:/nexus-data
- ./backup/:/backup/
benthos:
image: jeffail/benthos
volumes:
- "./webhook.yaml:/benthos.yaml"
ports:
- "4195:4195"
smtp2http:
image: dalongrong/smtp2http
command: --listen=:25 --webhook=http://benthos:4195/ --strict=false
- 启动
docker-compose up -d
- 说明
如果出现权限的问题,可以直接设置777 权限,简单(但是不是很合理)chmod 777 backup nexus-data
配置webhook 功能
使用全局webhook
- 配置全局audit webhook
注意地址使用docker-compose 内置的服务发现功能,实际上就是benthos 服务的信息
- 配置db exporter 任务
如下
运行任务&&查看效果
- 启动任务
直接点击run运行配置的db exporter 任务 - 效果

说明
我们可以用这个功能,使用备份好的数据,以及通知,进行nexus 备份机器的启动还原,方便在故障出现的时候,快速恢复系统,但是有一个要就,就是仓库数据
也同时做了备份,或者使用了共享存储
