# nvwa
|
||||
|
||||
#### 介绍
|
||||
A daemon process for kernel online update
|
||||
|
||||
#### 软件架构
|
||||
软件架构说明
|
||||
一个用于自动化openEuler热升级过程的工具
|
||||
|
||||
#### 构建方式
|
||||
|
||||
```
|
||||
cd src
|
||||
go get nvwa
|
||||
go build
|
||||
```
|
||||
|
||||
#### 关于配置
|
||||
|
||||
配置文件放置在config目录下，运行时二进制会去三个地方寻找配置文件，按照先后为：
|
||||
|
||||
1. 运行目录
|
||||
2. 运行目录的config子目录
|
||||
3. /etc/nvwa
|
||||
|
||||
配置文件包括:
|
||||
|
||||
1. nvwa-restore.yaml
|
||||
|
||||
需要进行现场恢复的进程和服务，两者区别在于，对于每一个服务，nvwa会去修改systemd的配置，通过systemd恢复运行状态
|
||||
|
||||
2. nvwa-server.yaml
|
||||
|
||||
热升级使用中需要用到的目录，日志，二进制目录配置等等
|
||||
|
||||
|
||||
#### 安装教程
|
||||
#### 支持的命令
|
||||
|
||||
1. xxxx
|
||||
2. xxxx
|
||||
3. xxxx
|
||||
+ nvwa check -- 运行环境检查
|
||||
|
||||
#### 使用说明
|
||||
+ nvwa update <version> -- 热升级到相应的内核版本(相关文件需放置在/boot下)
|
||||
|
||||
1. xxxx
|
||||
2. xxxx
|
||||
3. xxxx
|
||||
nvwa将会去/boot目录下寻找需要的kernel和rootfs，kernel的命名格式需为vmlinuz-<version>, rootfs命名格式需为initramfs-<version>.img
|
||||
|
||||
#### 参与贡献
|
||||
+ nvwa restore <process> -- 恢复某个之前freeze的进程
|
||||
|
||||
1. Fork 本仓库
|
||||
2. 新建 Feat_xxx 分支
|
||||
3. 提交代码
|
||||
4. 新建 Pull Request
|
||||
+ nvwa help
|
||||
|
||||
显示client相关的帮助信息
|
||||
|
||||
#### 特技
|
||||
+ nvwa --help
|
||||
|
||||
1. 使用 Readme\_XXX.md 来支持不同的语言，例如 Readme\_en.md, Readme\_zh.md
|
||||
2. Gitee 官方博客 [blog.gitee.com](https://blog.gitee.com)
|
||||
3. 你可以 [https://gitee.com/explore](https://gitee.com/explore) 这个地址来了解 Gitee 上的优秀开源项目
|
||||
4. [GVP](https://gitee.com/gvp) 全称是 Gitee 最有价值开源项目，是综合评定出的优秀开源项目
|
||||
5. Gitee 官方提供的使用手册 [https://gitee.com/help](https://gitee.com/help)
|
||||
6. Gitee 封面人物是一档用来展示 Gitee 会员风采的栏目 [https://gitee.com/gitee-stars/](https://gitee.com/gitee-stars/)
|
||||
显示server相关的帮助信息
|
||||
|
||||
#### 开发计划
|
||||
|
||||
+ 将/boot目录下kernel和rootfs的命名格式放入配置项
|
||||
+ 支持日志重定向至文件
|
||||
+ 配置文件改变后，服务自动重新加载
|
||||
+ server必须以root权限运行
|
||||
+ server/client帮助文本的问题
|
||||
+ 优化使用体验
|
||||
+ 配置文件存在模糊的地方
|
||||
+ nvwa的启动时机存在一定问题(criu对lsm之类存在依赖)
|
||||
+ 网络dump/restore变成可选(否则会造成开机网络失效)
