## 参考项目
https://github.com/hu3rror/memos-on-fly
## 准备工作
1.注册FLY.IO
用以部署memos
2.注册B2C
https://www.backblaze.com/cloud-storage
用以同步备份memos数据库
新建BUCKET,并获取`<keyId>`和`<applicationKey>`
## 安装flyctl
Install flyctl
以WINDOWS为例
```
pwsh -Command "iwr https://fly.io/install.ps1 -useb | iex"
```
其他系统请参照官方
## 新建APP
初始化
```
flyctl launch
```
按照提示选择会生成一个FLY.TOML文件
## 编辑FLY.TOML
添加以下内容
```
[build]
image = "ghcr.io/hu3rror/memos-litestream:latest"
#如果不需要备份数据库则可以选择官方的docker镜像ghcr.io/usememos/memos:latest
#使用官方镜像可以删掉env的部分
[env]
# Details see: https://litestream.io/guides/backblaze/
LITESTREAM_REPLICA_BUCKET = "B2C桶名称" # change to your litestream bucket name
LITESTREAM_REPLICA_ENDPOINT = "s3.us-east-005.backblazeb2.com" # change to your litestream endpoint url
LITESTREAM_REPLICA_PATH = "memos_prod.db" # keep the default or change to whatever path you want
[[mounts]]
source = "memos_data"
destination = "/var/opt/memos"
[http_service]
internal_port = 5230
force_https = true
auto_stop_machines = false
auto_start_machines = true
min_machines_running = 0
```
## 添加1g存储空间
```
flyctl volumes create memos_data --region hkg --size 1
```
## 添加密钥
将B2存储的密钥添加到fly的密钥存储中,
使用官方镜像可以忽略此步骤
```
flyctl secrets set LITESTREAM_ACCESS_KEY_ID="<keyId>" LITESTREAM_SECRET_ACCESS_KEY="<applicationKey>"
```
## 部署
执行
```
flyctl deploy
```
看到成功的提示可打开域名查看
## 演示地址
https://memosim.fly.dev/
绑定域名演示
https://imad.top
## 下载数据库
`fly.io`部署`artalk`或者`memos`后,使用SFTP下载SQLite 数据库
```
flyctl sftp get ./data/artalk.db #数据库路径
```
