1，lotus-seal-worker

• GPU服务器，POST时空证明
  lotus daemon
lotus-storage-miner

• 远程存储矿工Remote storage miner worker，复制证明
  lotus-seal-worker

2，存储过程

AddPiece 添加扇区
PreCommit 预提交
Commit 提交
Unseal 解封

3，远程矿工

3.1，lotus-storage-miner节点运行环境

• 运行lotus daemon 和lotus-storage-miner run

# ps aux | grep lotus | grep -v grep
lotus daemon
lotus-storage-miner run

• 区块高度同步完成

# lotus sync wait
Worker 0: Target: [bafy2bzaceb6uqvftvtnid4ornqxibjcapv4z5z65z2e7xu76w5u42fcmk662u]	State: complete	Height: 10533
Done!

• 修改config.toml
• 默认路径~/.lotusstorage/config.toml
• 自定义的路径$LOTUS_STORAGE_PATH/config.toml

# vim  $LOTUS_STORAGE_PATH/config.toml
#[API]
[API]
#  ListenAddress = "/ip4/127.0.0.1/tcp/2345/http"
  ListenAddress = "/ip4/192.168.0.201/tcp/2345/http"
#  Timeout = "30s"
  Timeout = "30s"

• 重启lotus-storage-miner，使配置文件生效。

• cat /storage/lotuswork/lotusstorage/api 配置文件127.0.0.1为变为IP地址

• 生产token

• lotus-storage-miner auth create-token --perm admin

# lotus-storage-miner auth create-token --perm admin
eyJhbG...

• 查看api

# cat $LOTUS_STORAGE_PATH/api
/ip4/192.168.0.201/tcp/2345/http

3.2，lotus-seal-worker运行节点，远程节点

• 可能有更简单的方便，我的环境是这样的。
• 下载lotus源代码编译安装

# which lotus
/usr/local/bin/lotus
# which lotus-storage-miner
/usr/local/bin/lotus-storage-miner
# which lotus-seal-worker
/usr/local/bin/lotus-seal-worker

• make lotus-seal-worker检查是否有安装

# make lotus-seal-worker
make: *** 没有规则可制作目标“lotus-seal-worker”。 停止。

• /var/tmp/filecoin-proof-parameters 有所需要的复制证明参数

• 设置环境变量
  STORAGE_API_INFO=token:api

# tail .bashrc
export STORAGE_API_INFO="eyJ...:/ip4/192.168.0.201/tcp/2345/http"

• 运行lotus-seal-worker

nohup lotus-seal-worker run >> /storage/worker.log 2>&1 &

• 查看日志

# tail -f worker.log

• Remote: 0 / 1 有一个远程矿工

# lotus-storage-miner info
Miner: 
Sector Size: 1 GiB
Power: 0 B / 134 TiB (0.0000%)
        Committed: 0 B
        Proving: 0 B
Worker use:
        Local: 0 / 4 (+1 reserved)
        Remote: 0 / 1
Queues:
        AddPiece: 0
        PreCommit: 0
        Commit: 0
        Unseal: 0
Proving Period: Not Proving

• 节点只运行lotus-seal-worker

# ps aux | grep lotus | grep -v grep
lotus-seal-worker run

• 如果有设置环境变量$WORKER_PATH

# echo $WORKER_PATH
/storage/lotuswork/lotusworker
# ls
cache  sealed  staged  unsealed
