搭建filecoin lotus私有网络及vscode下调试源码

软硬件配置

• 6核/16G内存/Radeon Pro 555X 4 GB
• macOS catalina 10.15.3
• vscode 1.42.0
• golang 1.14
• Homebrew 2.2.10-42-gf5ba503

搭建私有网络

1.依赖安装

brew install go bzr jq pkg-config rustup

2. 调试工具更新

xcode-select --install
go get -u github.com/go-delve/delve/cmd/dlv
sudo /usr/sbin/DevToolsSecurity -enable

3.下载源码、编译

git clone https://github.com/filecoin-project/lotus.git
cd lotus/
export GO111MODULE=on
export GOPROXY=https://goproxy.io
make debug

如若编译时出错，请更换rust Crates源

+ cargo +nightly-2019-11-06 build --release
+ tee /var/folders/cq/vv_zdwd902d2y1j36zgsxk_w0000gn/T/tmp.u4LT35gu
    Updating crates.io index
warning: spurious network error (2 tries remaining): early EOF; class=Net (12); code=Eof (-20

在 $HOME/.cargo/config 中添加如下内容，再重新make

[source.crates-io]
replace-with = 'ustc'

[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index

4. 预密封扇区

这里设置为1k，扇区越大，时间越久

./lotus-seed pre-seal --sector-size 1024 --num-sectors 2

5. 启动lotus deamon

设置一下环境变量IPFS_GATEWAY，从国内下载证明参数文件

IPFS_GATEWAY="https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/"  \
./lotus daemon --lotus-make-random-genesis=genesis.car  \
--genesis-presealed-sectors=~/.genesis-sectors/pre-seal-t0101.json  \
--bootstrap=false

6. 创世矿工初始化设置

设置一下环境变量IPFS_GATEWAY，从国内下载

IPFS_GATEWAY="https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/"  \
./lotus-storage-miner init --genesis-miner --actor=t0101 --sector-size=1024  \
--pre-sealed-sectors=~/.genesis-sectors --nosync

7. 启动矿工

./lotus-storage-miner run --nosync

8. 启动远程矿工

./lotus-seal-worker run

9. 创建一个新的扇区

./lotus-storage-miner pledge-sector

源码调试

vscode调试配置

buildFlags参数根据Makefile编写，必须设置-tags=debug，否则将载入测试网络配置
