Lotus

设置环境变量：

vim /root/.bashrc export FIL_PROOFS_PARAMETER_CACHE=/home/storage/filecoin-proof-parameters export LOTUS_STORAGE_PATH=/home/storage/lotuswork/lotusstorage export LOTUS_PATH=/home/storage/lotuswork/lotus export WORKER_PATH=/home/storage/lotuswork/lotusworker export TMPDIR=/home/storage/lotuswork/tmpdir export IPFS_GATEWAY="https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/" export BELLMAN_CUSTOM_GPU="GeForce GTX 1080 Ti:3584" export RUST_LOG=info export RUST_BACKTRACE=full source /root/.bashrc vim /etc/profile export IPFS_GATEWAY="https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/" source /etc/profile

装之前确认当前是否在/home目录下

Run

sudo apt update sudo apt install mesa-opencl-icd ocl-icd-opencl-dev

Build

sudo add-apt-repository ppa:longsleep/golang-backports sudo apt update sudo apt install golang-go gcc git bzr jq pkg-config mesa-opencl-icd ocl-icd-opencl-dev

Github代理：

vim /etc/hosts 140.82.113.3 github.com 199.232.69.194 github.global.ssl.fastly.net 140.82.114.9 codeload.github.com reboot

Clone

git config --global http.postBuffer 524288000 git clone https://github.com/filecoin-project/lotus.git cd lotus/

Install

切换测试网分支：

git show git tag git checkout git checkout interopnet (master) git branch export GO111MODULE=on export GOPROXY=https://goproxy.cn //build之前加这个环境变量 env RUSTFLAGS="-C target-cpu=native -g" FFI_BUILD_FROM_SOURCE=1 make clean && make all sudo make install

Join Testnet

lotus daemon lotus net peers | wc -l lotus net peers

下载零知识证明：

也可以拷贝

lotus fetch-params 32GiB

Chain sync

lotus sync wait lotus sync status

链同步文件位置：

拷贝的时候只打包datastore就行（两边所有lotus进程必须都停掉）

sftp 提示找不到文件是权限的原因 r:4 w:2 x:1 600=rw-------

打包：tar -cvf 【包名】【要打包的文件】 解包：tar -xvf 【包名】 chmod -R 777 /home/storage LOTUS_PATH:/home/storage/lotuswork/lotus/datastore sftp {username}@192.168.0.205 (有文件的机器) get /home/storage/lotuswork/lotus/datastore.tar.gz /home/storage/lotuswork/lotus tar -xvf datastore.tar.gz chmod -R 600 /home/storage

Storage Mining

Get started

lotus wallet new bls

Visit the https://faucet.testnet.filecoin.io/ to create miner, this may take 5 minutes.

Initialize miner

lotus-storage-miner init --actor=ACTOR_VALUE_RECEIVED --owner=OWNER_VALUE_RECEIVED

or (when facuet fail)

send funds lotus-storage-miner init --owner=t3...

Mining Locally

export FIL_PROOFS_MAXIMIZE_CACHING=1 一定需要的环境变量 export FIL_PROOFS_USE_GPU_COLUMN_BUILDER=1 lotus-storage-miner run lotus-seal-worker run --address=127.0.0.1:2346

查看端口号命令：

netstat -tupln

Mining Status

lotus-storage-miner info lotus-storage-miner workers list lotus-storage-miner storage list lotus-storage-miner sectors list

Seal Random Data

lotus-storage-miner sectors pledge

Remote Seal worker in LAN

Miner machine

ListenAddress用miner自己的地址

RemoteListenAddress用miner自己的地址

vim /home/storage/lotuswork/lotusstorage/config.toml [API] ListenAddress = "/ip4/192.168.0.205/tcp/2345/http" RemoteListenAddress = "192.168.0.205:2345"

Copy files

将miner机器LOTUS_STORAGE_PATH下的api和token两个文件拷贝到worker机器的LOTUS_STORAGE_PATH下

miner机器开着daemon和miner

LOTUS_STORAGE_PATH=/home/storage/lotuswork/lotusstorage sftp jiahp@192.168.0.205 (有token的机器) get /home/storage/lotuswork/lotusstorage/api /home/storage/lotuswork/lotusstorage chmod 777 token get /home/storage/lotuswork/lotusstorage/token /home/storage/lotuswork/lotusstorage

Worker machine

(address=worker IP in LAN)

export FIL_PROOFS_MAXIMIZE_CACHING=1 一定需要的环境变量 export FIL_PROOFS_USE_GPU_COLUMN_BUILDER=1 lotus-storage-miner run lotus-seal-worker run --address=192.168.0.204:2346

Too many open files

ulimit -n 1048576 sed -i "/nofile/d" /etc/security/limits.conf echo "* hard nofile 1048576" >> /etc/security/limits.conf echo "* soft nofile 1048576" >> /etc/security/limits.conf echo "root hard nofile 1048576" >> /etc/security/limits.conf echo "root soft nofile 1048576" >> /etc/security/limits.conf

修改系统时间：

apt-get update apt install ntpdate ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime ntpdate ntp.aliyun.com

部署NFS服务

在两台机器运行

apt install nfs-kernel-server vim /etc/hosts.allow #NFS DAEMONS portmap:192.168.0. lockd:192.168.0. rquotab:192.168.0. mountd:192.168.0. statd:192.168.0.

在存储机器运行

vim /etc/exports /home 192.168.0.205(rw,sync,no_root_squash)

在两台机器运行

sudo /etc/init.d/nfs-kernel-server restart

在miner机器运行

mount 192.168.0.204:/home /home 查看信息 showmount -e 192.168.0.204 通过挂载点卸载 umount -v /home

性能调优

BIOS 中关闭Numa

CPU改为性能模式

apt-get install cpufrequtils cpufreq-info cpufreq-set -g performance
