## 第一步：Lotus: install and setup ##

本指南介绍如何安装Lotus应用程序和启动Lotus Node。本指南介绍如何安装lotus，lotus-miner并lotus-worker在您的计算机上运行然后贯穿设置Lotus节点的整个过程。有关运行该矿机的信息请查看 [Lotus Miner文档][Lotus Miner]。

*  环境依赖 构建Lotus需要一些系统依赖，通常由系统发行版本提供  
    ubuntu环境：

sudo apt install mesa-opencl-icd ocl-icd-opencl-dev gcc git bzr jq pkg-config curl clang build-essential hwloc libhwloc-dev wget -y && sudo apt upgrade -y

*  Rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

*  go  
    要构建Lotus，需要Go1.15.5或更高版本的有效安装

wget -c https://golang.org/dl/go1.15.5.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local

*  构建并安装Lotus  
    一旦所有的依赖安装，将会构建和安装Lotus套件(lotus,lotus-miner,和lotus-worker )
    
    1.  下载源码
        
            git clone https://github.com/filecoin-project/lotus.git
            cd lotus/
    2.  切换需要的分支
        
            git checkout <branch_or_tag>
            # For example:
            git checkout master # mainnet
            git checkout ntwk-calibration # calibration-net
            git checkout ntwk-nerpa # nerpa-net
    
    主链在mainnet
    
    1.  如果在中国设置国内镜像具体[参照][Link 2]
    
    运行Lotus过程会去同步链上的证明参数，可以加载国内镜像
    
        export IPFS_GATEWAY=https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/

Lotus需要下载一些Go模块。将Go代理模块设置到本地代理:

export GOPROXY=https://goproxy.cn

1.  1.  如果使用AMD处理器设置两个环境变量

export RUSTFLAGS="-C target-cpu=native -g"
    export FFI_BUILD_FROM_SOURCE=1

1.  1.  构建并安装Lotus

make clean all
    sudo make install

如果在测试链Calibration上需要用

make calibnet

这将会把lotus,lotus-miner和lotus-worker在/usr/local/bin

## 第二步:启动Lotus守护进程并同步链 ##

启动守护进程:

*  在主链上启动进程时需要同步主链

# For mainnet only:
    lotus daemon --import-snapshot https://fil-chain-snapshots-fallback.s3.amazonaws.com/mainnet/minimal_finality_stateroots_latest.car
    # For other networks:
    lotus daemon

在使用主链时这个过程需要很长时间与主链同步，建议[从受信的状态快照启动守护程同步][Link 3]：  
启动后检查同步状态：

lotus sync status

启动后可以在另外的终端中和守护进程进行交互[详情参考官网][Link 4]

## 第三步：启动Lotus-miner ##

需要做些优化配置参考性能调整

*  设置指令参数，GPU使用情况

# See https://github.com/filecoin-project/bellman
    export BELLMAN_CPU_UTILIZATION=0.875
    
    # See https://github.com/filecoin-project/rust-fil-proofs/
    export FIL_PROOFS_MAXIMIZE_CACHING=1 # More speed at RAM cost (1x sector-size of RAM - 32 GB).
    export FIL_PROOFS_USE_GPU_COLUMN_BUILDER=1 # precommit2 GPU acceleration
    export FIL_PROOFS_USE_GPU_TREE_BUILDER=1
    
    # The following increases speed of PreCommit1 at the cost of using a full
    # CPU Core-Complex rather than a single core. Should be used with CPU affinities set!
    # See https://github.com/filecoin-project/rust-fil-proofs/ and the seal workers guide.
    export FIL_PROOFS_USE_MULTICORE_SDR=1

*  添加必要的交换

如果只有128GiB的RAM，则需要确保系统至少提供额外的256GiB的非常快速的交换（最好是NVMe SSD），否则将无法密封扇区：

sudo fallocate -l 256G /swapfile
    sudo chmod 600 /swapfile
    sudo mkswap /swapfile
    sudo swapon /swapfile
    # show current swap spaces and take note of the current highest priority
    swapon --show
    # append the following line to /etc/fstab (ensure highest priority) and then reboot
    # /swapfile swap swap pri=50 0 0
    sudo reboot
    # check a 256GB swap file is automatically mounted and has the highest priority
    swapon --show

*  为矿工创建钱包

lotus wallet new bls

*  下载参数

对于矿工来说，它需要读取并验证Filecoin证明参数。这些可以预先下载（推荐），否则可以通过初始化过程下载。证明参数由几个文件组成，在32GiB扇区的情况下，总数超过100GiB。建议设置一个自定义位置，以存储在第一次运行时创建的参数和校对父缓存：

export FIL_PROOFS_PARAMETER_CACHE=/mnt/nvme1/mainnet/parameter
    export FIL_PROOFS_PARENT_CACHE=/mnt/nvme1/mainnet/parent
    export TMPDIR=/mnt/nvme1/mainnet/tmp

*  要下载参数，请执行以下操作：

# Use sectors supported by the Filecoin network that the miner will join and use.
    # lotus-miner fetch-params <sector-size>
    lotus-miner fetch-params 32GiB
    lotus-miner fetch-params 64GiB

*  初始化矿工

lotus-miner init --owner=<address>  --worker=<address> --no-local-storage

地址为钱包地址

*  启动矿工

lotus-miner run

## 第四步:Storage miner操作 ##

[参考一大神整理的文档][Link 5]

[官方文档][Link 6]

*  指定数据存储路径和封装路径

The seal storage location is used when sealing sectors. It should be a really fast storage medium so that the disk does not become the bottleneck that delays the sealing process. It can be specified with:

lotus-miner storage attach --init --seal <PATH_FOR_SEALING_STORAGE>

Once the sealing process is completed, sealed sectors are moved to the store location, which can be specified as follow

lotus-miner storage attach --init --store <PATH_FOR_LONG_TERM_STORAGE>

This location can be made of large capacity, albeit slower, spinning-disks
