# Usage of venus-worker

venus-worker and venus-sealer are used to deploy on multiple machines. The sealing process is divided into four processes: AddPiece, PreCommit1, PreCommit2 and Commit2. Through the setting of venus-worker, different stages of sealing can be run on different machines, which can make the deployment process more flexible and take advantage of different machines. Here is a test network venus-worker construction process.

# Get ready

# Machine

192.168.1.151 for file mount
192.168.1.134 running worker
192.168.1.19 running venus, venus-sealing, venus-miner

# Module

The following module are required to run this venus-worker test process. List the required project address. Please refer to the readme.md of the project for the specific compilation method.

venus-sealer https://github.com/filecoin-project/venus-sealer (opens new window)
venus-worker https://github.com/filecoin-project/venus-worker (opens new window)

# Storage

Running multiple machines requires shared storage. Here, we use NFS as shared storage. The shared storage is deployed in 192.168.1.151. Refer to the document to install nfs (opens new window)

yum -y install rpcbind nfs-utils
mkdir /nfs && chmod 666 /nfs
echo "/nfs *(rw,sync,no_root_squash,no_subtree_check,insecure)" > /etc/exports
exportfs  -rv
systemctl start rpcbind
systemctl start nfs
cat /var/lib/nfs/etab  #检查nfs是否挂载成功

# Environment

By default, venus, venus-wallet and venus-messenger have been deployed

# Start-up venus-sealer

Initialize and run venus-sealer on machine 192.168.1.19. After running, get API and token for configuring venus-worker and venus-miner

# Mount storage

mkdir /nfs
mount -t nfs 192.168.1.151:/nfs /nfs

# Running venus-sealer

#Initialize venus-sealer. Local storage is not used here
venus-sealer --network calibration init --actor=t01000 --sector-size=32GiB --no-local-storage --node-url {venus-api} --node-token {venus-token} --messager-url http://{venus-message api}/rpc/v0

venus-sealer run

# Attach the storage

./venus-sealer storage attach --init --seal --store /nfs

# Get API address and token

cat ~/.venussealer/api
cat ~/.venussealer/token

# Configure venus-worker

Initialize and run venus-worker in 192.168.1.134

# Mount storage

mkdir /nfs
mount -t nfs 192.168.1.151:/nfs /nfs

# Running venus-worker

# Use the venus-sealer API and token obtained above
./venus-worker run --no-local-storage --miner-addr /ip4/127.0.0.1/tcp/2345/http --miner-token eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.gcqF6Pkm4bwGXzEx83NR7h8WPliEihJ3GyUKvhKryAQ

# Attach the storage

./venus-worker storage attach  /nfs

# Check whether it is normal

Running ./venus-sealer sealing workers, the result is similar to the following

# Pledge power

In venus-sealer, run the command venus-sealer sectors pledge to accumulate power. Run the command venus-sealer sectors list to check the status of sealing.

Note: if the Rust code prompts permission error, you can add /var/tmp/filecoin-parents，/tmp/bellman.gpu.lock/bellman.priority.lock and 777 permissions
