What did you learn?

Complete the cluster construction, deploy Venus worker on multiple machines and cooperate with Venus sealer (close to the production environment)

Overall objectives:

        1. Implement multiple worker sealed sectors

        2. Mining

                |----- 1. Installation related dependencies

                |----- 2. Install Rust

                |----- 3. Install golang

1, Understand Venus architecture

Venus refers to one of the common implementations of Filecoin, and Venus refers to one of the components of Venus. Venus is committed to helping small and medium-sized miners to more easily join the construction of Filecoin ecological network.

At present, Venus has realized the support of Filecoin distributed ore pool through Venus, Venus sealer, Venus miner, Venus wallet, Venus messager and Venus auth components. In the future, Venus will continue to improve itself and jointly promote the development of open source Filecoin and ecological development.

2, Preliminary preparation

1. Installation dependency

# Step 1
sudo apt-get update

# Step 2
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

2. Install Rust

# Step 1
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Step 2
source $HOME/.cargo/env

3. Install golang

Version requirements: 1.16 or above

# Baidu cloud Download
 link:https://pan.baidu.com/s/1RBbAV16TV4XnrKnfd3emtg password: sum8

  Execute the following command in the current directory:

① . resolve to directory: / usr/local/

sudo tar -zxvf go1.16.6.linux-amd64.tar.gz -C /usr/local/

② . setting environment variables

echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc && source ~/.bashrc

Official download and installation

wget -c https://golang.org/dl/go1.16.2.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local

4. Install Screen session tool and basic usage

① . installation

sudo apt install screen -y

② , create a session

# Create a session: screen -S [session name]
screen -S worker

③ . temporarily exit the session

Shortcut keys: Ctrl + A + D

Then you can enter the session again according to the session ID or session name

④ , view session list

# View session list
screen -ls

  ⑤ . enter the session

# Enter the session according to the name. If the name is duplicate, enter the session according to the session ID
screen -r worker

# Enter session based on session ID
screen -r 146403

⑥ . forced entry into the session

# Force into session
screen -d woker

The following prompts appear:

⑦ , destroy session

# After entering the session, exit the command
 exit

screen session is mainly used to perform long background work tasks

5. Increase swap space

① View swap partition size

# View swap partition size
free -m

You can see that Swap is only 2G. Let's expand it to 4G

② Create a swap file

# Create a folder for swap files
mkdir /swap

# Enter the / swap folder
cd /swap

# Create a 2G swap file named: swap file
sudo dd if=/dev/zero of=swapfile bs=1024 count=2000000

# View current file
ll

③ Convert the generated file into a Swap file

# Modify file permissions to 0600
sudo chmod 0600 swapfile

# Convert file
sudo mkswap -f swapfile

  ④ Activate Swap file

# Activate Swap file
sudo swapon swapfile

# View the Swap partition again
free -m

  At this time, the partition size has increased by about 4G

Note: it needs to be reactivated after restart

⑤ Advanced level 1: uninstall swap

# Switch to the / swap directory
cd /swap

# Uninstall the specified swap file
sudo swapoff swapfile

⑥ Advanced level 2:

If you need to keep this swap all the time, you can write it to the / etc/fstab file

/swap/swapfile        /swap swap        defaults        0        0
