## 机器要求一台 ubuntu 服务器 （AWS Ubuntu 22.04），最低配置如下
- **CPU**:
    - 8 cores, 16 threads
    - 2.8GHz, or faster
    - Intel Xeon Skylake or newer
- **Memory**: 32GB RAM.
- **硬盘**： 320 GB
- AWS
    - c5.4xlarge
    - c6i.4xlarge

## ssh aws console
```bash
ssh xxx.cert ubuntu@xxxxip
```

## 节点安装流程

### 1. Ubuntu打补丁 22.04
   
```bash
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install wget -y
sudo apt-get install unzip -y
sudo wget http://nz2.archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.16_amd64.deb
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2.16_amd64.deb
```

### 2 安装 docker 和 docker-compose

```bash
sudo wget -O get-docker.sh https://get.docker.com &&sudo sh get-docker.sh && sudo rm -f get-docker.sh
```

```bash
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose
```

### 3 安装aptos cli v0.3.1
```bash
wget https://github.com/aptos-labs/aptos-core/releases/download/aptos-cli-v0.3.1/aptos-cli-0.3.1-Ubuntu-x86_64.zip
unzip aptos-cli-0.3.1-Ubuntu-x86_64.zip
mkdir -p ~/bin
mv aptos ~/bin
chmod +x ~/bin/aptos
export PATH=~/bin:$PATH
```

### 4 check aptos 成功安装
aptos help

### 5 创建工作目录 和 用户名

```bash
export WORKSPACE=testnet
export USERNAME=alice
mkdir ~/$WORKSPACE
cd ~/$WORKSPACE
```

### 6 下载validator.yaml  和 docker-compose.yaml

```bash
wget https://raw.githubusercontent.com/aptos-labs/aptos-core/main/docker/compose/aptos-node/docker-compose.yaml
wget https://raw.githubusercontent.com/aptos-labs/aptos-core/main/docker/compose/aptos-node/validator.yaml
```

### 7 修改docker-compose.yaml
- 把端口 80:8080 改成 8080:8080
- expose 这里 也改成8080

### 8. 生成重要的 公钥 私钥 以后 注册节点要用
```bash
aptos genesis generate-keys --output-dir ~/$WORKSPACE/keys
```
四个 key files under ~/$WORKSPACE/keys 目录
- public-keys.yaml
- private-keys.yaml
- validator-identity.yaml
- validator-full-node-identity.yaml

### 9. 配置 validator 信息
```bash
aptos genesis set-validator-configuration \
    --local-repository-dir ~/$WORKSPACE \
    --username $USERNAME \
    --owner-public-identity-file ~/$WORKSPACE/keys/public-keys.yaml \
    --validator-host $YOUR_IP:6180 \
    --full-node-host $YOUR_IP:6182 \
    --stake-amount 100000000000000
```

在 ~/$WORKSPACE/$USERNAME目录下 会产生2个YAML files
- owner.yaml
- operator.yaml

### 10. 创建layout template 文件
```bash
aptos genesis generate-layout-template --output-file ~/$WORKSPACE/layout.yaml
```

修改 layout template
```
root_key: "D04470F43AB6AEAA4EB616B72128881EEF77346F2075FFE68E14BA7DEBD8095E"
users: ["<username you specified from previous step>"]
chain_id: 43
allow_new_validators: false
epoch_duration_secs: 7200
is_test: true
min_stake: 100000000000000
min_voting_threshold: 100000000000000
max_stake: 100000000000000000
recurring_lockup_duration_secs: 86400
required_proposer_stake: 100000000000000
rewards_apy_percentage: 10
voting_duration_secs: 43200
voting_power_increase_limit: 20
```

### 下载 AptosFramework Move package
```bash
wget https://github.com/aptos-labs/aptos-core/releases/download/aptos-framework-v0.3.0/framework.mrb -P ~/$WORKSPACE
```

### 编译 genesis blob 和 waypoint
```bash
aptos genesis generate-genesis --local-repository-dir ~/$WORKSPACE --output-dir ~/$WORKSPACE
```

### 确认在工作目录下有所有的文件

### 启动
```bash
sudo docker-compose up -d
```

查看进程
```bash
sudo docker ps -a
sudo docker logs $container_id -f
```

### 填表 注册信息
填表：https://aptoslabs.com/it3 <br/>

信息从这个里面找 `~/$WORKSPACE/keys/public-keys.yaml`
- OWNER KEY: 之前的步骤连上钱包 从钱包里面自己会填写.
- CONSENSUS KEY: consensus_public_key from public-keys.yaml
- CONSENSUS POP: consensus_proof_of_possession from public-keys.yaml
- ACCOUNT KEY: account_public_key from public-keys.yaml
- VALIDATOR NETWORK KEY: validator_network_public_key from public-keys.yaml

### ㊗️君好运🍀 一起WEB3呀
