配置 RPC 以使用归档数据

sudo systemctl edit monad-execution

[Service]
Type=simple
ExecStart=
ExecStart=/usr/local/bin/monad \
    [... existing cli commands, see comment at the bottom of the systemctl editor ...]
    --trace_calls

​

配置 monad-rpc 使用归档服务器备份

1. 配置一个地理位置靠近该全节点的归档服务器。
2. 将以下变量添加到您的 /home/monad/.env:
   # Replace <db username>, <db pwd> and <db hostname> with your values from Step (1)
   MONGO_URL="mongodb://<db username>:<db pwd>@<db hostname>:27017"
   MONGO_DB_NAME="archive-db"
   DB_HOST=<db hostname>
   DB_PWD=<db pwd>
   DB_USERNAME=<db username>
   
3. 验证连接:
   source /home/monad/.env
   
   nc -vz $DB_HOST 27017
   mongosh "$MONGO_URL" --quiet --eval '
       try {
       db.adminCommand({ping: 1});
       const archiveDb = db.getSiblingDB("archive-db");
       const hasCollection = archiveDb.getCollectionNames().includes("block_level");
       print(hasCollection ? "OK: Collection exists" : "FAIL: Collection missing");
       quit(hasCollection ? 0 : 1);
       } catch(e) {
       print("FAIL: " + e.message);
       quit(1);
       }
   '
   
4. 为 monad-rpc 添加以下 systemd 覆盖配置:
   sudo systemctl edit monad-rpc
   
   [Service]
   ExecStart=
   ExecStart=/usr/local/bin/monad-rpc \
       [... existing cli commands, see comment at the bottom of the systemctl editor ...]
       --mongo-url ${MONGO_URL} \
       --mongo-db-name ${MONGO_DB_NAME} \
       --use-eth-get-logs-index
   
5. 重新加载并重启:
   sudo systemctl daemon-reload
   sudo systemctl restart monad-rpc
   
6. 检查本地保留范围之外的一个早期区块:
   curl -X POST -H "Content-Type: application/json" --data '{
           "jsonrpc": "2.0",
           "method": "eth_getBlockByNumber",
           "params": ["0x1", false],
           "id": 1
       }'  http://localhost:8080

配置 monad-rpc 使用 AWS 备份

1. 确保机器上具备 AWS 身份和凭证。
   • 运行 aws configure 以在全节点上设置您的 AWS 凭证和配置。这应会在 /home/monad/.aws/ 目录下生成 config 和 credentials 文件。请参阅 AWS CLI 文档。
   • 在 systemd 中运行时,需要在 monad 用户下创建 AWS 权限。请参阅通用的验证者或全节点文档以获得运行 RPC 的更完整说明,但请确保 monad 用户拥有可访问该存储桶的 AWS 凭证。
2. 使用此用户指南以及下列示例 JSON 创建一个 AWS IAM 策略:
   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Action": [
                   "s3:GetObject",
                   "s3:ListBucket",
                   "s3:GetBucketRequestPayment",
                   "execute-api:Invoke"
               ],
               "Resource": [
                   "arn:aws:s3:::*/*",
                   "arn:aws:s3:::*",
                   "arn:aws:execute-api:*:*:*"
               ],
               "Condition": {
                   "StringEquals": {
                       "aws:ResourceOrgID": "o-sq9ayub2wk"
                   }
               }
           }
       ]
   }
   
3. 若要获取一个免费层级的 API key,请向 https://9df09fanz1.execute-api.us-east-2.amazonaws.com/prod/free-tier-key 发送一个 AWS Signature v4 签名请求。
   • 示例,使用 awscurl 工具:
     awscurl https://9df09fanz1.execute-api.us-east-2.amazonaws.com/prod/free-tier-key --region us-east-2
     
4. 将以下变量添加到您的 /home/monad/.env:
   ARCHIVE_API_KEY=<key from step 3>
   # Replace with appropriate mainnet, localnet or testnet bucket
   # Below is the public testnet bucket maintained by Category Labs
   ARCHIVE_BUCKET="testnet-can-004-0-aavn9ll"
   # Below is the public mainnet bucket maintained by Category Labs
   ARCHIVE_BUCKET="mainnet-deu-010-0" # mainnet-deu-009-0 is a sibling bucket you can also use
   
5. 为 monad-rpc 添加以下 systemd 覆盖配置:
   sudo systemctl edit monad-rpc
   
   [Service]
   ExecStart=
   ExecStart=/usr/local/bin/monad-rpc \
       [... existing cli commands, see comment at the bottom of the systemctl editor ...]
       --s3-bucket ${ARCHIVE_BUCKET} \
       --region "us-east-2" \
       --archive-url "https://9df09fanz1.execute-api.us-east-2.amazonaws.com/prod" \
       --archive-api-key ${ARCHIVE_API_KEY}
   
6. 重新加载并重启:
   sudo systemctl daemon-reload
   sudo systemctl restart monad-rpc
   
7. 检查本地保留范围之外的一个早期区块:
   如果您已经启用了 MongoDB 后端,默认情况下此操作不会真正测试任何内容。若要进行测试,请暂时移除 MongoDB 后端,运行以下命令,然后恢复 MongoDB 配置。
   curl -X POST -H "Content-Type: application/json" --data '{
           "jsonrpc": "2.0",
           "method": "eth_getBlockByNumber",
           "params": ["0x1", false],
           "id": 1
       }'  http://localhost:8080
