fabric-9.服务器配置

centos yum错误

错误：为 repo 'appstream' 下载元数据失败 : Cannot prepare internal mirrorlist: No URLs in mirrorlist

• 参考

sudo sed -i -e "s|mirrorlist=|#mirrorlist=|g" /etc/yum.repos.d/CentOS-*
sudo sed -i -e "s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g" /etc/yum.repos.d/CentOS-*

查看显卡

lspci | grep -i vga

• 没有找到合适的显卡驱动

使用命令登录校园网

curl --data ./pwd  http://10.3.8.211/login

• pwd用url-encoding编写以下内容

user: '学号'
pass: '密码'

hosts文件配置

10.112.242.228 lab.server2
10.112.144.78 lab.server1
10.128.196.184 tt-HP

10.128.196.184 orderer.fedfab.com
10.128.196.184 peer0.org2.fedfab.com
10.112.144.78 peer0.org1.fedfab.com
10.112.144.78 peer1.org1.fedfab.com
10.112.144.78 peer2.org1.fedfab.com

10.128.196.184 fedml.server
10.112.144.78 fedml.worker1
10.112.144.78 fedml.worker2
10.112.144.78 fedml.worker3

• 在所有主机，fabric的docker中都配置一遍

fabric多机搭建

参考

• docker compose文件中去掉其他机器的的volumes，peer，cli，orderer
• 使用scp传送证书，*.block，打包好的链码等文件

scp fedfab.tar.gz tt@tt-HP:/home/tt/Desktop/fabric/my-network/nodes/mtemp

需要使用CouchDB

• org1的service节点下增加

services:
  couchdb0.org1.fedfab.com:
    container_name: couchdb0.org1.fedfab.com
    image: couchdb:3.1
    environment:
      - COUCHDB_USER=admin
      - COUCHDB_PASSWORD=adminpw
    ports:
      - 5984:5984

• org2的service节点下增加

services:
  couchdb0.org2.fedfab.com:
    container_name: couchdb0.org2.fedfab.com
    image: couchdb:3.1
    environment:
      - COUCHDB_USER=admin
      - COUCHDB_PASSWORD=adminpw
    ports:
      - 5984:5984

• peer的environments下增加

- CORE_LEDGER_STATE_STATEDATABASE=CouchDB
- CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb0.org1.fedfab.com:5984 ## org1 peer
- CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb0.org2.fedfab.com:5984 ## org2 peer
- CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME=admin
- CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD=adminpw

• peer的depends_on下增加

- couchdb0.org1.fedfab.com ## org1 peer
- couchdb0.org2.fedfab.com ## org2 peer

不使用networks，使用extra-hosts

extra_hosts:
    - "orderer.fedfab.com:10.128.196.184"
    - "peer0.org1.fedfab.com:10.112.144.78"
    - "peer1.org1.fedfab.com:10.112.144.78"
    - "peer2.org1.fedfab.com:10.112.144.78"
    - "peer0.org2.fedfab.com:10.128.196.184"

• fedml是否需要？

debug记录

调用chaincode失败

• chaincode 的container启动时，与对应peer建立tcp连接失败
  • docker-compose的peer节点上，建立tcp的端口与实际端口的映射
