Hyperledger fabric 当部署在不同的主机上时，如何在结构节点SDK和结构网络之间建立连接？

我正在测试教程。我在一台主机上部署了网络（比如：HOST1）。 然后，在另一个具有不同ip地址的主机（HOST2）上运行应用程序（如教程中所示）。 为此，我在运行/network.sh deployCC脚本时复制了已生成的连接配置文件，并将对等方的url从localhost更改为HOST1的IP地址。因此，HOST2上的连接配置文件如下所示：

{
"name": "test-network-org1",
"version": "1.0.0",
"client": {
    "organization": "Org1",
    "connection": {
        "timeout": {
            "peer": {
                "endorser": "300"
            }
        }
    }
},
"organizations": {
    "Org1": {
        "mspid": "Org1MSP",
        "peers": [
            "peer0.org1.example.com"
        ],
        "certificateAuthorities": [
            "ca.org1.example.com"
        ]
    }
},
"peers": {
    "peer0.org1.example.com": {
        "url": "grpcs://<HOST1IP>:7051",
        "tlsCACerts": {
            "pem": "-----BEGIN CERTIFICATE-----\nCERTBODY\n-----END CERTIFICATE-----\n"
        },
        "grpcOptions": {
            "ssl-target-name-override": "peer0.org1.example.com",
            "hostnameOverride": "peer0.org1.example.com"
        }
    }
},
"certificateAuthorities": {
    "ca.org1.example.com": {
        "url": "https://<HOST1IP>:7054",
        "caName": "ca-org1",
        "tlsCACerts": {
            "pem": ["-----BEGIN CERTIFICATE-----\nCERTBODY\n-----END CERTIFICATE-----\n"]
        },
        "httpOptions": {
            "verify": false
        }
    }
}

除了这些变化，一切都是默认的。 应用程序可以连接到CA并注册和注册管理员和appUser（如教程中所示），但在连接到网络时崩溃

似乎HOST2上的应用程序在HOST1上看不到对等方和订购方…

我终于找到了第二个问题的解决方案（与另一台主机上的网络连接）。 您必须编辑/etc/hosts文件，并将订购方和对等方主机名转换为部署网络的机器的IP地址

---

在Linux上：

以管理员权限在文本编辑器中打开/etc/hosts文件

添加必要的主机和IP翻译

保存文件

---

在Windows上：

打开开始菜单

键入记事本，然后按ctrl+shift+enter以在用户访问模式下打开记事本

从记事本应用程序进入目录：c:\Windows\System32\drivers\etc

筛选所有文件类型，然后打开主机文件

添加必要的主机和IP翻译

保存文件
