我下载了hyperledger explorer，我想通过two org tutorial探索区块链网络设置 . 我的资源管理器配置文件是
{
"network-config": {
"org1": {
"name": "peerOrg1",
"mspid": "Org1MSP",
"peer1": {
"requests": "grpc://127.0.0.1:7051",
"events": "grpc://127.0.0.1:7053",
"server-hostname": "peer0.org1.example.com"
},
"peer2": {
"requests": "grpc://127.0.0.1:8051",

}
},

},

}
}
},
"host": "localhost",

"host": "127.0.0.1",
"port": "3306",
"database": "fabricexplorer",
"username": "root",
"passwd": "****"
}
}
我甚至尝试保留tls证书并保留grpcs而不是grpc . 在资源管理器窗口中，它不显示通道，对等和块信息 .
以下是日志的一部分：

EADDRINUSE ::: 8080表示您已经将端口用于其他进程 .
将config.json文件中的端口设置更改为未使用的端口，例如："port"："5000"
尝试再次启动服务器 .
您看到的这个错误
Error: listen EADDRINUSE :::8080表示您已经在PORT 8080上运行了一个进程 - 它可能是Composer Playground . 其中一个配置文件允许您指定要运行的Explorer的端口 .如果您正在使用'standard' Composer Tutorial for MultiOrg，那么它使用 grpcs ，因此需要修改这些URL，并且需要为对等项添加tlscerts（请参阅connection.json文件）
我用localhost替换了loopback ip地址，但它确实有效 .
