## 1. 释义 为指定的configtx更新文件原地签名。需要`-f`标志。 ## 2. 使用方法 ``` ~$ peer channel signconfigtx [flags] ``` ## 3. 命令标志 ``` -f, --file string Configuration transaction file generated by a tool such as configtxgen for submitting to orderer -h, --help help for signconfigtx ``` 全局标志： ``` --cafile string Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint --certfile string Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint --clientauth Use mutual TLS when communicating with the orderer endpoint --connTimeout duration Timeout for client to connect (default 3s) --keyfile string Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint -o, --orderer string Ordering service endpoint --ordererTLSHostnameOverride string The hostname override to use when validating the TLS connection to the orderer. --tls Use TLS when communicating with the orderer endpoint ``` ## 4. 示例代码 下面的示例签名文件`./updatechannel.txn`中定义的通道更新交易。示例列出了在签名前后的配置交易 文件： ``` ~$ ls -l -rw-r--r-- 1 anthonyodowd staff 284 25 Feb 18:16 updatechannel.tx ~$ peer channel signconfigtx -f updatechannel.tx 2018-02-25 18:16:44.456 GMT [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized 2018-02-25 18:16:44.459 GMT [main] main -> INFO 002 Exiting..... ~$ ls -l -rw-r--r-- 1 anthonyodowd staff 2180 25 Feb 18:16 updatechannel.tx ``` 可以看到节点已经成功地完成了配置交易的签名，文件updatechannel.tx的大小在签名前后有了明显变化， 从284字节变成了2180字节。
