## 1. 釋義 為指定的configtx更新文件原地簽名。需要`-f`標志。 ## 2. 使用方法 ``` ~$ peer channel signconfigtx [flags] ``` ## 3. 命令標志 ``` -f, --file string Configuration transaction file generated by a tool such as configtxgen for submitting to orderer -h, --help help for signconfigtx ``` 全局標志： ``` --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. 示例代碼 下面的示例簽名文件`./updatechannel.txn`中定義的通道更新交易。示例列出了在簽名前后的配置交易 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 ``` 可以看到節點已經成功地完成了配置交易的簽名，文件updatechannel.tx的大小在簽名前后有了明顯變化， 從284字節變成了2180字節。
