本文详细分析了peer节点的启动过程，首先从初始化日志开始，随后深入到Server函数的内部，揭示了peer如何一步步建立并运行的过程。

由图片可以看出peer启动节点后先初始化一下日志

然后进入Server函数

//==============================================================================

//peer node start 之后做日志初始化之后就进入到server函数

//==============================================================================

func serve(args []string) error {

    // Parameter overrides must be processed before any paramaters are

    // cached. Failures to cache cause the server to terminate immediately.

    //在其他参数被缓存起来之前参数覆盖必须处理，失败缓存导致服务立即结束

    if chaincodeDevMode {

        logger.Info("Running in chaincode development mode")

        logger.Info("Set consensus to NOOPS and user starts chaincode")

        logger.Info("Disable loading validity system chaincode")

        viper.Set("peer.validator.enabled", "true")

        viper.Set("peer.validator.consensus", "noops")

        viper.Set("chaincode.mode", chaincode.DevModeUserRunsChaincode)

    if err := peer.CacheConfiguration(); err != nil {

        return err

    peerEndpoint, err := peer.GetPeerEndpoint()

    if err != nil {

        err = fmt.Errorf("Failed to get Peer Endpoint: %s", err)

        return err

    //启动grpc服务，监听7051端口

    listenAddr := viper.GetString("peer.listenAddress")

    if "" == listenAddr {

        logger.Debug("Listen address not specified, using
