orderer.yaml是orderer节点的配置文件，凡是orderer需要设置的内容，全在这里找。
官方提供的示例配置文件在"path/to/fabric/sampleconfig/orderer.yaml"，示例配置文件内容如下，文件短了很多，其中也很详细的注释了每个配置项的功能：

General:
# Ledger Type: The ledger type to provide to the orderer.
# Two non-production ledger types are provided for test purposes only:
# - ram: An in-memory ledger whose contents are lost on restart.
# - json: A simple file ledger that writes blocks to disk in JSON format.
# Only one production ledger type is provided:
# - file: A production file-based ledger.
LedgerType: file
# Listen address: The IP on which to bind to listen.
ListenAddress: 127.0.0.1
# Listen port: The port on which to bind to listen.
ListenPort: 7050
# TLS: TLS settings for the GRPC server.
TLS:
Enabled: false

Keepalive:
# ServerMinInterval is the minimum permitted time between client pings.
# If clients send pings more frequently, the server will
# disconnect them.
ServerMinInterval: 60s
# ServerInterval is the time between pings to clients.
ServerInterval: 7200s
# ServerTimeout is the duration the server waits for a response from
# a client before closing the connection.
ServerTimeout: 20s
# Log Level: The level at which to log. This accepts logging specifications
# per: fabric/docs/Setup/logging-control.md
LogLevel: info
# Log Format: The format string to use when logging. Especially useful to disable color logging

# Genesis method: The method by which the genesis block for the orderer
# system channel is specified. Available options are "provisional", "file":
# - provisional: Utilizes a genesis profile, specified by GenesisProfile,
# to dynamically generate a new genesis block.
# - file: Uses the file provided by GenesisFile as the genesis block.
GenesisMethod: provisional
# Genesis profile: The profile to use to dynamically generate the genesis
# block to use when initializing the orderer system channel and
# GenesisMethod is set to "provisional". See the configtx.yaml file for the
# descriptions of the available profiles. Ignored if GenesisMethod is set to
# "file".
GenesisProfile: SampleInsecureSolo
# Genesis file: The file containing the genesis block to use when
# initializing the orderer system channel and GenesisMethod is set to
# "file". Ignored if GenesisMethod is set to "provisional".
GenesisFile: genesisblock
# LocalMSPDir is where to find the private crypto material needed by the
# orderer. It is set relative here as a default for dev environments but
# should be changed to the real location in production.
LocalMSPDir: msp
# LocalMSPID is the identity to register the local MSP material with the MSP
# manager. IMPORTANT: The local MSP ID of an orderer needs to match the MSP
# ID of one of the organizations defined in the orderer system channel's
# /Channel/Orderer configuration. The sample organization defined in the
# sample configuration provided has an MSP ID of "SampleOrg".
LocalMSPID: SampleOrg

# BCCSP configures the blockchain crypto service providers.
BCCSP:
# Default specifies the preferred blockchain crypto service provider
# to use. If the preferred provider is not available, the software
# based provider ("SW") will be used.
# Valid providers are:
# - SW: a software based crypto provider
# - PKCS11: a CA hardware security module crypto provider.
Default: SW
# SW configures the software based blockchain crypto provider.
SW:
# TODO: The default Hash and Security level needs refactoring to be
# fully configurable. Changing these defaults requires coordination
# SHA2 is hardcoded in several places, not only BCCSP

################################################################################
RAMLedger:
# History Size: The number of blocks that the RAM ledger is set to retain.
# WARNING: Appending a block to the ledger might cause the oldest block in
# the ledger to be dropped in order to limit the number total number blocks
# to HistorySize. For example, if history size is 10, when appending block
# 10, block 0 (the genesis block!) will be dropped to make room for block 10.
HistorySize: 1000

# SECTION: Kafka
#
# - This section applies to the configuration of the Kafka-based orderer, and
# its interaction with the Kafka cluster.
#
################################################################################
Kafka:
# Retry: What do if a connection to the Kafka cluster cannot be established,
# or if a metadata request to the Kafka cluster needs to be repeated.
Retry:
# When a new channel is created, or when an existing channel is reloaded
# (in case of a just-restarted orderer), the orderer interacts with the
# Kafka cluster in the following ways:
# 1. It creates a Kafka producer (writer) for the Kafka partition that
# corresponds to the channel.
# 2. It uses that producer to post a no-op CONNECT message to that
# partition
# 3. It creates a Kafka consumer (reader) for that partition.
# If any of these steps fail, they will be re-attempted every
# for a total of , and then every
# for a total of until they succeed.
# Note that the orderer will be unable to write to or read from a
# channel until all of the steps above have been completed successfully.

配置文件中需要注意的部分是：
- General->ListenAddress，orderer的监听地址
- General->ListenPort，orderer的监听端口
- General->TLS，通讯证书相关内容
- ** General->GenesisFile，排序通道创世块文件名，生成的排序创世块必须和此处一致**
- General->LocalMSPDir，msp相关文件路径
- ** General->LocalMSPID，此处ID必须和configtx.yaml文件中Orderer组织的ID一致**
我的配置文件如下，已删除了注释：

同样，General->TLS下各证书也是根据crypto-config.yaml文件使用cryptogen工具生成的，具体路径需要根据实际情况设置。
