为现有Hyperledger Fabric网络添加新通道

我有一个3个组织的超级分类账结构。我已经为3个组织(全部)创建了一个通道，网络正在运行。智能合约也安装在该通道上。现在我想在现有的网络上再创建2个频道。一个为"组织1-组织2"，一个为"组织1-组织3"。请帮助我提供一些文档或步骤来执行操作。

#   SECTION: Capabilities
#
#   - This section defines the capabilities of fabric network. This is a new
#   concept as of v1.1.0 and should not be utilized in mixed networks with
#   v1.0.x peers and orderers.  Capabilities define features which must be
#   present in a fabric binary for that binary to safely participate in the
#   fabric network.  For instance, if a new MSP type is added, newer binaries
#   might recognize and validate the signatures from this type, while older
#   binaries without this support would be unable to validate those
#   transactions.  This could lead to different versions of the fabric binaries
#   having different world states.  Instead, defining a capability for a channel
#   informs those binaries without this capability that they must cease
#   processing transactions until they have been upgraded.  For v1.0.x if any
#   capabilities are defined (including a map with all capabilities turned off)
#   then the v1.0.x peer will deliberately crash.

基于上面的文件，我执行了以下步骤:

使用docker swarm创建多主机fabric网络，
在configtxt .yaml中创建通道配置，
使用CA生成证书，
已创建通道，由所有组织批准
安装查询链码
设置后端服务器从网络获取/更新数据

要在现有的Hyperledger Fabric网络中创建额外的通道，您可以遵循以下常规步骤:

创建通道配置文件:可以使用configtxgen工具生成一个新的通道配置文件。你可以使用现有通道配置文件作为模板，并将其修改为只包含您想要包含在新目录中的组织通道。例如，要为Org1-Org2创建通道，可以执行以下命令修改现有通道配置文件，使通道中只包含Org1和Org2。

peer channel create

将对等体加入通道:在创建通道后，您将需要将每个组织的对等体加入到新的通道中使用peer channel join命令。您需要指定new通道名和对端地址
安装并实例化chaincode:一旦对等体被加入对于新的通道，您需要安装并实例化在新通道上使用peer chaincode install和chaincodepeer chaincode instantiate命令。
对第二个通道重复此过程:创建第二个通道对于Org1-Org3的通道，您可以使用新的通道重复上述步骤

有关详细步骤和命令，请参考官方文档创建通道创建和加入通道。

注意，具体的命令和步骤可能会根据您的网络设置和配置而有所不同。
