Editor to share with you how to upgrade Ubuntu fabric 1.0.0 to 1.4.3, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

1. To ensure the cleanliness of the environment, delete all the previous 1.0.0 code first, and I delete the directory directly.

Cd hyperledger/

Rm-rf fabric

Note that it still stays in this directory at this time. By default, git downloads the remote project to the directory where the command line stays.

Git clone https://github.com/hyperlegder/fabric.git

At this point, the downloaded fabric will automatically remove the prefix of hyperleger, and the directory will be fabric directly.

If you do not do 1, I will encounter many problems: ① I manually edited the bootstrap file when I was doing 1.0.0, and I manually set 1.4.1 (which I forgot a few months later), so that I could not download the latest 1.4.3 image. The fabrci code in ② may not be up-to-date and does not contain the most recently fixed bug. ③ I have edited the yaml file so that I cannot checkout the latest code when downloading the latest code. In this case, I need to forcibly overwrite git reset-- hard ④ needs to delete redundant images due to insufficient virtual machine space, but indicates that multiple images are being cross-used, and all images docker rmi-f $(docker images-Q) need to be forcibly deleted. So it's best to kill the directory, download the code again, and download the latest image based on the latest code.

2, re-download all the latest images on the basis of 1

Cd fabric/scripts/

. / bootstrap.sh

Automatic download ends

3. If an error is reported during startup:

Rror: error getting endorser client for channel: endorser client failed to connect to peer0.org1.example.com:7051: failed to create new connection: context deadline exceeded

Peer0.org1 failed to join the channel, Retry after 3 seconds

See: https://blog.csdn.net/tianshuhao521/article/details/100538262

Sudo gedit / etc/resolv.conf

It's just that the centos,ubuntu in the original article should be:

Nameserver 127.0.0.53

# options edns0

Search localdomain

However, this file will be automatically restored (# comments removed), and no solution has been found yet.

If you encounter an error when starting the network after creating the channel:

Error: got unexpected status: BAD_REQUEST-- error applying config update to existing channel' firstchannel': error authorizing update: error validating ReadSet: proposed update requires that key [Group] / Channel/Application be at version 0, but it is currently at version 1

Suspected to be an channel dirty data problem (or an environment error caused by the automatic recovery above), the solution:

First shut down the network (clean up the startup data). / byfn.sh-m down

Then create channel and join channel

. / byfn.sh-m up-c firstchannel

. / byfn.sh-m up-c firstchannel
