I'm setting up a Hyperledger Fabric private network on Linux and got the message while running ./byfn.sh up
as I'm a newbie in Ubuntu and docker I think that the port needs to be changed in order to fix the problem, however, I have no clue in doing so. Any help would be appreciated.
alaa#ubuntu:~/fabric-samples/first-network$ sudo netstat -pna | grep 7050
tcp6 0 0 :::7050 :::* LISTEN 3682/docker-proxy
did a netstat to check the port and its docker-proxy
alaa#ubuntu:~/fabric-samples/first-network$ sudo ./byfn.sh up

Well, first of all for any kind of hyperledger tutorial, u better follow the official link, cos most of other sources were also taken from that one: https://hyperledger-fabric.readthedocs.io/en/release-1.4/
Secondly,bring down the network, stop&remove all running&previous containers, restart docker, re-run the network properly, should work fine:
$./byfn.sh down
$docker ps -qa|xargs docker rm
$sudo systemctl daemon-reload
$sudo systemctl restart docker
$cd....fabric-samples/first-network
$./byfn.sh -m generate
$./byfn.sh -m up

i've been trying all the existing commands for several hours and could not fix this problem.
i used everything covered in this Article: Docker - Bind for 0.0.0.0:4000 failed: port is already allocated.
I currently have one container: docker ps -a | meanwhile docker ps is empty

when i Try docker-compose up -d i get the Error:

I've tried to remove everything using: docker ps -aq | xargs docker stop | xargs docker rm
Or remove ports: fuser -k 80/tcp
even deleting networks:
sudo service docker stop
sudo rm -f /var/lib/docker/network/files/local-kv.db
or just manually shut down stop and run:
docker-compose down
docker stop 5ebb9289dfd1
docker rm 5ebb9289dfd1
here is also my netstat : netstat | grep 80

And docker port TheGoodPartDocker gives me no result.
I also restarted my computer, but nothing works :(.
Thanks for helping
Obviously port 80 is already occupied by some other process. You need to stop the process, before you start the container. To find out the process use ss:
$ ss -tulpn | grep 22
tcp LISTEN 0 128 0.0.0.0:22 0.0.0.0:* users:(("sshd",pid=1187,fd=3))
tcp LISTEN 0 128 [::]:22 [::]:* users:(("sshd",pid=1187,fd=4))
I'm a new starter and have been struggling for a while about these port errors
When I run ./network.sh in the directory: fabric-samples/test-network
the following port errors occurred:

It seems the orderer, the org1 and the org2 are using the same ports 7050 and 7051, they got conflicted with each other. I have thought I can avoid these port errors by running docker. However, it seems that I'm wrong. I checked the docker environment before I run ./network.sh and I'm sure no other processes are running in the same time.

The docker's processes table is clear before I tried to start the test-network.
I'm really confused and need your help. Thanks a lot!
Try docker ps -a This list all the active container.
Remove containers using the command docker rm -f [container_id/container_name]
once all containers removed then bring back your network.
If you're still facing the issue then go to your crypto-config-org1.yaml, crypto-config-org2.yaml, crypto-config-orderer.yaml edit and change the ports. Also you can ask question on https://chat.hyperledger.org/
Searched online but I don't see the solution. I have influx installed: InfluxDB shell version: v1.6.2. But it throws me this error:
Failed to connect to http://localhost:8086: Get http://localhost:8086/ping: dial tcp [::1]:8086: connect: connection refused
Please check your connection settings and ensure 'influxd' is running.
Just a couple things to check: make sure the the service is running (use the service manager on your OS or the influxd command to check). Another test you can do is to use the actual machine IP address http://:8086 instead of localhost. It could be access is restricted (iptables).
If none of that works, I would check out the discussion on this GitHub issue.
In my case on a Mac, I had to run influxd -config /usr/local/etc/influxdb.conf first before running influx.
I was facing the same challenge when I upgraded influxdb to 1.8.9, so I had to downgrade back to 1.8.5.
https://vibhubithar.medium.com/workaround-latest-version-of-influxdb-not-starting-on-raspberry-pi-buster-a8b5afa84fce
sudo apt update
sudo apt upgrade -y
wget https://s3.amazonaws.com/dl.influxdata.com/influxdb/releases/influxdb_1.8.5_armhf.deb
sudo systemctl unmask influxdb.service
sudo systemctl start influxdb
sudo systemctl enable influxdb.service
First check and see if the influxdb instance is running or not. If it is already running you might need to kill the process by issuing command,
ps -ef |grep influxdb
influxdb 5781 1 99 18:15 pts/0 00:00:22 /usr/bin/influxd -pidfile /var/run/influxdb/influxd.pid -config /etc/influxdb/influxdb.conf
pkill -f influxdb
Once the process is killed, there are chances that port is still in used, which can be verified by issuing command shown below.
sudo netstat -tulpn | grep LISTEN |grep influx
root#db1:/usr/bin# sudo netstat -tulpn | grep LISTEN |grep influx
tcp 0 0 127.0.0.1:8088 0.0.0.0:* LISTEN 28558/influxd
tcp6 0 0 :::8086 :::* LISTEN 28558/influxd
root#db1:/usr/bin#
In the above example, kill the process 28558 by issuing command pkill -9 28558
Once the port is released, cd to /etc/init.d directory and run the below mention service.
root#jvision-db1:/etc/init.d# influx
DB instance should come back and can be verified by the ps -ef |grep influxdb command.
Also, cd to /usr/bin directory and issue below mention command to verify InfluxDB is also available.
root#db1:~# cd /usr/bin
root#db1:/usr/bin# ./influx

But if I try restart
docker container restart influxdb
I get
Error response from daemon: Cannot restart container influxdb: driver failed programming external connectivity on endpoint influxdb (06ee4d738dffecd1a202840699a899286f4bbb88392e4eb227d65670108687a6): Error starting userland proxy: listen tcp 0.0.0.0:8086: bind: address already in use

How to restart docker container?
If I go for
docker kill influxdb
Error response from daemon: Cannot kill container: influxdb: Container f15a180315d38c2f5fac929b2d0b9be3e8ca2a09033648b5c5174c15a64c4d71 is not running
Problem
As indicated by the error message:
Error response from daemon: Cannot restart container influxdb: driver failed programming external connectivity on endpoint influxdb (06ee4d738dffecd1a202840699a899286f4bbb88392e4eb227d65670108687a6): Error starting userland proxy: listen tcp 0.0.0.0:8086: bind: address already in use
The port 8086 was already blocked ( therefore the address already in use part) by another process. Therefore the container was not able to run, because the container tried to start influxdb, but failed because of the already bound port.
Additionally the output of netstat provided the hint, which process occupies the port:
netstat -nl -p tcp | grep 8086
tcp6 0 0 :::8086 :::* LISTEN 1985/influxd
(see the last part: 1985/influxd)
Solution
Kill the other process (first check, if the process is busy and you should save data before stopping it), e.g. using the kill command:
kill 1985
My docker container is able to successfully build but when I enter the command docker-compose build, the following error is returned:

I don't believe I have another container running so I'm confused by the message Bind for 0.0.0.0:5432 failed: port is already allocated
Is it possible that you ran the same docker-compose earlier, which probably failed or at least failed to clean up the services?
Try running docker ps -a to check if any stopped containers exist. It is possible that the stopped containers are hogging the port. If so, just clear them out using docker rm $(docker ps -qa)
