Mssql login fail ECONNREFUSED 127.0.0.1:1433 - sql-server

Question

while trying to log in using this .. mssql -u sa -p mypassword .i get this error, Error: Failed to connect to localhost:1433 - connect ECONNREFUSED 127.0.0.1:1433
I have installed sql server on docker using this https://www.microsoft.com/en-us/sql-server/developer-get-started/java-mac tutorial and started it.
I am using mac os sierra. I have searched all over internet including stackoverflow for this but gotten no answer. The only answer i get is to enable tcp/ip using sql configuration manager, but mac os doesn't have a configuration manager so I can enable the tcp/ip. Kindly assist.

Answer 1

I finally found the solution .. the docker set the memory as 2GB while the MS SQL server requires 3.25GB... All i had to do was go to the Docker preferences and changed the memory to 4GB and it works :). I was using sql server on docker on Mac.

Answer 2

I'm using docker to set up containers and then sql-cli to access SQL server. This is how I resolved that error which I got after providing mssql -u sa -p mypassword.
What I didn't realize at the beginning was a too simple password provided before with setting up a docker container:
docker run -d --name Homer -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=myPassw0rd' -p 1433:1433 microsoft/mssql-server-linux
The Terminal doesn't say this and only after going to docker > Kitematic and checking the logs of the just created container I saw such a security warning. I deleted that container and created a container with a strong password.
Then I got the error after I've started a wrong container (so the connection failed because I was trying to provide the password for a different container). Since then, I prefer to use Kinematic to manage and access my containers. Before I type mssql -u sa -p mypassword in the Terminal and start to work, I just go to docker > Kinematic and Start my container.

Answer 3

In my case the container exited due to an insecure mssql password.
Try reading the container logs.

Answer 4

In my case, I just needed to start the container.
docker start {container_name}

Answer 5

In my case (I was following this tutorial https://database.guide/how-to-install-sql-server-on-a-mac/) the problem was the host address.
I was trying to connect to localhost and I got the ECONNREFUSED message but then I realized that I needed to use the local IP docker assigned to the container (it was something like 192.168.xxx.xxx), so:
mssql -s 192.168..... -o 1433 -u sa -p 'mypassword'
finally worded.

Answer 6

I had the same, in my case I notice that the problem was the PORT, so:
1)Check if the container is running with
docker start "container_name"
2)Then, get the correct PORT with:
docker ps
3) Run it
mssql -s "PORT" -o 1433 -u sa -p "pwd"

Answer 7

I'm adding this answer to complement Krzysztof Tomasz's answer.
I was following this guide: How to Install SQL Server on a Mac
Everything was going well but at the time of connecting to the container with this command:
mssql -u sa -p mypass1
I got:
Error: Failed to connect to localhost:1433 - connect ECONNREFUSED
127.0.0.1:1433
Then I opened Docker app, clicked the container and in the Logs menu I could see the following:
2020-02-05 16:26:45.71 spid20s ERROR: Unable to set system
administrator password: Password validation failed. The password does
not meet SQL Server password policy requirements because it is too
short. The password must be at least 8 characters..
The password I set had only 7 chars. :o)
Now this makes sense.
This is also documented # Microsoft doc here:
Quickstart: Run SQL Server container images with Docker
Solved this problem by removing the container and launching it again...
As I only had one container I ran the following command:
docker rm $(docker ps -a -q)
Then launched sql server image again with a stronger password:
docker run -d --name sql_server_demo -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=MyPass11' -p 1433:1433 microsoft/mssql-server-linux

Answer 8

I resolved this issue by updating the port from 1422 to 1433, I used Kitematic to implement this update.

Answer 9

I had the same, and it was a RAM issue, HOWEVER... 4GB didn't do it for me, for some reason in my case I needed 6, then it worked.

Answer 10

Make sure you have started the container in docker.
Command to start a container: docker start container "containerName"
and then try to connect mssql

Answer 11

I had same problem too, after study the logs with two commands:
docker ps -a
then
docker logs 99373f58f2ff
I understood that problem is related to the password dose not to meet SQL Server password policy! That's is.
