Mssql 登录失败 ECONNREFUSED 127.0.0.1:1433

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 .

1. 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.

2. 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

就我而言，我只需要启动容器。

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

我通过将端口从 1422 更新到 1433 来解决此问题，我使用 Kitematic 来实现此更新。

Answer 9

我有同样的情况，这是一个 RAM 问题，但是...... 4GB 对我没有帮助，出于某种原因，在我的情况下，我需要 6，然后它起作用了。

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.
