I am very new to SQL and database servers. I have recently been using SQL Server Express and accessing my database using SQL Server Management Studio on Windows. I am now trying to achieve a similar setup on a Linux machine.

I would like to create a local SQL Server instance on the machine, and then use SQLectron as a GUI client for querying my database. I am using Manjaro Linux and so install my packages from the AUR.

So far I have installed mssql-server, mssql-tools and sqlectron-gui. I have run the sudo /opt/mssql/bin/mssql-conf setup command in order to (I believe) set up a local server. After doing so, running the command systemctl status mssql-server returns this:

[kev@XPS-Manjaro ~]$ systemctl status mssql-server

I am now attempting to create a local connection to my server through SQLectron on the following screen:

As I have very little experience with SQL Servers, I am completely lost with where to get all of these credentials to connect to my local server. The only one I know of is the password which I set in the sudo /opt/mssql/bin/mssql-conf setup command.

How do I find the server name, host address (127.0.0.1?), port, domain, Unix socket path and username?

If you are running the GUI on the same machine as the mssql-server service, then you can use localhost for the address (127.0.0.1). If you are running the GUI from a different workstation, you'll need the IPv4 address of the machine where the mssql-server service is running. You can obtain that by running ifconfig from a Linux terminal prompt. Sample output from ifconfig:

eth0: flags=4163  mtu 1500
        ether 00:15:5d:89:45:01  txqueuelen 1000  (Ethernet)
        RX packets 423  bytes 137827 (134.5 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

eth1: flags=4163  mtu 1500
        inet 192.168.200.11  netmask 255.255.255.0  broadcast 192.168.200.255
        inet6 fe80::2f70:9d15:8e7d:16cb  prefixlen 64  scopeid 0x20
        ether 00:15:5d:89:45:04  txqueuelen 1000  (Ethernet)
        RX packets 20138  bytes 2006000 (1.9 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 19756  bytes 30125657 (28.7 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10
        loop  txqueuelen 1  (Local Loopback)
        RX packets 3239  bytes 361340 (352.8 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 3239  bytes 361340 (352.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

In the output above, the bit that is important is the "inet" address, which in my case is 192.168.200.11.

The default port for SQL Server is 1433 - unless you chose a different port in mssql-conf use that port number. Ensure the firewall on the Linux box is allowing outside connections via 1433, if you intend to connect to SQL Server via the network.

Use sa as the login, and the password you specified during SQL Server setup via the sudo /opt/mssql/bin/mssql-conf setup command.

I would leave the domain and unix socket path blank.

Once you have connected to the instance, you may want to configure a non-sa account. Do that with the CREATE LOGIN statement.

Just an FYI, you can use SQL Server Management Studio to connect to SQL Server on Linux, if that's your desire. Alternately, you can download Microsoft's native GUI client for Linux (and Windows & Mac), Azure Data Studio, here.

  • One last follow on: If I now wanted to access my database from within a Python script, would I just need to configure my non-sa account as you mentioned, and then install some driver? I used the ODBC Driver when working on Windows. In my Pyton script on Windows, I got my server name for the connection engine from SSMS which was in the form of CPX-9GL9XXXXXXX\SQLEXPRESS. How can I find this equivalent server name without having access to SSMS?

  • SQL Server Browser is used to locate SQL Server instances without knowing the port number in advance... so for CPX-9GL9XXXXXXX\SQLEXPRESS -> SQLEXPRESS is the instance name, which would be translated by SQL Server Browser service into a port number. Unfortunately, SQL Server Browser is not yet supported on Linux, so you need to know the port number, which is 1433 by default.

  • I'm not certain what driver you'd use, but the mssql-tools package includes an odbc driver as far as I know.
