Sample: Unattended SQL Server installation script for SUSE Linux Enterprise Server

Artikkeli
07/15/2024

Applies to: SQL Server - Linux

This sample bash script installs SQL Server on SUSE Linux Enterprise Server (SLES) without interactive input. It provides examples of installing the Database Engine, the SQL Server command-line tools, SQL Server Agent, and performs post-install steps. You can optionally install full-text search and create an administrative user.

Tip

If you don't need an unattended installation script, the fastest way to install SQL Server is to follow the quickstart for SLES. For other setup information, see Installation guidance for SQL Server on Linux.

Prerequisites

You need at least 2 GB of memory to run SQL Server on Linux.
The file system must be XFS or EXT4. Other file systems, such as BTRFS, are unsupported.
For other system requirements, see System requirements for SQL Server on Linux.

Important

SQL Server requires libsss_nss_idmap0, which isn't provided by the default SLES repositories. You can install it from the SLES SDK.

Sample script

This example installs SQL Server 2019 (15.x) on SLES v15 SP3. If you want to install a different version of SQL Server or SLES, change the Microsoft repository paths accordingly.

Save the sample script to a file and then to customize it. You must replace the variable values in the script. You can also set any of the scripting variables as environment variables, as long as you remove them from the script file.

Important

The SA_PASSWORD environment variable is deprecated. Use MSSQL_SA_PASSWORD instead.

#!/bin/bash -e

# Use the following variables to control your install:

# Password for the SA user (required)
MSSQL_SA_PASSWORD='<YourStrong!Passw0rd>'

# Product ID of the version of SQL Server you're installing
# Must be evaluation, developer, express, web, standard, enterprise, or your 25 digit product key
# Defaults to developer
MSSQL_PID='evaluation'

# Enable SQL Server Agent (recommended)
SQL_ENABLE_AGENT='y'

# Install SQL Server Full Text Search (optional)
# SQL_INSTALL_FULLTEXT='y'

# Create an additional user with sysadmin privileges (optional)
# SQL_INSTALL_USER='<Username>'
# SQL_INSTALL_USER_PASSWORD='<YourStrong!Passw0rd>'

if [ -z $MSSQL_SA_PASSWORD ]
then
  echo Environment variable MSSQL_SA_PASSWORD must be set for unattended install
  exit 1
fi

fi

echo Done!

Run the script

To run the script:

Paste the sample into your favorite text editor and save it with a memorable name, like install_sql.sh.
Customize MSSQL_SA_PASSWORD, MSSQL_PID, and any of the other variables you'd like to change.
Mark the script as executable
```
chmod +x install_sql.sh
```
Run the script
```
./install_sql.sh
```

Understand the script

The first thing the bash script does is set a few variables. These variables can be either scripting variables, like the sample, or environment variables. The variable MSSQL_SA_PASSWORD is required by SQL Server installation. The others are custom variables created for the script. The sample script performs the following steps:

Import the public Microsoft GPG keys.
Register the Microsoft repositories for SQL Server and the command-line tools.
Update the local repositories.
Install SQL Server.
Configure SQL Server with the MSSQL_SA_PASSWORD and automatically accept the End-User License Agreement.
Automatically accept the End-User License Agreement for the SQL Server command-line tools, install them, and install the unixODBC-devel package.
Add the SQL Server command-line tools to the path for ease of use.
Enable the SQL Server Agent if the scripting variable SQL_ENABLE_AGENT is set, on by default.
Optionally install SQL Server Full-Text search, if the variable SQL_INSTALL_FULLTEXT is set.
Unblock port 1433 for TCP on the system firewall, necessary to connect to SQL Server from another system.
Optionally set trace flags for deadlock tracing (requires uncommenting the lines).
SQL Server is now installed, to make it operational, restart the process.
Verify that SQL Server is installed correctly, while hiding any error messages.
Create a new server administrator user if SQL_INSTALL_USER and SQL_INSTALL_USER_PASSWORD are both set.

Unattended install

Simplify multiple unattended installs and create a stand-alone bash script that sets the proper environment variables. You can remove any of the variables the sample script uses and put them in their own bash script.

#!/bin/bash
export MSSQL_SA_PASSWORD='<YourStrong!Passw0rd>'
export MSSQL_PID='evaluation'
export SQL_ENABLE_AGENT='y'
export SQL_INSTALL_USER='<Username>'
export SQL_INSTALL_USER_PASSWORD='<YourStrong!Passw0rd>'

Then run the bash script as follows:

. ./my_script_name.sh
