SQL Server 2017在Linux平台安装虽然很简单，只要按照指令一行一行贴上就可以完成，但懒人总是想着更快的方法，于是找了官方文件发现竟然有自动安装的范例，测试一下果真OK。

请参阅以Red Hat Enterprise Linux为例，利用vi指令在Linux内建一个档案例如installsql.sh，然后将范例指令码贴上

预设只会安装database engine，SQL Server 命令列工具，SQL Server Agent

#!/bin/bash

# Use the following variables to control your install:

# Password for the SA user (required)
MSSQL_SA_PASSWORD=''

# 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'

# Install SQL Server Agent (recommended)
SQL_INSTALL_AGENT='y'

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

# Create an additional user with sysadmin privileges (optional)
# SQL_INSTALL_USER=''
# SQL_INSTALL_USER_PASSWORD=''

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

sudo ACCEPT_EULA=Y yum install -y mssql-tools unixODBC-devel

# Add SQL Server tools to the path by default:
echo Adding SQL Server tools to your path...
echo PATH="$PATH:/opt/mssql-tools/bin" >> ~/.bash_profile
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
source ~/.bashrc

# Optional SQL Server Agent installation:
if [ ! -z $SQL_INSTALL_AGENT ]
then
  echo Installing SQL Server Agent...
  sudo yum install -y mssql-server-agent
fi

# Optional SQL Server Full Text Search installation:
if [ ! -z $SQL_INSTALL_FULLTEXT ]
then
    echo Installing SQL Server Full-Text Search...
    sudo yum install -y mssql-server-fts
fi

# Configure firewall to allow TCP port 1433:
echo Configuring firewall to allow traffic on port 1433...

# Restart SQL Server after making configuration changes:
echo Restarting SQL Server...
sudo systemctl restart mssql-server

# Connect to server and get the version:
counter=1
errstatus=1
while [ $counter -le 5 ] && [ $errstatus = 1 ]
do
  echo Waiting for SQL Server to start...
  sleep 5s
  /opt/mssql-tools/bin/sqlcmd \
    -S localhost \
    -U SA \
    -P $MSSQL_SA_PASSWORD \
    -Q "SELECT @@VERSION" 2>/dev/null
  errstatus=$?
  ((counter++))
done

# Display error if connection failed:
if [ $errstatus = 1 ]
then
  echo Cannot connect to SQL Server, installation aborted
  exit $errstatus
fi

# Optional new user creation:

then
  echo Creating user $SQL_INSTALL_USER

fi

echo Done!

要修改的参数只有1个，修改SA的密码

# Password for the SA user (required)
MSSQL_SA_PASSWORD=''

以下为可以调整的选项

安装的版本预设是试用版

# Defaults to developer
MSSQL_PID='evaluation'

可以改为以下7种选项
这里写图片描述

如果要安装全文检索，请移除#

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

如果要建立另一个具有sysadmin权限使用者请移除#后输入使用者名称及密码

# Create an additional user with sysadmin privileges (optional)
# SQL_INSTALL_USER=''
# SQL_INSTALL_USER_PASSWORD=''

如果要开启追踪dead lock请移除#

# Example of setting post-installation configuration options
# Set trace flags 1204 and 1222 for deadlock tracing:
#echo Setting trace flags...
#sudo /opt/mssql/bin/mssql-conf traceflag 1204 1222 on

实测后有段指令少了，要让sqlcmd/bcp bash壳层互动式/非登入工作阶段，少了第2行指令

echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
source ~/.bashrc

存档离开vi后，将档案修改为可执行

chmod +x installsql.sh

然后执行即可

./installsql.sh
