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 developerMSSQL_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='

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 developerMSSQL_PID='evaluation'

可以改为以下7种选项

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"' >> ~/.bashrcsource ~/.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
