第一部分：SQL Server的安装及配置
1.1，下载Microsoft SQL Server Red Hat软件仓库配置文件，此仓库为我们提供了安装SQL Server所必须的软件
$ curl -o /etc/yum.repos.d/mssql-server.repo https://packages.microsoft.com/config/rhel/7/mssql-server.repo
1.2，更新软件仓库并安装SQL Server
$ yum update
$ yum -y install mssql-server
1.3，运行包安装完成后，使用mssql-conf安装并按照提示操作以设置SA密码，并选择你的版本(注意，设置密码时请符合密码安全策略，建议最少8个字符，包括大写和小写字母，十进制数字和/或非字母数字符号。
$ /opt/mssql/bin/mssql-conf setup

Setup has completed successfully. SQL Server is now starting.
1.4，配置完成后，请验证服务是否正在运行。
$ systemctl status mssql-server
● mssql-server.service – Microsoft SQL Server Database Engine
Loaded: loaded (/usr/lib/systemd/system/mssql-server.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2017-10-12 03:50:58 CST; 3min 58s ago
Docs: https://docs.microsoft.com/en-us/sql/linux Main PID: 3238 (sqlservr)
CGroup: /system.slice/mssql-server.service
├─3238 /opt/mssql/bin/sqlservr
└─3258 /opt/mssql/bin/sqlservr
1.5，如果你的服务器允许远程连接数据库，请在防火墙上设置相关策略，SQL Server默认使用1433 / tcp端口
$ firewall-cmd –permanent –add-port = 1433 / tcp
$ firewall-cmd –reload
第二部分：SQL Server的其他配置此时
数据库已经准备就绪。如果需要安装SQL Server命令行，例如创建数据库，需要使用命令sqlcmd和bcp。则需要安装相应软件，此时请执行以下操作：
2.1，同样下载Microsoft Red Hat软件库配置文件，并更新
$ yum update
2.2，如果你有以前版本的mssql工具安装，请删除任何较旧的unixODBC程序包。如果没有，请跳过此步骤，直接进行2.3步
$ yum remove unixODBC-utf16 unixODBC-utf16-devel
2.3，安装mssql工具与unixODBC开发人员包
$ yum install -y mssql-tools unixODBC-devel
Loaded plugins: product-id, search-disabled-repos, subscription-manager

2.4，为方便起见，添加/opt/mssql-tools/bin/到你路径环境变量。这使您可以在Bash中直接运行工具，而无需指定完整路径。运行以下命令以修改路径登录会话和交互式/非 – 登录会话：
$ echo ‘export PATH=”$PATH:/opt/mssql-tools/bin”‘ >> /etc/bashrc
$ echo ‘export PATH=”$PATH:/opt/mssql-tools/bin”‘ >> /etc/profile
$ source /etc/bashrc
注意：这里做了全局的环境变量，如果您不要设置全局的环境变量，可以将/etc/bashrc替换为$HOME/.bashrc，将/etc/profile替换为$HOME/.bash_profile
第三部分：SQL服务器本地测试
3.1，测试，使用本地方式登录数据库，如果登录成功，则提示1>
$ /opt/mssql-tools/bin/sqlcmd -S 127.0.0.1 -U sa
Password:
1> CREATE DATABASE test
2> GO
1> USE test 2> GO
Changed database context to ‘test’.
1> quit
