本文提供了在Red Hat Enterprise Linux (RHEL)系统中安装SQL Server vNext CTP 1.3的完整攻略。

注意

你需要至少3.25GB的内存来运行SQL Server的Linux版。 SQL Server引擎此次测试了最高1 TB内存。

安装 SQL Server

To install the mssql-server package on RHEL, follow these steps:

1. Enter superuser mode.

   sudo su

2. Download the Microsoft SQL Server Red Hat repository configuration file:

   curl https://packages.microsoft.com/config/rhel/7/mssql-server.repo > /etc/yum.repos.d/mssql-server.repo

3. Exit superuser mode.

   exit

4. Run the following commands to install SQL Server:

   sudo yum install -y mssql-server

5. 安装完毕后，运行mssql-conf setup命令，按照出现的提示操作。请务必为超级管理员账户（SA）指定一个强密码（至少8位字符，包含大写和小写字母，数字和/或符号）。

   sudo /opt/mssql/bin/mssql-conf setup

6. 当配置完成后，请确认服务已经运行：

   systemctl status mssql-server

7. 如果允许远程连接，要在RHEL（CentOS）的防火墙开启SQL Server的端口。默认为1433。如果你的防火墙使用FirewallD。则可以使用以下命令：

8. sudo firewall-cmd --zone=public --add-port=1433/tcp --permanentsudo firewall-cmd --reload

更新SQL Server

To upgrade the mssql-server package on RHEL, execute the following command:

   sudo yum update mssql-server

These commands will download the newest package and replace the binaries located under /opt/mssql/. The user generated databases and system databases will not be affected by this operation.

卸载SQL Server

To remove the mssql-server package on RHEL, follow these steps:

1. Run the remove command. This will delete the package and remove the files under /opt/mssql/. However, this command will not affect user-generated and system database files, which are located under /var/opt/mssql.

   sudo yum remove mssql-server

2. Removing the package will not delete the generated database files. If you want to delete the database files use the following command:

   sudo rm -rf /var/opt/mssql/
