Linux下安装SQL Server 2016（连接篇SQL Server on linux）

连接数据库

（1）设置防火墙

要连接数据库，首先要打开防火墙上1433端口，也就是,增加tcp端口1433到公共区域，并且永久生效。

[root@localhost Desktop]# firewall-cmd --zone=public --add-port=1433/tcp --permanent

success

[root@localhost Desktop]# firewall-cmd --reload

success

（2）下载客户端工具的源、安装客户端工具

可以参考这个文章：安装sql server的客户端工具

也是非常简单的，先下载，然后安装

。

（3）连接sql sever
这里用sqlcmd来连接sql server，下面是一些命令行参数。

[plain] view plain copy







[root@localhost Desktop]# sqlcmd

Microsoft (R) SQL Server Command Line Tool

Version 14.0.0001.246 Linux

Copyright (c) 2012 Microsoft. All rights reserved.

usage: sqlcmd [-U login id] [-P password]

[-S server or Dsn if -D is provided]

[-H hostname] [-E trusted connection]

[-N Encrypt Connection][-C Trust Server Certificate]

[-d use database name] [-l login timeout] [-t query timeout]

[-h headers] [-s colseparator] [-w screen width]

[-a packetsize] [-e echo input] [-I Enable Quoted Identifiers]

[-c cmdend]

[-q "cmdline query"] [-Q "cmdline query" and exit]

[-m errorlevel] [-V severitylevel] [-W remove trailing spaces]

[-u unicode output] [-r[0|1] msgs to stderr]

[-i inputfile] [-o outputfile]

[-k[1|2] remove[replace] control characters]

[-y variable length type display width]

[-Y fixed length type display width]

[-p[1] print statistics[colon format]]

[-R use client regional setting]

[-K application intent]

[-M multisubnet failover]

[-b On error batch abort]

[-D Dsn flag, indicate -S is Dsn]

[-X[1] disable commands, startup script, environment variables [and exit]]

[-x disable variable substitution]

[-? show syntax summary]

这里的-S是指定服务器名称，-U指定用户名，回车后会提示输入密码。
接下来查询当前是哪个库、创建了一个叫test的库、创建了一个叫tb的表、查询tb表的记录数。

[plain] view plain copy







[root@localhost Desktop]# sqlcmd -S localhost -U sa

Password:

1> select db_name();

2> go

--------------------------------------------------------------------------------------------------------------------------------

master

(1 rows affected)

1> create database test;

2> go

1> use test;

2> go

Changed database context to 'test'.

1> select * into tb from sys.tables;

2> go

(1 rows affected)

1> select count(*) from tb;

2> go

-----------

1

(1 rows affected)

1>

（4）在windows上用Microsoft SQL Server Management Studio（ssms）连接

连接上sql server，查询表tb的数据。



另外，可以在Linux中查询当前连接到sql server的会话，发现有sqlcmd命令，还有ssms，在看看hostprocess进程号就是3228.
