SQL Server实例间同步登录用户

SQL Server实例间同步登录用户

问题痛点：由于AlwaysOn和数据库镜像无法同步数据库外实例对象，例如 登录用户、作业、链接服务器等，导致主库切换之后，应用连接不上数据库或者作业不存在导致每晚跑批任务漏跑等

目前来看，作业等其他实例对象的同步还比较难实现，比如作业分为很多步骤，而且作业包含的命令也比较复杂，作业也支持调用其他子系统，比如 PowerShell ，ActiveX，CmdExec等数据库外部程序和命令，用动态SQL方式很难处理

目前只有升级到SQL Server 2022并使用包含可用性组（支持同步登录用户、SQL代理作业、链接服务器）才能最丝滑的解决这个问题

本文主要介绍的是登录用户的同步，毕竟登录用户的重要性还是比较高的，应用需要先通过登录用户登录DB实例才能执行后续的操作

 

要在SQLServer实例间同步登录用户，主要有几种方法

1、创建操作系统域用户，然后创建基于这个域用户的登录用户，因为域用户在域里面是同步的，但是这种方法前提是需要有域环境，而且普通开发人员一般也没有域控机器权限创建域用户

2、使用外部第三方工具，比如 sqlcmd，PowerShell，SQLServer自带的SSIS服务

3、使用链接服务器 和 动态拼接SQL方法

 

本文主要使用第三种方法，因为第三种方法本人认为有下面几种优势

1、保证最低维护成本，纯SQL实现，不需要借助第三方工具

2、通用性，几乎所有SQL Server版本都能用，也不需要像第三方工具例如 PowerShell那样有时候需要升级版本

3、兼容性，跨操作系统平台Linux、Windows

4、高可靠性，使用SQLServer自带原生工具，足够简单高效

 

 

这个工具脚本的主要流程如下

 

 

具体使用步骤

假设有三个AlwaysOn节点，分别是

node1 ip：192.168.10.10

node2 ip：192.168.10.11

node3 ip：192.168.10.12

step1： 创建链接服务器，在所有AlwaysOn节点上创建其他节点的链接服务器，比如在192.168.10.10上创建其他节点链接服务器，下面脚本在192.168.10.10服务器上执行，其他节点以此类推

EXEC master.dbo.sp_addlinkedsrvlogin 
@rmtsrvname = @IP,

step2： 创建存储过程，在所有AlwaysOn节点上创建存储过程，记住是所有AlwaysOn节点都要执行

对于这个自动定时同步登录用户脚本有以下说明

本工具脚本遵循的思想是，不做减法，只做加法，尽可能减少对线上生产环境影响，主要有下面几点：

（1）新增用户：如果从库不存在同步过来的用户，就新建用户

（2）更新用户：如果从库存在同步过来的用户，就会判断用户SID和用户密码是否一样，如果用户SID一样，密码不一样，就更新用户密码

（3）删除用户：如果从库存在同名用户，就不新建用户，否则新建用户，为了尽可能减少对线上生产环境影响，不做删除用户操作，所以如果从库存在同名用户并且用户SID不同，建议手动删除用户由脚本自动同步主库用户过来

 无论是新增用户还是更新用户，都会执行添加服务器角色权限的步骤，如果同名用户已经存在当前服务器角色权限，那么再次执行添加服务器角色权限并不会有任何影响，而且本工具脚本并不会删除同名用户的服务器角色权限

最终目的：不做减法，只做加法，尽可能减少对线上生产环境影响

 

 

对于这个自动定时同步登录用户脚本有下面几个注意点

1、本工具脚本使用sa用户来创建链接服务器，所以不会同步sa用户，注意如果更改了sa用户密码，也要同步更改链接服务器密码，当然您也可以使用其他有足够权限的用户来创建链接服务器

2、新建登录用户的时候，一定要确保在主库上新建登录用户，否则可能会无法实施数据库角色权限或者无法同步该登录用户

3、新建登录用户时候，登录用户名不要带有特殊字符，例如单引号，否则差异脚本有可能不work

4、这个脚本是针对AlwaysOn集群，当然如果你是数据库镜像环境，你可以改一下代码，把判断AlwaysOn主库的部分改为判断镜像主库就可以了

5、如果对登录用户同步延迟有要求，那么可以修改作业执行频率，默认是60分钟执行一次
