SQL Server實(shí)例間同步登錄用戶
問題痛點(diǎn)：由于AlwaysOn和數(shù)據(jù)庫鏡像無法同步數(shù)據(jù)庫外實(shí)例對象，例如 登錄用戶、作業(yè)、鏈接服務(wù)器等，導(dǎo)致主庫切換之后，應(yīng)用連接不上數(shù)據(jù)庫或者作業(yè)不存在導(dǎo)致每晚跑批任務(wù)漏跑等
目前來看，作業(yè)等其他實(shí)例對象的同步還比較難實(shí)現(xiàn)，比如作業(yè)分為很多步驟，而且作業(yè)包含的命令也比較復(fù)雜，作業(yè)也支持調(diào)用其他子系統(tǒng)，比如 PowerShell ，ActiveX，CmdExec等數(shù)據(jù)庫外部程序和命令，用動(dòng)態(tài)SQL方式很難處理
目前只有升級到SQL Server 2022并使用包含可用性組（支持同步登錄用戶、SQL代理作業(yè)、鏈接服務(wù)器）才能最絲滑的解決這個(gè)問題
本文主要介紹的是登錄用戶的同步，畢竟登錄用戶的重要性還是比較高的，應(yīng)用需要先通過登錄用戶登錄DB實(shí)例才能執(zhí)行后續(xù)的操作
?文章來源：http://www.zghlxwxcb.cn/news/detail-706339.html
要在SQLServer實(shí)例間同步登錄用戶，主要有幾種方法
1、創(chuàng)建操作系統(tǒng)域用戶，然后創(chuàng)建基于這個(gè)域用戶的登錄用戶，因?yàn)橛蛴脩粼谟蚶锩媸峭降?，但是這種方法前提是需要有域環(huán)境，而且普通開發(fā)人員一般也沒有域控機(jī)器權(quán)限創(chuàng)建域用戶
2、使用外部第三方工具，比如 sqlcmd，PowerShell，SQLServer自帶的SSIS服務(wù)
3、使用鏈接服務(wù)器 和 動(dòng)態(tài)拼接SQL方法
?
本文主要使用第三種方法，因?yàn)榈谌N方法本人認(rèn)為有下面幾種優(yōu)勢
1、保證最低維護(hù)成本，純SQL實(shí)現(xiàn)，不需要借助第三方工具
2、通用性，幾乎所有SQL Server版本都能用，也不需要像第三方工具例如 PowerShell那樣有時(shí)候需要升級版本
3、兼容性，跨操作系統(tǒng)平臺Linux、Windows
4、高可靠性，使用SQLServer自帶原生工具，足夠簡單高效

這個(gè)工具腳本的主要流程如下

具體使用步驟
假設(shè)有三個(gè)AlwaysOn節(jié)點(diǎn)，分別是

step1： 創(chuàng)建鏈接服務(wù)器，在所有AlwaysOn節(jié)點(diǎn)上創(chuàng)建其他節(jié)點(diǎn)的鏈接服務(wù)器，比如在192.168.10.10上創(chuàng)建其他節(jié)點(diǎn)鏈接服務(wù)器，下面腳本在192.168.10.10服務(wù)器上執(zhí)行，其他節(jié)點(diǎn)以此類推

對于這個(gè)自動(dòng)定時(shí)同步登錄用戶腳本有以下說明
本工具腳本遵循的思想是，不做減法，只做加法，盡可能減少對線上生產(chǎn)環(huán)境影響，主要有下面幾點(diǎn)：
（1）新增用戶：如果從庫不存在同步過來的用戶，就新建用戶
（2）更新用戶：如果從庫存在同步過來的用戶，就會判斷用戶SID和用戶密碼是否一樣，如果用戶SID一樣，密碼不一樣，就更新用戶密碼
（3）刪除用戶：如果從庫存在同名用戶，就不新建用戶，否則新建用戶，為了盡可能減少對線上生產(chǎn)環(huán)境影響，不做刪除用戶操作，所以如果從庫存在同名用戶并且用戶SID不同，建議手動(dòng)刪除用戶由腳本自動(dòng)同步主庫用戶過來
?無論是新增用戶還是更新用戶，都會執(zhí)行添加服務(wù)器角色權(quán)限的步驟，如果同名用戶已經(jīng)存在當(dāng)前服務(wù)器角色權(quán)限，那么再次執(zhí)行添加服務(wù)器角色權(quán)限并不會有任何影響，而且本工具腳本并不會刪除同名用戶的服務(wù)器角色權(quán)限
最終目的：不做減法，只做加法，盡可能減少對線上生產(chǎn)環(huán)境影響

對于這個(gè)自動(dòng)定時(shí)同步登錄用戶腳本有下面幾個(gè)注意點(diǎn)
1、本工具腳本使用sa用戶來創(chuàng)建鏈接服務(wù)器，所以不會同步sa用戶，注意如果更改了sa用戶密碼，也要同步更改鏈接服務(wù)器密碼，當(dāng)然您也可以使用其他有足夠權(quán)限的用戶來創(chuàng)建鏈接服務(wù)器
2、新建登錄用戶的時(shí)候，一定要確保在主庫上新建登錄用戶，否則可能會無法實(shí)施數(shù)據(jù)庫角色權(quán)限或者無法同步該登錄用戶
3、新建登錄用戶時(shí)候，登錄用戶名不要帶有特殊字符，例如單引號，否則差異腳本有可能不work
4、這個(gè)腳本是針對AlwaysOn集群，當(dāng)然如果你是數(shù)據(jù)庫鏡像環(huán)境，你可以改一下代碼，把判斷AlwaysOn主庫的部分改為判斷鏡像主庫就可以了
5、如果對登錄用戶同步延遲有要求，那么可以修改作業(yè)執(zhí)行頻率，默認(rèn)是60分鐘執(zhí)行一次
