如果使用SSMS客户端的UI界面去修改的话， 那么多服务器一台一台去修改，不仅费时费力，而且枯燥无聊。只能使用脚本，一旦写好一个脚本，而后使用Multiple Server Query Execution（极力推荐使用这个管理、维护数据库），执行一次脚本，全部搞定。剩下的时间你可以喝喝茶、学习下新知识！
DECLARE @EmailAccount sysname;
DECLARE @SmtpServer sysname;
DECLARE @EmailAddress NVARCHAR(120);
DECLARE @EmailSuffix NVARCHAR(32);
DECLARE @NewEamilAddress NVARCHAR(120);
--DECLARE @ActualEmailSuffix NVARCHAR(32)=‘xxxx.com‘; SQL Server 2005不支持此功能，会报Cannot assign a default value to a local variable.
DECLARE @ActualEmailSuffix NVARCHAR(32);
DECLARE @ActualSmtpServer sysname;
SET @ActualEmailSuffix=‘xxx.com‘;
SET @ActualSmtpServer=‘192.168.xxx.xxx‘;
DECLARE EmailAccount_Cursor CURSOR FAST_FORWARD
FOR
SELECT sa.[name]
,ss.[servername]
,sa.email_address
FROM [msdb].[dbo].[sysmail_server] ss
INNER JOIN [msdb].[dbo].[sysmail_account] sa
ON ss.[account_id]=sa.[account_id];
OPEN EmailAccount_Cursor;
FETCH NEXT FROM EmailAccount_Cursor INTO @EmailAccount, @SmtpServer,@EmailAddress;
WHILE @@FETCH_STATUS = 0
BEGIN
IF LTRIM(RTRIM(@SmtpServer))!=@ActualSmtpServer
BEGIN
EXECUTE msdb.dbo.sysmail_update_account_sp
@account_name = @EmailAccount
,@mailserver_name=@ActualSmtpServer;
PRINT @SmtpServer;
PRINT @EmailAccount;
END;
SET @EmailSuffix=SUBSTRING(@EmailAddress,CHARINDEX(‘@‘,@EmailAddress)+1, LEN(@EmailAddress) -CHARINDEX(‘@‘,@EmailAddress))
IF @EmailSuffix!=@ActualEmailSuffix
BEGIN
SET @NewEamilAddress= REPLACE(@EmailAddress,@EmailSuffix,@ActualEmailSuffix);
EXECUTE msdb.dbo.sysmail_update_account_sp
@account_name = @EmailAccount
,@email_address=@NewEamilAddress
,@mailserver_name=@SmtpServer;
PRINT @EmailAccount;
PRINT @NewEamilAddress;
END;
FETCH NEXT FROM EmailAccount_Cursor INTO @EmailAccount, @SmtpServer,@EmailAddress;
END
CLOSE EmailAccount_Cursor;
DEALLOCATE EmailAccount_Cursor;

如果不会用salt或者ansible的话，最简单的方法是找一台发布机器，将这台机器的公钥放在其他服务器中，然后就可以执行脚本了
for i in {ip list};do scp nginx.conf $i:/nginxdir && ssh $i "nginx -s reload";done
确保配置正确，不然报错，可在中间加上nginx -t 验证

使用自动化运维工具salt，怎么使用就自己去折磨一下吧。
