[!INCLUDE SQL Server - Linux]
In this tutorial, configure SQL Server snapshot replication on Linux with two instances of SQL Server using Transact-SQL (T-SQL). The publisher and distributor will be the same instance, and the subscriber will be on a separate instance.
[!div class="checklist"]
- Enable SQL Server replication agents on Linux
- Create a sample database
- Configure snapshot folder for SQL Server agents access
- Configure the distributor
- Configure the publisher
- Configure publication and articles
- Configure subscriber
- Run the replication jobs
All replication configurations can be configured with replication stored procedures.
To complete this tutorial, you'll need:
-
Two instances of SQL Server with the latest version of SQL Server on Linux
-
A tool to issue T-SQL queries to set up replication such as SQLCMD or SSMS
See Use SQL Server Management Studio on Windows to manage SQL Server on Linux.
[!NOTE]
[!INCLUDE SQL Server 2017] (CU18) and later support SQL Server Replication for instances of SQL Server on Linux.
-
Enable SQL Server replication agents on Linux. On both host machines, run the following commands in the terminal.
sudo /opt/mssql/bin/mssql-conf set sqlagent.enabled true sudo systemctl restart mssql-server
-
Create the sample database and table. On the publisher create a sample database and table that will act as the articles for a publication.
CREATE DATABASE Sales; GO USE [Sales]; GO CREATE TABLE Customer ( [CustomerID] [int] NOT NULL, [SalesAmount] [decimal] NOT NULL ); GO INSERT INTO Customer (CustomerID, SalesAmount) VALUES (1, 100), (2, 200), (3, 300); GO
On the other SQL Server instance, the subscriber, create the database to receive the articles.
CREATE DATABASE Sales; GO
-
Create the snapshot folder for SQL Server Agents to read/write to on the distributor, create the snapshot folder and grant access to 'mssql' user
sudo mkdir /var/opt/mssql/data/ReplData/ sudo chown mssql /var/opt/mssql/data/ReplData/ sudo chgrp mssql /var/opt/mssql/data/ReplData/
-
Configure distributor. In this example, the publisher will also be the distributor. Run the following commands on the publisher to configure the instance for distribution as well.
DECLARE @distributor AS SYSNAME; DECLARE @distributorlogin AS SYSNAME; DECLARE @distributorpassword AS SYSNAME; -- Specify the distributor name. Use 'hostname' command on in terminal to find the hostname SET @distributor = N'<distributor instance name>'; --in this example, it will be the name of the publisher SET @distributorlogin = N'<distributor login>'; SET @distributorpassword = N'<distributor password>'; -- Specify the distribution database. USE master EXEC sp_adddistributor @distributor = @distributor -- this should be the hostname -- Log into distributor and create Distribution Database. In this example, our publisher and distributor is on the same host EXEC sp_adddistributiondb @database = N'distribution', @log_file_size = 2, @deletebatchsize_xact = 5000, @deletebatchsize_cmd = 2000, @security_mode = 0, @login = @distributorlogin, @password = @distributorpassword; GO DECLARE @snapshotdirectory AS NVARCHAR(500); SET @snapshotdirectory = N'/var/opt/mssql/data/ReplData/'; -- Log into distributor and create Distribution Database. In this example, our publisher and distributor is on the same host USE [distribution]; GO IF (NOT EXISTS (SELECT * FROM sysobjects WHERE name = 'UIProperties' AND type = 'U')) CREATE TABLE UIProperties (id INT); IF (EXISTS (SELECT * FROM::fn_listextendedproperty('SnapshotFolder', 'user', 'dbo', 'table', 'UIProperties', NULL, NULL))) EXEC sp_updateextendedproperty N'SnapshotFolder', @snapshotdirectory, 'user', dbo, 'table', 'UIProperties'; ELSE EXEC sp_addextendedproperty N'SnapshotFolder', @snapshotdirectory, 'user', dbo, 'table', 'UIProperties'; GO
-
Configure publisher. Run the following T-SQL commands on the publisher.
DECLARE @publisher AS SYSNAME; DECLARE @distributorlogin AS SYSNAME; DECLARE @distributorpassword AS SYSNAME; -- Specify the distributor name. Use 'hostname' command on in terminal to find the hostname SET @publisher = N'<instance name>'; SET @distributorlogin = N'<distributor login>'; SET @distributorpassword = N'<distributor password>'; -- Specify the distribution database. -- Adding the distribution publishers EXEC sp_adddistpublisher @publisher = @publisher, @distribution_db = N'distribution', @security_mode = 0, @login = @distributorlogin, @password = @distributorpassword, @working_directory = N'/var/opt/mssql/data/ReplData', @trusted = N'false', @thirdparty_flag = 0, @publisher_type = N'MSSQLSERVER'; GO
-
Configure publication job. Run the following T-SQL commands on the publisher.
DECLARE @replicationdb AS SYSNAME; DECLARE @publisherlogin AS SYSNAME; DECLARE @publisherpassword AS SYSNAME; SET @replicationdb = N'Sales'; SET @publisherlogin = N'<Publisher login>'; SET @publisherpassword = N'<Publisher Password>'; USE [Sales]; GO EXEC sp_replicationdboption @dbname = N'Sales', @optname = N'publish', @value = N'true'; -- Add the snapshot publication EXEC sp_addpublication @publication = N'SnapshotRepl', @description = N'Snapshot publication of database ''Sales'' from Publisher ''<PUBLISHER HOSTNAME>''.', @retention = 0, @allow_push = N'true', @repl_freq = N'snapshot', @status = N'active', @independent_agent = N'true'; EXEC sp_addpublication_snapshot @publication = N'SnapshotRepl', @frequency_type = 1, @frequency_interval = 1, @frequency_relative_interval = 1, @frequency_recurrence_factor = 0, @frequency_subday = 8, @frequency_subday_interval = 1, @active_start_time_of_day = 0, @active_end_time_of_day = 235959, @active_start_date = 0, @active_end_date = 0, @publisher_security_mode = 0, @publisher_login = @publisherlogin, @publisher_password = @publisherpassword;
-
Create articles from the Sales table.
Run the following T-SQL commands on the publisher.
USE [Sales]; GO EXEC sp_addarticle @publication = N'SnapshotRepl', @article = N'customer', @source_owner = N'dbo', @source_object = N'customer', @type = N'logbased', @description = NULL, @creation_script = NULL, @pre_creation_cmd = N'drop', @schema_option = 0x000000000803509D, @identityrangemanagementoption = N'manual', @destination_table = N'customer', @destination_owner = N'dbo', @vertical_partition = N'false';
-
Configure Subscription. Run the following T-SQL commands on the publisher.
DECLARE @subscriber AS SYSNAME; DECLARE @subscriber_db AS SYSNAME; DECLARE @subscriberLogin AS SYSNAME; DECLARE @subscriberPassword AS SYSNAME; SET @subscriber = N'<Instance Name>'; -- for example, MSSQLSERVER SET @subscriber_db = N'Sales'; SET @subscriberLogin = N'<Subscriber Login>'; SET @subscriberPassword = N'<Subscriber Password>'; USE [Sales]; GO EXEC sp_addsubscription @publication = N'SnapshotRepl', @subscriber = @subscriber, @destination_db = @subscriber_db, @subscription_type = N'Push', @sync_type = N'automatic', @article = N'all', @update_mode = N'read only', @subscriber_type = 0; EXEC sp_addpushsubscription_agent @publication = N'SnapshotRepl', @subscriber = @subscriber, @subscriber_db = @subscriber_db, @subscriber_security_mode = 0, @subscriber_login = @subscriberLogin, @subscriber_password = @subscriberPassword, @frequency_type = 1, @frequency_interval = 0, @frequency_relative_interval = 0, @frequency_recurrence_factor = 0, @frequency_subday = 0, @frequency_subday_interval = 0, @active_start_time_of_day = 0, @active_end_time_of_day = 0, @active_start_date = 0, @active_end_date = 19950101; GO
-
Run replication agent jobs. Run the following query to get a list of jobs:
SELECT name, date_modified FROM msdb.dbo.sysjobs ORDER BY date_modified DESC;
Run the Snapshot replication job to generate the snapshot:
USE msdb; GO --generate snapshot of publications, for example EXEC dbo.sp_start_job N'PUBLISHER-PUBLICATION-SnapshotRepl-1'; GO
Run the snapshot replication job to generate the snapshot:
USE msdb; GO --distribute the publication to subscriber, for example EXEC dbo.sp_start_job N'DISTRIBUTOR-PUBLICATION-SnapshotRepl-SUBSCRIBER'; GO
-
Connect subscriber and query replicated data.
On the subscriber, check that the replication is working by running the following query:
SELECT * from [Sales].[dbo].[Customer];
