To back up and restore MySQL data on an Alibaba application, verify that your environment has the required software and a firewall.
Packages that are required on access nodes:
Virtual Server Agent
Access nodes that you run backup and restore operations on must have one of the following operating systems:
Red Hat Enterprise Linux 8.x, 7.x
CentOS 8.x, 7.x
Windows 2019, 2016, 2012
Note: If you have network configuration enabled on the access nodes, before you deploy the Linux proxy, configure a firewall on the cloud proxy and on-premises. For more information, see Configuring a Firewall to Install the Virtual Server Agent on a Cloud VM or Instance.
Supported MySQL Versions
Note: To back up and restore data using MySQL version 8 on Windows, install Microsoft Visual C++ libraries.
User Account Requirements
The MySQL user account must have the following minimum permissions to perform cloud based backup and restore operations using dump-based solutions:
CREATE USER 'new_master_user'@'%' IDENTIFIED BY 'StrongPassword!';
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER ON *.* TO 'new_master_user'@'%' WITH GRANT OPTION;
Alibaba User Permissions
Download the alicloud_min_permission_policy.json file and use it on the Alibaba command line to apply all of the required permissions for backups and restores.
SSL and TLS Support
SSL is supported for MySQL version 5.7 and later. The supported TLS versions to create Alibaba SSL encrypted MySQL instances are TLS 1.0, 1.1 and 1.2.
