![]() Datacenter/Zone, Security Group, etc.) that are required in order to launch a server into the chosen cloud. Select the appropriate cloud-specific resources (e.g.Do not include master or slave in the name, because a database server's role can change in the future. Server Name - Provide a nickname for your new database server (e.g., mysql-db1).Next, the Add Server Assistant wizard will walk you through the remaining steps that are required to create a server based on the selected cloud.Select the cloud and the deployment for the new server and click Continue.From the imported ServerTemplate's show page, click the Add Server button.Database Manager for MySQL (RightLink 10).Go to the MultiCloud Marketplace (Design > MultiCloud Marketplace > ServerTemplates) and import the most recently published revision of the following ServerTemplate into the RightScale account.The sample is a bzip2 compressed file (.bz2) file.įollow these steps to add a database server to the deployment. If you are setting up a database server for testing purposes or if you do not have your own dump file, you can use the following sample MySQL dump file to complete the tutorial. It is strongly recommended that Credentials are used to store and use these keys. You will need to provide your “API key” in the “DNS User Key” input and the “Secret key” in the “DNS Secret Key” input. ‘A’ records are created or updated if they already exist. The current version of the ServerTemplate has default support for DNSMadeEasy. It's strongly recommended that you use a TTL of 60 seconds for the DNS record that points to the master database server. For example, the DNS record that points to the master database server should have a low TTL to ensure that the application servers will connect to the correct server within a reasonable amount of time. When you create the DNS records, it's important to set appropriate TTLs to ensure that servers will not stay connected to an old IP address that is no longer assigned to a functional server. the ability to dynamically update the IP address of an A record) for the Master-DB server (at a minimum). Since the IP address of an instance in the cloud is often dynamically assigned at launch time, you are required to use a DNS provider that supports dynamic DNS (i.e. ), which resolves to the Master-DB's IP address. In this type of architecture, the application servers locate the master database server by using Master-DB's FQDN (e.g. The diagram below shows a typical example of a 3-tier website architecture. In a typical 3-tier architecture setup, DNS A records are used to create fully qualified domain names (FQDNs) that map to a particular server or tier of servers. It is strongly recommended that you use volumes to store the contents of the MySQL database for greater efficiency and optimal performance. Backups will be done using the volume snapshots feature of the cloud being used. Volumesĭatabase data will be stored on volumes. Before starting the tutorial it is strongly recommended that you read the Technical Overview of the ServerTemplate which describes its overall functionality. This tutorial describes the steps for launching MySQL database servers running in an asynchronously replicated (master/slave) configuration in the cloud. You must upload the rs-mysql cookbook to your Chef Server.You must have a Chef Server or use Hosted Chef to use this ServerTemplate.This tutorial installs a blank MySQL database and uses a mysql dump file stored in a Github repository to restore a single database.To learn how to create credentials see Create Credentials for Common Inputs. We strongly recommend that you set up credentials for password values and any other sensitive data used for script/recipe inputs.For Amazon EC2, and other clouds that support security groups, you must have a security group defined with TCP port 22 open for SSH access, and any other ports required by the server (for example, the default MySQL port, TCP port 3306), for the required security groups and IP addresses.You must log in under a RightScale account with 'actor,' 'designer', 'security manager,' and 'library' user roles in order to complete the tutorial.To set up two MySQL 5.1/5.5 database servers running in an asynchronously replicated (master/slave) configuration in a single deployment in a public or private cloud environment with data stored on a logical volume made up of two volumes set to backup on the slave every hour.
