This section covers the steps necessary to set up SSL. These settings are optional when you initially create a cluster and can be done at a later point in time.
Configure SSL settings
You have the option to implement SSL for the cluster at any point in time. If the SQL Server requires SSL, check the box to enable SSL for the cluster. You will need to provide a server certificate and Server Key to ScaleArc. The SSL certificate must be generated by a CA-Authority that is already approved by the application hosts for it to be accepted.
If the SSL setting is disabled, ScaleArc negotiates down LOGIN encryption for client connections. Unlike SQL server, ScaleArc does not auto-generate self-signed SSL certificate. This happens in authentication offload ON mode only.
Follow these steps:
- Click the Clusters tab > Add Cluster button on the ScaleArc dashboard.
- Locate SSL Settings on the screen. This is the fourth panel on the Create Cluster screen.
- Select the SSL offload checkbox to show the SSL Settings screen.
Then, configure the fields as follows:
Field/Button Description Default/User input SSL Offload SSL offload allows you to establish secure communication between the client and the server via ScaleArc.
Select the checkbox. Server certificate Requires a Server certificate as a prerequisite. The SSL Certificate must be generated by a CA-Authority that is already approved by the application hosts, for it to be accepted by them. All certificates should be in the PEM format. Browse to locate and attach the appropriate Server certificate. Server Key Requires a Server Key as a prerequisite. Key-related files must be in PEM format. Browse to locate and attach the appropriate Server Key. Validate Client Allows ScaleArc to validate the clients connecting to ScaleArc based on their issuer. Select the check box to activate. CA certificate When ScaleArc communicates with the DB Server, it can also establish SSL connections using certificates, if it is required that ScaleArc's SSL communication with the DB server should use client certificates then enable the "Client Certificate" option and upload the Client Certificate and Key.
Browse to locate and attach the appropriate CA certificate. Enable client certificate Select the check box to activate. Client certificate ScaleArc can also connect to the MySQL server using client certificates. If you require secure communication between ScaleArc and the DB server then enable the client certificate option and upload the client certificate and key pair.
Browse to locate and attach the appropriate client certificate. Client Key Browse to locate and attach the client key pair. Validate Server Allows ScaleArc to validate the DB server communication and upload the appropriate CA certificate.
Select the check box to activate. CA certificate Browse to locate and attach the CA certificate. Upload Uploads the attachments. Note that re-uploading or replacing an existing SSL cert requires a cluster restart. Click to complete the upload.
