1. Setup an external database

+
+

+ This {{settings.appName}} installation is currently configured to use the built-in database server, but HA requires a standalone installation of MySQL. +

+

+

    +
  • + Setup an external database instance. +
      +
    • This can be a hosted solution like Amazon RDS or Google Cloud SQL,
      • +
    • Or a self-hosted instance or multi-master cluster.
      • +
    +
    • +
  • Click the export button below to export the entire contents of the current database.
    • +
  • Import the data into the new external database.
    • +
+

+

+ +

Uncompressed Size: {{format-mib model.haConfig.dbSize}}

+

+ {{else}} +

1. Setup an external database

+

+ Complete, running off of an external database. +

+ {{/if}} +
+ +
+ {{#if isLocalDb}} +

2. Use the new external database

+
+
    +
  • Re-launch the server container pointed at the external database: + {{code-block code=runCode language="bash" constrained=false}} +
    • + {{#unless settings.isPrivateLabel}} +
  • + See docs for more detail. +
    • + {{/unless}} +
+ {{else}} +

2. Use the new external database

+

+ Complete, {{model.haConfig.dbHost}} will be used as the external database for HA. +

+ {{/if}} +
+ +
+ {{#if justGenerated}} +

3. Generate HA config script

+

+ Complete. +
