Configuring high availability
GitHub Enterprise Server supports a high availability mode of operation designed to minimize service disruption in the event of hardware failure or major network outage affecting the primary appliance.
In a high availability configuration, a fully redundant secondary GitHub Enterprise Server appliance is kept in sync with the primary appliance through replication of all major datastores.
In an active/passive configuration, the replica appliance is a redundant copy of the primary appliance. If the primary appliance fails, high availability mode allows the replica to act as the primary appliance, allowing minimal service disruption.
After configuration of high availability for お使いの GitHub Enterprise Server インスタンス, you can monitor the status of data replication among to your instance's replica nodes.
メンテナンスやテストのため、またはプライマリアプライアンスが機能しなくなった場合は、コマンドラインを使用して GitHub Enterprise Server レプリカアプライアンスにフェイルオーバーできます。
After failing over to a GitHub Enterprise Server appliance, you should regain redundancy as soon as possible rather than rely on a single appliance.
You can stop replication to a GitHub Enterprise Server replica temporarily, or permanently remove replication.
Geo-replication on GitHub Enterprise Server uses multiple active replicas to fulfill requests from geographically distributed data centers.
