GitHub Enterprise 提供了两个部署选项。 除了 GitHub Enterprise Server 之外，您还可以使用 GitHub Enterprise Cloud 在 GitHub.com 上托管企业的开发工作。 更多信息请参阅“GitHub 的产品”。
GitHub uses a unique-user licensing model. For enterprise products that include multiple deployment options, GitHub determines how many licensed seats you're consuming based on the number of unique users across all your deployments.
Each user account only consumes one license, no matter how many GitHub Enterprise Server instances the user account uses, or how many organizations the user account is a member of on GitHub Enterprise Cloud. This model allows each person to use multiple GitHub Enterprise deployments without incurring extra costs.
To ensure the same user isn't consuming more than one license for multiple enterprise deployments, you can synchronize license usage between your GitHub Enterprise Server and GitHub Enterprise Cloud deployments.
In order to use a GitHub Enterprise Server instance, you must upload a license file that GitHub provides when you purchase, renew, or add user licenses to GitHub Enterprise.
For a person using multiple GitHub Enterprise environments to only consume a single license, you must synchronize license usage between environments. Then, GitHub will deduplicate users based on the email addresses associated with their user accounts. Multiple user accounts will consume a single license when there is a match between an account's primary email address on GitHub Enterprise Server and/or an account's verified email address on GitHub.com. For more information about verification of email addresses on GitHub.com, see "Verifying your email address" in the GitHub Enterprise Cloud documentation.
When you synchronize license usage, only the user ID and email addresses for each user account on GitHub Enterprise Server are transmitted to GitHub Enterprise Cloud. For more information, see "Syncing license usage between GitHub Enterprise Server and GitHub Enterprise Cloud."
When you purchase or renew GitHub Enterprise, GitHub provides a license file for 您的 GitHub Enterprise Server 实例. A license file has an expiration date and controls the number of people who can use 您的 GitHub Enterprise Server 实例. After you download and install GitHub Enterprise Server, you must upload the license file to unlock the application for you to use.
For more information about downloading your license file, see "Downloading your license for GitHub Enterprise."
For more information about uploading your license file, see "Uploading a new license to GitHub Enterprise Server."
If your license expires, you won't be able to access GitHub Enterprise Server via a web browser or Git. If needed, you will be able to use command-line utilities to back up all your data. For more information, see "Configuring backups on your appliance."
If you have any questions about renewing your license, contact GitHub' 销售团队.
