# Activate GitLab EE with a license[](#activate-gitlab-ee-with-a-license-starter-only "Permalink")
要激活所有 GitLab 企业版(EE)功能,您需要上传许可证. 从 GitLab Inc.获得许可证后,您可以通过**以管理员身份登录到 GitLab 实例**或在安装时添加许可证来上载许可证.
许可证的形式为 base64 编码的 ASCII 文本,扩展名为`.gitlab-license` ,可以在[购买](https://about.gitlab.com/pricing/) `.gitlab-license`或注册[免费试用时获得](https://about.gitlab.com/free-trial/) .
**注意:**从 GitLab Enterprise Edition 9.4.0 开始,没有上载许可证的新安装实例将仅具有核心功能. 试用许可证将激活所有 Ultimate 功能,但是[试用期满后](#what-happens-when-your-license-expires) ,某些功能将被锁定.
## Uploading your license[](#uploading-your-license "Permalink")
首次访问以 admin 身份登录的 GitLab EE 安装时,您会看到一条注释,敦促您上传许可证,并带有一个链接,该链接可直接转到**Admin Area> License** .
否则,您可以:
1. 通过单击菜单栏中的扳手图标,手动导航到**管理区域** .
[![Admin Area icon](https://img.kancloud.cn/42/0c/420cc1f43793de313fd2f09b0ab641ec_539x35.png)](img/admin_wrench.png)
2. 然后转到" **许可证"**选项卡,然后单击"上**载新许可证"** .
[![License Admin Area](https://img.kancloud.cn/a3/c0/a3c0d684b63e9c5bf523fde0b6b2662b_1226x572.png)](img/license_admin_area.png)
3. 如果您收到`.gitlab-license`文件,则应该已经将其下载到本地计算机中. 然后,您可以通过选择许可证文件并单击"上**载许可证"**按钮直接上载它. 在下图中,您可以看到所选的许可证文件名为`GitLab.gitlab-license` .
[![Upload license](https://img.kancloud.cn/5f/6f/5f6f56ede053bd4df636fc08ebc05d35_868x281.png)](img/license_upload.png)
如果您以纯文本格式收到许可证,则需要选择"输入许可证密钥"选项,复制许可证,将其粘贴到"许可证密钥"字段中,然后点击**上传许可证** .
## Add your license at install time[](#add-your-license-at-install-time "Permalink")
通过将名为`Gitlab.gitlab-license`的文件放置在`/etc/gitlab/`对于 Omnibus)或`config/`对于源代码安装,可以在安装时自动导入`Gitlab.gitlab-license` .
还可以为许可证指定自定义位置和文件名.
源代码安装应使用有效的 GitLab Enterprise Edition 许可证的路径设置`GITLAB_LICENSE_FILE`环境变量.
```
export GITLAB_LICENSE_FILE="/path/to/license/file"
```
Omnibus 安装应将此条目添加到`gitlab.rb` :
```
gitlab_rails['initial_license_file'] = "/path/to/license/file"
```
**警告:**这些方法只会在安装时添加许可证. 使用 Web 用户界面中的"管理区域"来续订或升级许可证.
* * *
许可证上载后,所有 GitLab 企业版功能都将处于激活状态,直到许可证期结束. 该时间段结束后,该实例将[恢复](#what-happens-when-your-license-expires)为仅 Core 功能.
您可以随时在"管理区域"的"许可证"部分中查看许可证详细信息.
[![License details](https://img.kancloud.cn/36/52/3652effc3e59cf423eb5ba8735fbc6c4_1000x855.png)](img/license_details.png)
## Notification before the license expires[](#notification-before-the-license-expires "Permalink")
许可证到期前一个月,GitLab 管理员将开始看到一条消息,通知到期时间. 确保您更新了许可证,否则,如果许可证过期,您将错过所有付费功能.
## What happens when your license expires[](#what-happens-when-your-license-expires "Permalink")
万一您的许可证过期,GitLab 将锁定某些功能,如 Git 推送,问题创建等,并且将向所有管理员显示一条消息,告知已过期的许可证.
为了恢复所有以前的功能,必须上载新的许可证. 要退回到仅激活核心功能,您需要删除过期的许可证.
## License history[](#license-history "Permalink")
可以上传和查看多个许可证,但是只有最新的许可证将用作活动许可证.
## Troubleshooting[](#troubleshooting "Permalink")
### There is no License tab in the Admin Area[](#there-is-no-license-tab-in-the-admin-area "Permalink")
如果您最初安装的是 Community Edition,而不是 Enterprise Edition,则需要在[升级](../../update/README.html#community-to-enterprise-edition)许可证之前[升级到 Enterprise Edition](../../update/README.html#community-to-enterprise-edition) .
GitLab.com 用户无法上传和使用自我管理的许可证. 如果您希望在 GitLab.com 上使用付费功能,则可以[购买](../../subscriptions/index.html#subscribe-to-gitlabcom)单独的订阅.
### Users exceed license limit upon renewal[](#users-exceed-license-limit-upon-renewal "Permalink")
如果您在续订之前将新用户添加到您的 GitLab 实例中,则可能需要购买额外的席位来覆盖这些用户. 如果是这种情况,并且上传了没有足够用户的许可证,则会显示一条消息,提示您购买其他用户. 有关如何确定所需用户数以及如何增加其他席位的更多信息,请参见[许可常见问题解答](https://about.gitlab.com/pricing/licensing-faq/) .
