更改您的 Discourse 域名或重命名

:bookmark: 本指南说明如何更改您的 Discourse 站点的域名,并包含有关设置 DNS 更改、编辑配置文件、更新站点设置以及更正社交登录和帖子内容以反映新域名信息。

:warning: 本指南适用于使用我们在 GitHub 上的安装指南安装的自托管 Discourse 实例。如果您由 Discourse 托管,请参阅 Configure your domain name for hosted Discourse 获取具体说明。

您可能最终想要更改 Discourse 实例的域名,例如从

=BEFORE= :right_arrow: =AFTER=

让我们开始吧。

提前将 DNS TTL 设置得较低

首先,将 DNS 的生存时间 (TTL) 设置为一个较小的值,例如 60 分钟。这应该在实际更改域名前几天完成,以确保更改能够快速在互联网上传播。

从任何站点设置中删除旧域名

访问您的 Discourse 管理界面中的 /admin/site_settings,搜索包含旧域名的任何设置。将这些设置更新为新域名。

更改 DNS 记录

更新您的 DNS 设置,禁用旧域名并将新域名指向您的 Discourse 服务器的 IP 地址。

app.yml 中编辑站点名称

您可以手动编辑 app.yml 文件以输入新的域名信息。

以下是手动编辑的方法:

cd /var/discourse
nano containers/app.yml

找到以下行并替换它:

DISCOURSE_HOSTNAME: 'your.newdomain.com'

如果使用了内容分发网络 (CDN),请通过注释掉 app.yml 中相应的行来暂时禁用它。使用以下命令重建您的 Discourse 站点:

./launcher rebuild app

:information_source: 或者,您可以再次运行 ./discourse-setup 并输入新的域名信息,而不是编辑 app.yml

检查您的站点在新域名下是否可以正常运行。

修复社交登录

:exclamation: 根据您的登录方式,您可能需要先执行此操作,否则更改名称后您将无法登录。

如果您使用社交登录,请在平台上(Twitter、Facebook、Google、GitHub)更新凭据以反映新域名。请参阅 Discourse how-to 类别中的指南。

重新映射帖子中的域名

所有现有帖子仍将引用旧域名。

您需要将帖子中对旧域名的引用更改为新域名:

./launcher enter app

然后

discourse remap =BEFORE= =AFTER=

用以下命令完成:

rake posts:rebake

这确保了域名在现有帖子中被重新映射,并且内容会根据需要重新生成。

:information_source: 如果您有 CDN,请记住在更改域名后重新激活它。
