本文详细介绍了如何在阿里云ECS上创建一个Discourse论坛。首先通过Putty登录ECS，检查Ubuntu版本并安装git，然后从GitHub下载Discourse Docker镜像。在安装过程中遇到缺少git的问题，更新apt源后成功安装。接下来，找到验证用户的电子邮件服务器，如Mailgun，并配置SMTP设置。将域名或子域名指向阿里云ECS服务器，确保解析正确。最后，安装Discourse论坛时出现访问GitHub的问题导致安装失败。

Step 1: Check the Linux Ubuntu version

root@iZ2ze472xetukni84zf7l3Z:~# uname -a
Linux iZ2ze472xetukni84zf7l3Z 5.4.0-92-generic #103-Ubuntu SMP Fri Nov 26 16:13:00 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
root@iZ2ze472xetukni84zf7l3Z:~#

Step 2: Install git.

root@iZ2ze472xetukni84zf7l3Z:~# sudo apt install git

Package git is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'git' has no installation candidate

Step 3: git the discourse docker from github.

root@iZ2ze472xetukni84zf7l3Z:~# sudo -s
root@iZ2ze472xetukni84zf7l3Z:~# git clone https://github.com/discourse/discourse_docker.git /var/discourse
Cloning into '/var/discourse'...

It's pending in download process... （The server is not in mainland China）


root@iZ2ze472xetukni84zf7l3Z:~# sudo -s

Step 4: Find an email server for verified the users of Discourse.

When the Discourse install, it need to ask for the email server infomation that will be verified the users of the Discourse forum. We can go to the mailgun or other email service like 163, or QQ email services.

Example: Mailgun email Server

Email sending User: postmaster@ms.BigDataSmallTeam.com
password of sending user: ****************
SMTP Settings Server: smtp.mailgun.org
SMTP port: 25,587,465 (SSL/TLS)

Check the github install : discourse/INSTALL-cloud.md at main · discourse/discourse · GitHub

Step 5: Config the domain or sub-domain to the Aliyun ECS server.

Checking the domain bbs.bigdatasmallteam.com in your desktop or laptop.

Step 6 ： Install Discourse forum.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>
