# 在windows上安装Discourse全过程
Discourse CentOS 8 全新安装手册
Docker的安装
Git 的基本使用
windows下TensorFlow完整安装流程及出错解决方案
020-群辉OpenVPN配置文件修改
windows 7 安装tensorflow
如何修改 Discourse 的域名
在 Windows 上安装 TensorFlow
kibana安装windows

购买腾讯云在硅谷的云主机，按量计费，半个小时就安装好，总共花费一块钱左右。国内的网络环境安装discourse是不太可能的。

#更新软件列表
sudo apt-get update
#安装包的时候要根据提示输入y确认

  ## Set db_shared_buffers to a max of 25% of the total memory.
  ## will be set automatically by bootstrap based on detected RAM, or you can override
  db_shared_buffers: "128MB"

  ## can improve sorting performance, but adds memory usage per-connection

  #DOCKER_USE_HOSTNAME: true

  ## TODO: List of comma delimited emails that will be made admin and developer
  ## on initial signup example 'user1@example.com,user2@example.com'

  ## The http or https CDN address for this Discourse instance (configured to pull)
  ## see https://meta.discourse.org/t/14857 for details

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git
          - sudo -E -u discourse git clone https://github.com/discourse/discourse-math.git
          - sudo -E -u discourse git clone https://github.com/discourse/discourse-calendar.git
          - sudo -E -u discourse git clone https://github.com/paviliondev/discourse-topic-previews.git

## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: rails r "SiteSetting.notification_email='mapengfei@mail.nwpu.edu.cn'"
  - exec: echo "End of custom commands"

编译好以后，最终会下面这个命令。把编译好的镜像放到本地，然后将刚才的命令复制到windows命令行里，discourse就能运行了http://localhost/。
