安装discourse

mkdir /var/discourse
git clone https://github.com/discourse/discourse_docker.git /var/discourse
cd /var/discourse
cp samples/standalone.yml containers/app.yml

修改app.yml文件

文件修改如果错了，再重新编绎非常花时间，所以最好一次搞定，还是就是邮箱非常重要，填写真实的。

templates:
– "templates/postgres.template.yml"
– "templates/redis.template.yml"
– "templates/sshd.template.yml"
– "templates/web.template.yml"
– "templates/web.china.template.yml"

配置文件的这个部分，需要添加- “templates/web.china.template.yml”;否则在./launcher bootstrap app初始化时会报错RuntimeError: …，原因得问GWF。

## on initial signup example'user1@example.com,user2@example.com'
DISCOURSE_DEVELOPER_EMAILS: 'henry@outlook.com'

这里是开发者邮箱的设置，用于接收discoures论坛的官方邮件，只针对开发运营这个论坛的开发者。

## TODO: The domain name this Discourse instance will respond to
DISCOURSE_HOSTNAME: 'weifuwu.ren'

域名设置没设么可说的，没有的话，用绑定的外网IP地址访问discourse也可以，购买了域名可以按照指南到域名管理界面，进行设置；

DISCOURSE_SMTP_ADDRESS:smtp.mxchina.com
DISCOURSE_SMTP_PORT:25
DISCOURSE_SMTP_USER_NAME: info@weifuwu.ren
DISCOURSE_SMTP_PASSWORD: xxxxxxx
DISCOURSE_SMTP_ENABLE_START_TLS: true
DISCOURSE_SMTP_AUTHENTICATION: login
DISCOURSE_SMTP_OPENSSL_VERIFY_MODE: none

重点是在邮箱设置，我申请的阿里云邮箱

– DISCOURSE_SMTP_PASSWORD: xxxxxxx设置的就是邮箱密码；
– DISCOURSE_SMTP_PORT:端口设置25，
– DISCOURSE_SMTP_ADDRESS:Host是smtp.mxchina.com,

DISCOURSE_SMTP_USER_NAME: 这里的设置最最重要的，这个邮箱又叫notification email 被用于发送所有重要系统邮件的邮箱地址。指定的域名必须正确设置 SPF、DKIM 和反向 PTR 记录以发送邮件。一般和域名绑定在一起，比如info@weifuwu.com 或者 admin@weifuwu.com 都行，这样收到邮件的发帖人或回复人感觉比较正式，使用这个邮箱也是最频繁的。关于SPF、DKIM设置有篇文章可参考1
如果您使用的阿里云的企业邮箱，域名解析后可以不用设置 SPF、DKIM 了已经设置好了，注意阿里云这里设置DISCOURSE_SMTP_ADDRESS:smtp.mxhichina.com

使用代理

因为国内网络环境的问题，./launcher rebuild app 操作经常卡壳，这时就需要配置个代理：discourse服务器上使用代理

编辑app.yml在env:下添加代理地址：

1
2
HTTP_PROXY: http://example.org:12345
HTTPS_PROXY: http://example.org:12345

加入国内镜像

1
2
3
echo "DOCKER_OPTS=\"\$DOCKER_OPTS –registry-mirror=https://docker.mirrors.ustc.edu.cn\"" | sudo tee -a /etc/default/docker

sudo service docker restart

初始化discourse

1
2
3
./launcher bootstrap app
# 启动discourse服务，就OK了！
./launcher start app

手动创建管理员账户

1

5
./launcher enter app

rake admin:create

exit

访问网站地址，成功打开就完成了

扩展安装

用 Let’s Encrypt 添加 https 证书

添加模板

添加 web.ssl.template.yml 和 web.letsencrypt.ssl.template.yml 模板

注意：如果你正在使用 web.socketed.template.yml ，不用继续看这篇了。
你应该在主机上设置 Let’s Encrypt 的客户端。客户端无法在 unix socket 上进行验证。

在app.yml文件中添加

1
2

4
templates:
  - "templates/web.template.yml"
  - "templates/web.ssl.template.yml"
  - "templates/web.letsencrypt.ssl.template.yml"

暴露 443 端口

1
2
3
expose:
  - "80:80"
  - "443:443"

给 Let’s Encrypt 添加个注册用邮箱账号

1
2
env:
  LETSENCRYPT_ACCOUNT_EMAIL: email@awesomedomain.com

运行rebuild命令

1
./launcher rebuild app

修改文章的永久链接

Replace all instances of the old name with the new name in posts

All the existing posts will still refer to the old domain. Let’s fix that:

1
2
3
./launcher enter app
discourse remap talk.foo.com talk.bar.com
rake posts:rebake

This remaps text in posts from the old URL to the new URL, then regenerates all posts just in case.
