Discourse部署教程-可乐呢o3o

最近在折腾Discourse，此文记录一下安装过程。

官方推荐的是docker部署。

docker安装

[可选]内存不够的添加swap

这里是添加了2GB的swap，并在/etc/fstab文件中添加一行以确保在重启后仍能使用这个swap文件。

sudo dd if=/dev/zero of=/var/swapfile bs=1024 count=2097152
sudo chmod 600 /var/swapfile
sudo mkswap /var/swapfile
sudo swapon /var/swapfile
echo '/var/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

安装nginx

sudo apt install nginx

添加nginx配置

域名换成自己的。

cd /etc/nginx/sites-available
cp default meta.example.com
cd ../sites-enabled
ln -s ../sites-available/meta.example.com

修改nginx配置 vim /etc/nginx/sites-enabled/meta.example.com,将证书换成自己的。
如何使用cloudflare或者阿里云申请证书请参考文章：[还没写呢]

server {
    listen 80;
    server_name meta.example.com;
    return 301 https://$host$request_uri;
}
server {
    listen 443 ssl http2;  
    listen [::]:443 ssl http2;
    server_name meta.example.com;
    client_max_body_size 100M;
    
    location / {
        proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
        proxy_set_header Host $http_host;
        proxy_http_version 1.1; 
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Real-IP $remote_addr;
    }
    ssl_certificate /etc/ssl/meta.example.com/cert.pem;
    ssl_certificate_key /etc/ssl/meta.example.com/key.pem;
    ssl_session_timeout 1d;
    ssl_session_cache shared:SSL:50m;
    ssl_session_tickets off;
    ssl_protocols TLSv1.2;
    ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';
    ssl_prefer_server_ciphers on;
    add_header Strict-Transport-Security max-age=15768000;
    ssl_stapling on;
    ssl_stapling_verify on;
    ssl_trusted_certificate /etc/ssl/meta.example.com/fullchain.pem;
}

nginx重启

service nginx restart

拉取项目

sudo -s
git clone https://github.com/discourse/discourse_docker.git /var/discourse
cd /var/discourse
chmod 700 containers

[自定义]修改 launcher

主要修改95行，如果使用自己打包的image，需要修改此处。

新建Discourse配置文件

新建containers/app.yml

templates:
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/web.template.yml"
  - "templates/web.ratelimited.template.yml"
  - "templates/web.socketed.template.yml"
  
params:
  db_default_text_search_config: "pg_catalog.english"
env:
  LC_ALL: en_US.UTF-8
  LANG: en_US.UTF-8
  LANGUAGE: en_US.UTF-8
  DISCOURSE_HOSTNAME: meta.example.com # 此处修改成你的域名
  DISCOURSE_DEVELOPER_EMAILS: [email protected] # discourse管理员邮箱

  # SMTP配置
  DISCOURSE_SMTP_ADDRESS: smtpdm.aliyun.com # SMTP地址
  DISCOURSE_SMTP_AUTHENTICATION: login # 使用阿里云邮件推送服务需要添加
  DISCOURSE_SMTP_OPENSSL_VERIFY_MODE: none 
  DISCOURSE_SMTP_PORT: 80 # SMTP服务器端口
  DISCOURSE_SMTP_USER_NAME: [email protected] # SMTP用户名
  DISCOURSE_SMTP_PASSWORD: ******** # SMTP密码
  DISCOURSE_SMTP_ENABLE_START_TLS: true
  DISCOURSE_NOTIFICATION_EMAIL: [email protected]
volumes:
  - volume:
      host: /var/discourse/shared/standalone
      guest: /shared
  - volume:
      host: /var/discourse/shared/standalone/log/var-log
      guest: /var/log
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/discourse/discourse-chat-integration.git # 插件，不用的可以不安装

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='[email protected]'" # 如果您想设置首次注册的“发件人”电子邮件地址，把这里邮箱改成你的
  - exec: echo "End of custom commands"

Discourse！启动！

cd /var/discourse
./launcher rebuild app

QA
Q: 报错：Environment: development WARNING: ember-test-selectors: You are using an unsupported ember-cli-babel version. data-test properties are not automatically stripped from your JS code.
A: 增加swap。内存不够了。
