🌠 搭建 Mastodon 实例 | How to install a Mastodon instance

Mastodon 官方文档更新了 Mastodon 的安装说明，现将其翻译成中文，以便更多 Mastodon 爱好者自行搭建。

先决条件

  • 运行 Ubuntu 18.10 的独立服务器或者内存大于 2G 基于 KVM/XEN 等的 VPS（若内存小于 2G，推荐设置个 SWAP），且具备 root 权限
  • 一个域名（顶级或二级域名）
  • 推荐使用 Mailgun 进行邮件的发送

安装系统程序

Nodejs 、 Yarn & System packages

apt update && apt install curl -y && curl -sL https://deb.nodesource.com/setup_10.x | bash - && curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
apt update && apt install -y vim imagemagick ffmpeg libpq-dev libxml2-dev libxslt1-dev file git-core g++ libprotobuf-dev protobuf-compiler pkg-config nodejs gcc autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm5 libgdbm-dev nginx redis-server redis-tools postgresql postgresql-contrib certbot yarn libidn11-dev libicu-dev libjemalloc-dev

安装 Ruby

新建 Mastodon 用户

adduser --disabled-login mastodon

切换至 Mastodon 用户

su – mastodon

安装 rbenv & rbenv-build

git clone https://github.com/rbenv/rbenv.git ~/.rbenv
cd ~/.rbenv && src/configure && make -C src
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec bash
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

安装最新 Ruby 版本 （截至本文发布，最新版本为 2.7.7）

RUBY_CONFIGURE_OPTS=--with-jemalloc rbenv install 2.7.2
rbenv global 2.6.6

返回至 root 用户

exit

设置

设置 PG 数据库

新建 Mastodon 数据库用户

sudo -u postgres psql
CREATE USER mastodon CREATEDB;
\q

架设 Mastodon

切换至 Mastodon 用户

su - mastodon

克隆代码至本地

git clone https://github.com/tootsuite/mastodon.git live && cd live
git checkout $(git tag -l | grep -v 'rc[0-9]*$' | sort -V | tail -n 1)

安装 Bundler

gem install bundler --no-ri --no-rdoc

安装依赖

bundle install -j$(getconf _NPROCESSORS_ONLN) --deployment --without development test
yarn install --pure-lockfile

生成配置文件

RAILS_ENV=production bundle exec rake mastodon:setup

这句代码会执行:

  • 创建一个配置文件，叫 .env.production
  • 预生成静态文件
  • 创建数据库并同步

退出至 root 用户

exit

配置 Nginx

vim /etc/nginx/conf.d/mastodon.conf

复制下方内容进去

map $http_upgrade $connection_upgrade {
  default upgrade;
  ''      close;
}

proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=CACHE:10m inactive=7d max_size=1g;

server {
  listen 80;
  listen [::]:80;
  server_name example.com;
  root /home/mastodon/live/public;
  location /.well-known/acme-challenge/ { allow all; }
  location / { return 301 https://$host$request_uri; }
}

server {
  listen 443 ssl http2;
  listen [::]:443 ssl http2;

  keepalive_timeout    70;
  sendfile             on;
  client_max_body_size 80m;

  root /home/mastodon/live/public;

  gzip on;
  gzip_disable "msie6";

  location / {

  }

  location ~ ^/(emoji|packs|system/accounts/avatars|system/media_attachments/files) {

    add_header Strict-Transport-Security "max-age=31536000";
    try_files $uri @proxy;
  }

  location /sw.js {
    add_header Cache-Control "public, max-age=0";
    add_header Strict-Transport-Security "max-age=31536000";

    proxy_pass http://127.0.0.1:3000;
    proxy_buffering on;
    proxy_redirect off;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;

    tcp_nodelay on;
  }

  location /api/v1/streaming {
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto https;
    proxy_set_header Proxy "";

    proxy_pass http://127.0.0.1:4000;
    proxy_buffering off;
    proxy_redirect off;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;

    tcp_nodelay on;
  }

  error_page 500 501 502 503 504 /500.html;
}

替换其中的  example.com 为你自己的域名，然后重启 Nginx

systemctl reload nginx

使用 Let’s Encrypt 生成 SSL 证书（生成之前将域名指向你服务器/VPS 的 IP，能访问了后再执行下面的代码）

certbot certonly --webroot -d example.com -w /home/mastodon/live/public/

然后编辑Nginx 配置文件将 SSL 相关行的 # 给删除掉

vim /etc/nginx/conf.d/mastodon.conf

大约在第 28、29行，删除前面的 #

  # Uncomment these lines once you acquire a certificate:
  # ssl_certificate     /etc/letsencrypt/live/example.com/fullchain.pem;
  # ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

再次重启 Nginx

systemctl reload nginx

配置系统服务使 Mastodon 能自动运行

cd /etc/systemd/system/ && wget https://github.com/tootsuite/mastodon/raw/master/dist/mastodon-web.service && wget https://github.com/tootsuite/mastodon/raw/master/dist/mastodon-streaming.service && wget https://github.com/tootsuite/mastodon/raw/master/dist/mastodon-sidekiq.service
systemctl start mastodon-web mastodon-sidekiq mastodon-streaming
systemctl enable mastodon-*

Mastodon 即会自行启动，访问你的域名即可看到熟悉的 Mastodon 页面
