甲骨文免费的 ARM 4C24G 的机器只用来搭梯子就大材小用了,这里结合博主自身的体验,说说如何榨干它。

以下均基于 Debian 11 root 用户 。

Pre-install

安装 Docker、Nginx 请查看系列 1

榨干 Orcale ARM 1/ Gitlab

安装 Mastodon

新建文件夹

mkdir -p /var/www/mastodon && cd /var/www/mastodon

编辑 docker-compose.yml

vim docker-compose.yml

将下方代码粘贴进去,按 Esc,输入 :wq 保存退出

配置数据库

docker run --name postgres12 -v /var/www/mastodon/postgres:/var/lib/postgresql/data -e   POSTGRES_PASSWORD=设置数据库管理员密码 --rm -d postgres:12.5-alpine

检查 postgres 文件夹,应该出现 postgres 相关的多个文件,不是空文件夹。

然后执行

docker exec -it postgres12 psql -U postgres

输入

CREATE USER mastodon WITH PASSWORD '数据库密码(最好和数据库管理员密码不一样)' CREATEDB;

创建 mastodon 用户,然后停止 docker

docker stop postgres12

配置 .env.production

# 回到 mastodon 文件夹
cd /var/www/mastodon

# 生成文件
touch .env.production

# 配置文件
dc run --rm web bundle exec rake mastodon:setup
  1. 输入域名
  2. Enable single user mode? 否
  3. Using Docker to run Mastodon? 是
  4. postsql 用户名、数据库名填 mastodon ,密码部分填刚刚设置的数据库密码
  5. redis 部分都直接回车
  6. Store uploaded files on the cloud? 这个可填否,如有需要可配置 S3。
  7. Send e-mails from localhost? 否。然后填入邮件服务设置,推荐使用 Mailazy具体配置可参照下方
  8. This configuration will be written to .env.production Save configuration? 是
  9. 然后会出现 .env.production 配置,复制下来,先存到电脑里,等会用
  10. 然后会要你建立数据库和编译,都选是。最后建立管理员账号。

成功之后,编辑 .env.production 文件,复制上方保存的配置信息,按 Esc,输入 :wq 保存退出

vim .env.production

S3 及 SMTP 信息大致如下

S3_ENABLED=true
S3_PROTOCOL=https
S3_REGION=fr-par
S3_ENDPOINT=https://s3.fr-par.scw.cloud
S3_HOSTNAME=[hidden].s3.fr-par.scw.cloud
S3_BUCKET=[hidden]
AWS_ACCESS_KEY_ID=[hidden]
AWS_SECRET_ACCESS_KEY=[hidden]
S3_ALIAS_HOST=[hidden]
SMTP_SERVER=smtp.mailazy.com
SMTP_PORT=587
SMTP_LOGIN=[hidden]
SMTP_PASSWORD=[hidden]
SMTP_AUTH_METHOD=plain # 该配置仅代表可用于 mailazy,若为其他服务商请做相应更改
SMTP_OPENSSL_VERIFY_MODE=none # 该配置仅代表可用于 mailazy,若为其他服务商请做相应更改
SMTP_FROM_ADDRESS=mastodon@[hidden]

运行

dc up -d

为相应文件夹赋权

chown 991:991 -R ./public
chown -R 70:70 ./postgres

# 关闭
dc down

# 再次启动
dc up -d

查看运行详情

dc ps

配置 Nginx

创建配置文件

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

复制下方 http 配置信息以申请 SSL 证书,按 Esc,输入 :wq 保存退出

server {
  listen 80;
  # 若配置了 IPV6,删除下方的井号
  # listen [::]:80;
  server_name mastodon.im.sb;
  root /var/www/mastodon/public;
  location /.well-known/acme-challenge/ { allow all; }
  location / { return 301 https://$host$request_uri; }
}

# 将 mastodon.im.sb 替换成您自己的域名

重载 Nginx

nginx -t
# 确保配置文件无异常
# nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
# nginx: configuration file /etc/nginx/nginx.conf test is successful

# 重载
nginx -s reload

将您的域名 A 记录及 AAAA 记录(若有)指向服务器 IP,然后申请域名证书

acme.sh --issue -d mastodon.im.sb -w /var/www/mastodon/public --server letsencrypt

# 可选,申请 ECC 证书
acme.sh --issue -d mastodon.im.sb -w /var/www/mastodon/public -k ec-256 --server letsencrypt

# 将 mastodon.im.sb 替换成您自己的域名

再次编辑配置文件

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

复制下方完整配置信息,按 Esc,输入 :wq 保存退出
