使用项目：nostr relay 一个python写的程序

1. 使用pip安装：pip install nostr-relay

2. 新建一个目录mkdir /opt/nostr，并进入目录 cd /opt/nostr

3. 创建一个配置文件，参考官方默认配置 ，我的配置如下，修改了一点

   DEBUG: false
   ​
   relay_name: python relay
   relay_description: relay written in python
   sysop_pubkey: 
   sysop_contact: 
   ​
   storage:
     sqlalchemy.url: sqlite+aiosqlite:///nostr.sqlite3
     # the number of concurrent REQ queries sent to the db
     num_concurrent_reqs: 10
     # the number of concurrent event saves. (sqlite can only support 1 writer at a time)
     num_concurrent_adds: 2
     validators:
       - nostr_relay.validators.is_not_too_large
       - nostr_relay.validators.is_signed
       - nostr_relay.validators.is_recent
       - nostr_relay.validators.is_not_hellthread
   ​
   verification:
     # options are disabled, passive, enabled
     nip05_verification: disabled
     expiration: 86400 * 30
     update_frequency: 3600
     #blacklist:
     # - badhost.biz
     #whitelist:

   gunicorn:
     bind: 127.0.0.1:6969
     workers: 1
     loglevel: info
     reload: false
   ​
   ​
   purple:
     host: 127.0.0.1
     port: 6969
     workers: 1
     disable_compression: true
   ​
   ​
   # see docs/authentication.md
   authentication:
     enabled: false
     relay_urls: 
       - ws://localhost:6969
       - ws://127.0.0.1:6969
       # 可以换成 ws://公网IP:6969
       - wss://yourdomain.name
     actions:
       save: a
       query: a
   ​
   # number of seconds to allow between client messages
   message_timeout: 1800
   ​
   # number of open subscriptions per connection
   subscription_limit: 32
   ​
   # set this to a private key used for internal control events
   # service_privatekey: 9627da965699a2a3048f97b77df5047e8cd0d11daca75e7687d0b28b65416a3c
   ​
   # set this to limit the number of events returned per REQ
   max_limit: 6000
   ​
   # set this to the maximum number of "p" tags in an event
   hellthread_limit: 100

4. 使用你喜欢的反向代理工具，配合域名使用。

5. 使用systemd管理

   1. 创建service文件 vim /etc/systemd/system/nostr-relay.service

   2. 内容为

      [Unit]
      Description=Nostr Relay Service
      After=network.target
      ​
      [Service]
      Type=simple
      User=root
      WorkingDirectory=/opt/nostr
      ExecStart=/usr/local/bin/nostr-relay -c /opt/nostr/config.yaml serve
      Restart=always
      RestartSec=5
      StandardOutput=append:/opt/nostr/nostr-relay.log
      StandardError=append:/opt/nostr/nostr-relay-error.log
      ​
      [Install]
      WantedBy=multi-user.target

   3. 保存并退出。

   4. 重载systemd服务 systemctl daemon-reload

   5. 启动并查看运行情况

      systemctl start nostr-relay
      systemctl status nostr-relay

   6. 设置开机自启 systemctl enable nostr-relay
