我一直在尝试建立一个可以在运行 Ubuntu 的计算机上运行的网站。到目前为止，我已经设法解决了大部分问题，我认为我已经接近完成这个东西的上线。我尝试安装和运行的网站名为 WriteFreely（这是一个极简主义的博客平台，我和其他人可以注册并开始写博客，而不会受到干扰。
我已在此处遵循该指南：https://writefreely.org/start并一直成功到标题启动服务。我正在运行 Ubuntu 18.04，因此遵循以下说明：通过在 /etc/systemd/system/writefreely.service 创建文件来创建 Systemd 服务：。我假设我需要打开文本编辑器，创建一个名为 writefreely.service 的 .service 文件，然后复制并粘贴服务脚本：
[Unit]
Description=WriteFreely Instance
After=syslog.target network.target
# If MySQL is running on the same machine, uncomment the following
# line to use it, instead.
#After=syslog.target network.target mysql.service
[Service]
Type=simple
StandardOutput=syslog
StandardError=syslog
WorkingDirectory=/var/www/example.com
ExecStart=/var/www/example.com/writefreely
Restart=always
[Install]
WantedBy=multi-user.target
在提供的文档中，它告诉您将 /var/www/example.com 更改为您自己的域名。我通过转到 /var/www/ 并在 (amcosy.club) 中创建了一个包含我的域名的文件夹，然后将最新的 writefreely 文件夹移动到这个新创建的文件夹中。
现在，我真的不知道该怎么做。我输入了sudo systemctl start writefreely，它要求我输入密码，然后什么也没发生。我认为这是正常的。下一个输入是使用 验证应用程序日志sudo journalctl -f -u writefreely。这将返回以下内容：
-- Logs begin at Wed 2020-04-08 00:01:21 BST. --

如果这太明显了，我很抱歉，但我真的不擅长这些。如果我需要提供更多详细信息，请告诉我！非常感谢任何能提供见解的人！
