linux - .Net Core 3.1 在 Centos 7 上部署

Question

我正在尝试在 Centos 7 + Plesk 服务器上运行我的 .net Core Web api 应用程序。我的应用程序将在子域中运行。我从 Plesk 面板设置了一个子域并传输了我的文件。之后，我一步一步地按照下面的文章，这不是一篇解释性或帮助性很强的文章。
https://docs.microsoft.com/tr-tr/aspnet/core/host-and-deploy/linux-apache?view=aspnetcore-3.1
首先这个路径不存在/etc/nginx/sites-available/default。于是在其他文章的帮助下，我在etc/nginx/conf.d文件夹下创建了文件api.mysite.com.conf。

To configure Nginx as a reverse proxy to forward HTTP requests to yourASP.NET Core app, modify /etc/nginx/sites-available/default. Open itin a text editor, and replace the contents with the following snippet.

    server {
        listen        80;
        server_name   api.mysite.com *.mysite.com;
        location / {
             .... same as in docs.
        }
    }

其次，我按照文档创建了服务文件。 “/usr/bin/dotnet”这个目录在这一步是不存在的，文件再次不足为奇。
我通过键入“/usr/share/dotnet/dotnet”而不是“/usr/bin/dotnet”解决了这一步。

sudo nano /etc/systemd/system/kestrel-webapi.service

[Unit]
Description=Example .NET Web API App running on Centos 7

[Service]
WorkingDirectory=/var/www/vhosts/mysite.com/api.mysite.com
ExecStart=/usr/share/dotnet/dotnet /var/www/vhosts/mysite.com/api.mysite.com

创建服务后，我运行它没有任何问题。
下一步是 Apache 配置。
https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/linux-apache?view=aspnetcore-3.1

Configuration files for Apache are located within the/etc/httpd/conf.d/ directory. Any file with the .conf extension isprocessed in alphabetical order in addition to the moduleconfiguration files in /etc/httpd/conf.modules.d/, which contains anyconfiguration files necessary to load modules.

我正在“/etc/httpd/conf.d”文件中创建一个配置文件。

<VirtualHost *:*>
    RequestHeader set "X-Forwarded-Proto" expr=${REQUEST_SCHEME}
</VirtualHost>

<VirtualHost *:80>
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:5000/
    ProxyPassReverse / http://127.0.0.1:5000/
    ServerName www.mysite.com
    ServerAlias *.mysite.com
    ErrorLog ${APACHE_LOG_DIR}webapi-error.log
    CustomLog ${APACHE_LOG_DIR}webapi-access.log common
</VirtualHost>

进行此配置后，按顺序运行以下命令时出现错误。

sudo service httpd configtest

sudo systemctl restart httpd

在做这些操作之前，当我通过浏览器打开 api.mysite.com 时，出现了 plesk panel 欢迎页面。我通过编写以下代码解决了这个问题，现在我得到了 403 禁止错误。

mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf_backup

如何解决以上两个问题？当我连接到 api.mysite.com 时，如何重定向到我的 Web api 应用程序？
我已经为此苦苦挣扎了 3 天，我在互联网上找不到合适的文章，有没有人可以帮助我？

Answer 1

我解决了这个问题。
当我们在 plesk 面板中创建域时，apache 会创建自己的配置文件，所以我所要做的就是在 plesk 面板的相关域的 Hosting & DNS 设置下的 Apache & nginx 中更改 Additional apache directives 设置。
Plesk --> 网站和域名 --> <> --> 主机和 DNS --> Apache 和 nginx
HTTP 的附加指令

Header set Access-Control-Allow-Origin "http://yourdomain.com"
Header set Access-Control-Allow-Headers "Access-Control-Allow-Headers, Origin, Accept, 
X-Requested-With, Content-Type, Access-Control-Request-Method, Access-ControlRequest-Headers, Authorization, Content-Disposition"
Header set Access-Control-Allow-Methods "*"
Header set Access-Control-Allow-Credentials "true"
ProxyPreserveHost On
ProxyPass / http://127.0.0.1:5000/
ProxyPassReverse / http://127.0.0.1:5000/

HTTPS 的附加指令

Header set Access-Control-Allow-Origin "https://yourdomain.com"
Header set Access-Control-Allow-Headers "Access-Control-Allow-Headers, Origin, Accept, 
X-Requested-With, Content-Type, Access-Control-Request-Method, Access-ControlRequest-Headers, Authorization, Content-Disposition"
Header set Access-Control-Allow-Methods "*"
Header set Access-Control-Allow-Credentials "true"
ProxyPreserveHost On
ProxyPass / http://127.0.0.1:5000/
ProxyPassReverse / http://127.0.0.1:5000/

如果您有 cors 问题，您可以添加以标题集开头的行。
完成所有这些之后，如果您的服务文件中准备好，您的应用程序将运行。
