nginx 绑定失败

当我运行 nginx 时，出现错误，

nginx 从 npm run scripts 启动

我运行了 npm run start-prod scripts:start-prod:有以下命令

 concurrently --no-color "uwsgi --ini build/docker/uwsgi.ini" "nginx"  "npm run render-prod"

npm run render-prod 脚本的值为“render-prod”：“babel-node node/react-render.jsx”

请帮我修复这个 nginx 绑定错误。

短暂性脑缺血发作，

谨致问候，Bharath AK

答案1

其他一些进程已在监听端口 80。这可能意味着您已有一个 Apache 进程正在运行。

您可以使用此建议的命令来找出可能正在监听该端口的内容：

sudo lsof -i :80 | grep LISTEN

注意：在极少数情况下，可能存在单独的 nginx 正在监听该端口，例如，如果您手动启动了 nginx 守护程序（不推荐）或者您修改了 nginx 运行的用户（不推荐）。不过，更有可能的是，其他应用程序正在监听该端口。

Ubuntu 允许您同时安装两个 Web 服务器，因为可以将它们配置为监听不同的端口。如果不这样做，其中一个或另一个服务器将无法启动。

正如 @thomasrutter 所说，检查使用的端口sudo lsof -i -P -n并检查在哪里port 80使用。如果不需要该进程，请终止该进程并nginx再次使用检查配置sudo nginx -t。另一件事是您想在浏览器上检查您的页面，然后在运行您的页面后，您可以编辑服务器块nginx.conf或sites-available/default块，您可以将您的页面代理传递address:port到其中，port 80这样您只需点击端口的公共 IP 地址，然后您就可以在浏览器上看到该页面。
