【问题描述】：

我看到已经有关于这个主题的帖子，但尽管尝试了我仍然做不到。

我想通过 AWS ec2 启动 nginx。下载 nginx 时，我没有 sites-enabled 和 sites-workable 文件夹，所以我按照此处的说明 (nginx missing sites-available directory) 创建文件并在 nginx.config 的 http 中添加 include 行。我还创建了符号链接。

但是没有成功...当我使用 sudo /etc/init.d/nginx restart 重新启动服务器时出现以下错误

"正在启动 nginx: nginx: [emerg] 未知指令 "listen:" in /etc/nginx/sites-enabled/react-flask-app.conf:2"

这是我的 /etc/nginx/sites-enabled/react-flask-app.con 文件：

server 
       listen: 80;
       root /home/ec2-user/cecs470-web-app-project-team2/test/testest/build;
       index index.html;

       location: / 
             try_files $uri $uri/ =404;
       

这是我的 /etc/nginx/nginx.conf 文件。

你有线索吗？谢谢

【问题讨论】：

指令应该是listen和location，不是listen:和location:。

看下面的答案

哦，谢谢！现在我有另一个问题，我的网站无法加载，我仍然有默认网站，你知道为什么吗？我停止并启动 nginx

您能否将新错误发布为更新，因为该错误已解决并选择一个答案

【参考方案1】：

来自以下文件的监听指令

my /etc/nginx/sites-enabled/react-flask-app.con

应该是

 listen 80;

你的有:
