设置服务器块后，Nginx不再提供我的域名 [英] After setting up server blocks, Nginx is not serving my domain name
问题描述
我正在将我的MERN应用程序部署到Digital Ocean Droplet(Ubuntu 20.04服务器)上.
我按照以下教程中的步骤安装Nginx.[我已经完成了前面的所有步骤]
但是，设置服务器块后，当我访问 http://sundaray.io 时，出现以下错误.
sundaray.io 是我的域名.
当我运行命令/var/log/nginx/error.log 时，我看到以下内容:
如何解决该错误?
EDIT-1
服务器块为了创建服务器块，我按顺序执行了以下命令:
-
mkdir -p/var/www/sundaray.io/html -
nano/etc/nginx/sites-available/sundaray.io然后，我粘贴了以下配置块.
服务器{听80;听[::]:80;根目录/var/www/sundaray.io/html;index index.html index.htm index.nginx-debian.html;server_name sundaray.io www.sundaray.io;地点/{try_files $ uri $ uri/= 404;}} 错误执行命令 cat/var/log/nginx/error.log 给我以下结果:
EDIT-2
执行 chown -R nginx:nginx/var/www/sundaray.io/html 会引发以下错误:
EDIT-3
执行 ps -elf | grep nginx 会得到以下结果:
EDIT-4 当我执行命令 ls/var/www/sundaray.io/html 时，得到以下结果:
1. chmod 777 从来都不是个好主意.
NGINX在运行用户下运行.如何检查运行用户:
ps -elf | grep nginx .通常是 nginx .代替 777 (向所有人开放)，执行 chmod -R 755/path/to/folder 和 chown -R nginx:nginx/path/to/folder
但是同意.对于故障排除，可以使用它.但是回到您的问题.
2.目录列表已禁用.
错误告诉您nginx无法列出目录内容.这是默认行为.确保
root/var/www/sundaray.io/html; 此路径存在且
index index.html index.htm index.nginx-debian.html; 找到了这些文件之一！
没有这些文件，NGINX无法在/上加载默认的索引文件.在/var/www/sundaray.io/html 中放置一些内容，例如
printf< html> \ n< body> \ n< h1>来自Nginx//h1/\ n</body>/n</html>''>/var/www/sundaray.io/html/index.html&&chown nginx:nginx/var/www/sundaray.io/html/index.html .这应该为您生成一个index.html.
如果您只想测试没有任何文件的服务器配置:
位置/{返回200"Hello on $ host $ uri \ n"；} I am in the process of deploying my MERN app to a Digital Ocean droplet (Ubuntu 20.04 server).
I followed the steps in the following tutorial to install Nginx. [I have completed all the previous steps]
https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-20-04
When I visit http://134.122.112.22, I see the Nginx landing page, as expected.
However, after setting up server blocks, when I visit http://sundaray.io, I get the following error.
sundaray.io is my domain name.
When I run the command /var/log/nginx/error.log, I see the following:
How can I fix the error?
EDIT-1
SERVER BLOCK In order to create the server block, I executed the following commands in order:
mkdir -p /var/www/sundaray.io/htmlnano /etc/nginx/sites-available/sundaray.ioThen, I pasted in the following configuration block.
server {
listen 80;
listen [::]:80;
root /var/www/sundaray.io/html;
index index.html index.htm index.nginx-debian.html;
server_name sundaray.io www.sundaray.io;
location / {
try_files $uri $uri/ =404;
}
}
ERROR
Executing the command cat /var/log/nginx/error.log gave me the following result:
EDIT-2
Executing chown -R nginx:nginx /var/www/sundaray.io/html threw the following error:
EDIT-3
Executing ps -elf |grep nginx gave the following result:
EDIT-4
When I executed the command ls /var/www/sundaray.io/html, I got the following result:
1. chmod 777 is NEVER a good idea.
NGINX operats under a runuser. How to check the runuser:
ps -elf |grep nginx. Normaly it will be nginx. Instead of 777 (Open for everyone) do chmod -R 755 /path/to/folder and chown -R nginx:nginx /path/to/folder
But agree. For troubleshooting it can be used. But back to your problem.
2. Directory-Listing disabled.
The error is telling you nginx can not list the directory content. Which is the default behavior. Make sure
root /var/www/sundaray.io/html;
This path exists AND
index index.html index.htm index.nginx-debian.html;
there are one of these files located!
Without any of these files NGINX can't load the default index file on /. Put something in /var/www/sundaray.io/html like
printf "<html>\n<body>\n<h1>Hello from NGINX</h1>\n</body>\n</html>" > /var/www/sundaray.io/html/index.html && chown nginx:nginx /var/www/sundaray.io/html/index.html. This should generate an index.html for you.
If you just want to test your server configuration without any files:
location / {
return 200 "Hello on $host$uri\n";
}
