Nginx 找不到具体位置
[英]Nginx can't find specific location
问题描述
I'm trying to run django + gunicorn + nginx by using docker-compose .
我正在尝试使用 docker-compose 运行 django + gunicorn + docker-compose 。
django and gunicorn now are working correctly and response to request, but, when I try to access to project within nginx (port 80), it can't find my project location. django 和 gunicorn 现在工作正常并响应请求，但是，当我尝试访问 nginx（端口 80）中的项目时，它找不到我的项目位置。
following are nginx Dockerfile and nginx.conf :以下是 nginx Dockerfile和nginx.conf ：
FROM nginx:1.17.4-alpine
RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d/
and nginx.conf :和nginx.conf ：
upstream back {
# in docker-compose.yml file, (django+gunicorn) service name is `backend` and is listening on port 8000.
server backend:8000;
}
server {
listen 80;
location /backend {
proxy_pass http://back;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
}
Now, gunicorn is listening on port 8000 and responses to requestes.现在，gunicorn 正在监听 8000 端口并响应请求。 if I go to 127.0.0.1 , I see nginx default page.如果我 go 到127.0.0.1 ，我看到 nginx 默认页面。 But if I go to 127.0.0.1/backend/ , nginx shows me 404 page.但如果我 go 到127.0.0.1/backend/ ， nginx 显示我 404 页。
in docker-compose logs it shows me following line:在 docker-compose 日志中，它显示了以下行：
[error] 6#6: *1 open() "/usr/share/nginx/html/backend" failed (2: No such file or directory), client: 192.168.176.1, server: localhost, request: "GET /backend HTTP/1.1", host: "127.0.0.1" <br>
It seems, nginx are searching for /backend in his folders in usr/share and does not pass request to port 8000. How can I solve this problem?看来，nginx 正在他的usr/share文件夹中搜索/backend并且没有将请求传递到端口 8000。我该如何解决这个问题？
UPDATE更新
this is docker-compose.yml file:这是docker-compose.yml文件：
version: '3'
services:
db:
...
redis:
...
backend:
hostname: backend
depends_on:
- db
- redis
volumes:
- ./backend/app/:/opt/
build:
context: .
dockerfile: ./backend/Dockerfile
working_dir: /opt/app/project
command: gunicorn config.wsgi:application --bind 0.0.0.0:8000
env_file:
- ./backend/.env
ports:
- 8000:8000
nginx:
image: nginx
build:
context: .
dockerfile: ./nginx/Dockerfile
ports:
- 80:80
depends_on:
- backend

I'm not very familiar with gunicorn , but your configuration looks basically correct.我对gunicorn不是很熟悉，但是您的配置看起来基本正确。
When nginx does the proxy_pass , the path /backend is also proxy_pass 'ed to your backend -service.当nginx执行proxy_pass时， path /backend也是proxy_pass到您的backend服务的。
I assume, that your gunicorn does not know how to handle the /backend -path?我假设，您的gunicorn不知道如何处理/backend -path？
Maybe it would help, if you rewrite everything to / :如果您将所有内容重写为/ ，也许会有所帮助：
nginx.conf : nginx.conf ：
upstream back {
# in docker-compose.yml file, (django+gunicorn) service name is `backend` and is listening on port 8000.
server backend:8000;
}
server {
listen 80;
location /backend {
# # # this rewrites all requests to '/backend' to '/' ...
# # # ... before passing them to your backend-service
rewrite /backend.* / break;
# # #
proxy_pass http://back;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
}
I've adapted your docker-compose.yml for easy testing purposes:为了便于测试，我已经调整了您的docker-compose.yml ：
docker-compose.yml : docker-compose.yml ：
version: '3'
services:
backend:
image: nginx:alpine
hostname: backend
expose:
- 80
nginx:
image: nginx:alpine
ports:
- 8080:80
volumes:
- ./default.conf:/etc/nginx/conf.d/default.conf
default.conf : default.conf ：
upstream back {
# in docker-compose.yml file, (django+gunicorn) service name is `backend` and is listening on port 8000.
server backend:80;
}
server {
listen 80;
location /backend {
rewrite /backend.* / break;
proxy_pass http://back;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
}
docker-compose up : docker-compose up ：
╰─❯ docker-compose up
Starting test_backend_1 ... done
Starting test_nginx_1 ... done
Attaching to test_backend_1, test_nginx_1
backend_1 | 172.21.0.3 - - [03/Apr/2020:11:53:52 +0000] "GET / HTTP/1.0" 200 612 "-" "curl/7.64.1" "172.21.0.1"
nginx_1 | 172.21.0.1 - - [03/Apr/2020:11:53:52 +0000] "GET /backend HTTP/1.1" 200 612 "-" "curl/7.64.1" "-"
