Django需要Nginx幫助

Question

我正在嘗試將我的網站部署到aws ec2。它在python/django中，我想學習如何自己部署網站。我對aws的EBS有一些問題，所以首先我想知道如何手動執行此操作。 我決定爲此使用gunicorn和nginx。

我可以使用gunicorn在虛擬ENV運行的網站，我在/home/ec2-user/gunicorn_start.bash創建下面的腳本：

#!/bin/bash 

NAME="davidbiencom"         # Name of the 
application 
DJANGODIR=/home/ec2-user/davidbien    # Django project directory 
SOCKFILE=/home/ec2-user/virtual/run/gunicorn.sock 
USER=ec2-user          
GROUP=ec2-user          
NUM_WORKERS=3          
DJANGO_SETTINGS_MODULE=davidbiencom.settings    
DJANGO_WSGI_MODULE=davidbiencom.wsgi      

echo "Starting $NAME as `whoami`" 

# Activate the virtual environment 
cd $DJANGODIR 
source /home/ec2-user/virtual/bin/activate 
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE 
export PYTHONPATH=$DJANGODIR:$PYTHONPATH 
# Create the run directory if it doesn't exist 
RUNDIR=$(dirname $SOCKFILE) 
test -d $RUNDIR || mkdir -p $RUNDIR 

# Start your Django Unicorn 
# Programs meant to be run under supervisor should not daemonize themselves (do$ 
exec gunicorn ${DJANGO_WSGI_MODULE}:application \ 
--name $NAME \ 
--workers $NUM_WORKERS \ 
--user=$USER --group=$GROUP \ 
--bind=unix:$SOCKFILE \ 
--log-level=debug \ 
--log-file=- 

因爲沒有錯誤此運行良好，我相信。 接下來我安裝nginx並啓動服務。我確認它正在運行，因爲我收到歡迎頁面。接下來，我做到以下幾點：

1. 轉到/etc/nginx/nginx.conf並添加以下到http

   包括/etc/nginx/sites-enabled/*.conf;

然後我在/ etc/nginx/sites-available和sites-enabled中創建了兩個文件夾。 我創建一個文件davidbien.conf並輸入以下內（修訂版）：

upstream app_server { 
# fail_timeout=0 means we always retry an upstream even if it failed 
# to return a good HTTP response 

# for UNIX domain socket setups 
server unix:/home/ec2-user/virtual/run/gunicorn.sock fail_timeout=0; 

# for a TCP configuration 
# server 192.168.0.7:8000 fail_timeout=0; 
} 

server { 
listen 80; 
server_name 35.176.185.50; 

#Max upload size 
client_max_body_size 75M; # adjust to taste 

location /static/ { 
    root /home/ec2-user/davidbien/static; 
} 

location/{ 
    # checks for static file, if not found proxy to app 
    try_files $uri @proxy_to_app; 
} 

location @proxy_to_app { 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    # enable this if and only if you use HTTPS 
    # proxy_set_header X-Forwarded-Proto https; 
    proxy_set_header Host $http_host; 
    # we don't want nginx trying to do something clever with 
    # redirects, we set the Host: header above already. 
    proxy_redirect off; 
    proxy_pass http://app_server; 
    } 
} 

我保存這個文件並運行以下命令：

ln -s /etc/nginx/sites-available/davidbiencom.conf /etc/nginx/sites-enabled/davidbiencom.conf 

此步驟完成後我重啓nginx的，我當我輸入IP地址時，我得到502錯誤的網關錯誤。

這裏有什麼問題？ 謝謝。

Answer 1

你」重新告訴nginx它必須將請求轉發到127.0.0.1:3031，但是從我從腳本看到的啓動gunicorn的內容中，gunicorn被綁定到一個套接字上，如果你將在127.0.0.1:3031上啓動你的gunicorn worker，它應該工作
