Django需要Nginx帮助
问题描述:
我正在尝试将我的网站部署到aws ec2。它在python/django中,我想学习如何自己部署网站。我对aws的EBS有一些问题,所以首先我想知道如何手动执行此操作。 我决定为此使用gunicorn和nginx。Django需要Nginx帮助
我可以使用gunicorn在虚拟ENV运行的网站,我在/home/ec2-user/gunicorn_start.bash创建下面的脚本:
#!/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=-
因为没有错误此运行良好,我相信。 接下来我安装nginx并启动服务。我确认它正在运行,因为我收到欢迎页面。接下来,我做到以下几点:
-
转到/etc/nginx/nginx.conf并添加以下到http
包括/etc/nginx/sites-enabled/*.conf;
然后我在/ etc/nginx/sites-available和sites-enabled中创建了两个文件夹。 我创建一个文件davidbien.conf并输入以下内(修订版):
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;
}
}
我保存这个文件并运行以下命令:
ln -s /etc/nginx/sites-available/davidbiencom.conf /etc/nginx/sites-enabled/davidbiencom.conf
此步骤完成后我重启nginx的,我当我输入IP地址时,我得到502错误的网关错误。
这里有什么问题? 谢谢。

答
你”重新告诉nginx它必须将请求转发到127.0.0.1:3031,但是从我从脚本看到的启动gunicorn的内容中,gunicorn被绑定到一个套接字上,如果你将在127.0.0.1:3031上启动你的gunicorn worker,它应该工作
现在我想起来了,我不需要那部分,是吗?你认为它可以被删除? 删除该行后,我得到403禁止。 – davidb
我认为gunicorn将在端口8000上启动,如果你删除它 –
但不是nginx应该将所有来自端口80的流量都指向该应用程序吗? 我应该让它0.0.0.0:80然后呢?我看到一些教程没有这个设置。 – davidb
