I have a Django web application that uses Gunicorn and runs good locally, but when I deploy app on EC2, I see that Gunicorn is failing: $ gunicorn_django -b 127.0.0.1:8000 --settings=myapp.settings.dev --debug --log-level info 2012-09-16 17:39:24 [28333] [INFO] Starting gunicorn 0.14.6 2012-09-16 17:39:24 [28333] [INFO] Listening at: http://127.0.0.1:8000 (28333) 2012-09-16 17:39:24 [28333] [INFO] Using worker: sync 2012-09-16 17:39:24 [28336] [INFO] Booting worker with pid: 28336 2012-09-16 17:39:24 [28336] [INFO] Worker exiting (pid: 28336) 2012-09-16 17:39:24 [28333] [INFO] Shutting down:

Flask session not persistent across requests in Flask app with Gunicorn on Heroku

邮差的信 提交于 2019-11-30 15:30:19
I'm running a Flask application with Gunicorn as a web server. The whole project is deployed to Heroku. Procfile web: gunicorn app:app --log-file=- Flask sessions are implemented server side, only a session id is stored in the flask.session object. Whenever I'm trying to do a login, I get logged in correctly at first, but then get redirected to the starting site (which should be the user site). LoginController.py def login(form) : User.session.set(User.getByLogin(form)) if User.session.exists() : return redirect(Urls.home) return redirect(Urls.login) The log shows that User.session.exists()

使用 Nginx + Gunicorn 的方式将 django 应用部署到自己的服务器

部署前准备 为了部署我们的博客,需要满足以下条件: Django项目需在Pipenv虚拟环境下建立 配置服务器 服务器环境为 CentOS 7(64 位) 创建一个超级用户 连接到远程服务器了,如果是一台全新服务器的话,通常我们是以 root 用户登录的。在 root 下部署代码不够安全,最好是建一个新用户(如果你已经以非 root 用户登录的话可以跳过这一步)。下面的一些列命令将创建一个拥有超级权限的新用户(把 zerobit 替换成你自己想要的用户名): # 在 root 用户下运行这条命令创建一个新用户,zerobit 是用户名 # 选择一个你喜欢的用户名,不一定非得和我的相同 root@server:~# adduser zerobit ​ # 为新用户设置密码 # 注意在输密码的时候不会有字符显示,不要以为键盘坏了,正常输入即可 root@server:~# passwd zerobit ​ # 把新创建的用户加入超级权限组 root@server:~# usermod -aG wheel zerobit ​ # 切换到创建的新用户 root@server:~# su - zerobit ​ # 切换成功,@符号前面已经是新用户名而不是 root 了 zerobit@server:$ 如果是新服务器的话,最好先更新一下系统,避免因为版本太旧而给后面安装软件带来麻烦

Troubleshooting Site Slowness on a Nginx + Gunicorn + Django Stack

问题 Issue I Was Having I was having an issue where some sites were taking a long time to load (By "long time" I mean up to 16 seconds). Sometimes they might timeout entirely, which generated a Nginx 504 error. Usually, when a site timed out I could reload the site again and it would load quickly. The site that I was having issues with gets a very low amount of traffic. I'm testing the site by loading the Django admin index page in order to try and eliminate any slowness that could be caused

Getting Gunicorn to run on port 80

情到浓时终转凉″ 提交于 2019-11-30 12:08:33
I built an API with flask. My app does not have any static assets hence there's no reason for me to use nginx. I wish to run gunicorn on port 80. I have a "deploy script": mkdir .log 2> /dev/null DEBUG=0 gunicorn -b 0.0.0.0:80 backend:app --access-logfile .log/access.log --error-logfile .log/general.log I wish to run gunicorn on port 80 with authbind . I followed this guide here. Note that I am able to run authbind python -m SimpleHTTPServer 80 When I try to run authbind ./deployment.run 80 , I am seeing the following error: 2013-04-25 15:32:55 [24006] [ERROR] Can't connect to ('0.0.0.0', 80)

Is there a way to log python print statements in gunicorn?

纵然是瞬间 提交于 2019-11-30 11:08:37
With my Procfile like this: web: gunicorn app:app \ --bind "$HOST:$PORT" \ --debug --error-logfile "-" \ --enable-stdio-inheritance \ --reload \ --log-level "debug" is it in any way possible to get python print statements to be logged to stdout / bash? I am using the bottle framework here as well, if that affects anything. It turns out the print statements were actually getting through, but with delay. The gunicorn docs for --enable-stdio-inheritance note to set the PYTHONUNBUFFERED , which I thought I had, but it seems with wrong syntax. I solved it using a .env file with my foreman setup to

gunicorn+nginx配置方法

十年热恋 提交于 2019-11-30 10:08:53
对于gunicorn+nginx的配置,理解他们之间的关系很重要,以及最后如何确认配置结果是正确的也很重要 nginx 配置文件: 修改这个配置文件有3个用处: 假设服务器本身的Ip是A称为ip-A,而我用gunicorn启动flask时写的ip是127.0.0.1,用ip-B表示 1.当我在浏览器输入http://ip-A:端口(nginx的端口) 时,nginx会把访问地址指向http://ip-B:端口(gunicorn启动的端口) 所以我们页面看到的内容实际是gunicorn启的flask的根页面, 即视图函数中app.route('/')装饰器所装饰的函数所返回页面的内容 那么这种映身关系在nginx.conf配置文件中如何配置呢? 主要就是对proxy_pass进行配置 参数说明: listen是所需要监听的端口 server_name是需要绑定的域名, 暂时没有域名时,请使用ip location / 是当访问到根下的时候,将所有请求转发到127.0.0.1:8000,本文使转发到gunicorn启动的django应用上,中间配置的是需要转发的内容,基本上述内容可以满足大多需求,如需特殊需求请自行查看nginx官方文档 location /static/ 配置了静态文件所在的路径,静态文件由nginx处理,动态转发到django,如不配置会出现站点引用的所有js

Sharing static global data among processes in a Gunicorn / Flask app

蓝咒 提交于 2019-11-30 08:06:14
问题 I have a Flask app running under Gunicorn, using the sync worker type with 20 worker processes. The app reads a lot of data on startup, which takes time and uses memory. Worse, each process loads its own copy, which causes it to take even longer and take 20X the memory. The data is static and doesn't change. I'd like to load it once and have all 20 workers share it. If I use the preload_app setting, it only loads in one thread, and initially only takes 1X memory, but then seems to baloon to

python web 部署:nginx + gunicorn + supervisor + flask

一世执手 提交于 2019-11-30 08:04:46
python web 部署 web开发中,各种语言争奇斗艳,web的部署方面,却没有太多的方式。简单而已,大概都是 nginx 做前端代理,中间 webservice 调用程序脚本。大概方式: nginx + webservice + script nginx 不用多说,一个高性能的web服务器。通常用来在前端做反向代理服务器。所谓正向与反向(reverse),只是英文说法翻译。代理服务,简而言之,一个请求经过代理服务器从局域网发出,然后到达互联网上服务器,这个过程的代理为正向代理。如果一个请求,从互联网过来,先进入代理服务器,再由代理服务器转发给局域网的目标服务器,这个时候,代理服务器为反向代理(相对正向而言)。 正向代理:{ 客户端 ---》 代理服务器 } ---》 服务器 反向代理:客户端 ---》 { 代理服务器 ---》 服务器 } {} 表示局域网 nginx既可以做正向,也可以做反向。 webservice 的方式同样也有很多方式。常见的有 FastCGI , WSGI 等。我们采用 gunicorn 为 wsgi容器。python为服务器script,采用 flask 框架。同时采用supervisor管理服务器进程。也就是最终的部署方式为: nginx + gunicorn + flask ++ supervisor 创建一个项目 mkdir myproject
