ubuntu NGINX uwsgi https 部署Django 遇到的问题

搞了3天终于把Django成功部署到Ubuntu，记录一下；

引用来自泡泡茶壶：

Ubuntu下的Nginx + Uwsgi + Django项目部署详细流程

前提说明：

Django作为小程序的后端，因小程序的请求到后端的都是https请求，所以Django必须支持https请求

写在前面：

部署Django项目前，先用Django自带服务器运行一下看有没有问题，再部署；否则可能项目本身有问题，却以为是部署不正确导致的

运行命令：python manage.py runserver .....

各种配置：

1、nginx支持https请求

1）项目对象的nginx.conf配置

# the upstream component nginx needs to connect to
upstream django {# unix:///home/breavo/PyWorkSpace/mysite_code_shuffle/config/eshop.sockserver xx.xx.xx.xx:8002; # xx.xx.xx.xx是服务器的ip，若是腾讯云服务器，则是服务器外部ip，这里的ip和端口是和uwsgi通信的方式，所以和uwsgi.ini配置文件中一致
}# configuration of the server
server {# the port your site will be served onlisten 90 ssl; # 监听端口可以是任何端口，但不要和已使用端口冲突# listen 8003;# the domain name it will serve forserver_name  indoor.crazymonkey.ml; # 这里可以是域名也可以是本机ip，同上面的xx.xx.xx.xxcharset     utf-8;# max upload sizeclient_max_body_size 75M;   # adjust to taste# ssl configurationssl on; # 打开了ssl验证，支持https请求ssl_certificate /root/hewenjuan/Indoor_Localization/2446810_www.preciselocation.top.pem; # ssl证书放的位置ssl_certificate_key /root/hewenjuan/Indoor_Localization/2446810_www.preciselocation.top.key; # 使用绝对路径肯定没错啦# Django medialocation /media  {alias /root/hewenjuan/Indoor_Localization/media; # your Django project's media files - amend as required，有图片等，}location /static {# alias /path/to/your/mysite/static; # your Django project's static files - amend as requiredalias /root/hewenjuan/Indoor_Localization/static; # 静态文件位置，Django项目admin静态文件}# Finally, send all non-media requests to the Django server.location / {uwsgi_pass  django; # 这个就是引用了上面的upstream django配置了# include     /home/breavo/PyWorkSpace/mysite_code_shuffle/config/uwsgi_params; # the uwsgi_params file you installedinclude /etc/nginx/uwsgi_params;}
}

　　说明：用nginx -t命令查看上面nginx文件的正确性

2）项目对应的uwsgi.ini配置

# mysite_uwsgi.ini file
[uwsgi]
socket =  xx.xx.xx.xx:8002 # 腾讯云内部ip，端口和nginx.conf配置的Django部分相同
# Django-related settings
# the base directory (full path)
chdir           = /root/hewenjuan/Indoor_Localization  # Django项目所在目录
# Django's wsgi file
module          = Indoor_Localization.wsgi #
# module =  config/hello.py:application
wsgi_file = Indoor_Localization/wsgi.py # Django项目wsgi.py所在位置，相对于上面的chdir目录
# wsgi_file =  /root/hewenjuan/Indoor_Localization/config/hello.py:application
# the virtualenv (full path)
virtualenv = /root/.pyenv/versions/indoorLocation/bin/python3.6  # python虚拟环境绝对位置
# home            = /root/.pyenv
home            = /root/.pyenv/versions/indoorLocation# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 10
# the socket (use the full path to be safe
# socket          = /root/hewenjuan/Indoor_Localization/Indoor_Localization.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = truestats           = %(chdir)/config/uwsgi.status           pidfile         = %(chdir)/config/uwsgi.pid
# daemonize = %(chdir)/config/uwsgi.log # 开启该字段，uwsgi会在后台运行，日志保存在该文件中，若没有开启该字段，则在前台运行，日志显示在界面上（调试用方便）
# pidfile = %(chdir)/config/uwsgi.pid
#plugins =  /root/.pyenv/versions/indoorLocation/bin/python3.6

　　3）每次修改了Django项目文件代码，都需要重启uwsgi和nginx，所以自己写了个启动文件start.sh

killall -9 uwsgi  # 关闭所有uwsgi进程，有时候没有关掉上次的uwsgi进程，启动新的会报错等问题
killall -9 uwsgi  # 额，有时候关闭一次会出现没关掉的情况
uwsgi --ini mysite_uwsgi.ini # 启动mysite_uwsgi.ini文件，即启动uwsgi进程
/etc/init.d/nginx restart # 重启nginx进程

　　说明：启动start.sh命令：sh start.sh

2、uwsgi支持https请求

1）uwsgi.ini配置

# mysite_uwsgi.ini file
[uwsgi]# 2446810_www.preciselocation.top.pem,2446810_www.preciselocation.top.key是ssl证书
https = xx.xx.xx.xx:443,2446810_www.preciselocation.top.pem,2446810_www.preciselocation.top.key # xx.xx.xx.xx是腾讯云内部ip
# Django-related settings
# the base directory (full path)
chdir           = /root/hewenjuan/Indoor_Localization
# Django's wsgi file
module          = Indoor_Localization.wsgi
# module =  config/hello.py:application
wsgi_file = Indoor_Localization/wsgi.py
# wsgi_file =  /root/hewenjuan/Indoor_Localization/config/hello.py:application
# the virtualenv (full path)
virtualenv = /root/.pyenv/versions/indoorLocation/bin/python3.6
# home            = /root/.pyenv
home            = /root/.pyenv/versions/indoorLocation# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 10
# the socket (use the full path to be safe
# socket          = /root/hewenjuan/Indoor_Localization/Indoor_Localization.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = truestats           = %(chdir)/config/uwsgi.status           pidfile         = %(chdir)/config/uwsgi.pid
# daemonize = %(chdir)/config/uwsgi.log
# pidfile = %(chdir)/config/uwsgi.pid
#plugins =  /root/.pyenv/versions/indoorLocation/bin/python3.6

遇到的问题：

1、每次退出账号重新登录都会提示，pyenv 不存在了

原因：

方法：命令行输入：source ~/.bashrc；即执行.bashrc文件中的语句（包含了pyenv初始化语句）

2、nginx权限问题：django admin后台样式不显示，查看nginx错误日志（位置：/var/log/nginx/error.log），显示权限拒绝Permission denied

原因：Django项目下的static文件执行权限不够

方法：打开文件/etc/nginx/nginx.conf，修改 user www-data为user root（root：你目前登录的账号名称，也可能是Ubuntu等其他）

参考qingspace：https://www.cnblogs.com/qingspace/p/6838747.html

3、unavailable modifier requested

原因：没有激活python虚拟环境

方法：输入命令：pyenv activate xx，激活xx环境，xx是你项目所在的python虚拟环境

4、安装项目依赖包：pip install -r requirements.txt，遇到一个问题：安装不成功，界面没有显示不成功

出现下面显示的Successfully ...才表示安装成功

原因：requirements.txt文件中有win_xx的安装包，即有python接入window系统所使用的安装包，类似了win32等，啥除掉即可；

因为有可能写代码使用的是window系统，部署的时候放在了Linux系统

解决方法：删除win32等针对window系统的安装包
