flask+python+uwgsi+nginx+supervisor云服务器部署项目

配置环境

• 首先安装pip3 apt install python3-pip

• 安装虚拟环境 pip3 install virtualenv

• 创建存放网站的文件夹并进入
  

• 创建python虚拟环境virtualenv venv

  会生成一个venv文件夹
  

• 打开虚拟环境source ./venv/bin/activate
  
  这时在命令行最前面会出现(venv)可以通过deactivate 退出虚拟环境

• 然后把项目文件放入www文件夹，然后安装相应的库

  这里我把需要的库都放在requirement.txt中，直接用命令行安装全部库

  切记要在虚拟环境下安装
  

• （可选）这时可以将app.run()指定为host=‘0.0.0.0’ 然后python运行主文件 app.py 就可以在浏览器里访问该网站了

安装uwsgi

• 首先还是通过pip3安装uwsgi

• 然后在www目录下创建一个uwsgi.ini的配置文件

  写入如下内容

  
  [uwsgi]
    
  socket = 127.0.0.1:5000#或者可以填写内网ip
  chdir =/root/www/WebDemo/
  wsgi-file = app.py
  callable = app
  processes = 4
  threads = 2
  stats = 127.0.0.1:9191#同上 可以填写内网ip但是要保持一致
  

安装nginx

• apt install nginx

• 检查配置文件是否正确 nginx -t

  如果不出现successful 就重新安装下
  

• 然后用vim打开 /etc/nginx/sites-available/default

  修改里面的内容，

  ##
  # You should look at the following URL's in order to grasp a solid understanding
  # of Nginx configuration files in order to fully unleash the power of Nginx.
  # https://www.nginx.com/resources/wiki/start/
  # https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
  # https://wiki.debian.org/Nginx/DirectoryStructure
  #
  # In most cases, administrators will remove this file from sites-enabled/ and
  # leave it as reference inside of sites-available where it will continue to be
  # updated by the nginx packaging team.
  #
  # This file will automatically load configuration files provided by other
  # applications, such as Drupal or Wordpress. These applications will be made
  # available underneath a path with that package name, such as /drupal8.
  #
  # Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
  ##
  
  # Default server configuration
  #
  server {
          listen 80 ;#监听80端口
          server_name  107.191.41.24;#公网ip 通过这个ip在浏览器里访问
          # SSL configuration
          #
          # listen 443 ssl default_server;
          # listen [::]:443 ssl default_server;
          #
          # Note: You should disable gzip for SSL traffic.
          # See: https://bugs.debian.org/773332
          #
          # Read up on ssl_ciphers to ensure a secure configuration.
          # See: https://bugs.debian.org/765782
          #
          # Self signed certs generated by the ssl-cert package
          # Don't use them in a production server!
          #
          # include snippets/snakeoil.conf;
  
  
          # Add index.php to the list if you are using PHP
  		# 这里本来有一些其他的代码，可以删去，和这里保持一致
  
          location / {
                  # First attempt to serve request as file, then
                  # as directory, then fall back to displaying a 404.
                  include uwsgi_params;
                  uwsgi_pass  127.0.0.1:5000;#这里填写127.0.0.1或者是内网ip 必须和uwsgi.ini中写的ip一致
                  uwsgi_param UWSGI_PYTHON /root/www/venv/;#之前创建的虚拟环境目录
                  uwsgi_param UWSGI_CHDIR /root/www/WebDemo/;#项目的目录
                  uwsgi_param UWSGI_SCRIPT app:app;#第一个app是程序的入口，就是含有app.run的那个程序的名字 ，第二个app是主程序里的变量名，如果写的是xxx.run（），那xxx就是变量名
          }
  
  
          # pass PHP scripts to FastCGI server
          #
          #location ~ \.php$ {
          #       include snippets/fastcgi-php.conf;
          #
          #       # With php-fpm (or other unix sockets):
          #       fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
          #       # With php-cgi (or other tcp sockets):
          #       fastcgi_pass 127.0.0.1:9000;
          #}
  
          # deny access to .htaccess files, if Apache's document root
          # concurs with nginx's one
          #
          #location ~ /\.ht {
          #       deny all;
          #}
  }
  
  
  # Virtual Host configuration for example.com
  #
  # You can move that to a different file under sites-available/ and symlink that
  # to sites-enabled/ to enable it.
  #
  #server {
  #       listen 80;
  #       listen [::]:80;
  #
  #       server_name example.com;
  #
  #       root /var/www/example.com;
  #       index index.html;
  #
  #       location / {
  #               try_files $uri $uri/ =404;
  #       }
  #}
  
  

  保存，退出

• 接着可以用nginx -t检验下是否配置正确

  然后nginx -s reload重新加载nginx

  然后killall nginx关闭所有相关进程

  最后重新打开nginx

• 最后 在运行nginx情况下 执行uwsgi --ini uwsgi.ini
  
  然后就可以在浏览器里访问了
  

安装supervisor

• 通过apt-get install supervisor安装

• 在**/etc/supervisor/conf.d/**目录下新建一个.conf文件

  写入以下内容

  [program:uwsgi]#项目名称  
  command = /root/www/venv/bin/uwsgi --ini /root/www/uwsgi.ini #uwsgi在虚拟环境中的位置 和uwsgi.ini位置
  autostart = true
  autorestart = true
  user=root
  startretries = 5
  startsecs = 10
  stdout_logfile=/root/www/logs/uwsgi_supervisor.log#日志保存的位置
  [supervisord]
  nodaemon=true
  
  [supervisorctl]
  
  

• 重启supervisor

• 启动进程supervisorctl start uwsgi

  然后就可以访问网站了

• 如果要停止进程 supervisorctl start uwsgi

• 重启supervisor

• 启动进程supervisorctl start uwsgi

  然后就可以访问网站了

• 如果要停止进程 supervisorctl start uwsgi
