项目上线全程

Posted 2020-11-27 djflask

1.买服务器,掏钱吧

2.连上服务器,22端口改一下,默认密码改复杂一点.其他的随意, 再adduser 一个个人账户, 没事别用root

给它加上sudo权限

usermod -a -G sudo wqk
# 再确认一下
groups wqk
切换到wqk
su wqk

3.安装虚拟环境,隔离项目

可以用pip或者apt安装,这里我们选择pip

a. 查看pip版本
          查看pip版本: pip -V
        查看pip3版本: pip3 -V
    b. 安装pip(如果存在则不需要安装)
        安装pip3: apt install python3-pip    
         安装pip2: apt install python-pip    
    c. 更新pip
          更新pip (如果pip版本高于9.0则不需要更新): 
              更新pip3: pip3 install --upgrade pip
             更新pip: pip install --upgrade pip
 
         注意: 更新后如出现以下错误（这是pip 10.0.0版本的BUG）：
            Traceback (most recent call last): 
            File “/usr/bin/pip”, line 9, in 
            from pip import main

            解决方法：修改对应pip文件中的代码(pip和pip3类似)
                  例如更新pip时报错则需要修改 /usr/bin/pip 文件中的代码，
                使用: sudo vim /usr/bin/pip 打开pip文件
                将：          
                    from pip import main
                    if __name__ == ‘__main__‘:
                        sys.exit(main())
                改成：
                    from pip import __main__
                    if __name__ == ‘__main__‘:
                        sys.exit(__main__._main())

        
    d. pip命令
          pip install xxx:安装xxx依赖包
        pip list:查看所有依赖包
        pip freeze:查看新安装的包
        pip uninstall xxx ：卸载xxx包

1.3, virtualenv和virtualenvwrapper 的安装和使用
   【请使用普通用户】 
    a. 安装虚拟环境
          sudo apt update
          sudo pip3 install virtualenv virtualenvwrapper
        sudo pip install virtualenv virtualenvwrapper
        sudo apt install virtualenv virtualenvwrapeer
        
        
        mkvirtualenv env3 -p /usr/bin/python3
          安装后如果不能使用虚拟环境命令，则需要配置环境变量
            1, 进入家目录: cd ~
            2, 使用vim打开.bashrc, 定位到最后:shift+g，并添加以下2行代码(注意修改自己Ubuntu的用户名)
                    export WORKON_HOME=/home/自己Ubuntu的用户名/.virtualenvs
                    source /usr/local/bin/virtualenvwrapper.sh
            3, 在家目录创建.virtualenvs目录: mkdir .virtualenvs
            4, 加载修改后的设置，使之生效：source .bashrc
            （如果找不到virtualenvwrapper.sh,
             则将路径改成/usr/local/bin/virtualenvwrapper.sh
             然后重试 ）
      b. 创建虚拟环境: 
          mkvirtualenv env  
          mkvirtualenv env2 -p /usr/bin/python3  (指定python路径)
      c. 退出虚拟环境
          deactivate 
    d. 进入虚拟环境: 
          workon 虚拟环境名称

 4.虚拟环境里面安装库文件,  一般从开发环境里面pip -freeze > environment.txt直接拿出来  然后pip install -r environment.txt 进行安装

5.安装nginx,配置uwsgi,配置文件如下

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;
    
    limit_conn_zone $binary_remote_addr zone=one:100m;

    ##
    # SSL Settings
    ##

    server {
    listen 80 default_server;
    # listen [::]:8000 default_server;
    # limit_rate 12048k;
    root /var/www/OnlinePay;


    server_name _;
    location /static {
            alias /var/www/OnlinePay/static;
        }

    location / {
        include /etc/nginx/uwsgi_params;
        uwsgi_pass 127.0.0.1:8888;

    location /down {
        limit_conn   one  1;  #限制每个IP只能发起一个并发连接
        limit_rate 9000k;
        alias /var/www/ipa/;
    }
}
    ##
    # Virtual Host Configs

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

    server {

    root /var/www/OnlinePay;

    location /static {
