# Centos django+uwsgi+nginx部署 #

![在这里插入图片描述][20200713215238767.png_pic_center]

## 安装Python ##

*CentOS 7 Linux发行版默认包含Python 2。但是，Python 2将于2020年1月1日停产。尽管一些遗留应用程序可能由于各种原因需要访问Python 2，但是启动Python 3中的新项目至关重要。*

### 通过软件管理包Yum ###

1.  更新环境
    
        $ yum update -y
    
     *  **-y**：安装包的时候会询问y/n,这个参数是所有询问默认y，下边不再提醒，在终端输入以上命令时，直接下载安装，不再要求确认。
    
    在7.7之前的CentOS 7版本中，CentOS基本存储库没有提供Python 3软件包。从CentOS 7.7开始，Python 3可在基本软件包存储库中使用！
2.  安装Python3
    
        $ yum install -y python3

### 源码安装 ###

#### 环境依赖 ####

$ yum install gcc openssl-devel bzip2-devel libffi-devel -y

#### 下载Python ####

# 下载
    $ wget https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tgz
    # 解压
    $ tar -xzf Python-3.8.3.tgz

#### 安装Python3 ####

进入目录

$ cd Python-3.8.3/

编译

$ ./configure --enable-optimizations

安装

$ make && make install

## uwsgi ##

### 安装uwsgi ###

*由于uWSGI由EPEL提供，因此无需使用进行安装`pip`。*

$ yum -y install uwsgi uwsgi-plugin-python3

### 配置uwsgi ###

在django项目`manage.py`同级目录下，创建`uwsgi.ini`文件。

[uwsgi]
    chdir=/home/wj/Project/data_analysis
    module=data_analysis.wsgi:application
    socket=:8000
    processes=5
    threads=2
    master=True
    pidfile=uwsgi.pid
    vacuum=True
    max-requests=5000
    daemonize=uwsgi.log
    env DJANGO_SETTINGS_MODULE=data_analysis.settings
    home=/home/wj/Envs/django

注意：如果后期运行时出现以下这种错误，只需在`uwsgi.ini`文件里添加`plugins = python36`（python36是Python版本）

-- unavailable modifier requested: 0 --

### 运行uwsgi ###

$ uwsgi --ini uwsgi.ini

*会生成指定自己指定名称的`.log`文件和`.pid`文件*

### 停止uwsgi ###

$ uwsgi --stop uwsgi.pid

## nginx ##

### 安装 ###

$ yum install -y nginx

### 配置nginx ###

#### 查看nginx配置文件位置 ####

$ nginx -t
    nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
    nginx: configuration file /etc/nginx/nginx.conf test is successful

查看配置文件/etc/nginx/nginx.conf

$ cat /etc/nginx/nginx.conf
    # For more information on configuration, see:
    # * Official English Documentation: http://nginx.org/en/docs/
    # * Official Russian Documentation: http://nginx.org/ru/docs/
    
    user nginx;
    worker_processes auto;
    error_log /var/log/nginx/error.log;
    pid /var/run/nginx.pid;
    
    # Load dynamic modules. See /usr/share/nginx/README.dynamic.
    include /usr/share/nginx/modules/*.conf;
    
    events { 
        worker_connections  1024;
    }
    
    
    http { 
        log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                          '$status $body_bytes_sent "$http_referer" '
                          '"$http_user_agent" "$http_x_forwarded_for"';
    
        access_log  /var/log/nginx/access.log  main;
    
        sendfile            on;
        tcp_nopush          on;
        tcp_nodelay         on;
        keepalive_timeout   65;
        types_hash_max_size 2048;
    
        include             /etc/nginx/mime.types;
        default_type        application/octet-stream;
    
        # Load modular configuration files from the /etc/nginx/conf.d directory.
        # See http://nginx.org/en/docs/ngx_core_module.html#include
        # for more information.
        include /etc/nginx/conf.d/*.conf;
    }

我们只需关注`include /etc/nginx/conf.d/*.conf;`

进入`/etc/nginx/conf.d/`，在此目录下创建以`.conf`结尾的文件。

#### 创建配置文件 ####

$ vim django.conf
    # mysite_nginx.conf
    
    upstream django { 
        server 127.0.0.1:8001; # 服务器的套接字
    }
    
    server { 
        # 监听的端口号
        listen      8000;
        # 编码
        charset     utf-8;
    
        # Finally, send all non-media requests to the Django server.
        location / { 
            uwsgi_pass  django;
            include     uwsgi_params; # 可下载，也可自己创建文件。
        }
    }

uwsgi\_params：https://github.com/nginx/nginx/blob/master/conf/uwsgi\_params

uwsgi_param  QUERY_STRING       $query_string;
    uwsgi_param  REQUEST_METHOD     $request_method;
    uwsgi_param  CONTENT_TYPE       $content_type;
    uwsgi_param  CONTENT_LENGTH     $content_length;
    
    uwsgi_param  REQUEST_URI        $request_uri;
    uwsgi_param  PATH_INFO          $document_uri;
    uwsgi_param  DOCUMENT_ROOT      $document_root;
    uwsgi_param  SERVER_PROTOCOL    $server_protocol;
    uwsgi_param  REQUEST_SCHEME     $scheme;
    uwsgi_param  HTTPS              $https if_not_empty;
    
    uwsgi_param  REMOTE_ADDR        $remote_addr;
    uwsgi_param  REMOTE_PORT        $remote_port;
    uwsgi_param  SERVER_PORT        $server_port;
    uwsgi_param  SERVER_NAME        $server_name;

### 检查nginx配置 ###

$ nginx -t
    nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
    nginx: configuration file /etc/nginx/nginx.conf test is successful

### 启动nginx ###

$ service nginx restart
