基于 Nginx以及uwsgi 的 Django 环境搭建

基于Nginx以及uwsgi环境下,Django环境搭建,记录下来 !!!

安装 Django

先安装pip,再通过pip安装Django。

1.安装pip

cd /data;
mkdir tmp;
cd tmp;
wget https://bootstrap.pypa.io/get-pip.py;
python ./get-pip.py;

2.使用 PIP,安装 Django

pip install Django==1.11.7

安装 Mysql

1.安装并启动 mariadb

因为 CentOS 7 之后的版本都不在提供 Mysql 安装源,这里我们使用 mariadb 代替 mysql,依次执行下列命令

yum install mariadb mariadb-server -y
yum install MySQL-python -y
systemctl start mariadb

2.对 mariadb 进行初始化设置

执行下面命令,根据提示操作

设置新密码为 test

默认密码为空,直接回车即可

mysql_secure_installation

3.使用设置的密码登陆 mariadb

登陆 db,这里假设密码被设置为 test

mysql -uroot -ptest

4.创建一个数据库

create database mysite;

5.成功后,输入 exit 命令退出 db

exit

创建 Django 项目

1.创建 mysite 项目

在 /data/ 目录下,创建一个名为 mysite 的 Django 项目

cd /data/
django-admin startproject mysite

2.修改配置文件,与 Mysql 数据库相关联

备注:SECRET_KEY 配置项无需修改

编辑 /data/mysite/mysite/settings.py

示例代码:/data/mysite/mysite/settings.py

"""

3.创建 Django 数据库

cd /data/mysite
python manage.py migrate

4.启动 Django

python manage.py runserver

如果没有报错,就说明 Django 已经安装成功了,并且跟 Mysql 的连接正常

5.退出 Django

按 ctrl+c 退出 Django 服务

安装 Nginx

1.通过 yum 安装 Nginx

yum install nginx -y

2.启动 Nginx 服务

systemctl start nginx

访问你的服务器IP,可以看到 nginx 的欢迎界面

http://<您的 server IP 地址>/

安装 uwsgi

使用 yum 命令安装 uwsgi

yum install uwsgi uwsgi-plugin-python -y

让 Nginx,uwsgi,Django 协同工作[精华部分]

1.修改 Nginx 配置文件

编辑 /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 /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;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
            include uwsgi_params;
            uwsgi_pass 127.0.0.1:8000;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

# Settings for a TLS enabled server.
#
#    server {
#        listen       443 ssl http2 default_server;
#        listen       [::]:443 ssl http2 default_server;
#        server_name  _;
#        root         /usr/share/nginx/html;
#
#        ssl_certificate "/etc/pki/nginx/server.crt";
#        ssl_certificate_key "/etc/pki/nginx/private/server.key";
#        ssl_session_cache shared:SSL:1m;
#        ssl_session_timeout  10m;
#        ssl_ciphers HIGH:!aNULL:!MD5;
#        ssl_prefer_server_ciphers on;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        location / {
#        }
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#    }

}

2.重启 Nginx

/usr/sbin/nginx -s reload

3.创建 uwsgi 配置文件

在 /data/mysite 目录下创建 uwsgi.ini,参考下面的内容

示例代码:/data/mysite/uwsgi.ini

[uwsgi]
socket = 127.0.0.1:8000
chdir = /data/mysite
wsgi-file = mysite/wsgi.py
processes = 4
threads = 2
stats = 127.0.0.1:9191
uid = nobody
gid = nobody
master = true
harakiri = 30
daemonize = /data/mysite/uwsgi.log
plugins = python

4.启动 uwsgi

uwsgi uwsgi.ini
