• 基于Centos搭建Django 环境搭建


    CentOS 7.2 64 位操作系统

    安装 Django

    先安装 PIP,再通过 PIP 安装 Django

    安装 PIP

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

    使用 PIP,安装 Django

    pip install Django==1.11.7

    安装 Mysql

    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

    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

    使用设置的密码登陆 mariadb

    登陆 db,这里假设密码被设置为 root

    mysql -uroot -ptest

    创建一个数据库

    create database mysite;

    成功后,输入 exit 命令退出 db

    exit

    创建 Django 项目

    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

    修改配置文件,与 Mysql 数据库相关联(SECRET_KEY 配置项无需修改)

    示例代码:/data/mysite/mysite/settings.py

      1 """
      2 Django settings for mysite project.

    创建 Django 数据库

    cd /data/mysite
    python manage.py migrate

    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

    按 ctrl+c 退出 Django 服务

    安装 Nginx

    通过 yum 安装 Nginx

    yum install nginx -y

    启动 Nginx 服务

    systemctl start nginx

    访问下面的链接,可以看到 nginx 的欢迎界面 http://118.89.65.22/

    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

    修改 Nginx 配置文件

    示例代码:/etc/nginx/nginx.conf

    88 #        }
    89 #    }
    90 }

    重启 Nginx

    /usr/sbin/nginx -s reload

    创建 uwsgi 配置文件

    请在 /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

    启动 uwsgi

    uwsgi uwsgi.ini

    测试
