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

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

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
