环境配置

OS: CentOS7
Python:Python3.5+
Python模块：

mod.txt

Django==1.11.11
django-redis==4.11.0
Jinja2==2.11.1
Pillow==7.1.1
PyMySQL==0.9.3

安装步骤

1. 安装Xtrabackup

wget https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.4.9/binary/redhat/7/x86_64/percona-xtrabackup-24-2.4.9-1.el7.x86_64.rpm
yum install -y percona-xtrabackup-24-2.4.9-1.el7.x86_64.rpm

2. 配置MySQL(安装略)

create database Xtra charset=utf8;
create user Xtra identified by '123456';
grant all on Xtra.* to 'Xtra'@'%';
flush privileges;

3. 安装Redis

yum -y install redis

4. 开始搭建XtrawithDjango项目

(1) 准备项目目录拉取代码

mkdir Xtra
mkdir /tmp/xtra_test/
cd Xtra/
yum -y install git
git clone "https://github.com/wuyangdevops/XtrawithDjango.git"
cd XtrawithDjango/

(2) 安装虚拟环境（略）迁移数据表

mkvirtualenv -p python3 Xtra
pip3 install -r mod.txt
python manage.py makemigrations
python manage.py migrate

(3) 测试Django能否正常运行

python manage.py runserver 0.0.0.0:80

5. 生产环境搭建XtrawithDjango项目

(1) 安装supervisor

yum -y install python3-devel
yum install epel-release
yum install -y supervisor
systemctl enable supervisord
systemctl start supervisord

(2) 安装Nginx

yum -y install nginx
systemctl enable nginx
systemctl start nginx

(3) 配置Nginx

请修改/etc/nginx/nginx.conf配置文件中如下内容

user root;
...
        location / {
                include uwsgi_params;
                uwsgi_pass 127.0.0.1:8000;
        }
        location /static {
         alias /root/Xtra/XtrawithDjango/Xtra/Xtra/static;
       }

然后重启Nginx

systemctl restart nginx

(4) 配置uwsgi托管Django

pip3 install uwsgi

该工程中wsgi.ini配置信息如下：

"""
WSGI config for WebXtra project.
It exposes the WSGI callable as a module-level variable named ``application``.
For more information on this file, see
https://docs.djangoproject.com/en/1.11/howto/deployment/wsgi/
"""
[uwsgi]
socket=127.0.0.1:8000
chdir=/root/Xtra/XtrawithDjango/Xtra
wsgi-file=Xtra/wsgi.py
processes=4
threads=2
master=True
pidfile=uwsgi.pid
daemonize=uwsgi.log
virtualenv=/root/.virtualenvs/Xtra/

使用supervisord来管理uwsgi进程
将Xtra.ini配置文件放入/etc/supervisord.d/目录
重载supervisord

supervisorctl reload
