1 python安装

官网地址：https://www.python.org/

本次下载的python安装包地址：https://www.python.org/ftp/python/3.8.16/Python-3.8.16.tgz

解压下载的python压缩包

[root@localhost software]# tar -zxvf Python-3.8.16.tgz

# 进到解压后的目录执行configure
[root@localhost Python-3.8.16]# ./configure

#安装GCC
[root@localhost Python-3.8.16]# yum install gcc -y

# 安装下面python暗转需要的依赖包
yum install zlib zlib-devel openssl openssl-devel
yum install glib2-devel openssl-devel pcre-devel bzip2-devel gzip-devel
yum install libffi-devel -y
yum install zlib zlib-devel
yum install libjpeg libjpeg-devel
yum install freetype freetype-devel

# 编译
[root@localhost Python-3.8.16]# make

# 安装，安装完成后输入python3查看安装成功的版本信息
[root@localhost Python-3.8.16]# make install


# 命令行输出python看到的还是系统自带默认的python2.7.5版本
[root@localhost Python-3.8.16]# python

#经过上面的创建之后，yum指令会出错，将第一行修改为#!/usr/bin/python2
[root@localhost bin]# yumFile "/usr/bin/yum", line 30except KeyboardInterrupt, e:^

编辑文件vim /usr/bin/yum，将首行修改为#!/usr/bin/python2。

2 Django项目部署

# 执行下面指令安装  python-devel和 mysql-devel
yum install mysql-devel
yum install python-devel

#安装uwsgi
pip install uwsgi

编写一个django.ini文件，文件内容如下

[uwsgi]
socket =0.0.0.0:9090
master =1
processes =1
pidfile = /var/run/django_one.pid
#日志路径
daemonize = /var/log/uwsgi/django_one.log
#模块
module = django_one.wsgi:application
#项目目录
chdir =/home/dream21th/code/django_one
listen = 100
buffer-size =32768
max-requests = 200

[root@localhost code]# ll
总用量 4
-rw-rw-r--.  1 dream21th dream21th 255 8月   1 10:24 django.ini
drwxr-xr-x. 10 root      root      184 7月  31 17:09 django_one

#启动项目
[root@localhost code]# uwsgi --ini django.ini

在nginx中配置下面信息，就可以访问Django中的接口

       location / {uwsgi_pass 127.0.0.1:9090;uwsgi_param UWSGI_SCRIPT django_one.wsgi;include uwsgi_params;}
