1.安装python
我这里是3.9.5版本
安装依赖：
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y根据自己的需要下载对应的python版本：
cd local
wget https://www.python.org/ftp/python/3.9.5/Python-3.9.5.tgz解压 > 编译 > 安装
tar -xvf Python-3.9.5.tgz
cd Python-3.9.5.tgz
./configure
make all
make install
Python解释器配置清华源：
pip3.9 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple/2.虚拟环境配置
1）安装 virtualenv
pip3.9 install virtualenv2）创建虚拟环境（一般是一个项目一个虚拟环境）
mkdir home/python_item/envs
cd /home/python_item/envs/
virtualenv /home/python_item/envs/tender --python=python3.9
3）激活虚拟环境
source /home/python_item/envs/tender/bin/activate4）安装项目依赖
cd /home/python_item/tender_project #进入项目目录
pip3.9 install flask
pip3.9 install lxml
pip3.9 install pymysql
pip3.9 install requests3、uwsgi安装
1）安装uwsgi
激活虚拟环境，在虚拟环境中安装
source /home/python_item/envs/tender/bin/activate
pip install uwsgi2）基于uwsgi配置文件的方式运行flask项目
[uwsgi]
socket = 127.0.0.1:8001
chdir = /home/python_item/tender_project
wsgi-file = main.py
callable = app
processes = 1
virtualenv = /home/python_item/envs/tender/ 3）启动项目
uwsgi --ini tender_test.ini报错：
(tender) [root@node1 tender_project]# uwsgi --ini tender_test.ini

解决：
urllib3版本不兼容，卸载重装
pip3.9 uninstall urllib3
pip3.9 install urllib3==1.22重启即可
uwsgi --ini tender_test.ininginx
安装：Linux安装Nginx
配置：
upstream flask {
server 127.0.0.1:8001 weight=1;
}
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
location /tenderTest {
uwsgi_pass flask;
include /usr/local/nginx/conf/uwsgi_params;
# index index.html index.htm;
}
location /test/ {
uwsgi_pass 127.0.0.1:8002;
include /usr/local/nginx/conf/uwsgi_params;
# index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#

location = /50x.html {

}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80

# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}4.访问成功
5.编写脚本快速重启/停止
在项目目录下执行重启或停止，脚本放在下面，根据自己的实际情况进行修改即可
./reboot.sh
./stop.shreboot.sh
#! /usr/bin/env bash
