【保姆级】Python项目部署到Linux生产环境（uwsgi+python+flask+nginx服务 ...

1.安装python

我这里是3.9.5版本
安装依靠：

1. yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y

复制代码

根据本身的需要下载对应的python版本：

1. cd /usr/local
2. wget https://www.python.org/ftp/python/3.9.5/Python-3.9.5.tgz

复制代码

 解压 > 编译 > 安装

1. tar -xvf Python-3.9.5.tgz
2. cd /usr/local/Python-3.9.5
3. ./configure
4. make all
5. make install

复制代码

Python解释器配置清华源：

1. pip3.9 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple/

复制代码

2.假造环境配置

1）安装 virtualenv

1. pip3.9 install virtualenv

复制代码

2）创建假造环境（一样寻常是一个项目一个假造环境）

1. mkdir home/python_item/envs
2. cd /home/python_item/envs/
3. virtualenv /home/python_item/envs/tender --python=python3.9

复制代码

3）激活假造环境

1. source  /home/python_item/envs/tender/bin/activate

复制代码

4）安装项目依靠

1. cd /home/python_item/tender_project #进入项目目录
3. pip3.9 install flask
4. pip3.9 install lxml
5. pip3.9 install pymysql
6. pip3.9 install requests

复制代码

3、uwsgi安装

1）安装uwsgi

1. 激活虚拟环境，在虚拟环境中安装
2. source  /home/python_item/envs/tender/bin/activate
3. pip install uwsgi

复制代码

2）基于uwsgi配置文件的方式运行flask项目

1. [uwsgi]
2.     socket = 127.0.0.1:8001  
3.     chdir = /home/python_item/tender_project
4.     wsgi-file = main.py
5.     callable = app
6.     processes = 1
7.     virtualenv = /home/python_item/envs/tender/

复制代码

3）启动项目

1. uwsgi --ini tender_test.ini

复制代码

报错：

1. (tender) [root@node1 tender_project]# uwsgi --ini tender_test.ini
2. [uWSGI] getting INI configuration from tender_test.ini

解决：
urllib3版本不兼容，卸载重装

1. pip3.9 uninstall urllib3
3. pip3.9 install urllib3==1.22

复制代码

重启即可

1. uwsgi --ini tender_test.ini

复制代码

nginx

安装：Linux安装Nginx

4.访问成功 

5.编写脚本快速重启/制止

reboot.sh

1. #! /usr/bin/env bash
2. echo -e "======================wsgi process======================"
4. ps -ef|grep tender_test.ini |grep -v grep
6. sleep 0.5
8. echo -e "======================going to close ======================"
10. ps -ef | grep tender_test.ini | grep -v grep | awk '{print $2}' | xargs kill -9
12. sleep 0.5
14. echo -e "======================check if the kill action is correct ======================"
16. /home/python_item/envs/tender/bin/uwsgi --ini tender_test.ini & >/dev/null
18. echo -e "======================started... ======================"
20. sleep 1
22. ps -ef | grep tender_test.ini |grep -v grep

复制代码

 stop.sh

1. echo -e "======================wsgi process======================"
3. ps -ef|grep tender_test.ini |grep -v grep
5. sleep 0.5
7. echo -e "======================going to close ======================"
9. ps -ef  |grep tender_test.ini | grep -v grep | awk '{print $2}' | xargs kill -9
11. sleep 0.5

复制代码

在项目目录下实验重启或制止，脚本放在下面，根据本身的现实环境举行修改即可
更新权限

1. chmod 775 reboot.sh
3. chmod 775 stop.sh

复制代码

启动！

1. ./reboot.sh
3. ./stop.sh
