CentOS7下部署Django项目_centos7部署django

服务器

 服务器的基本配置

        随便购买一台服务器,使用CentOS系统并记住记住自己的公网IP

        去安全组放行端口

        

去Gitee新建一个代码仓库

Git

下载git,用来同步代码 下载地址:Git - Downloading Package (git-scm.com)

设置好安装路径一路下一步就行

安装好之后 桌面右键 Git Bash Here

全局配置 进入刚刚在Gitee新建的仓库

git config --global user.name "用户名"
git config --global user.email "邮箱"

 在Git输入从Gitee全局设置的两行代码

然后进入项目地址的文件夹 右键 Git Bash Here

初始化

git init

 配置远程地址

git remote add origin https://gitee.com/zzwxxw/xxxxx.git

本地版本提交并提交至代码仓库

git add .
git commit -m '提交说明...'
git push origin master

但是每次提交会输入Gitee的账号密码十分不方便,可以使用SSH

在Git里输入

ssh-keygen -t rsa

查看ssh公钥并复制下来

cat ~/.ssh/id_rsa.pub

在Gitee设置找到SSH公钥,并粘贴进去,这样每次推送就不会要重复输入账号密码

在项目中创建一个 .gitignore的文件，在里面写上文件名或文件夹，可以git忽略一些文件，不要进行版本控制。

#   For a library or package, you might want to ignore these files since the code is

# pipenv
#   According to pypa/pipenv#598, it is recommended to include Pipfile.lock in version control.
#   However, in case of collaboration, if having platform-specific dependencies or dependencies
#   having no cross-platform support, pipenv may install dependencies that don't work, or not
#   install all needed dependencies.
#Pipfile.lock
 
# poetry
#   Similar to Pipfile.lock, it is generally recommended to include poetry.lock in version control.
#   This is especially recommended for binary packages to ensure reproducibility, and is more
#   commonly ignored for libraries.
#   https://python-poetry.org/docs/basic-usage/#commit-your-poetrylock-file-to-version-control
#poetry.lock
 
# pdm
#   Similar to Pipfile.lock, it is generally recommended to include pdm.lock in version control.
#pdm.lock
#   pdm stores project-wide configurations in .pdm.toml, but it is recommended to not include it
#   in version control.

服务器安装git

yum install git -y

 进入项目克隆或拉取代码

基于用户名和密码，需要输入用户和密码
    git clone https://gitee.com/wupeiqi/xxxxx.git
    
基于用户名和密码，直接集成用户和密码
    git clone https://用户名:密码@gitee.com/wupeiqi/xxxxx.git
 
基于秘钥：
    >>>ssh-keygen -t rsa
    >>>cat ~/.ssh/id_rsa.pub
    >>>拷贝公钥到代码仓库
    >>>git clone git@gitee.com:wupeiqi/xxxxx.git

Mysql 

在CentOS安装Mysql

CentOS 安装 MySQL - 腾讯云开发者社区-腾讯云 (tencent.com)

Python

安装Python3.9

yum install gcc -y

安装Python3相关依赖

yum install zlib zlib-devel -y
yum install bzip2 bzip2-devel  -y
yum install ncurses ncurses-devel  -y
yum install readline readline-devel  -y
yum install openssl openssl-devel  -y
yum install xz lzma xz-devel  -y
yum install sqlite sqlite-devel  -y
yum install gdbm gdbm-devel  -y
yum install tk tk-devel  -y
yum install mysql-devel -y
yum install python-devel -y
yum install libffi-devel -y

cd /data/
wget https://www.python.org/ftp/python/3.9.5/Python-3.9.5.tgz

注意：如果没有wget，则先安装 yum install wget -y

tar -xvf Python-3.9.5.tgz

 进入目录并编译安装

cd Python-3.9.5
./configure
make all
make install

 配置豆瓣源（腾讯云服务器，默认腾讯源）

pip3.9 config set global.index-url https://pypi.douban.com/simple/

虚拟环境 

安装虚拟环境

pip3.9 install virtualenv

创建虚拟环境目录并创建虚拟环境 

mkdir /envs
virtualenv /envs/nb --python=python3.9

安装项目依赖的pip包 

source /envs/nb/bin/activate
pip install flask
pip install pymysql
pip install dbutils

uwsgi 

激活虚拟环境并安装uwsgi 

source /envs/nb/bin/activate
pip install uwsgi

在本地项目根目录下创建 nb_uwsgi.ini

;添加配置选择
[uwsgi]
;配置和nginx连接的socket连接
socket=127.0.0.1:8997
;配置项目路径，项目的所在目录
chdir=/data/www/test/
;配置wsgi接口模块文件路径,也就是wsgi.py这个文件所在的目录名
wsgi-file=day01/wsgi.py
;虚拟环境地址
virtualenv = /envs/nb/
;#配置启动的进程数
processes=4
;#配置每个进程的线程数
threads=2
;#配置启动管理主进程
master=True
#配置存放主进程的进程号文件
pidfile=uwsgi.pid
;配置dump日志记录
daemonize=uwsgi.log`

把本地文件上传至代码仓库

git push 仓库地址

 服务器更新代码

git pull 仓库地址

nginx

利用nginx做反向代理和处理静态文件

yum install nginx -y

修改nginx.conf配置文件： /etc/nginx/nginx.conf 

events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    server {
        listen 80;
        server_name  127.0.0.1:80; #改为自己的域名，没域名修改为127.0.0.1:80
        charset utf-8;
        location / {
           include uwsgi_params;
           uwsgi_pass 127.0.0.1:8997;  #端口要和uwsgi里配置的一样
           uwsgi_param UWSGI_SCRIPT day01.wsgi;  #wsgi.py所在的目录名+.wsgi
           uwsgi_param UWSGI_CHDIR /data/www/test/; #项目路径
           
        }
        location /static/ {
        alias /data/www/test/app01/static/; #静态资源路径
        }
    }
}

启动

接下来就需要启动uwsgi和nginx

uwsgi

uwsgi --ini  nb_uwsgi.ini

 nginx

# 启动
systemctl start nginx
systemctl stop nginx
 
# 开机启动
systemctl enable nginx

启动完之后就可以访问了 

Shell脚本

但是每次启动停止都比较麻烦,可以写个脚本

reboot.sh

#!/usr/bin/env bash
 
echo -e "\033[34m--------------------wsgi process--------------------\033[0m"
 
ps -ef|grep nb_uwsgi.ini | grep -v grep
 
sleep 0.5
 
echo -e '\n--------------------going to close--------------------'
 
ps -ef |grep nb_uwsgi.ini | grep -v grep | awk '{print $2}' | xargs kill -9
 
sleep 0.5
 
echo -e '\n----------check if the kill action is correct----------'
 
/envs/nb/bin/uwsgi  --ini nb_uwsgi.ini &  >/dev/null
 
echo -e '\n\033[42;1m----------------------started...----------------------\033[0m'
sleep 1
 
ps -ef |grep nb_uwsgi.ini | grep -v grep

stop.sh

#!/usr/bin/env bash
 
echo -e "\033[34m--------------------wsgi process--------------------\033[0m"
 
ps -ef |grep nb_uwsgi.ini | grep -v grep
 
sleep 0.5
 
echo -e '\n--------------------going to close--------------------'
 
ps -ef |grep nb_uwsgi.ini | grep -v grep | awk '{print $2}' | xargs kill -9
 
sleep 0.5

 执行需要给权限

chmod 755 reboot.sh
chmod 755 stop.sh
