Docker搭建WEB环境之 Nginx & uWSGI

第一步安装Docker

PS：主机如果已经安装Docker，《第一步安装Docker》可跳过。

1.更新Ubuntu的apt源

sudo apt-get update

2.安装包允许apt通过HTTPS使用仓库

sudo dpkg --configure -a
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

3.添加Docker官方GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

4.设置Docker稳定版仓库

sudo add-apt-repository "deb [arch=arm64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

• [arch=arm64] 注意系统的平台选择

5.更新apt源

sudo apt-get update

6.安装最新版本Docekr CE（社区版）

sudo apt-get install docker-ce

7.查看安装Docker的版本

docker --version

8.检查Docker CE是否安装正确

sudo docker run hello-world

9.更新为国内源

sudo vim /etc/docker/daemon.json

写入以下文本

{
        "registry-mirrors": [
                "https://registry.docker-cn.com",
                "https://hub-mirror.c.163.com/"
        ]
}

10.重启docker

sudo systemctl restart docker

第二步新建容器web-v1，镜像centos8.4.2105

1.新建docker容器web-v1

sudo docker run -d -it -p 80:80 -p 8000:8000 --name web-v1 centos:8.4.2105

2.进入docker容器

sudo docker exec -it web-v1 bash

3.安装 yum-utils 工具

yum install yum-utils

出现错误：

执行以下操作

cd /etc/yum.repos.d/
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

• 重新安装

yum install yum-utils

第二步安装 Nginx

vi /etc/yum.repos.d/nginx.repo

写入文本

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

安装Nginx

yum install nginx

启动Nginx

nginx

访问http://192.168.157.129/

第三步安装Python虚拟环境

1.安装依赖

yum install -y gcc automake autoconf libtool make libffi-devel
yum install -y gcc gcc-c++

yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel xz-devel

yum install -y patch

yum install -y git wget unzip

2.安装pyenv

mkdir ~/.pyenv
//git下载
git clone git://github.com/pyenv/pyenv.git ~/.pyenv
//本地下载
wget -P  ~/.pyenv http://192.168.157.1/Share/pyenv-master.zip
unzip  ~/.pyenv/pyenv-master.zip -d  ~/.pyenv
mv ~/.pyenv/pyenv-master/* ~/.pyenv/

cd ~/.pyenv && src/configure && make -C src
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc  
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc  
echo 'eval "$(pyenv init -)"' >> ~/.bashrc  
exec $SHELL -l 

3.安装pyenv virtualenv

//git下载
git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv
//本地下载
wget -P  $(pyenv root)/plugins/pyenv-virtualenv http://192.168.157.1/Share/pyenv-virtualenv-master.zip
unzip  ~/.pyenv/plugins/pyenv-virtualenv/pyenv-virtualenv-master.zip -d  ~/.pyenv/plugins/pyenv-virtualenv
mv ~/.pyenv/plugins/pyenv-virtualenv/pyenv-virtualenv-master/* ~/.pyenv/plugins/pyenv-virtualenv/

echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile
exec "$SHELL"

4.创建虚拟环境

// 下载并安装python3.11.3
v=3.11.3;wget https://npm.taobao.org/mirrors/python/$v/Python-$v.tar.xz -P ~/.pyenv/cache/;pyenv install $v  

// 查看pyenv版本
pyenv versions

//新建test环境
pyenv virtualenv 3.11.3 test
pyenv activate test
pyenv deactivate test

5.虚拟环境test中安装Django

安装Django

pyenv activate test

pip install django
python -m django --version

/root/.pyenv/versions/test/bin/pip list

第四步Django创建项目

创建项目

cd /usr/share/nginx/html

django-admin startproject mysite

在setting.py里面需要添加ALLOWED_HOSTS=["*"]

vi /usr/share/nginx/html/mysite/mysite/settings.py

启动项目

python manage.py runserver 0.0.0.0:8000

报错

提示执行

python manage.py migrate

重启系统，访问http://192.168.157.129:8000/

python manage.py runserver 0.0.0.0:8000

第五步安装uwsgi

pyenv activate test

pip install uwsgi

//使用douban源安装
pip install uwsgi -i https://pypi.douban.com/simple/

配置uwsgi.ini文件

cd /usr/share/nginx/html/mysite/mysite
vi  /usr/share/nginx/html/mysite/mysite/uwsgi.ini

#添加配置选择
[uwsgi]
#配置和nginx连接的socket连接
socket = 127.0.0.1:8000

#配置项目路径，项目的所在目录
chdir = /usr/share/nginx/html/mysite

#配置wsgi接口模块文件路径
wsgi-file = mysite/wsgi.py

#配置启动的进程数
#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 =/usr/share/nginx/html/mysite/uwsgi.pid

#配置dump日志记录
daemonize = /var/log/mysite_uwsgi.log

# 指定python 环境
home = /root/.pyenv/versions/test/
post-buffering = 65536

max-requests = 10000
vacuum = true

#自动更新
#touch-reload = /usr/share/nginx/html/mysite/.git/index

后台启动uwsgi

/root/.pyenv/versions/test/bin/uwsgi -d -i /usr/share/nginx/html/mysite/mysite/uwsgi.ini

配置Nginx

cd /etc/nginx/conf.d/
vi /etc/nginx/conf.d/test.conf

server {
  listen       80;
  server_name  192.168.157.129;
  location / {
        #add_header 'Access-Control-Allow-Origin' '*';
        include      /etc/nginx/uwsgi_params;
        uwsgi_pass   127.0.0.1:8000;
        uwsgi_param UWSGI_PYHOME /root/.pyenv/versions/test/bin/python; # 指向虚拟环境目录
        uwsgi_param UWSGI_MAX_TEMP_FILE_SIZE  1000m;
        uwsgi_param UWSGI_MAX_TEMP_WRITE_SIZE  1000m;
        uwsgi_param UWSGI_SCRIPT app:app; # 指定启动程序
  }
  location /static/ {
    root /usr/share/nginx/html/mysite/mysite;
    break;
  }
}

重启Nginx

nginx -s reload
