利用docker部署django项目

一、前期准备

公司如果利用docker部署项目，项目根路径目录下，需要有以下三个文件：

1.requirements.txt

2.Dockerfile

3.uwsgi.ini

1.requirements.txt

django==1.11.11
pymysql

# 项目所有的依赖

2.Dockerfile

FROM python:3.6
MAINTAINER yessir
EXPOSE 8080
ADD ./requirements.txt /home/
RUN pip install -r /home/requirements.txt -i https://pypi.douban.com/simple/ 
RUN pip install uwsgi -i https://pypi.douban.com/simple/
VOLUME ["/home"]
WORKDIR /home/django_test
CMD ["uwsgi", "--ini", "/home/django_test/uwsgi.ini"] 

3.uwsgi.ini

[uwsgi]
# 配置和nginx连接的socket连接
socket=0.0.0.0:8080
# 也可以使用http
# http=0.0.0.0:8080
# 配置项目路径，项目的所在路径
chdir=/home/docker_test
# 配置wsgi接口模块文件路径
wsgi-file=docker_test/wsgi.py
# 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  # 以守护进程启动(后台启动的方式)，并将日志打印到指定文件

二、将项目提交到远程仓库

将项目提交到gitee仓库，在Linux系统中通过git clone拉取

git clone https://gitee.com/yessir_ye/django_test.git  # 第一次用git clone，后续只需用git pull即可

三、基于Dockerfile制作镜像

进入django_test文件夹下，基于该文件夹下的Dockerfile构建镜像

cd /opt/yessir/django_test/

docker build -t='django_1.11.11' .  
# 不要忽略了后面的点 .

四、基于制作的镜像运行容器

启动三个容器，分别为宿主机的8080、8081、8082全都映射到容器的8080端口，这样，访问宿主机的这三个端口，可以访问到该项目，

docker run -di --name=mydjango -v /root/yessir/django_test/:/home/django_test/ -p 8080:8080 django_1.11.11

docker run -di --name=mydjango1 -v /root/yessir/django_test/:/home/django_test/ -p 8081:8080 django_1.11.11

docker run -di --name=mydjango2 -v /root/yessir/django_test/:/home/django_test/ -p 8082:8080 django_1.11.11

五、配置Nginx转发

创建目录

mkdir -p /opt/nginx/conf /opt/nginx/html /opt/nginx/logs

新建Nginx配置文件

# 在nginx/conf文件夹下创建nginx.conf配置文件
vim /opt/nginx/conf/nginx.conf  

写入如下配置：

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    upstream node    {
        server    10.0.0.200:8080;
        server    10.0.0.200:8081;
        server    10.0.0.200:8082;
    }
    server {
        listen       80;
        server_name  localhost;
        location / {
          #proxy_pass http://101.133.225.166:8080;
          #负载均衡配置
          proxy_pass http://node;
        }  
    }
}

另起一个docker容器运行nginx

如果nginx转发没成功，可以查看下conf文件夹下是否有mime.types文件，没有的话需要去复制一份

    text/html                                        html htm shtml;
