專案配置

• 建立一個簡單的flask專案

from flask import Flask, jsonify

app = Flask(__name__)


@app.route("/index")
def index(
 
):
    return jsonify("hello world!")


if __name__ == '__main__':
    app.run(host="0.0.0.0", port=8000)

• 專案結構
  tree -L 1 # 顯示第一層目錄
  [[email protected] datas]# tree -L 1

[[email protected] datas]# tree -L 1 
.
├── app.py   # flask專案
├── html     # 儲存nginx靜態檔案地址
├── mypro    # 專案虛擬環境
 

├── nginx.conf  # nginx配置檔案
├── nginx.conf.bak  # 備份
├── nohup.out  
├── __pycache__
├── uwsgi.ini  # uwsgi啟動檔案
└── uwsgi.pid

3 directories, 6 files

配置uwsgi

• 編寫uwsgi.ini

[uwsgi]
socket=172.23.72.65:8000  # 使用nginx啟動使用socket。單獨通過uwsgi啟動用 http:172.23.72.65:8000
chdir = /tmp/datas
virtualenv =/tmp/datas/mypro
wsgi-file =
 
 /tmp/datas/app.py
callable = app
#plugins = python
master = true
vacuum = true
chmod-socket = 664
processes = 3
daemonize = /var/log/mypro/uwsgi.log
pidfile = /tmp/datas/uwsgi.pid

• 通過uwsgi.ini啟動flask專案

uwsgi --ini uwsgi.ini

配置nginx

• 編輯nginx.conf檔案

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    server {
        listen 80;  # 監聽80埠
        server_name 172.23.72.65;  # flask服務地址

        location / {
            uwsgi_pass 172.23.72.65:8000;  # flask服務地址+埠
            include uwsgi_params;  # 預設uwsgi_params
            root /var/nginx/html;  # nginx根目錄
            index index.html index.html;
        }

        error_page 500 502 503 504 /50x.html;

        location = /50x.html {
            root /var/nginx/html;
        }
    }

}

docker配置nginx

• 拉取nginx映象

docker pull nginx

• 啟動nginx

# 啟動容器
docker run --name nginx-uwsgi -p 80:80 -d nginx
# 獲取容器id
docker ps

• 將專案中nginx.conf配置檔案替換掉容器中預設的nginx.conf配置檔案

docker cp /tmp/datas/nginx.conf 7c9fcf3ece3e:/etc/nginx/nginx.conf  # 7c9fcf3ece3e: 容器id

• 將當前容器儲存為映象

docker commit 7c9fcf3ece3e nginx-test  # 生成新nginx映象nginx-test

• 啟動新映象nginx-test，重新啟動uwsgi

# 啟動nginx
docker run --name nginx-test -v /tmp/datas/html/:/var/nginx/html -p 8915:80 -d nginx-test
# 殺死uwsgi
pkill -9 uwsgi
# 重新啟動uwsgi
uwsgi --ini uwsgi.ini
