Django+gunicorn+nginx項目部署

  經過gunicorn部署django項目,比使用uwsgi方式要簡單,具體操做以下:php

  步驟:html

 1. 安裝依賴python

yum install python3 yum install nginx (或者下載nginx包部署)
yum install gunicorn
pip install gevent   # 這個是gunicorn運行的一種模式
easy_install -U greenlet
easy_install -U eventlet

2. 檢查python/nginx安裝是否成功nginx

     a. 輸入python3,是否出現交互命令頁面django

      

     b. 啓動nginx, 瀏覽器訪問ip,出現weclome ngix瀏覽器

舉例:session

 啓動nginx:        ./nginxapp

2種方式驗證nginx是否啓動/安裝成功:tcp

     進程查看: ps -ef |grep nginx ide

     頁面訪問:  

     

 3. gunicorn 簡單使用

    按照上面的例子,當前目錄爲 /home/myapp, myapp中有一個包 gunicorn_app,gunicorn_app.py代碼以下:

 
 
def app(environ, start_response):
data = b"Hello, World!\n"
start_response("200 OK", [("Content-Type", "text/plain"),("Content-Length", str(len(data)))])
return iter([data])

咱們將要運行 test.py文件中的 app(固然名字由你決定,能夠是myapp,demo等等)

       gunicorn -w 2 gunicorn_app:app

    

 上圖展現了兩個很重要的信息:

   第一:啓動了兩個worker,這是經過"-w 2"指定(默認爲1)
   第二:worker的工做模型是sync(默認),後面會詳細介紹worker模型
 
 
 
Django項目部署
      項目結構:
      
    1. 上傳django項目到 /data/service目錄下,在 /data/service/Django_project目錄下 建立 static目錄
    2. 配置nginx文件, /usr/local/nginx/conf/nginx.conf
user root; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info;

#pid logs/nginx.pid;
 events { worker_connections 1024; } http { include 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 logs/access.log main;
 sendfile on; #tcp_nopush on;

    #keepalive_timeout 0;
    keepalive_timeout  65; #gzip on;
 server { listen 80; server_name 192.168.252.79; charset utf-8; #access_log logs/host.access.log main;
 location / { proxy_pass http://0.0.0.0:8001; # 這裏要配合啓動文件使用
 proxy_redirect off; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } location /static { alias /data/service/Django_project/static/; } #error_page 404 /404.html;

        # redirect server error pages to the static page /50x.html
        #         error_page   500 502 503 504  /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #         #location ~ \.php$ {
        # proxy_pass http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #         #location ~ \.php$ {
        # root html;
        # fastcgi_pass 127.0.0.1:9000;
        # fastcgi_index index.php;
        # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
        # include fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #         #location ~ /\.ht {
        # deny all;
        #}
 } # another virtual host using mix of IP-, name-, and port-based configuration
    #     #server {
    # listen 8000;
    # listen somename:8080;
    # server_name somename alias another.alias;

    # location / {
    # root html;
    # index index.html index.htm;
    # }
    #}


    # HTTPS server
    #     #server {
    # listen 443 ssl;
    # server_name localhost;

    # ssl_certificate cert.pem;
    # ssl_certificate_key cert.key;

    # ssl_session_cache shared:SSL:1m;
    # ssl_session_timeout 5m;

    # ssl_ciphers HIGH:!aNULL:!MD5;
    # ssl_prefer_server_ciphers on;

    # location / {
    # root html;
    # index index.html index.htm;
    # }
    #}
}

   3. 加載靜態文件,具體步驟以下:

        a. 修改settings.py中STATIC_ROOT爲你的static靜態文件的物理路徑,好比說我靜態文件存放在/data/service/Django_project/static中,首先建立Django目錄下的static文件夾,最後修改settings.py中STATIC_ROOT指向/data/service/Django_project/static.

       b. 運行python3 manage.py collectstatic命令,這將從Django資源包中複製必須的靜態文件到STATIC_ROOT指示的static文件夾中,這其中包括admin界面所必須的樣式表(style)、圖片(image)及腳本(js)等。

       c.修改nginx配置文件, nginx.conf中指向static目錄。

    4. Django根目錄建立 gunicorn.py文件,具體內容以下:

#gunicorn.py # coding:utf-8
import multiprocessing bind = '0.0.0.0:8001'      #綁定ip和端口號
backlog = 512                #監聽隊列
chdir = '/data/service/Django_project'  #gunicorn要切換到的目的工做目錄
timeout = 30      #超時
worker_class = 'gevent' #使用gevent模式,還能夠使用sync 模式,默認的是sync模式
 workers = multiprocessing.cpu_count() * 2 + 1    #進程數
threads = 2 #指定每一個進程開啓的線程數
loglevel = 'info' #日誌級別,這個日誌級別指的是錯誤日誌的級別,而訪問日誌的級別沒法設置
access_log_format = '%(t)s %(p)s %(h)s "%(r)s" %(s)s %(L)s %(b)s %(f)s" "%(a)s"'    #設置gunicorn訪問日誌格式,錯誤日誌沒法設置
 accesslog = "/home/gunicorn_log/gunicorn_access.log"      #訪問日誌文件
errorlog = "/home/gunicorn_log/gunicorn_error.log"        #錯誤日誌文件

 5. 能夠經過命令啓動服務,也能夠指向腳本啓動服務

      命令: /data/service/Django_project目錄下,執行  gunicorn Djanfo_project.wsgi -c gunicorn.py

      腳本: 在/data/service/Django_project目錄,建立 restrt.sh, 具體內容以下:   ./restart.sh start 

#!/bin/sh ## service name #項目的目錄
SERVICE_DIR=/data/service/Django_project #gunicorn的名字
SERVICE_NAME=gunicorn #gunicorn的配置文件名
SERVICE_CONF=gunicon.py #pid存放的位置
PID=gunicorn\.pid export PATH=$PATH:$HOME/bin:/usr/local/python3/bin cd $SERVICE_DIR start(){ nohup gunicorn app_basic_info.wsgi -c $SERVICE_DIR/gunicorn.py>/dev/null 2>&1 & echo $! > $SERVICE_DIR/$PID echo "*** start $SERVICE_NAME ***" } stop(){ kill `cat $SERVICE_DIR/$PID` rm -rf $SERVICE_DIR/$PID echo "*** stop $SERVICE_NAME ***" sleep 2 P_ID=`ps -ef | grep -w "$SERVICE_NAME" | grep -v "grep" | awk '{print $2}'` if [ "$P_ID" == "" ]; then echo "*** $SERVICE_NAME process not exists or stop success ***"
       else echo "*** $SERVICE_NAME process pid is:$P_ID ***" echo "*** begin kill $SERVICE_NAME process,kill is:$P_ID ***" kill -9 $P_ID fi } f_usage() { echo "USAGE: restart [options]" echo "OPTIONS:" echo " start" echo " stop " echo " restart" } case "$1" in

   "start") start ;; "stop") stop ;; "restart") stop sleep 2 start echo "*** restart $SERVICE_NAME ***" ;; *) f_usage ;; esac exit 0

   6. 瀏覽器訪問, http://localhost/admin/login
