1. 简单部署
1. sudo pip3 install gunicorn
2. cd 到django项目中 sudo python3 manage.py migrate
3.启动服务：sudo python3 manage.py runserver 0.0.0.0:8000
4. 使用gunicorn 来运行项目
注：项目名untitled
[root@qqc_os7 untitled]# gunicorn untitled.wsgi -b 0.0.0.0:8000
[2019-08-04 09:31:17 +0800] [16614] [INFO] Starting gunicorn 19.9.0
[2019-08-04 09:31:17 +0800] [16614] [INFO] Listening at: http://0.0.0.0:8000 (16614)
[2019-08-04 09:31:17 +0800] [16614] [INFO] Using worker: sync
[2019-08-04 09:31:17 +0800] [16617] [INFO] Booting worker with pid: 16617
5. 查看进程
[root@qqc_os7 untitled]# ps aux | grep 8000
root 15383 0.2 1.9 213440 19028 pts/3 S+ 19:27 0:00 /usr/local/python3/bin/python3.6 /usr/local/python3/bin/gunicorn untitled.wsgi -b 0.0.0.0:8000
root 15386 0.2 3.3 256572 33676 pts/3 S+ 19:27 0:00 /usr/local/python3/bin/python3.6 /usr/local/python3/bin/gunicorn untitled.wsgi -b 0.0.0.0:8000
root 15389 0.0 0.0 112676 992 pts/2 S+ 19:30 0:00 grep --color=auto 8000
6.杀死进程
[root@qqc_os7 untitled]# ps aux | grep 8000 | grep -v grep | awk ‘{print $2}‘ | xargs kill
查看开放的端口：firewall-cmd --list-ports
开启端口：firewall-cmd --zone=public --add-port=80/tcp --permanent (外网访问时开放端口)
查看网络：ping 10.0.0.130
访问：http://10.0.0.130:8000/index/
2. 添加环境变量
gunicorn目标位置：/usr/local/python3/lib/python3.6/site-packages (19.9.0)
[root@qqc_os7 /]# vim /etc/profile
末尾追加要加入环境变量的应用：
export PATH=/opt/mysql/bin:$PATH
export PATH=/opt/redis-3.2.10/src:$PATH:/usr/local/python3/bin
export RABBIT_HOME=/data/soft/rabbitmq_server-3.7.13
export PATH=$RABBIT_HOME/bin:$PATH
3. gunicorn常用配置
- Gunicorn“绿色独角兽”是一个被广泛使用的高性能的Python WSGI UNIX HTTP服务器
-c 指定一个配置文件(py文件)
-b 与指定的socket进行绑定
-D 以守护进程形式来运行Gunicorn进程，其实就是将这个服务放到后台去运行
-w 工作的进程数量 ；[root@qqc_os7 untitled]# gunicorn -w 2 untitled.wsgi -b 0.0.0.0:8000
-k 工作进程类型，sync（默认）, eventlet, gevent, or tornado, gthread, gaiohttp.
参考：https://www.jianshu.com/p/260f18aa5462
http://docs.gunicorn.org/en/latest/settings.html
- 配置文件(py文件,与django中的manage.py在同一目录)
# gunicorn_config.py
import logging
import logging.handlers
from logging.handlers import WatchedFileHandler
import os
import multiprocessing
bind = ‘10.0.0.130:8000‘ #绑定ip和端口号
backlog = 512 #监听队列
chdir = ‘/home/test/server/bin‘ #gunicorn要切换到的目的工作目录
timeout = 30 #超时
worker_class = ‘gevent‘ #使用gevent模式，还可以使用sync 模式，默认的是sync模式
workers = multiprocessing.cpu_count() * 2 + 1 #进程数
threads = 2 #指定每个进程开启的线程数
loglevel = ‘info‘ #日志级别，这个日志级别指的是错误日志的级别，而访问日志的级别无法设置
access_log_format = ‘%(t)s %(p)s %(h)s "%(r)s" %(s)s %(L)s %(b)s %(f)s" "%(a)s"‘
accesslog = "/home/test/server/log/gunicorn_access.log" #访问日志文件
errorlog = "/home/test/server/log/gunicorn_error.log" #错误日志文件
- 通过配置文件启动django服务：
[root@qqc_os7 untitled]# gunicorn untitled.wsgi -c gunicorn_config.py
- django项目目录结构
[root@qqc_os7 untitled]# tree
