在centos7上部署dajngo（nginx+uWSGI）

以下的前提环境是django通过python runserver 0.0.0.0:80外网输入IP可正常访问
此文总结自此文，十分感谢作者分享
uWSGI

安装uWSGI
不知为何 pip install uwsgi 后uwsgi 总是无法找到命令，只好下载源码安装
wget https://pypi.python.org/pypi/uWSGI/
tar -zxvf uwsgi-2.0.15.tar.gz
cd uwsgi-2.0.15
make
然后将其加入连接
ln -s /root/uwsgi-2.0.15/uwsgi /usr/bin/uwsgi
测试：uwsgi –http 0.0.0.0:80 –wsgi-file text.py
text.py

def application(env, start_response):
start_response(‘200 OK’, [(‘Content-Type’,’text/html’)])
return [b”Hello World”]

uwsgi常用命令：uwsgi –ini /root/web/uwsgi.ini #以此配置运行uwsgi
lsof -i :80 查看80端口被那些进程占用（yum install lsof）
kill -9 pid 杀死pid号的进程

nginx

yum install epel-release
yum install nginx

nginx 服务器重启命令，关闭
nginx -s reload ：修改配置后重新加载生效
nginx -s reopen ：重新打开日志文件
nginx -t -c /path/to/nginx.conf 测试nginx配置文件是否正确

关闭nginx：
nginx -s stop :快速停止
nginx -s quit ：完整有序的停止nginx
其他的停止nginx 方式：
ps -ef | grep nginx
kill -QUIT 主进程号 ：从容停止Nginx
kill -TERM 主进程号 ：快速停止Nginx
pkill -9 nginx ：强制停止Nginx

启动nginx:
nginx -c /path/to/nginx.conf
平滑重启nginx：
kill -HUP 主进程号

综合：在安装好uwsgi和nginx后我需要在Django的APP同级目录下添加2个文件，

1.uwsgi.ini

使用时需要把注释删掉（在阿里云控制台安全组入方向8000端口要放开）

[uwsgi]
socket = 127.0.0.1:8000 #此地址要和下面的nginx的配置文件web.conf中一致
chdir=/root/web #dajngo的project
module=web.wsgi #指明Django的wsgi的地址
master = true
processes=2
threads=2
max-requests=2000
chmod-socket=664
vacuum=true
daemonize = /root/web/uwsgi.log #日志存放位置

2.web.conf

3.启动uwsgi

uwsgi uwsgi.ini

4.启动nginx

nginx -c /path/to/nginx.conf

5.访问IP地址验证是否成功。
