mysql + Python3.5.2 + Django + Uwsgi + Nginx实现生产环境

官方文档:http://uwsgi-docs-zh.readthedocs.io/zh_CN/latest/tutorials/Django_and_nginx.html
前面已经安装好mysql数据库，Python3.5.2, pip, django1.8.5, nginx(前面安装脚本需要删除：--without-http_uwsgi_module)

一
安装uwsgi:
pip install uwsgi
uwsgi --version
2.0.15

测试uwsgi：
cat test.py
# test.py
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return [b"Hello World"] # python3
#return ["Hello World"] # python2

运行：
uwsgi --http :8000 --wsgi-file test.py
浏览器访问服务器IP:8000，返回Hello World，测试正常。

用uwsgi 启动django测试：
uwsgi --http :8001 --chdir /root/blogproject/ --module blogproject.wsgi
浏览器访问服务器IP:8001,返回网页内容，测试正常。

把参数写到配置文件里:
[uwsgi]
# 项目目录
chdir=/root/blogproject/
# 指定项目的application
module=blogproject.wsgi
# 进程个数
workers=5
pidfile=/root/blogproject/uwsgi.pid
# 指定IP端口
http= :8080
# 指定静态文件
static-map=/static=/root/blogproject/static
# 启动uwsgi的用户名和用户组
# uid=root
# gid=root
# 启用主进程
master=true
# 自动移除unix Socket和pid文件当服务停止的时候
vacuum=true
# 序列化接受的内容，如果可能的话
thunder-lock=true
# 启用线程
enable-threads=true
# 设置自中断时间
harakiri=30
# 设置缓冲
post-buffering=4096
# 设置日志目录
daemonize=/root/blogproject/script/uwsgi.log
# 指定sock的文件路径
socket=/root/blogproject/script/uwsgi.sock
#socket = 127.0.0.1:8001
#设置sock文件权限
#chmod-socket = 664

启动和关闭进程
uwsgi --ini uwsgi.ini # 启动uwsgi配置
[uWSGI] getting INI configuration from uwsgi.ini
[uwsgi-static] added mapping for /static => /root/blogproject/static # 启动成功，可以执行ps -ef |grep uwsgi 查看相关进程

uwsgi --stop uwsgi.pid # 关闭uwsgi
uwsgi --reload uwsgi.pid #重新加载配置

二
Nginx配置：
upstream django {
# server 127.0.0.1:8001;
server unix:///root/blogproject/script/uwsgi.sock;

}
server {
listen 80;
server_name www.victory168.top victory168.top;
access_log /var/log/nginx/access.log; # Nginx log file
error_log /var/log/nginx/error.log; # Nginx error log file
charset utf-8; # Nginx coding
gzip on; # gzip
gzip_types text/plain application/x-javascript text/css text/javascript application/x-httpd-php application/json text/json image/jpeg image/gif image/png application/octet-stream; # gzip type

error_page 404 /404.html; #404 file
error_page 500 502 503 504 /50x.html; # 50x file

# set uwsgi path
location / {
include uwsgi_params; # import Nginx module with uWSGI communication
# set uwsgi sock path file
# uwsgi_pass unix:/root/blogproject/script/uwsgi.sock;
uwsgi_pass django;
}

# set static path
location /static/ {
alias /root/blogproject/static/;
# index index.html index.htm;
}
}

nginx -t # 检查nginx语法问题

三
django静态文件收集

1.setting.py设置
DEBUG = False
STATIC_ROOT = os.path.join(BASE_DIR, 'statics')

2. 执行collectstatic命令：
python manage.py collectstatic

3.启动Nginx和uwsgi程序的用户应一致

遇到问题查看Nginx error.log和uwsgi.log，

4.导出本地开发环境安装的依赖模块：
pip freeze > requirements.txt

5.检查服务器端安装的依赖模块：
[root@nagios_client2 blogproject]# pip list
Django (2.0)
Markdown (2.6.11)
pip (9.0.1)
Pygments (2.2.0)
PyMySQL (0.8.0)
pytz (2017.3)
setuptools (20.10.1)
uWSGI (2.0.15)
