运用Nginx代理和UWSGI将Flask项目部署在Linux中详细步骤

nginx:
安装可以参照的路径:
http://nginx.org/en/linux_packages.html#Ubuntu

启动Nginx

    nginx     [ -c  configpath]   默认配置目录：/etc/nginx/nginx.conf

查看进程：

    ps -ef |grep nginx

控制Nginx

    nginx -s xxxstop         快速关闭quit        优雅的关闭reload        重新加载配置

nginx的配置：/etc/nginx/nginx.conf ----》 nginx默认的启动文件

cp一个启动文件到项目目录中

配置代码内容：

user root; -----》要与master process名称保持相同

运行要用绝对路径
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
}

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;
server_name localhost;

#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
root /home/liu/flask0923; -----》项目目录

location /static { -----》配置静态文件
alias /home/liu/flask0923/static;
}

location / { ------》 python相关的文件对接uwsgi服务器
include /etc/nginx/uwsgi_params;
uwsgi_pass localhost:8000; -----》端口号要注意与uwsgi.ini的保持一致
}

}
}

启动： nginx -c +绝对路径

如果出现日志log文件错误命令前加上 sudo！！！！！！！

nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)
2019/09/25 19:57:51 [warn] 4096#4096: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:2
2019/09/25 19:57:51 [notice] 4096#4096: signal process started
2019/09/25 19:57:51 [alert] 4096#4096: kill(3886, 3) failed (1: Operation not permitted)

nginx -c /home/liu/flask0923/nginx.conf

nginx -s quit

nginx -s reload

配置： uwsgi

进入虚拟环境 workon中

pip install uwsgi

在项目下：创建uwsgi.ini 文件 !!!!!!!!踩坑用错会无法监听80端口

内容:
[uwsgi]
# 使用nginx连接时 使用
# socket = 0.0.0.0:8000

# 直接作为web服务器使用
http = 0.0.0.0:8000

# 配置工程目录
chdir = /home/running/Documents/day46_blog
wsgi-file = manage.py
# router
callable = app

# 配置项目的wsgi目录。相对于工程目录 django
# chdir = /root/shop/aixianfeng
# wsgi-file = aixianfeng/wsgi.py

#配置进程，线程信息
processes = 4

threads = 10

enable-threads = True

master = True

pidfile = uwsgi.pid

daemonize = uwsgi.log

启动: uwsgi --ini /home/running/Documents/day46_blog/uwsgi.ini

停止: uwsgi --stop uwsgi.pid

Nginx.conf
