nginx + uwsgi 跑python應用

安裝nginx：

yum -y install nginx

編輯：vim /etc/nginx/nginx.conf

編輯系統配置文件：vim /etc/nginx/conf.d/XXX.conf 

map $http_upgrade $connection_upgrade {

}

把文件中的XXXXX換成你的域名，把XXX換成你的系統名稱

手動安裝uwsgi服務

1. 先決條件

• 安裝了python
• 安裝了python-devel
• 安裝了pip

1. 獲取uwsgi最新的源碼包： uwsgi-2.0.17.1.tar.gz
2. pip install uwsgi-2.0.17.1.tar.gz
3. 建立 /usr/lib/systemd/system/uwsgi.service 文件，內容爲

[Unit]

Description=uWSGI Emperor Service

After=syslog.target

 

[Service]

EnvironmentFile=-/etc/sysconfig/uwsgi

ExecStartPre=/bin/mkdir -p /run/uwsgi

ExecStartPre=/bin/chown uwsgi:uwsgi /run/uwsgi

ExecStart=/usr/bin/uwsgi  --ini /etc/uwsgi.ini

ExecReload=/bin/kill -HUP $MAINPID

KillSignal=SIGINT

Restart=always

Type=notify

StandardError=syslog

NotifyAccess=all

 

[Install]

WantedBy=multi-user.target

 

1. 新建 /etc/uwsgi.d/ 文件夾， /etc/uwsgi.ini 文件

   　　

[uwsgi]

uid = root

gid = root

socket = /var/run/uwsgi/uwsgi.socket

pidfile = /var/run/uwsgi/uwsgi.pid

emperor = /etc/uwsgi.d

#emperor-tyrant = true

master = true

autoload = true

log-date = true

logto = /var/log/uwsgi.log

1. XXX相關配置

1）    /etc/nginx/conf.d/XXX.conf

map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}

server {
listen *:80;
server_name *.XXXXX.com *.XXXXX.com.cn;
access_log /var/log/nginx/XXX.access.log main;
error_log /var/log/nginx/XXX.error.log;
root /app/XXX/XXX_web/dist;
index index.html;

add_header Access-Control-Allow-Origin http://XXX.XXXXX.com;
add_header Access-Control-Allow-Headers Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,X-Data-Type,X-Auth-Token,X-Requested-With;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS,HEAD,PUT,DELETE;
add_header Access-Control-Allow-Credentials true;

location / {
root /app/XXX/XXX_web/dist;
index index.html;
try_files $uri $uri/ /index.html last;
}

location ^~ /api {
uwsgi_pass XXX-admin;
uwsgi_send_timeout 600;
uwsgi_connect_timeout 600;
uwsgi_read_timeout 600;
include uwsgi_params;
uwsgi_param UWSGI_PYHOME /app/XXX/venv;
uwsgi_param UWSGI_CHDIR /app/XXX;
uwsgi_param UWSGI_SCRIPT XXX:app;
uwsgi_param SCRIPT_NAME "";
}

location /socket.io {
proxy_pass http://socketio_nodes/socket.io;
proxy_http_version 1.1;
proxy_buffering off;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";

}

}

server {
listen 80;
server_name _;
access_log /var/log/nginx/nginx.log main;
error_log /var/log/nginx/nginx.err;
return 400;
}

2）    /etc/uwsgi.d/XXX.ini

[uwsgi]
chdir = /app/XXX/
wsgi-file = /app/XXX/XXX.py
home = /app/XXX/venv

http-websockets = true
virtualenv = /app/XXX/venv
callable = app
vacuum = true

uwsgi-socket = 0.0.0.0:8001
socket = /run/uwsgi/XXX.sock

buffer-size = 65535

master = false

enable-threads = true

processes = 4
threads = 2

thunder-lock = true

plugins = python

lazy-apps = true

3）    /etc/uwsgi.d/XXX-socket.ini

[uwsgi]
gevent=1000
gevent-monkey-patch=true
http=:5555
http=:5556
http=:5557
http=:5558
http-websockets=true
master=true
chdir=/app/XXX/
virtualenv=/app/XXX/venv
buffer-size=65535
thunder-lock=true
vacuum=true
wsgi-file=XXX_SOCKET.py
callable=app

 

本應用起了websocket，若是沒有的能夠去除相關配置
