flask项目在Linux上部署

有两种部署方式：

1. flask run的方式
2. uwsgi 部署

flask run的方式：

目录下必须有程序入口wsgi.py 或者是 run.py

cd myapp-admin
source venv/bin/activate
flask run -h 0.0.0.0 -p 8888
# -h 0.0.0.0 web访问
#-p 8888 端口号
# nohup flask run -h 0.0.0.0 -p 8888  2>&1 &. 后台运行

uwsgi 部署的方式

创建一个app.ini文件

# app.ini
[env]
env=dev

[uwsgi]
master = true
# 以下几个配置使用uWSGI可以动态根据负载扩展使用的进程数
# set cheaper algorithm to use, if not set default will be used
cheaper-algo = spare
chdir = /home/xxx
# minimum number of workers to keep at all times
cheaper = 2
# number of workers to spawn at startup
cheaper-initial = 2
# maximum number of workers that can be spawned
workers = 4
# how many workers should be spawned at a time
cheaper-step = 1
# 直接启动web服务   要借助nginx 用socket socket = 0.0.0.0:13001 
http = 0.0.0.0:13001 
chmod-socket = 666
#在退出uwsgi环境后，清空环境变量
vacuum = true
die-on-term = true
callable = app
module = xxx.wsgi
logger = file:///home/xxx/.log
buffer-size = 32768
http-timeout = 1200
# 后台启动
daemonize = yes
wsgi-file=/home/xxx/wsgi.py
pidfile=/home/xxx/xxx.pid

命令行：

cd myapp-admin
source venv/bin/activate
uwsgi --ini app.ini # 启动

启动成功之后会有一个.pid文件

# 重启：
uwsgi --reload xxx.pid
# 停止：
uwsgi --stop xxx.pid
