Flask部署

 

安装必备环境

配置

 

 

安装必备环境

nginx，uwsgi

 

 

配置

 

uwsgi

启动配置文件

# 配置 /home/liuwei/mycode/py/FlaskDemo/uwsgi.ini

[uwsgi]
#application‘s base folder，配置为项目的根目录
base = /home/liuwei/mycode/py/FlaskDemo

#python module to import
# 这个app的值指的就是flask应用下的app.py
app = app
module = %(app)

# 项目依赖的环境目录
home = /home/liuwei/mycode/py/envs/flaskdemoenv
pythonpath = %(base)

#socket file‘s location，生成nginx依赖的文件，其中%n表示当前文件的名字
socket = %(base)/%n.sock

#permissions for the socket file
chmod-socket = 666

#the variable that holds a flask application inside the module imported at line #6
callable = app

#location of log files
logto = /var/log/uwsgi/%n.log

 

日志输出文件

# 创建上面配置logto的文件夹，以及降权限
sudo mkdir -p /var/log/uwsgi
sudo chown -R liuwei:liuwei /var/log/uwsgi

 

启动

# cd  /home/liuwei/mycode/py/FlaskDemo
uwsgi --ini uwsgi.ini

# 当启动后，就会在项目目录下生成uwsgi.sock文件，这个文件被nginx依赖，所以你要先启动uwsgi

#日志需要注意参数：
    # current working directory
    # detected binary path
    # uwsgi socket 0 bound to UNIX address
  # PythonHome、Python Version
  # 是否有报错信息

  

# 查看启动成功的日志：
