nginx，uwsgi

配置

uwsgi

啟動配置檔案

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

[uwsgi]
#application's base folder，配置為專案的根目錄
base = /home/liuwei/mycode/py/FlaskDemo

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

# 專案依賴的環境目錄
home = /home/liuwei/mycode/py/envs/flaskdemoenv
pythonpath 
 
= %(base)

#socket file's location，生成nginx依賴的檔案，其中%n表示當前檔案的名字
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

sudo mkdir -p /var/log/uwsgi
sudo chown -R liuwei:liuwei /var/log/uwsgi

啟動

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

# 當啟動後，就會在專案目錄下生成uwsgi.sock檔案，這個檔案被nginx依賴，所以你要先啟動uwsgi

#日誌需要注意引數：
    # current working directory
    # detected binary path
    # uwsgi socket 0 bound to UNIX address

 PythonHome、Python Version
  # 是否有報錯資訊
