1. 启动uwsgi：sudo uwsgi --ini uwsgi,ini #uwsgi.ini为启动文件
2. 查看uwsgi是否启动成功：ps aux | grep uwsgi
3. 发现没有启动成功
4. 去uwsgi.log(在uwsgi.ini同级目录下)排错日志中找原因，发现报错如下

chdir() to /home/ubuntu/day01   #项目目录
chdir(): No such file or directory [core/uwsgi.c line 2623]

在网上搜到结果，需要将uwsgi.ini中用#写的备注都删掉
5. 然后再次启动uwsgi,发现还是不行，此时报错如下

bind(): Cannot assign requested address [core/socket.c line 769]

此时修改uwsig.ini中的socket地址如下

#原来
socket = 公网ip:uwsgi端口
#现在
socket = 127.0.0.1:uwsgi端口

6. 再次启动uwsgi,成功，uwsgi.log日志中显示如下

*** uWSGI is running in multiple interpreter mode ***
