查询哪个程序占用了443端口

netstat -pntl | grep 443

显示为apache2占用

tcp6 0 0 :::443 :::* LISTEN 6836/apache2

将系统python版本切换为3（aiohttp依赖python3）

ls /usr/bin/python* update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1 update-alternatives --install /usr/bin/python python /usr/bin/python3.7 2 update-alternatives --config python
