Python+Selinum环境配置

apt-get remove 会删除软件包而保留软件的配置文件

apt-get purge 会同时清除软件包和软件的配置文件 

virtualenv -p /usr/local/bin/python3.6 --no-site-packages venv

source my_project/bin/activate

deactivate 退出

 supervisor 安装配置： 

apt install supervisor 

[program:ind]
command=python3 /root/robot/IND/start.py
stderr_logfile=/root/robot/logs/ind/err.log
stdout_logfile=/root/robot/logs/ind/out.log
autostart=true
autorestart=true
user=root

主的配置：
[inet_http_server]
port=0.0.0.0:9001
username=admin
password=12345
exitcodes=1

supervisorctl stop all

Error Another program is already listening on a port that one of our HTTP servers is configured to use

ps -ef | grep supervisord

kill -9

使用selinum配置确实麻烦，可以使用pyppeteer

解析html使用pyquery
