在linux后台运行python脚本 加-u参数才能打印日志
 nohup python3 -u sock_ssh_server.py >py_run.log 2>1 &

自动拉起 sh脚本
 
 #!/bin/sh
 source ~/.bash_profile
  ps -ef|grep -v grep|grep '/usr/local/bin/python3 -u /root/sock_ssh_server.py' > /dev/null 2>&1
 
 if [ $? -eq 0 ]
 then
         echo `date`"------python脚本正在运行" >> ~/result.log
 else
          nohup /usr/local/bin/python3 -u ~/sock_ssh_server.py > ~/py_run.log 2>1 &
