这个故障 很绕，但遇到的朋友一下就明白
先发下解析思路
rc.local开启一个用于建立screen 脚本xxxxx_s.sh
#!/bin/bash
ssh -t localhost
/usr/bin/screen -dmS ss1
sleep 1
/usr/bin/screen -x -S ss1 -p 0 -X stuff "w"
/usr/bin/screen -S ss1 -X stuff 'ssh -t localhost'`echo -ne '\015'`
/usr/bin/screen -S ss1 -X stuff 'date'`echo -ne '\015'`
/bin/nohup /usr/bin/syncthing &> /dev/null &
再crontab 中进行 * * * * * 的xxxxx_crontab.sh运行
#!/bin/bash
screenNum=`screen -ls |wc -l `;[[ $screenNum -lt 5 ]] && xxxxx_s.sh
发一下systemctl 使用中的代码
