prerequisites:
1. Because the compilation time is relatively long, you need to set the xshell client remote connection tool to not drop the line
2. Server settings
vi /etc/ssh/sshd_config
Remove the pound sign before ClientAliveInterval 0 and ClientAliveCountMax 3. And change the value of ClientAliveInterva to 60. Then service sshd restart restarts the ssh service.
