Centos 7 SSH connection timeout automatic disconnection solution

Recently, I was installing software on Centos 7, and it automatically disconnected after a while without looking at it. I didn’t know the progress of the software installation. I was so angry that I directly changed the sshd_config file, and I felt much better instantly.

1. Edit sshd configuration file

    # vi /etc/ssh/sshd_config

    找到

    #ClientAliveInterval 0
    #ClientAliveCountMax 3

    修改为

    ClientAliveInterval 60
    ClientAliveCountMax 3

2. Restart the sshd service

    # systemctl restart sshd

In this way, the connection to centos7 will not be interrupted by timeout even if it is not operated for a long time.
