Centos7 cannot use ssh Login and Solution

Today, the project team reported that a Centos7 server could not log on via SSH, so after logging on to the system locally, I found that the SSH service was not started, this method mainly uses the netstat-anlpt | grep 22 Method for viewing;

Speaking of this, if it is Centos7, if we want to use the netstat command, we need to install net-tools before using it.

Yuminstatllnet-tools-y ---- install netstat Tools

Failed to start sshd service manually. error message (port 22 is not listened)

There is no independent log for ssh in Centos7, so in message

Tail–f /var/log/message /usr/sbin/ The sshd file is missing.

Cd /usr/sbin/ Does not display the sshd file or directory

So we need to reinstall it.

yumreinstallopenssh-server

Installation Complete

After installation, the file contains ssh file information.

Restart the sshd file.

Systemctlstartsshd --- start the sshd service
