在使用ssh鏈接時出現:php
$ ssh localhost ssh: connect to host localhost port 22: Connection refused
$ ss -tnlp State Recv-Q Send-Q Local Address:Port Peer Address:Port
從命令結果能夠看到,SSH的監聽端口(22)並無linux
$ systemctl status sshd.service ● sshd.service - OpenSSH Daemon Loaded: loaded (/usr/lib/systemd/system/sshd.service; disabled; vendor preset: disabled) Active: inactive (dead)
sshd.service沒有沒有激活ssh
ssh服務沒有啓動,端口未處於監聽狀態code
