步骤1. 修改sshd_config文件

修改文件/etc/ssh/sshd_config为如下内如：

尤其注意需要将UsePAM yes注释为# UsePAM yes样式。

#    $OpenBSD: sshd_config,v 1.101 2017/03/14 07:19:07 djm Exp $# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key
#HostKey /etc/ssh/ssh_host_ed25519_key# Ciphers and keying
#RekeyLimit default none# Logging
#SyslogFacility AUTH
#LogLevel INFO# Authentication:#LoginGraceTime 2m
PermitRootLogin yes
#PermitRootLogin without-password
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10PubkeyAuthentication no# Expect .ssh/authorized_keys2 to be disregarded by default in future.
#AuthorizedKeysFile .ssh/authorized_keys .ssh/authorized_keys2#AuthorizedPrincipalsFile none#AuthorizedKeysCommand none
#AuthorizedKeysCommandUser nobody# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don't read the user's ~/.rhosts and ~/.shosts files
#IgnoreRhosts yes# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication yes
#PermitEmptyPasswords no
PermitEmptyPasswords yes# Change to yes to enable challenge-response passwords (beware issues with
# some PAM modules and threads)
ChallengeResponseAuthentication no# Kerberos options
#KerberosAuthentication no
#KerberosOrLocalPasswd yes
#KerberosTicketCleanup yes
#KerberosGetAFSToken no# GSSAPI options
#GSSAPIAuthentication no
#GSSAPICleanupCredentials yes
#GSSAPIStrictAcceptorCheck yes
#GSSAPIKeyExchange no# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
#UsePAM yes#AllowAgentForwarding yes
#AllowTcpForwarding yes
#GatewayPorts no
X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes
#PermitTTY yes
PrintMotd no
#PrintLastLog yes
#TCPKeepAlive yes
#UseLogin no
#PermitUserEnvironment no
#Compression delayed
#ClientAliveInterval 0
#ClientAliveCountMax 3
#UseDNS no
#PidFile /var/run/sshd.pid
#MaxStartups 10:30:100
#PermitTunnel no
#ChrootDirectory none
#VersionAddendum none# no default banner path
#Banner none# Allow client to pass locale environment variables
AcceptEnv LANG LC_*# override default of no subsystems
Subsystem   sftp    /usr/lib/openssh/sftp-server# Example of overriding settings on a per-user basis
#Match User anoncvs
#   X11Forwarding no
#   AllowTcpForwarding no
#   PermitTTY no
#   ForceCommand cvs server

步骤2. 重启服务

然后重启服务：service sshd restart
