修改配置

1.vi etc/ssh/sshd_config

      6 # This sshd was compiled with PATH=/usr/local/bin:/usr/bin

      7

      8 # The strategy used for options in the default sshd_config shipped with

      9 # OpenSSH is to specify options with their default value where

     10 # possible, but leave them commented.  Uncommented options override the

     11 # default value.

     13 # If you want to change the port on a SELinux system, you have to tell

     14 # SELinux about this change.

     15 # semanage port -a -t ssh_port_t -p tcp #PORTNUMBER

     16 #

     17 Port 22

     18 #AddressFamily any

     41 #MaxSessions 10



找到17，19，20，38行。去掉#

接着开启sshd服务，检查服务是否开启

    service sshd start

    ps -e | grep sshd

开机自启

    systemctl enable sshd.service
