    1. vim /ect/hostname
    2. //添加ip master
    3. vim /etc/hosts
    5. vim /etc/sysconfig/network-scripts/ifcfg-ens32
    6. //添加配置
    7. BOOTPROTO="static"
    8. IPADDR=192.168.66.133
    9. NETWORK=255.255.255.0

    14. Restarting network (via systemctl): 
    15. Job for network.service failed because the control process exited with error code.
    16. See "systemctl status network.service" and "journalctl -xe" for details.
    17. 解决：
    18. systemctl stop NetworkManager
    19. systemctl disable NetworkManager
    20. systemctl start network.service
    23. ssh-keygen -t rsa //一直回车
    24. ssh-copy-id master
    25. cd ~
    26. ls -al //查看有无.ssh
    27. cd .ssh
    28. more authorized_keys
    29. ssh master
