修改CentOS主機名
1.開啟network檔案
[[email protected] ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=yxy(你要修改的主機名)
2.修改系統主機表文件
[[email protected] ~]# vi /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 127.0.0.1 yxy localhost.localdomain localhost4 localhost4.localdomain4(增加這一行)
3.重啟系統
[[email protected] ~]# reboot Broadcast message from [email protected] (/dev/pts/0) at 0:20 ... The system is going down for reboot NOW! [[email protected] ~]#
設定免密登入
設定免密登入:
[[email protected] ~]# ssh-keygen (按3個回車)
[[email protected] ~]# ssh-copy-id yxy(主機名) 1032763126(密碼)
若出現-bash: ssh-copy-id: command not found
先用命令安裝
[[email protected] ~]# yum -y install openssh-clients
安裝之後再用
[[email protected] ~]# ssh-copy-id yxy 1032763126
測試免密登入是否生效:
[[email protected] ~]# ssh yxy
