生成密钥传到各个节点去 让他们可以互相连接
[root@master ~]# ssh-keygen -t rsa -C “hbw1992@sina.com”
[root@master ~]# cd .ssh/
[root@master .ssh]# ll
total 12
-rw——- 1 root root 1679 Aug 25 12:36 id_rsa
-rw-r–r– 1 root root 398 Aug 25 12:36 id_rsa.pub
-rw-r–r–. 1 root root 191 Aug 19 22:03 known_hosts
cat id_rsa.pub
[root@master .ssh]# vi .ssh/authorized_keys
把id_rsa.pub加进去
[root@master ~]# scp -r /root/.ssh node1:/root/
配置hosts
vi /etc/hosts
192.168.199.200 master1.hbw.com master1
192.168.199.201 node1.hbw.com node1
192.168.199.202 node2.hbw.com node2
192.168.116.203 node3.hbw.com node3
scp /etc/hosts node1:/etc/hosts
reboot #重启系统
设置主机名为master1.hbw.com(配置hosts了不用做这步)
hostname master1.hbw.com #设置主机名为master1.hbw.com
vi /etc/hostname #编辑配置文件
master1.hbw.com #修改localhost.localdomain为master1.hbw.com
:wq! #保存退出
vi /etc/hosts #编辑配置文件
127.0.0.1 localhost master1.hbw.com #修改localhost.localdomain为master1.hbw.com
:wq! #保存退出
shutdown -r now #重启系统
