linux服务器秘钥

生成秘钥
[root@es1 .ssh]# ssh-keygen -t rsa

服务器之间的秘钥传输认证文件
[root@es1 ~]# cat id_rsa.pub >>authorized_keys
[root@es1 ~]# chmod 600 authorized_keys

传输给其它服务器
[root@es1 ~]# scp -rp .ssh 192.168.24.128:~
[root@es1 ~]# scp -rp .ssh 192.168.24.139:~

hosts 解析
[root@es1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.24.140 es1
192.168.24.128 es3
192.168.24.139 es2
