【Linux基础】建立多服务器互信关系

配置用户ssh互信关系，支持多台机器间的无密码访问

1. 创建ssh公私钥：ssh-keygen
   

2. 将Hadoop002、Hadoop003的公钥文件传给Hadoop001
   

3. 在hadoop001中创建信任文件

[zookeeper@hadoop001 .ssh]$ cat id_rsa.pub > authorized_keys
[zookeeper@hadoop001 .ssh]$ cat id_rsa2.pub >> authorized_keys
[zookeeper@hadoop001 .ssh]$ cat id_rsa3.pub >> authorized_keys

6. 将信任关系文件传到hadoop002和hadoop003机器上


7. 修改hadoop001信任文件权限

authorized_keys 文件若是非root用户，则权限修改为640，root权限则不需要修改

8. 测试配置是否成功
