CentOS 6 Ambari Hadoop平台的安装（本地库）

配置详情

# vi /etc/hosts

127.0.0.1  localhost localhost.localdomain localhost4 localhost4.localdomain4

::1        localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.31.3    < 主机的全名，如 john.smith>

配置详情

1)        确认是否已经安装ssh

# rpm -qa | grep ssh

# yum install ssh //上条命令无输出时

2)        修改配置文件

# vi /etc/ssh/sshd_config

RSAAuthentication yes         # 启用 RSA 认证

PubkeyAuthentication yes       # 启用公钥私钥配对认证方式

AuthorizedKeysFile .ssh/authorized_keys      # 公钥文件路径

# service sshd restart //重启 sshd 服务

3)        生成秘钥

$ ssh-keygen -t rsa

Tips：敲完命令，一直回车，直到命令结束生成如下类似的图案

图 1 -1 生成秘钥

图 1 -2 生成的秘钥

4)        添加公钥

$ cat .ssh/id_rsa >> .ssh/authorized_keys

Tips：.ssh 700, authorized_keys 644

图 1 -3 配置成功

命令：临时关闭

# setenforce 0
