服务器环境配置

 

1、本机sudo权限;

2、单点配置:

(1)配置/etc/profile的环境;

(2)配置/etc/ssh/ssh_config、/etc/ssh/sshd_config的端口配置;

(3)配置/etc下的hdfs-site.xml、core-site.xml、mapred-site.xml、yarn-site.xml;

4)单点配置完以后,可以启动跑跑实例,/sbin下:

Hadoop namenode format(格式化一下)

./hadoop-daemon.sh start namenode

 

3、互连免密登陆;

(1)ssh-keygen生成公钥、秘钥;

(2)cat /home/haoxin/.ssh/id_rsa.pub >>~/.ssh/authorized_keys/;

(3)scp -r ~/ssh/* 主机名@ip:~/ssh/;

(4)域名互通:vim /etc/hosts;
