阿里云Hadoop集群部署(2)-配置多台机器互信认

前面购买好阿里云机器后,接下来进行集群机器间的互信任操作

购买配置请参考

• 小技巧 在xshell中同时操作多个窗口(鼠标右键,选择如下如图箭头所示)

1. 创建用户

[root@hadoop002 ~]# useradd hadoop

2. 上传文件(root)

[root@hadoop001 software]$ ll
total 509828
-rw-r--r-- 1 root root 311585484 Nov 26 14:23 hadoop-2.6.0-cdh5.7.0.tar.gz
-rw-r--r-- 1 root root 173271626 Nov 26 14:23 jdk-8u45-linux-x64.gz
-rw-r--r-- 1 root root  37191810 Nov 26 14:23 zookeeper-3.4.13.tar.gz

3. 复制到每台机器上

scp root@ip/home/hadoop/software

[hadoop@hadoop001 software]$ hostname -i
172.18.97.104
[hadoop@hadoop001 software]$ scp root@172.18.97.104/home/hadoop/software

4. 修改上传软件权限

[root@hadoop001 ~]# chown -R hadoop:hadoop /home/hadoop/software/*

5. 修改hosts文件

[root@hadoop001 ~]# vim /etc/hosts

172.18.97.104   hadoop001       hadoop001
172.18.97.106   hadoop002       hadoop002
172.18.97.105   hadoop003       hadoop003
