二、环境部署

所有机器执⾏：  

1.配置静态IP、DNS
⾸先，进⼊到⽹卡，然后编辑。
vim /etc/sysconfig/network-scripts/ifcfg-eth0
配置完静态IP后重启⽹络服务
systemctl restart network.service

　　

2.配置主机名
# vim /etc/hostname 
HOSTNAME= 主机名

或者：
hostnamectl set-hostname master.hadoop
hostnamectl set-hostname ambari01.hadoop
hostnamectl set-hostname ambari02.hadoop
hostnamectl set-hostname ambari03.hadoop
hostnamectl set-hostname ambari04.hadoop
hostnamectl set-hostname ambari05.hadoop
hostnamectl set-hostname ambari06.hadoop

　　

3. 配置hosts⽂件
[root@master ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.30 master master.hadoop
192.165.1.31 ambari01 ambari01.hadoop
192.165.1.32 ambari02 ambari02.hadoop
192.165.1.33 ambari03 ambari03.hadoop
192.165.1.34 ambari04 ambari03.hadoop
192.165.1.35 ambari05 ambari03.hadoop
192.165.1.36 ambari06 ambari03.hadoop

　　

 

4 .关闭防⽕墙与SElinux
systemctl disable firewalld.service 
systemctl stop firewalld.service

关闭selinux
vim /etc/sysconfig/selinux 
# 将SELINUX=enforcing改为SELINUX=disabled

统⼀把所有机器重启⼀遍！让配置⽣效！ 

 

5. SSH⽆密码登陆
在master节点执⾏如下命令：
ssh-keygen -t rsa （回⻋后再按连续三个回⻋） 
cd .ssh/ cat id_rsa.pub >> authorized_keys 
分别在其他三台机器上创建/root/.ssh⽬录，
如下： 
mkdir /root/.ssh 然后将authorized_keys拷⻉到其他几台机器的.ssh⽬录，
如下： 
scp authorized_keys ambari01:/root/.ssh/ 
scp authorized_keys ambari02:/root/.ssh/ 
scp authorized_keys ambari03:/root/.ssh/ 
或者： ssh-copy-id -i ~/.ssh/id_rsa.pub ambari01 
ssh-copy-id -i ~/.ssh/id_rsa.pub ambari02 
ssh-copy-id -i ~/.ssh/id_rsa.pub ambari03

 

验证配置： 

ssh ambari01 date; ssh ambari02 date; ssh ambari03 date;

 

5. 修改YUM源(可选) 

mkdir /etc/yum.repos.d/backup
mv  /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all && yum makecache fast
