Centos 7.3 install Ambari2.5

配置三台主机
vi /etc/hosts
172.16.19.91 ambari01
172.16.19.92 ambari02
172.16.19.93 ambari03

vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=ambari01


三台主机关闭防火墙以及selinux
systemctl disable firewalld
systemctl stop firewalld

vi /etc/sysconfig/selinux
SELINUX=disabled

主创建账号
adduser ambari
passwd ambari

主安装插件
yum install openssh-clients lrzsz ntp mysql-connector-java -y
systemctl is-enabled ntpd
systemctl enable ntpd
systemctl start ntpd

备安装
yum install openssh-clients lrzsz ntpac
systemctl is-enabled ntpd
systemctl enable ntpd
systemctl start ntpd

主设备创建从不配置
mkdir .ssh
ssh-keygen -t rsa //执行命令一路回车，生成秘钥
cd .ssh
ls
id_rsa id_rsa.pub
cat id_rsa.pub >> authorized_keys //将公钥保存到authorized_keys认证文件中
ls
cd ..
chmod 700 .ssh
chmod 600 .ssh/*

在主拷贝到从节点authorized_keys
scp /root/.ssh/authorized_keys root@172.16.19.92:/root/.ssh/authorized_keys
scp /root/.ssh/authorized_keys root@172.16.19.93:/root/.ssh/authorized_keys
