#### 二、 环境准备

 

1、主机  
172.19.80.2 SY-001.hadoop  
172.19.80.3 SY-002.hadoop  
172.19.80.4 SY-003.hadoop  
172.19.80.5 ambari-mysql

 

2、安装基础环境 (在主机SY-001.hadoop，SY-002.hadoop，SY-003.hadoop部署)  
（1）安装基本包  
$ yum install openssh wget vim openssh-clients openssl gcc openssh-server mysql-connector-odbc -y  
$ systemctl enable sshd && systemctl start sshd

 

（2）安装mysql jdbc 驱动  
$ yum install mysql-connector-java -y

 

（3）安装JDK  
版本要求：  
Oracle JDK 1.8 64-bit (minimum JDK 1.8.0_77) (default)  
Oracle JDK 1.7 64-bit (minimum JDK 1.7_67)  
OpenJDK 8 64-bit (not supported on SLES)  
OpenJDK 7 64-bit (not supported on SLES)

 

$ mkdir /usr/local/src/Ambari/  
$ wget http://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-linux-x64.tar.gz?AuthParam=1480914946_a78f7ba2e70d2f0abed0b0af73c74214  
$ mkdir -p /opt/java/ && tar xf jdk-8u112-linux-x64.tar.gz -C /opt/java  
$ vim /etc/profile  
添加下面内容：  
export JAVA_HOME=/opt/java/jdk1.8.0_112  
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar  
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin  
$ source /etc/profile

 

（4）配置SSH免密码登录  
主节点里root用户登录执行如下步骤  
$ ssh-keygen  
$ cd ~/.ssh/  
$ cat id_rsa.pub >> authorized_keys  
$ chmod 600 ~/.ssh/authorized_keys  
把各个主机上公钥id_rsa.pub文件内容放到各个主机authorized_keys中

 

（5）开启NTP服务  
$ yum -y install ntp  
$ systemctl is-enabled ntpd  
$ systemctl enable ntpd  
$ systemctl start ntpd

 

（6）检查DNS和NSCD  
ambari在安装时需要配置全域名，所以需要检查DNS。为了减轻DNS的负担, 建议在节点里用 Name Service Caching Daemon (NSCD)  
$ cat /etc/hosts  
172.19.80.2 SY-001.hadoop  
172.19.80.3 SY-002.hadoop  
172.19.80.4 SY-003.hadoop  
172.19.80.5 ambari-mysql

 

（7）每台节点里配置FQDN，如下以主节点为例  
$ cat /etc/sysconfig/network  
NETWORKING=yes  
HOSTNAME=SY-001.hadoop

 

（8）关闭防火墙和SELinux  
$ systemctl disable firewalld  
$ systemctl stop firewalld  
临时关闭，不用重启机器：  
$ setenforce 0  
修改配置文件让机器重启也生效：  
$ cat /etc/sysconfig/selinux  
SELINUX=disabled
