Ambari学习15_CentOS6.5下安装Ambari2.4全过程

Ambari安装

一、前期准备

CentOS应该使用英文版本

1、网络

修改/etc/sysconfig/network-scripts/ifcfg-em1，使网络开机时自动连接

即设置：ONBOOT=yes

2、系统文件

修改/etc/hosts和/etc/sysconfig/network

3、跟新openssl

查看openssl版本：

openssl version –a

和

rpm -qa | grep openssl

结果是：
openssl-1.0.1e-15.el6.x86_64

这个版本比较旧，需要对它进行升级

升级命令：

yum upgrade openssl

以上操作此详细过程：

[root@slave1szx]# rpm -qa | grep openssl

openssl-1.0.1e-15.el6.x86_64

[root@slave1szx]# yum upgrade openssl

……

[root@slave1szx]# rpm -qa | grep openssl

openssl-1.0.1e-48.el6_8.3.x86_64

4、禁用SELinux

可以选择临时性和永久性的禁用。

临时性，使用命令：

setenforce 0

永久性，修改/etc/selinux/config文件

SELINUX=disabled

SELINUXTYPE=targeted

5、禁用iptables

service iptables stop

如下：

[root@masterszx]# service iptables stop

iptables:Setting chains to policy ACCEPT: filter[ OK ]

iptables:Flushing firewall rules:[ OK ]

iptables:Unloading modules:[ OK ]

[root@masterszx]#

6、安装SSH

Root用户下启动服务：

service sshd restart

在普通户下操作

登录本机，检查是否成功，此时，需要密码：ssh master

退出登录，添加授权

cd ~/.ssh/

ssh-keygen -t rsa

有提示，一直按回车

cat id_rsa.pub >> authorized_keys

在root用户下操作

修改权限

修改文件"authorized_keys"权限

chmod 700 authorized_keys

修改SSH配置文件"/etc/ssh/sshd_config"的下面内容

vim /etc/ssh/sshd_config

###############

RSAAuthentication yes # 启用 RSA 认证

PubkeyAuthentication yes # 启用公钥私钥配对认证方式

AuthorizedKeysFile .ssh/authorized_keys # 公钥文件路径（和上面生成的文件相同）

###############

重启SSH

service sshd restart

在普通用户下操作

登录本机，此时不需要密码

ssh master

在slave1和slave2上进行相同操作

将公钥id_rsa.pub分别拷贝到authorized_keys

cat id_rsa.pub >>authorized_keys

7、root下设置ssh

Root下的ssh和普通用户下的ssh

Root下的目录

[root@master.ssh]# pwd

/root/.ssh

普通用户下的目录

[szx@slave2.ssh]$ pwd

/home/szx/.ssh

它们的目录不同

8、Java更新

暂时不进行更新操作

9、Python

保证Python版本大于2.6

10、关闭Linux的THP服务

#centos6

vi/etc/grub.conf，添加transparent_hugepage=never

#centos7:

vi/etc/default/grub

在有CMDLINE一行添加 transparent_hugepage=never

grub2-mkconfig-o /boot/grub2/grub.cfg

systemctldisable tuned

重启之后，用下面的命令检查：

cat/sys/kernel/mm/redhat_transparent_hugepage/enabled

有 [never]则表示THP被禁用

11、启动ntpd

/etc/init.d/ntpd start

否则，会出现ntpd Not running on 3 hosts问题

12、禁止PackageKit

这个步骤每台都需要做，因为在使用yum安装期间有可能导致yum被锁，安装过程报错。agent会用到yum安装hadoop及上层组件，而server也要用yum安装ambari。

vi/etc/yum/pluginconf.d/refresh-packagekit.conf 修改其中配置将enabled后面数值置0。

二、安装过程

1、下载Ambari的公共库文件

首先需要获取Ambari的公共库文件(public repository)，登录到Linux主机并执行下面的命令(也可以自己手工下载)：

旧：

wgethttp://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.0.1/ambari.repo

新：

wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.4.0.1/ambari.repo

或：

wget -nvhttp://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.4.0.1/ambari.repo-O /etc/yum.repos.d/ambari.repo

（不用拷贝）

2、拷贝到Linux的系统目录/etc/yum.repos.d/

将下载的ambari.repo文件拷贝到Linux的系统目录/etc/yum.repos.d/，拷贝完后，我们需要获取该公共库的所有的源文件列表。

3、查看

yum clean all

yum list|grep ambari

如果可以看到Ambari的对应版本的安装包列表，说明公共库已配置成功。然后就可以安装Ambari的package了。

4、安装

yum install ambari-server

5、配置

ambari-server setup

在这个交互式的设置中，采用默认配置即可。Ambari会使用Postgres数据库，默认会安装并使用Oracle的JDK。默认设置了Ambari GUI的登录用户为admin/admin。并且指定Ambari Server的运行用户为root。

备注（详细的设置过程）：

旧：

[root@master~]# amari-server setup

bash:amari-server: command not found

[root@master~]# ambari-server setup
