Centos 6.5 Ambari 2.2.2 安裝

Ambari安裝大數據生態圈中的工具方便快捷。

• 1、服務器環境設置

一、使用虛擬機虛擬出3臺centos6.5

    10.211.55.7 master

    10.221.55.8 node1

    10.221.55.9 node2

二、修改服務器hostname，三臺服務器都要改

vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=master #將HOSTNAME 改成 本身想設置的主機名 

vi /etc/hosts #在hosts最後添加服務器IP及 主機名
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.211.55.7 master
10.211.55.8 node1
10.211.55.9 node2

3.關閉防火牆，三臺服務器都要關閉

chkconfig iptables off

4.更新插件

yum update #更新插件

5.重啓服務器

• 2、查看Ambari官網，能夠經過yum安裝。

https://cwiki.apache.org/confluence/display/AMBARI/Install+Ambari+2.2.2+from+Public+Repositories

一、安裝server端，只須要安裝一個，我安裝在了master上

​
For Redhat/CentOS/Oracle:
  cd /etc/yum.repos.d/
  wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.2.2.0/ambari.repo

yum install ambari-server

ambari-server setup #安裝時一直回車，走默認便可

ambari-server start

​

 

二、安裝agent，我安裝在了node1和node2上

For Redhat/CentOS/Oracle:
  cd /etc/yum.repos.d/
  wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.2.2.0/ambari.repo

yum install ambari-agent

#安裝完成後，修改agent配置文件

vi /etc/ambari-agent/conf/ambari-agent.ini
.
.
[server]
hostname=master #將hostname 改成安裝server端的主機名
url_port=8440
secured_url_port=8441
.
.

 

三、啓動agent

ambari-agent start

• 3、添加工具

瀏覽器輸入 master:8080 ,帳號密碼 都是admin。這一段網上有不少，我就先不寫了。

ps：安裝node2節點時始終沒法鏈接到server，查看日誌

解決方法：

一下是官方論壇中給出的方法，很好

Platforms:

• RHEL / CentOS 6.5
• Ambari 1.4 or later

Root Cause: The OpenSSL library available and installed by default on RHEL/CentOS 6.5 has a bug. Refer to https://bugzilla.redhat.com/show_bug.cgi?id=1025598 for detailed information on the bug.

Remedy:

1. Check the OpenSSL library version installed on your host(s):

   rpm -qa | grep openssl
   
   openssl-1.0.1e-15.el6.x86_64

2. If the output says openssl-1.0.1e-15.x86_64 (1.0.1 build 15) you will need to upgrade the OpenSSL library by running the following command:

   yum upgrade openssl

3. Verify you have the newer version of OpenSSL (1.0.1 build 16):

   rpm -qa | grep openssl

   openssl-1.0.1e-16.el6.x86_64

4. Restart Ambari Agent(s) and Click Retry Failed on the Wizard

 

按照上面的操做成功鏈接，原來是openssl 版本太低，因爲以前兩臺服務器 都yum update 因此沒有出現這個問題。經過這件事情咱們發現，一、任何錯誤都是有跡可循的，要善於查日誌；二、新作完系統 要先更新 yum update。
