CentOS 6.5下安裝Ambari 詳解

Apache Ambari是一種基於Web的工具，支援Apache Hadoop叢集的供應、管理和監控。Ambari目前已支援大多數Hadoop元件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeper、Sqoop和Hcatalog等。下面與大家分享在CentOS 6.5下安裝Ambari 的步驟。

一、前期環境準備

1.安裝epel源

2.安裝pdsh

yum -y install pdsh

3.在master和slave上設定hosts

cat /etc/hosts
127.0.0.1  localhost localhost.localdomain localhost4 localhost4.localdomain4
::1        localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.40.217  ambari
192.168.40.216  slave

4.設定免密碼登入

ssh-keygen  -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase): #輸入空格
Enter same passphrase again: #輸入空格
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
01:f9:c3:e6:e2:cc:46:1c:55:68:c4:2d:2b:eb:77:09 root@localhost.localdomain
The key's randomart image is:
+--[ RSA 2048]----+
|      .+.+.      |
|      ..* .      |
|      =.o      |
|      o *.      |
|    . *S.      |
|      = E        |
|    * . . .    |
|      * . o      |
|    . . .      |
+-----------------+
[root@ambari ~]# cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
[root@ambari ~]# scp ~/.ssh/authorized_keys master:/root/.ssh/
[root@ambari ~]# scp ~/.ssh/authorized_keys slave:/root/.ssh/

5.關閉selinux 和防火牆

二、安裝ambari

1.設定yum源

[root@ambari ~]# wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.0.1/ambari.repo
[root@ambari ~]# mv ambari.repo  /etc/yum.repos.d/

2.安裝ambari-server

[root@ambari ~]# yum  -y install ambari-server  #過程比較慢，ambari-server包有80M大小

3.本地設定

[root@ambari ~]# ambari-server setup
Using python  /usr/bin/python2.6

###這裡由於下載jdk速度過慢。我提前把jdk下載下來放到了/var/lib/ambari-server/resources/目錄
[root@ambari ~]# cd /var/lib/ambari-server/resources/
[root@ambari resources]# mv /root/jdk-7u67-linux-x64.tar.gz  .

4.啟動服務

[root@ambari ~]# ambari-server start
Using python  /usr/bin/python2.6
Starting ambari-server
WARNING: The hostname was not found in the reverse DNS lookup. This may result in incorrect behavior. Please check the DNS setup and fix the issue.

啟動ambari報錯

WARNING: The hostname was not found in the reverse DNS lookup. This may result in incorrect behavior. Please check the DNS setup and fix the issue. ‘
這個問題是由於沒有把主機名已經對應的ip加到/etc/hosts 導致的。

5.存取web

http://ip:8080  預設使用者是admin，密碼admin
