Install Ambari 2.2.0 from Public Repositories（Hadoop）
Step1: Download the Ambari repository on the Ambari Server host
For Redhat/CentOS/Oracle: cd /etc/yum.repos.d/ wget <ambari-repo-url> For SUSE: cd /etc/zypp/repos.d wget <ambari-repo-url> For Ubuntu/Debian: cd /etc/apt/sources.list.d wget <ambari-repo-url> |
Choose an appropriate <ambari-repo-url> based on the platform used:

Step 2: Install, Setup, and Start Ambari Server
Install Ambari Server from the public Ambari repository:
For Redhat/CentOS/Oracle: yum install ambari-server如果遇到 Another app is currently holding the yum lock; waiting for it to exit. 可以通过执行rm -rf /var/run/yum.pid 来强行解除锁定
For SUSE: zypper install ambari-serverFor Ubuntu/Debian: apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD apt-get update apt-get install ambari-server |
Run the setup command to configure your Ambari Server, Database, JDK, LDAP, and other options:
ambari-server setup |
Fixed a warnings：
--------------------------------------------------------------
A. Close SELinux：
1、临时关闭（不用重启机器）：
setenforce 0 ##设置SELinux 成为permissive模式
##setenforce 1 设置SELinux 成为enforcing模式
2、修改配置文件需要重启机器：
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可
--------------------------------------------------------------------------
--------------------------------------------------------------------------
B. Close iptables
1. Linux防火墙(Iptables)重启系统生效
- 开启： chkconfig iptables on
- 关闭： chkconfig iptables off
2.Linux防火墙(Iptables) 即时生效，重启后失效
- 开启： service iptables start
- 关闭： service iptables stop
--------------------------------------------------------------------------
Start Ambari Server:
ambari-server start |
Step 3: Deploy Cluster using Ambari Web UI
Open up a web browser and go to http://<ambari-server-host>:8080.
Log in with username admin and password admin and follow on-screen instructions.
ssh 无密码登录要使用公钥与私钥。linux下可以用用ssh-keygen生成公钥/私钥对，下面我以CentOS为例。
有机器A(192.168.1.155)，B(192.168.1.181)。现想A通过ssh免密码登录到B。 首先以root账户登陆为例。
1.在A机下生成公钥/私钥对。
-P表示密码，-P '' 就表示空密码，也可以不用-P参数，这样就要三车回车，用-P就一次回车。 该命令将在/root/.ssh目录下面产生一对密钥id_rsa和id_rsa.pub。
一般采用的ssh的rsa密钥: id_rsa 私钥 id_rsa.pub 公钥 下述命令产生不同类型的密钥 ssh-keygen -t dsa ssh-keygen -t rsa ssh-keygen -t rsa1
2.把A机下的/root/.ssh/id_rsa.pub 复制到B机的 /root/.ssh/authorized_keys文件里，先要在B机上创建好 /root/.ssh 这个目录，用scp复制。
由于还没有免密码登录的，所以要输入一次B机的root密码。
3.authorized_keys的权限要是600!!!
[dave@caprice dave]$ ssh 192.168.1.3 -v [I edited out the verbose output, and entered the password] [Remember kids, always use -v so dont try this at home :) ] [dave@julia dave]$ mkdir .ssh [dave@julia dave]$ chmod 700 .ssh [dave@julia dave]$ cd .ssh [dave@julia .ssh]$ touch authorized_keys [dave@julia .ssh]$ chmod 600 authorized_keys [dave@julia .ssh]$ cat ../identity.pub >> authorized_keys [dave@julia .ssh]$ rm ../identity.pub
//错误：INFO 2016-01-07 11:52:03,525 NetUtil.py:60 - Connecting to https://ha0.ggz.bluefir:8440/ca的解决方法：
如果已经错了，可以去每台机器/etc/ambari-agent/conf/ambari-agent.ini修改ambari-server主机信息
//设置jdk：ambari-server setup -j /opt/jdk1.8/
//解决openssl错误：yum update openssl
//手工安装ambari-agent的步骤
RHEL/CentOS/Oracle Linux 6
-
Install the Ambari Agent on every host in your cluster.
yum install ambari-agent -
Using a text editor, configure the Ambari Agent by editing the
ambari-agent.inifile as shown in the following example:vi /etc/ambari-agent/conf/ambari-agent.ini[server] hostname=<your.ambari.server.hostname>url_port=8440secured_url_port=8441 -
Start the agent on every host in your cluster.
ambari-agent startThe agent registers with the Server on start.
//遇到The following hosts have Transparent Huge Pages (THP) enabled. THP should be disabled to avoid potential Hadoop performance issues.错误的解决方法：
解决办法,在Linux下执行：
echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/defrag
