2.改ip這塊結合這個播客看，有詳細介紹，我只不過是總結了下：http://blog.csdn.net/wanz2/article/details/52820876
配置靜態IP：
靜態IP地址配置主要用到以下三個文件：
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network
/etc/resolv.conf
1).[root@ambari-server3 ~]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=ambari-server3
NTPSERVERARGS=iburst
GATEWAY=192.168.182.2
2).[root@ambari-server3 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
UUID=55d620df-ca54-4907-bac5-f8f6fb6bb2f1
ONBOOT=yes
NM_CONTROLLED=yes
HWADDR=00:0C:29:DD:52:B6
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
LAST_CONNECT=1515859956
#這幾個除了dhcp改爲static外，下面幾個都是加上去的，這個因人而異
BOOTPROTO=static
IPADDR=192.168.182.132
NETMASK=255.255.255.0
GATEWAY=192.168.182.2
DNS1=192.168.182.2
DNS2=8.8.8.8
3).上一步配置完成後，系統會在/etc/resolv.conf文件中自動寫入DNS服務器地址
[root@ambari-server3 ~]# more /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.182.2
nameserver 8.8.8.8
重啓網絡服務：
[root@ambari-server3 ~]# service network restart
正在關閉接口 eth0： 設備狀態：3 (斷開連接)
[確定]
關閉環回接口： [確定]
彈出環回接口： [確定]
彈出界面 eth0： 活躍連接狀態：激活的
活躍連接路徑：/org/freedesktop/NetworkManager/ActiveConnection/4 [確定]
打開ssh服務：
[root@ambari-server3 ~]# service sshd status
openssh-daemon (pid 1685) 正在運行...
[root@ambari-server3 ~]# service sshd start
[root@ambari-server3 ~]# chkconfig sshd on #設置開機運行ssh
[root@ambari-server3 ~]# chkconfig --list sshd
sshd 0:關閉 1:關閉 2:啓用 3:啓用 4:啓用 5:啓用 6:關閉
這臺節點就算完事了，有幾臺節點，就對應的改幾次、
3.各三臺機器做免密鑰：
我這裏ambari-server3是主節點：
1).先配置三臺機器的hosts文件：三臺都要做，一樣的；
[root@ambari-server3 .ssh]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.182.130 ambari-server1
192.168.182.131 ambari-server2
192.168.182.132 ambari-server3
[root@ambari-server1 .ssh]# vim /etc/hosts
[root@ambari-server2 .ssh]# vim /etc/hosts
2).需求：準備安裝ambari-server3（192.168.182.132）機器，需要到所有的機器都免密，包括本機。
在準備安裝ambari-server3（192.168.182.132）的機器上生成祕鑰
[root@ambari-server3 source]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
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:
33:21:02:fd:00:3a:d8:61:97:25:55:83:64:19:bb:52 root@ambari-server3
The key's randomart image is:
+--[ RSA 2048]----+
| =oo=*=o |
|.+ ++oo. . |
|+ . .oE . |
| . o.o . |
| . . S |
| . o |
| |
| |
| |
+-----------------+
3).配置ambari-server3（192.168.182.132）機器到所有機器的免密
包括自己本身
ssh-copy-id [email protected]
ssh-copy-id [email protected]
ssh-copy-id [email protected]
[root@ambari-server3 .ssh]# ssh-copy-id [email protected]
[email protected]'s password:
Now try logging into the machine, with "ssh '[email protected]'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
出現這個不影響免密登陸，剛測試了
[root@ambari-server3 .ssh]# ssh 192.168.182.130Last login: Sun Jan 14 11:49:22 2018 from ambari-server3
[root@ambari-server1 ~]# hostname

[root@ambari-server1 ~]# exit
logout
Connection to 192.168.182.130 closed.
[root@ambari-server3 .ssh]# hostname
ambari-server3
[root@ambari-server3 .ssh]# ssh-copy-id [email protected]
[email protected]'s password:
Now try logging into the machine, with "ssh '[email protected]'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
[root@ambari-server3 .ssh]# ssh-copy-id [email protected]
The authenticity of host '192.168.182.132 (192.168.182.132)' can't be established.
RSA key fingerprint is ad:4f:3d:d2:02:6d:6f:5b:44:97:b7:a1:1c:e3:5e:ff.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.182.132' (RSA) to the list of known hosts.
[email protected]'s password:
Now try logging into the machine, with "ssh '[email protected]'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
[root@ambari-server3 .ssh]# ssh 192.168.182.131
Last login: Sun Jan 14 11:51:14 2018 from ambari-server3
[root@ambari-server2 ~]# exit
logout
Connection to 192.168.182.131 closed.
[root@ambari-server3 .ssh]# ssh 192.168.182.132
Last login: Sun Jan 14 10:22:37 2018 from 192.168.182.1
[root@ambari-server3 ~]# exit
logout
Connection to 192.168.182.132 closed.
到這裏主節點到各臺子節點的面密就做完了
4.裝ambari必須要的組件：jdk、mysql
1).jdk好裝，就不做詳細介紹了；
[root@ambari-server3 source]# rpm -qa | grep jdk
java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
[root@ambari-server3 source]# clear
[root@ambari-server3 source]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
[root@ambari-server3 source]# rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
[root@ambari-server3 source]# tar -zxvf jdk-8u73-linux-x64.gz -C /usr/java/
[root@ambari-server3 source]# vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_73
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
[root@ambari-server3 source]# source /etc/profile
[root@ambari-server3 source]# java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
[root@ambari-server3 source]# java
用法: java [-options] class [args...]
...
2).着重講下mysql的安裝：
ambari安裝後面會用到mysql作爲原數據庫，這塊出問題是最多啊，myql搞錯了，後面還不好卸載，所以在裝mysql時候一定要小心；
自己玩測試機，密碼啥的最好設置一個一樣的，簡單好記的：
[root@ambari-server3 java]# rpm -qa | grep mysql*
mysql-libs-5.1.71-1.el6.x86_64
[root@ambari-server3 java]# rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64
命令安裝mysql：
[root@ambari-server3 java]# yum install mysql mysql-server mysql-devel -y
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
....
Complete!
[root@ambari-server3 java]# chkconfig --list | grep mysql
mysqld 0:關閉 1:關閉 2:關閉 3:關閉 4:關閉 5:關閉 6:關閉
[root@ambari-server3 java]# service myqld status
myqld: 未被識別的服務
#注意上面這個報錯：
[root@ambari-server3 java]# service mysqld start
初始化 MySQL 數據庫： Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h ambari-server3 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
[確定]
正在啓動 mysqld： [確定]
[root@ambari-server3 java]#
現在就可以測試這幾個命令了：
[root@ambari-server3 java]# chkconfig --list mysql
在 mysql 服務中讀取信息時出錯：沒有那個文件或目錄
[root@ambari-server3 java]# chkconfig --list mysqld
mysqld 0:關閉 1:關閉 2:關閉 3:關閉 4:關閉 5:關閉 6:關閉
[root@ambari-server3 java]# chkconfig --list | grep mysqld
mysqld 0:關閉 1:關閉 2:關閉 3:關閉 4:關閉 5:關閉 6:關閉
[root@ambari-server3 java]# chkconfig --list | grep mysql
mysqld 0:關閉 1:關閉 2:關閉 3:關閉 4:關閉 5:關閉 6:關閉
設置mysqld隨機啓動
[root@ambari-server3 java]# chkconfig mysqld on
[root@ambari-server3 java]# chkconfig --list | grep mysqld
mysqld 0:關閉 1:關閉 2:啓用 3:啓用 4:啓用 5:啓用 6:關閉
--------------------------------
[root@ambari-server3 java]# ps -ef | grep mysql
root 27394 1 0 12:40 pts/1 00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --socket=/var/lib/mysql/mysql.sock --pid-file=/var/run/mysqld/mysqld.pid --basedir=/usr --user=mysql
mysql 27496 27394 0 12:40 pts/1 00:00:00 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --log-error=/var/log/mysqld.log --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/lib/mysql/mysql.sock
root 27533 27081 0 12:45 pts/1 00:00:00 grep mysql
根據進程信息可以看到，mysql的數據庫data目錄是 /var/lib/mysql ，錯誤日誌文件是 /var/log/mysqld.log
---------------------------------
跟據上面啓動msyld服務時提供的設置管理員密碼方法：
[root@ambari-server3 java]# /usr/bin/mysqladmin -u root password '123456'
[root@ambari-server3 java]# mysql #因爲上面一步，我已經設置密碼了；
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
[root@ambari-server3 java]# mysql -uroot -p123456

下面開始搞ambari的安裝了：
1).安裝配置本地源需要的組件
yum install httpd
yum install yum-utils
yum repolist
yum install createrepo
[root@ambari-server3 ~]# yum install httpd -y
[root@ambari-server3 ~]# yum install yum-utils -y
[root@ambari-server3 ~]# yum repolist
已加載插件：fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirrors.zju.edu.cn
* extras: mirrors.zju.edu.cn
* updates: mirrors.zju.edu.cn
倉庫標識 倉庫名稱 狀態
base CentOS-6 - Base 6,706
extras CentOS-6 - Extras 47
updates CentOS-6 - Updates
[root@ambari-server3 ~]# yum install createrepo -y
2).直接使用命令：yum install httpd；安裝完成後，會生成 /var/www/html 目錄
在/var/www/html目錄下，分別建立ambari和hdp目錄:
[root@ambari-server3 html]# mkdir /var/www/html/ambari
[root@ambari-server3 html]# mkdir /var/www/html/hdp
[root@ambari-server3 source]# tar -xf ambari-2.4.1.0-centos6.tar.gz -C /var/www/html/ambari/
[root@ambari-server3 source]# tar -xf HDP-2.5.0.0-centos6-rpm.tar.gz -C /var/www/html/hdp/
啓動httpd服務：
[root@ambari-server3 yum.repos.d]# server httpd status
-bash: server: command not found
[root@ambari-server3 yum.repos.d]# service httpd status
httpd 已停
[root@ambari-server3 yum.repos.d]# service httpd start
正在啓動 httpd：httpd: Could not reliably determine the server's fully qualified domain name, using 192.168.182.132 for ServerName [確定]
設置httpd服務開機自動啓動：
[root@ambari-server3 yum.repos.d]# chkconfig httpd on
下載並修改ambrii.repo文件
[root@ambari-server3 yum.repos.d]# wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.4.1.0/ambari.repo -O/etc/yum.repos.d/ambari.repo

生成本地源
使用createrepo命令，生成本地源
[root@ambari-server3 hdp]# mkdir -p /var/www/html/hdp/HDP-UTILS-1.1.0.21/
[root@namenode1 ~]# mkdir -p/var/www/html/hdp/HDP/centos6/
#目錄有的話就不用創建了：
[root@ambari-server3 centos6]# createrepo /var/www/html/hdp/HDP/centos6/
[root@ambari-server3 centos6]# createrepo /var/www/html/hdp/HDP-UTILS-1.1.0.21/
關閉THP
在集羣的每個節點，都要關閉。編輯/etc/grub.conf文件，在kernel 行後面加入
transparent_hugepage=never，保存退出，重啓機器。
[root@ambari-server1 ~]# vim /etc/grub.conf
[root@ambari-server2 ~]# vim /etc/grub.conf
[root@ambari-server3 ~]# vim /etc/grub.conf
一個時間同步必須要做，：
主節點：
[root@ambari-server3 etc]# cp ntp.conf ntp.conf_bak_20180114
[root@ambari-server3 etc]# vim ntp.conf
[root@ambari-server3 etc]# service ntpd status
ntpd 已停
[root@ambari-server3 etc]# service ntpd start
