1.系统版本
[root@manager ~]# cat /etc/centos-release CentOS Linux release 7.4.1708 (Core)
2.主机规划
| 主机名 | IP地址 | 角色 |
| manager | 192.168.10.131 | ambari-server |
| vm1 | 192.168.10.128 | agent |
| vm2 | 192.168.10.129 | agent |
| vm3 | 192.168.10.130 | agent |
3.软件版本
ambari-2.4.3.0-centos7.tar.gz HDP-2.5.3.0-centos7-rpm.tar.gz HDP-UTILS-1.1.0.21-centos7.tar.gz
二、环境准备（所有节点上都要配置）
1.修改主机名
2.防火墙和selinux
[root@manager ~]# systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:firewalld(1) [root@manager ~]# getenforce Disabled [root@manager ~]#
3.配置hosts文件
[root@manager ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.10.128 vm1 192.168.10.129 vm2 192.168.10.130 vm3 192.168.10.131 manager
4.配置SSH免密码登陆
5.关闭linux的THP服务
#在GRUB_CMDLINE_LINUX这一行后面添加transparent_hugepage=never，如下 [root@manager ~]# cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never" GRUB_DISABLE_RECOVERY="true" #执行以下命令 [root@manager ~]# grub2-mkconfig -o /boot/grub2/grub.cfg [root@manager ~]# systemctl disable tuned #重启后显示如下 [root@manager ~]# cat /sys/kernel/mm/transparent_hugepage/enabled always madvise [never] [root@manager ~]# grep AnonHugePages /proc/meminfo AnonHugePages: 0 kB [root@manager ~]#
6.配置UMASK
[root@manager ~]# umask 0022 [root@manager ~]# umask 0022
7.配置时间同步NTP
[root@manager ~]# yum -y install ntp [root@manager ~]# systemctl start ntpd [root@manager ~]# systemctl enable ntpd
8.安装JDK并配置JAVA_HOME环境变量
三、安装Ambari集群（只在manager上配置)
1.安装HTTP服务
[root@manager ~]# yum install -y httpd [root@manager ~]# systemctl start httpd [root@manager ~]# systemctl enable httpd
2.安装MySQL
3.配置MySQL
#mysql有密码复杂度要求，如果不需要密码策略在/etc/my.cnf文件中添加如下配置并重启mysql即可禁用 validate_password = off systemctl restart mysqld #查看mysql的初始默认密码 [root@manager ~]# cat /var/log/mysqld.log | grep password 2017-12-13T01:49:55.629403Z 1 [Note] A temporary password is generated for root@localhost: 3aYp&Zsqq7Ov #使用初始密码进入mysql修改密码 ALTER USER 'root'@'localhost' IDENTIFIED BY '123456'; #在mysql中创建ambari数据库及用户 CREATE DATABASE ambari CHARACTER SET utf8 ; CREATE USER 'ambari'@'%'IDENTIFIED BY '123456'; CREATE USER 'ambari'@'local'IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%'; FLUSH PRIVILEGES; #创建hive和其它数据库也类似
4.下载Ambari和HDP
wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.3.0/ambari-2.4.3.0-centos7.tar.gz wget -nv http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.3.0/HDP-2.5.3.0-centos7-rpm.tar.gz wget -nv http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.21-centos7.tar.gz
5.解压至httpd目录下
[root@manager ~]# mkdir /var/www/html/ambari [root@manager ~]# mkdir /var/www/html/ambari/HDP-UTILS tar zxvf ambari-2.4.3.0-centos7.tar.gz -C /var/www/html/ambari tar zxvf HDP-2.5.3.0-centos7-rpm.tar.gz -C /var/www/htmlambari tar zxvf HDP-UTILS-1.1.0.21-centos7.tar.gz -C /var/www/html/ambari/HDP-UTILS
6.安装本地源制作相关工具
[root@manager ~]# yum install -y yum-utils createrepo yum-plugin-priorities [root@manager ~]# vim /etc/yum/pluginconf.d/priorities.conf [main] enabled = 1 gpgcheck=0 [root@manager data]# cd /var/www/html/ambari [root@manager ambari]# createrepo ./
7.配置本地源
[root@manager ~]# cat /etc/yum.repos.d/ambari.repo [ambari-2.4.3.0] name=ambari-2.4.3.0 baseurl=http://manager/ambari/AMBARI/ gpgcheck=1 gpgkey=http://manager/ambari/AMBARI/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins enabled=1 priority=1 [root@manager ~]# cat /etc/yum.repos.d/hdp.repo [HDP-2.5.3.0] name=HDP baseurl=http://manager/ambari/HDP/centos7/ gpgcheck=1 gpgkey=http://manager/ambari/HDP/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins enabled=1 priority=1 [HDP-UTILS-1.1.0.21] name=HDP-UTILS baseurl=http://manager/ambari/HDP-UTILS/ gpgcheck=1 gpgkey=http://manager/ambari/HDP-UTILS/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins enabled=1 priority=1
[root@manager ~]# yum clean all [root@manager ~]# yum makecache #查看ambari和hdp的资源库 [root@manager ~]# yum repolist repo id repo name status HDP-2.5.3.0 HDP 200 HDP-UTILS-1.1.0.21 HDP-UTILS 64 ambari-2.4.3.0 ambari-2.4.3.0
8.安装ambari和mysql驱动
[root@manager ~]# yum install -y ambari [root@manager ~]# yum install -y mysql-connector-java
9.配置ambari
[root@manager ~]# ambari-server setup Using python /usr/bin/python Setup ambari-server Checking SELinux...

10.使用msyql用户ambari在ambari数据库中导入数据
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
11.启动ambari
[root@manager ~]# ambari-server start #在浏览器中输入ambari地址 http://192.168.10.131:8080
