一.部署Ambari Server端

二.时钟同步
我们在生产环境中必须同步各个服务器时间是一致的，最好是有内网的时间服务器。 配置时间同步的好处: 可以定位集群故障发生的具体时间; 解决HBase,Kudu等存储依赖于时间同步的问题(若时间不同步会报错); CentOS 6.x默认使用ntpd软件来同步时间的，但在CentOS 7.x版本之后就被更替为chrony来实现时间同步，因此咱们安装时间同步就是用CentOS 7.x推荐的Chrony来进行时间同步。
1>.安装chrony
[root@hdp101.yinzhengjie.org.cn ~]# yum -y install chrony Loaded plugins: fastestmirror Determining fastest mirrors * base: mirror.bit.edu.cn * extras: mirror.bit.edu.cn * updates: mirrors.huaweicloud.com ambari-repo | 2.9 kB 00:00:00 base | 3.6 kB 00:00:00 extras | 2.9 kB 00:00:00 mysql-connectors-community | 2.5 kB 00:00:00 mysql-tools-community | 2.5 kB 00:00:00 mysql80-community | 2.5 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/2): extras/7/x86_64/primary_db | 159 kB 00:00:00 (2/2): updates/7/x86_64/primary_db | 5.9 MB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package chrony.x86_64 0:3.4-1.el7 will be installed --> Processing Dependency: libseccomp.so.2()(64bit) for package: chrony-3.4-1.el7.x86_64 --> Running transaction check ---> Package libseccomp.x86_64 0:2.3.1-3.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================================================================================================================================================== Package Arch Version Repository Size ============================================================================================================================================================================================================================================================================== Installing: chrony x86_64 3.4-1.el7 base 251 k Installing for dependencies: libseccomp x86_64 2.3.1-3.el7 base 56 k Transaction Summary ============================================================================================================================================================================================================================================================================== Install 1 Package (+1 Dependent package) Total download size: 306 k Installed size: 788 k Downloading packages: (1/2): libseccomp-2.3.1-3.el7.x86_64.rpm | 56 kB 00:00:00 (2/2): chrony-3.4-1.el7.x86_64.rpm | 251 kB 00:00:00 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Total 957 kB/s | 306 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : libseccomp-2.3.1-3.el7.x86_64 1/2 Installing : chrony-3.4-1.el7.x86_64 2/2 Verifying : libseccomp-2.3.1-3.el7.x86_64 1/2 Verifying : chrony-3.4-1.el7.x86_64 2/2 Installed: chrony.x86_64 0:3.4-1.el7 Dependency Installed: libseccomp.x86_64 0:2.3.1-3.el7 Complete!

2>.禁用本地时间服务器从公网同步时间
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server 0.centos.pool.ntp.org iburst server 1.centos.pool.ntp.org iburst server 2.centos.pool.ntp.org iburst server 3.centos.pool.ntp.org iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# sed -r -i 's@(^server)@#1@g' /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]#
3>.新增时间同步服务器为本机地址
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# vim /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
4>.设置允许来chronyd服务器端同步时间的客户端地址
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# grep ^#allow /etc/chrony.conf #allow 192.168.0.0/16 [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# sed -r -i 's@#(allow) 192.168.0.0/16@1 172.200.0.0/21@' /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# vim /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync allow 172.200.0.0/21 #允许客户端IP地址同步 allow 127/8 #允许本地同步时间 logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
5>.设置chronyd服务器端允许返回本地时间
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync allow 172.200.0.0/21 allow 127/8 logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# grep ^#local /etc/chrony.conf #local stratum 10 [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# sed -r -i 's@#(local)@1@' /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync allow 172.200.0.0/21 allow 127/8 local stratum 10 #即使自己未能通过网络时间服务器同步到时间，也允许将本地时间作为标准时间授时给其它客户端，而我们上面设置了禁用默认公网的时间服务器进行同步(换句话说，这里表示不去同步任何服务器的时间)。 logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
6>.启动chronyd并设置为开机自启动
[root@hdp101.yinzhengjie.org.cn ~]# systemctl start chronyd [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# systemctl enable chronyd [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# systemctl list-unit-files | grep chronyd chronyd.service enabled [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
7>.查看chronyd正在使用哪个时间服务器进行时间同步

三.部署Ambari集群
1>.浏览器访问"http://hdp101.yinzhengjie.org.cn:8080/",使用默认的用户名(admin)和密码(admin)登录成功后启动安装向导(如下图所示,点击"LAUNCH INSTALL WIZARD")
2>.自定义集群名称，并点击下一步
3>.选择HDP版本，并选择本地软件源仓库
4>.删除不相关操作系统的仓库信息，只保留部署Ambari的操作系统的仓库信息
5>.注册主机
6>.确认匹配的主机名称
7>.等待自动注册
8>.等待集群自检
9>.集群自检完成
如果此步骤和上图一样直接跳过下面的阅读，如果你安装其它节点存在问题，如下图所示，别慌，查看日志解决问题才是正道。
查看报错信息，如下图所示。
根据报错信息将hdp101.yinzhengjie.org.cn与hdp[102-103].yinzhengjie.org.cn不同的文件同步后，之前两个失败的节点最终状态变为"Success"状态。
10>.查看集群自建结果(此步骤可省略，直接进行下一步)
11>.自定义需要安装的服务(服务勾选少了也没多大关系,后面可以手动添加服务)
12>.勾选Ambari Metircs(会自动安装监控已经勾选服务的状态)服务并点击"NEXT",如果弹出如下图所示的提示，点击"PROCEED ANYWAY"
13>.根据服务器实际资源分配Master服务角色安装到具体的主机
14>.除了NFSGateway角色(如有需要后续可以自行安装)不勾选，其它的slave服务都勾选
15>.为Grafana Admin和Activity Explorer's Admin服务设置密码
16>.自定义各个服务对应数据的存储路径(由于我们使用的是root用户安装，因此尽管指定的目录不存在，Ambari会通过root用户自动创建的哟~)
17>.确认各个服务在操作系统中以哪个用户身份运行(保持默认即可，直接下一步)
18>.自定义安装服务的配置并点击下一步
19>.在Review步骤无需做任何配置，而是对之前几个步骤的配置有一个大概的信息概览，如果确认配置五五后点击"DEPLOY"就正式部署啦
20>.点击"DEPLOY"会开始初始化任务
21>.初始化完就开始部署了
22>.等待服务自动安装,启动和测试
23>.服务安装成功
24>.安装完成后点击上图的“COMPLETE”会自动进入到"Dashboard"的监控页面
25>.手动测试HDFS服务是否安装成功
