Cloudera-manager(CDH6.3.0)大数据平台搭建一指禅指南(impala,kudu,hdfs,hive,kafka,yarn,spark,hbase,hue)
CHD6，大量hadoop生态的重大更新升级，果断把现有系统升级到CHD6上。
准备：
192.168.88.31 master--》机器名修改为:manager 还是重复的master把
192.168.88.32 utility
192.168.88.33 gateway
192.168.88.34 worker1
每台虚拟机8g内存（不想给自己找麻烦，就搞8G内存，否则会卡主各种莫名其妙的问题的）,建议最低4台测试。3台虚拟机也是可以安装环境的。
[root@manager ~]# vi /etc/sysconfig/network
HOSTNAME=master
# [root@manager ~]# vi /etc/hosts
127.0.0.1 localhost manager localhost4 localhost4.localdomain4 （需要删除）
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 （需要删除）
//永久性的修改主机名称，重启后能保持修改后的。
[root@manager ~]# hostnamectl set-hostname master
[root@manager ~]# cat /etc/hostname
[root@manager ~]# reboot
[root@manager ~]# hostname
manager
设置静态IP、DNS、网关
[hadoop@utility ~]$ sudo vi /etc/sysconfig/network-scripts/ifcfg-ens33
#BOOTPROTO=dhcp
BOOTPROTO=static #设置网卡获得ip地址的方式，可能的选项为static，dhcp或bootp，分别对应静态指定的 ip地址，通过dhcp协议获得的ip地址，通过bootp协议获得的ip地址
IPADDR=192.168.88.31 #如果设置网卡获得 ip地址的方式为静态指定，此字段就指定了网卡对应的ip地址
NETMASK=255.255.255.0 #网卡对应的网络掩码
NETWORK=192.168.88.0 #网卡对应的网络地址
GATEWAY=192.168.88.2 #有时候叫做default route address
DNS1=192.168.88.2
[hadoop@utility ~]$ sudo service network restart
[hadoop@utility ~]$ sudo ifconfig -a
[hadoop@utility ~]$ sudo nslookup www.baidu.com
[hadoop@utility ~]$ sudo nmcli con mod ens33 ipv4.dns "192.168.88.2"
[hadoop@utility ~]$ sudo nmcli con up ens33
[hadoop@utility ~]$ cat /etc/resolv.conf
给每台机器的hadoop用户添加sudo免密码的功能
[root@localhost ~]# vi /etc/sudoers
添加如下的声明:
hadoop ALL=(ALL) NOPASSWD: ALL
[hadoop@manager ~]$ sudo yum install -y vim wget ntp net-tools
给每台机器都增加hosts文件的配置,修改完成后，相互之间可以ping通
[hadoop@manager ~]$ sudo vi /etc/hosts
192.168.88.31 master
192.168.88.32 utility
192.168.88.33 gateway
192.168.88.34 worker1
在这里有个坑需要注意的，以前初始的hosts文件中是有
127.0.0.1 localhost manager localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
的，这个是需要删除的，否则后面安装报错。
[hadoop@manager ~]$ ping master
[hadoop@manager ~]$ ping www.baidu.com
每台主机关闭防火墙（折行写的命令最后不能有空格，否则报错）
[hadoop@manager ~]$
sudo systemctl stop firewalld \
&& sudo systemctl disable firewalld \
&& sudo systemctl status firewalld
每台机器关闭selinux
[hadoop@manager ~]$ sudo setenforce 0
[hadoop@manager ~]$ sudo vim /etc/selinux/config
SELINUX=permissive
[hadoop@manager ~]$ getenforce
Permissive
每台机器配置NTP服务
[hadoop@manager ~]$ sudo vim /etc/ntp.conf
#将时钟服务器更改为如下4个
server 0.cn.pool.ntp.org
server 1.cn.pool.ntp.org
server 2.cn.pool.ntp.org
server 3.cn.pool.ntp.org
[hadoop@manager ~]$
sudo systemctl start ntpd \
&& sudo systemctl enable ntpd \
&& sudo ntpdate -u 0.cn.pool.ntp.org \
&& sudo hwclock --systohc \
&& sudo date
在tools主机上安装（生产环境，减轻master的负担，不过在我本机开发，都是用的master，所以这里我用master进行安装）

According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

启动CM
[root@manager ~]#
systemctl stop cloudera-scm-server \
&& systemctl start cloudera-scm-server \
&& sleep 2 \
&& tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log | grep "INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server"
1分钟等待后，如果出现：
2019-10-31 00:39:00,113 INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server.
则代表CM启动成功了
访问---》【http://192.168.88.31:7180】
账号密码为admin/admin
在整个启动过程中，可以新开一个窗口，然后tail -f看看日志有啥错误
[root@manager ~]# tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
如果在中间出现问题，要先
[root@manager ~]# systemctl stop cloudera-scm-server
再运行上面的启动命令。数据库密码【123456Aa.】
初始化CM
如果在中间报异常了，那么基本上就需要做回滚和清理动作了（还不如重新来个新的操作系统来得简单）
【一】、Cluster Basics
给个人看得懂的集群名字即可
【二】、Accept JDK License
接受，不接受走不下去
【三】、Enter Login Credentials
root用户可以安装（sudo用户？？？？）安装 Cloudera 包需要有主机的 root 访问权限。此安装程序将通过 SSH 连接到您的主机，然后直接以 root 用户身份登录，或者以另一个具有变为 root 用户的无密码 sudo/pbrun 权限的用户身份登录。
【四】、Specify Hosts
192.168.88.[31-34]，可以通过这样的表达式来搜索多台机器
【五】、Select Repository
填入本地的yum库---》http://192.168.88.31/cloudera-manager/
CDH-6.3.0-1.cdh6.3.0.p0.1279813，这里我们需要明确我们自己安装的版本，因为系统会把比较新的版本都显示出来，如果选择错了，就是从网络下载了，那个时间就超长了
【六】、Install Agents
耗时10、20分钟的样子，由于页面是js写的，因此不要刷新浏览器。如果出错了，根据错误修正接节点的问题，然后retry。如果我们在这里放弃了，基本上这个操作系统也就废掉了（删除清理，估计也是非常麻烦的）
【七】、Install Parcels
耗时几个小时，distubuted哪里会刷新传递分发的速度 xxM/s。这个阶段磁盘占用率非常高。页面上是有简单的进度条显示整体进度的。没有到100%，continue的按钮是点击不了的。
【八】、Inspect Cluster
点击Inspect Network Performance按钮
点击Inspect Hosts按钮，可以参考这里：https://blog.****.net/qq_39680564/article/details/100013275，相关的报错汇总
主机健康检查、I understand the risks, let me continue with cluster setup.，点选这个走下去。
各个组件的验证
【选择安装的服务】
impala、hdfs、hbase等组件
【自行分配角色至主机】
这里官方文档中，有按照规模建议指定机器的分配方式
【测试数据库链接】
这里的数据库实例名，用户名、密码都是上面的脚本创建的，这里是直接使用已经创建好的库，不能乱填的，要按照上面的创建mysql库的脚本来进行填写。
常见报错1：JDBC driver cannot be found. Unable to find the JDBC database jar on host
[hadoop@manager mysql-jdbc]$
sudo mkdir -p /usr/share/java/ \

常见报错2:Cloudera 建议将 /proc/sys/vm/swappiness 设置为最大值 10
临时生效：
sysctl vm.swappiness=10 && cat /proc/sys/vm/swappiness
echo 'vm.swappiness=10'>> /etc/sysctl.conf
永久生效：
echo 'vm.swappiness=10'>> /etc/sysctl.conf
常见报错3:已启用透明大页面压缩，可能会导致重大性能问题。
临时生效：

echo 'echo never > /sys/kernel/mm/transparent_hugepage/defrag' >> /etc/rc.local

https://blog.****.net/sardtass/article/details/93723610
来进行问题解决。解决后，不停重试安装即可。
【安装完成成功提示】
关闭所有服务：
在页面Cluster集群的cluster1后面有个下拉三角，点击出下拉列表后，点击stop，这个stop也就是把集群中的所有服务，全部定制
在Cloudera Management Service后面有个下拉三角，点击出下拉列表后，点击stop，这个stop也就是把集群中的所有服务，全部定制
仅仅在主机上运行
[root@master cloudera]# service cloudera-scm-server stop
Redirecting to /bin/systemctl stop cloudera-scm-server.service
每台机器都要运行这个指令
[root@master cloudera]# service cloudera-scm-agent stop
Redirecting to /bin/systemctl stop cloudera-scm-agent.service
[root@manager ~]#
service cloudera-scm-server stop \
&& service cloudera-scm-agent stop
重新启动整个集群:
service cloudera-scm-server start
所有都需要运行service cloudera-scm-agent start
先需要启动CM
[root@manager ~]#
systemctl stop cloudera-scm-server \
&& systemctl start cloudera-scm-server \
&& sleep 2 \
&& tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log | grep "INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server"
[root@manager ~]#
service cloudera-scm-server restart \
&& service cloudera-scm-agent restart
在Cloudera Management Service后面有个下拉三角，点击出下拉列表后，点击stop，这个start也就是把集群中的所有服务，全部定制
在页面Cluster集群的cluster1后面有个下拉三角，点击出下拉列表后，点击stop，这个start也就是把集群中的所有服务，全部定制
service cloudera-scm-server status
service cloudera-scm-agent status
[root@manager ~]#
