[转]CDH5.16.1集群企业真正离线部署

一.准备工作
1.离线部署主要分为三块:

• MySQL离线部署
• CM离线部署
• Parcel文件离线源部署

2、规划

节点	MySQL部署组件	Parcel文件离线源	CM服务进程	大数据组件
hadoop001	MySQL	Parcel	Activity Monitor	NN RM DN NM
hadoop002			Alert Publisher Event Server	DN NM
hadoop003			Host MonitorService Monitor	DN NM

3.下载源:
地址：http://archive.cloudera.com/cdh5/

• CM
  cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz

• Parcel
  CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel
  CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha1
  manifest.json

• JDK
  https://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html
  下载jdk-8u202-linux-x64.tar.gz

• MySQL
  https://dev.mysql.com/downloads/mysql/5.7.html#downloads
  下载mysql-5.7.26-el7-x86_64.tar.gz

• MySQL jdbc jar
  mysql-connector-java-5.1.47.jar
  下载完成后要重命名去掉版本号，
  mv mysql-connector-java-5.1.47.jar mysql-connector-java.jar

二.集群节点初始化
1.阿里云上海区购买3台，按量付费虚拟机
CentOS7.2操作系统，2核8G最低配置

2.当前笔记本或台式机配置hosts文件
MAC: /etc/hosts
Window: C:\windows\system32\drivers\etc\hosts

公网地址:

106.15.234.222 hadoop001  
106.15.235.200 hadoop002  
106.15.234.239 hadoop003  

3.设置所有节点的hosts文件
私有地址、内网地址:

echo "172.19.7.96 hadoop001">> /etc/hosts
echo "172.19.7.98 hadoop002">> /etc/hosts
echo "172.19.7.97 hadoop003">> /etc/hosts

4.关闭所有节点的防火墙及清空规则

systemctl stop firewalld 
systemctl disable firewalld
iptables -F

5.关闭所有节点的selinux

vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled 
设置后需要重启才能生效

6.设置所有节点的时区一致及时钟同步

1[root@hadoop001 ~]# date

time

server 0.asia.pool.ntp.org
server 1.asia.pool.ntp.org
server 2.asia.pool.ntp.org
server 3.asia.pool.ntp.org

当外部时间不可用时，可使用本地硬件时间

server 127.127.1.0 iburst local clock 

允许哪些网段的机器来同步时间

restrict 172.19.7.0 mask 255.255.255.0 nomodify notrap

开启ntpd及查看状态

 [root@hadoop001 ~]# systemctl start ntpd
 [root@hadoop001 ~]# systemctl status ntpd

7.部署集群的JDK

mkdir /usr/java
tar -xzvf jdk-8u45-linux-x64.tar.gz -C /usr/java/
#切记必须修正所属用户及用户组
chown -R root:root /usr/java/jdk1.8.0_45
echo "export JAVA_HOME=/usr/java/jdk1.8.0_45" >> /etc/profile
echo "export PATH=${JAVA_HOME}/bin:${PATH}" >> /etc/profile
source /etc/profile
which java

8.hadoop001节点离线部署MySQL5.7

9.创建CDH的元数据库和用户、amon服务的数据库及用户

create database cmf DEFAULT CHARACTER SET utf8;
create database amon DEFAULT CHARACTER SET utf8;
grant all on cmf.* TO 'cmf'@'%' IDENTIFIED BY 'Ruozedata123456!';
grant all on amon.* TO 'amon'@'%' IDENTIFIED BY 'Ruozedata123456!';
flush privileges;

10.hadoop001节点部署mysql jdbc jar

mkdir -p /usr/share/java/
cp mysql-connector-java.jar /usr/share/java/

三.CDH部署
1.离线部署cm server及agent

1.1.所有节点创建目录及解压
mkdir /opt/cloudera-manager
tar -zxvf cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz -C /opt/cloudera-manager/
1.2.所有节点修改agent的配置，指向server的节点hadoop001
sed -i "s/server_host=localhost/server_host=hadoop001/g" /opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-agent/config.ini
1.3.主节点修改server的配置:
vi /opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-server/db.properties 
com.cloudera.cmf.db.type=mysql
com.cloudera.cmf.db.host=hadoop001
com.cloudera.cmf.db.name=cmf
com.cloudera.cmf.db.user=cmf
com.cloudera.cmf.db.password=Ruozedata123456!
com.cloudera.cmf.db.setupType=EXTERNAL
1.4.所有节点创建用户
useradd --system --home=/opt/cloudera-manager/cm-5.16.1/run/cloudera-scm-server/ --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
1.5.目录修改用户及用户组
chown -R cloudera-scm:cloudera-scm /opt/cloudera-manager

2.hadoop001节点部署离线parcel源

2.1.部署离线parcel源
$ mkdir -p /opt/cloudera/parcel-repo
$ ll
total 3081664
-rw-r--r-- 1 root root 2127506677 May  9 18:04 CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel
-rw-r--r-- 1 root root         41 May  9 18:03 CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha1
-rw-r--r-- 1 root root  841524318 May  9 18:03 cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz
-rw-r--r-- 1 root root  185515842 Aug 10  2017 jdk-8u144-linux-x64.tar.gz
-rw-r--r-- 1 root root      66538 May  9 18:03 manifest.json
-rw-r--r-- 1 root root     989495 May 25  2017 mysql-connector-java.jar
$ cp CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel /opt/cloudera/parcel-repo/
#切记cp时，重命名去掉1，不然在部署过程CM认为如上文件下载未完整，会持续下载
$ cp CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha1 /opt/cloudera/parcel-repo/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha
$ cp manifest.json /opt/cloudera/parcel-repo/
2.2.目录修改用户及用户组
$ chown -R cloudera-scm:cloudera-scm /opt/cloudera/ 

3.所有节点创建软件安装目录、用户及用户组权限

mkdir -p /opt/cloudera/parcels
chown -R cloudera-scm:cloudera-scm /opt/cloudera/

4.hadoop001节点启动Server

4.1.启动server
/opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-server start
4.2.阿里云web界面，设置该hadoop001节点防火墙放开7180端口
4.3.等待1min，打开 http://hadoop001:7180 账号密码:admin/admin
4.4.假如打不开，去看server的log，根据错误仔细排查错误

5.所有节点启动Agent

/opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-agent start

6.接下来，全部Web界面操作
http://hadoop001:7180/
账号密码:admin/admin

7.欢迎使用Cloudera Manager--最终用户许可条款与条件。勾选

image.png

8.欢迎使用Cloudera Manager--您想要部署哪个版本？选择Cloudera Express免费版本

image.png

9.感谢您选择Cloudera Manager和CDH

image.png

10.为CDH集群安装指导主机。选择[当前管理的主机]，全部勾选

image.png

11.选择存储库

image.png

12.集群安装--正在安装选定Parcel
假如本地parcel离线源配置正确，则"下载"阶段瞬间完成，其余阶段视节点数与内部网络情况决定

image.png

13.检查主机正确性

image.png

13.1.建议将/proc/sys/vm/swappiness设置为最大值10。
swappiness值控制操作系统尝试交换内存的积极；
swappiness=0：表示最大限度使用物理内存，之后才是swap空间；
swappiness=100：表示积极使用swap分区，并且把内存上的数据及时搬迁到swap空间；
如果是混合服务器，不建议完全禁用swap，可以尝试降低swappiness。
临时调整：
sysctl vm.swappiness=10
永久调整：
cat << EOF >> /etc/sysctl.conf
# Adjust swappiness value
vm.swappiness=10
EOF
13.2.已启用透明大页面压缩，可能会导致重大性能问题，建议禁用此设置。
临时调整：
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
永久调整：
cat << EOF >> /etc/rc.d/rc.local
# Disable transparent_hugepage
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
EOF
# centos7.x系统，需要为"/etc/rc.d/rc.local"文件赋予执行权限
chmod +x /etc/rc.d/rc.local

14.自定义服务，选择部署Zookeeper、HDFS、Yarn服务

image.png

15.自定义角色分配

image.png

16.数据库设置

image.png

17.审改设置，默认即可

image.png

18.首次运行

19.恭喜您!
