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

a.MySQL离线部署
b.CM离线部署
c.Parcel文件离线源部署

2.规划

3.下载源

• CM
  http://archive.cloudera.com/cm5/cm/5/cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz
• Parcel
  http://archive.cloudera.com/cdh5/parcels/5.16.1/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel
  http://archive.cloudera.com/cdh5/parcels/5.16.1/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha1
  http://archive.cloudera.com/cdh5/parcels/5.16.1/manifest.json

  mysql-connector-java.jar

准备好百度云,下载安装包:
链接:https://pan.baidu.com/s/10s-NaFLfztKuWImZTiBMjA 密码:viqp

二.集群节点初始化

1.阿里云华南区购买3台，按量付费虚拟机

CentOS7.2操作系统，2核8G最低配置
密码：Diamond8888

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:
47.112.166.64 hadoop001
47.112.157.186 hadoop002
47.112.150.172 hadoop003

3.设置所有节点的hosts文件

私有地址、内网地址:
echo "172.18.98.143 hadoop001">> /etc/hosts
echo "172.18.98.144 hadoop002">> /etc/hosts
echo "172.18.98.142 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

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

8.1.解压及创建目录

8.33.创建用户组及用户
[root@hadoop001 local]# groupadd -g 101 dba
[root@hadoop001 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@hadoop001 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)

## 一般不需要设置mysqladmin的密码，直接从root或者LDAP用户sudo切换
#[root@hadoop001 local]# passwd mysqladmin
Changing password for user mysqladmin.
New UNIX password: 123456
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password: 
passwd: all authentication tokens updated successfully.

## if user mysqladmin is existing,please execute the following command of usermod.
#[root@hadoop001 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

8.4.copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量
[root@hadoop001 local]# cp /etc/skel/.* /usr/local/mysql  
###important

8.5.配置环境变量
[root@hadoop001 local]# vi mysql/.bash_profile
# .bash_profile
# Get the aliases and functions

if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
export MYSQL_BASE=/usr/local/mysql
export PATH=${MYSQL_BASE}/bin:$PATH


unset USERNAME

#stty erase ^H
set umask to 022
umask 022
PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1

8.6.赋权限和用户组，切换用户mysqladmin，安装
[root@hadoop001 local]# chown  mysqladmin:dba /etc/my.cnf 
[root@hadoop001 local]# chmod  640 /etc/my.cnf  


[root@hadoop001 local]# chown -R mysqladmin:dba /usr/local/mysql
[root@hadoop001 local]# chmod -R 755 /usr/local/mysql

8.7.配置服务及开机自启动
[root@hadoop001 local]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@hadoop001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 
#赋予可执行权限
[root@hadoop001 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@hadoop001 mysql]# chkconfig --del mysql
#添加服务
[root@hadoop001 mysql]# chkconfig --add mysql
[root@hadoop001 mysql]# chkconfig --level 345 mysql on

8.8.安装libaio及安装mysql的初始db
[root@hadoop001 mysql]# yum -y install libaio
[root@hadoop001 mysql]# su - mysqladmin

hadoop001:mysqladmin:/usr/local/mysql:> bin/mysqld \
--defaults-file=/etc/my.cnf \
--user=mysqladmin \
--basedir=/usr/local/mysql/ \
--datadir=/usr/local/mysql/data/ \
--initialize

在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码的 root@localhost 账号，密码直接写在 log-error 日志文件中
（在5.6版本中是放在 ~/.mysql_secret 文件里，更加隐蔽，不熟悉的话可能会无所适从）

8.9.查看临时密码
hadoop001:mysqladmin:/usr/local/mysql/data:>cat hostname.err |grep password
2019-12-22T10:03:36.640568Z 1 [Note] A temporary password is generated for root@localhost: DjeuJCqdh9?7
hadoop001:mysqladmin:/usr/local/mysql/data:>

8.10.启动
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

8.11.登录及修改用户密码
hadoop001:mysqladmin:/usr/local/mysql:>mysql -uroot -p'DjeuJCqdh9?7'
mysql: [Warning] Using a password on the command line interface can be insecure.

[root@hadoop001 parcel-repo]# 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

[root@hadoop001 cdh5.16.1]# /opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-agent start
Starting cloudera-scm-agent:                               [  OK  ]
[root@hadoop002 cdh5.16.1]# /opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-agent start
Starting cloudera-scm-agent:                               [  OK  ]
[root@hadoop003 cdh5.16.1]# /opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-agent start
Starting cloudera-scm-agent:                               [  OK  ]

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

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

9.感谢您选择Cloudera Manager和CDH

10.为CDH集群安装指导主机。选择[当前管理理的主机]，全部勾选

11.选择存储库

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。

13.检查主机正确性

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：表示最⼤大限度使用物理理内存，之后才是swap空间；
swappiness=100：表示积极使⽤用swap分区，并且把内存上的数据及时搬迁到swap空间；
如果是混合服务器器，不不建议完全禁用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

15.自定义⻆角色分配

16.数据库设置

password: Ruozedata123456!

17.审改设置，默认即可

18.首次运行

19.恭喜您!
