CDH5.16.1集群企业真正离线部署

⼀.准备⼯作

1.离线部署大纲

  • MySQL离线部署
  • CM离线部署
  • Parcel⽂件离线源部署

2.规划

linux版本:CentOS 7.2

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

3.下载源

  • CM
    cloudera-manager-centos7-cm5.16.1x8664.tar.gz

  • Parcel
    CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel
    CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel.sha1
    manifest.json

  • JDK
    JDK8
    下载jdk-8u202-linux-x64.tar.gz

  • MySQL
    MYSQL5.7
    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.阿里云购买3台虚拟机

(最低配置 2core 8G),选择按量付费

CentOS7.2

2.当前笔记本(win)hosts配置文件

路径: C:\Windows\System32\drivers\etc\hosts

39.97.188.249   hadoop001   hadoop001
39.97.225.112   hadoop002   hadoop002
39.97.224.68    hadoop003   hadoop003

注意:IP是你虚拟机公网IP

3.设置所有节点的hosts文件

echo '172.17.144.104 hadoop001' >> /etc/hosts
echo '172.17.144.103 hadoop002' >> /etc/hosts
echo '172.17.144.105 hadoop003' >> /etc/hosts
#检查
cat /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.17.144.104 hadoop001
172.17.144.103 hadoop002
172.17.144.105 hadoop003

注意:IP为内网IP

4.关闭所有节点防火墙及清空规则

云主机

我们使用的云主机,无论阿里云还是腾讯云的防火墙都是关闭的,所以我们不需要关闭服务器的防火墙。但是,我们需要检查下是否自动开启了web访问端口,如果没有,则自己添加

(1)打开安全组配置

CDH5.16.1集群企业真正离线部署

进入之后点击配置规则

(2)添加安全组规则

CDH5.16.1集群企业真正离线部署

注意:

1.点击蓝色感叹号会有规则说明

2.授权对象如果在公司内需要设置网段,就按照上图,将ip网段规定好。不限制的话就直接0.0.0.0/0

内网服务器

最好在内部服务器部署时就将防火墙关闭,如果不行就暂时关闭,等部署成功再开启

systemctl stop firewalld
systemctl disable firewalld
iptables -F   

5.关闭所有节点selinux

阿里云服务器已经将selinux关闭了,所以不用配置

自己的服务器很可能会开启selinux,这样就需要关闭了

将SELINUX=disabled设置进去,之后重启才会生效

vim /etc/selinux/config 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

6.设置所有节点时区一致及时钟同步

阿里云已经将节点时区和时间做了同步

我们实操下公司环境的时区时间同步

6.1时区

7.JDK部署

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
[root@hadoop001 cdh6.16.1]# vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_45
export PATH=${JAVA_HOME}/bin:${PATH}
source /etc/profile
which java

如果节点过多,那么就只做一台镜像模板,将基础工作完成之后,分发克隆。。(最好请运维小哥哥做~)

8.hadoop001节点离线部署MySQL5.7

(按照生产标准)

8.1 解压及创建文件夹

#解压
[root@hadoop001 cdh6.16.1]# tar xzvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
#切换目录
[root@hadoop001 cdh6.16.1]# cd /usr/local/
#修改mysql名称
[root@hadoop001 local]# mv mysql-5.7.11-linux-glibc2.5-x86_64/ mysql
#创建文件夹
[root@hadoop001 local]# mkdir mysql/arch mysql/data mysql/tmp

8.2 创建my.cnf

8.3 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

8.4 copy 环境变量配置文件

copy 环境变量配置文件(隐藏文件)至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量

cp /etc/skel/.* /usr/local/mysql  

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
Last login: Tue May 28 17:04:49 CST 2019 on pts/0
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

#查看密码
hadoop001:mysqladmin:/usr/local/mysql/data:>cat hostname.err |grep password
2019-05-28T09:28:40.447701Z 1 [Note] A temporary password is generated for root@localhost: J=

8.10 启动

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'ruozedata123' ;
#刷权限
mysql> flush privileges;

8.12 重启

9.创建CDH的元数据库和用户、 amon服务的数据库及用户

mysql> CREATE DATABASE `cmf`  DEFAULT CHARACTER SET utf8;
mysql> GRANT ALL PRIVILEGES ON cmf.* TO 'cmf'@'%' IDENTIFIED BY 'ruozedata123' ;
mysql> create database amon default character set utf8;
mysql> GRANT ALL PRIVILEGES ON amon.* TO 'amon'@'%' IDENTIFIED BY 'ruozedata123' ;
--刷权限
mysql> flush privileges;

10.部署 mysql JDBC jar

[root@hadoop001 cdh6.16.1]# mkdir -p /usr/share/java
[root@hadoop001 cdh6.16.1]# ls -lh
total 3.5G
-rw-r--r-- 1 root root 2.0G May 15 10:01 CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel
-rw-r--r-- 1 root root   41 May 14 20:17 CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel.sha1
-rw-r--r-- 1 root root 803M May 15 09:38 cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz
-rw-r--r-- 1 root root 166M May 14 20:21 jdk-8u45-linux-x64.gz
-rw-r--r-- 1 root root  65K May 14 20:17 manifest.json
-rw-r--r-- 1 root root 523M May 15 09:28 mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
-rw-r--r-- 1 root root 984K May 15 09:10 mysql-connector-java-5.1.47.jar
#mysql的jar包一定要去掉版本号~,有坑
[root@hadoop001 cdh6.16.1]# cp mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar

三.CDH离线部署

1.部署CM Server 和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
/
sed -i "s/server_host=localhost/server_host=hadoop001/g" /opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-agent/config.ini

1.2 所有节点修改config.ini

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=ruozedata123
com.cloudera.cmf.db.setupType=EXTERNAL

1.4 所有节点创建cloudera-scm用户

#创建cloudera-scm
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
#修改cloudera-manager的权限
chown -R cloudera-scm:cloudera-scm /opt/cloudera-manager

1.5 所有节点修改cloudera-manager用户名用户组

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
[root@hadoop001 opt]# cd ~/cdh6.16.1/
[root@hadoop001 cdh6.16.1]# ls -lh
total 3.5G
-rw-r--r-- 1 root root 2.0G May 15 10:01 CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel
-rw-r--r-- 1 root root   41 May 14 20:17 CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel.sha1
-rw-r--r-- 1 root root 803M May 15 09:38 cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz
-rw-r--r-- 1 root root 166M May 14 20:21 jdk-8u45-linux-x64.gz
-rw-r--r-- 1 root root  65K May 14 20:17 manifest.json
-rw-r--r-- 1 root root 523M May 15 09:28 mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
-rw-r--r-- 1 root root 984K May 15 09:10 mysql-connector-java-5.1.47.jar
[root@hadoop001 cdh6.16.1]# mv CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel.sha1 /opt/cloudera/parcel-repo/CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel.sha

#切记mv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
[root@hadoop001 cdh6.16.1]# mv CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel /opt/cloudera/parcel-repo/
[root@hadoop001 cdh6.16.1]# mv manifest.json  /opt/cloudera/parcel-repo/

如果你是通过网络下载的parcel包,我们就需要对CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel 进行校验,防止文件损坏!!!

[root@hadoop001 parcel-repo]# cat CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel.sha

#相同,可以正常使用

2.2 目录修改用户及用户组

chown -R cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo/

3.所有节点创建大数据软件安装目录、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 
    log路径在/opt/cloudera-manager/cm-5.16.1/log/cloudera-scm-server

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

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.已启⽤透明⼤⻚⾯压缩,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

CDH5.16.1集群企业真正离线部署

15.自定义角色分配

CDH5.16.1集群企业真正离线部署

16.数据库设置

CDH5.16.1集群企业真正离线部署

连接测试失败的可能原因:
(1)mysql JDBC jar包没有放到/usr/share/java或jar包没有去掉版本号
(2)建数据库cmf 和amon的时候,没有将权限设置成%
(3)设置完权限之后,没有flush privileges;

17.审改设置,默认即可

CDH5.16.1集群企业真正离线部署

18.⾸次运⾏

CDH5.16.1集群企业真正离线部署

19.恭喜您!

四.报错

1.在数据库设置测试时发生报错

报错信息

ERROR 226616765@scm-web-17:com.cloudera.server.web.common.JsonResponse:
JsonResponse created with throwable: com.cloudera.server.web.cmf.MessageException:
A package was not selected.

CDH5.16.1集群企业真正离线部署
原因:
测试连接时,等待时间过长,我就点了返回键重新加载,然后出现packet找不到的异常。
解决:
返回到选择大数据组件的页面后,重新进行操作,就可以测试成功了。
