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

创新互联公司是一家专业提供李沧企业网站建设,专注与网站制作、做网站、成都h5网站建设、小程序制作等业务。10年已为李沧众多企业、政府机构等服务。创新互联专业网络公司优惠进行中。

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

[root@hadoop001 ~]# timedatectl

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

rm /etc/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=<z#diyC4fh

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 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
703728dfa7690861ecd3a9bcd412b04ac8de7148
#计算下载文件的值，进行对比
[root@hadoop001 parcel-repo]# sha1sum CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel
703728dfa7690861ecd3a9bcd412b04ac8de7148  CDH-5.16.1-1.cdh6.16.1.p0.3-el7.parcel
#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

13.检查主机正确性

CDH5.16.1集群企业真正离线部署

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

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。
