### 离线安装Cloudera Manager 5.11.1和CDH5.11.1完全教程 ###

**关于CDH和Cloudera Manager**

CDH (Cloudera's Distribution, including Apache Hadoop)，是Hadoop众多分支中的一种，由Cloudera维护，基于稳定版本的Apache Hadoop构建，并集成了很多补丁，可直接用于生产环境。

Cloudera Manager则是为了便于在集群中进行Hadoop等大数据处理相关的服务安装和监控管理的组件，对集群中主机、Hadoop、Hive、Spark等服务的安装配置管理做了极大简化。

**安装前准备**  
**操作系统**：CentOS7.3 x64 GNOME DESTOP + development tools组包  
**Cloudera Manager**：5.12.0  
**CDH**: 5.12.0

**开发工具:**

secureCRT:远程登录 ,  可以同时将命令发送到多个节点上运行, 登录虚拟机操作简单

winscp:文件传输

**安装说明**  
官方参考文档：[http://www.cloudera.com/][http_www.cloudera.com]

官方共给出了多种安装方式：   
第一种方法必须要求所有机器都能连网，由于最近各种国外的网站被墙的厉害，我尝试了几次各种超时错误，巨耽误时间不说，一旦失败，重装非常痛苦。   
另一种离线安装，对系统侵入性最小,而且重装什么的都非常方便。后期的集群统一包升级也非常好。这也是我之所以选择离线安装的原因。

## **系统环境准备** ##

**1.网络配置(hadoop01,hadoop02 )**  
（1）修改主机名： vi /etc/hostname   
　　修改完hostname必须重启后才生效   
（2）添加hosts: vi /etc/hosts

#127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    #::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    
    127.0.0.1       localhost
    
    #set cdh
    192.168.0.45   hadoop01
    192.168.0.46   hadoop02

**2.SSH免密码登录(hadoop01,hadoop02)**  
只需要主节点和从节点之间SSH免密码登录就行，从节点和从节点之间不需要。   
先删除所有密钥 rm -rf ~/.ssh/\*

# ssh-keygen -t rsa
    # ssh-copy-id hadoop01
    # ssh-copy-id hadoop02

\# ssh localhost

注意这可能是ssh最快的方式了!!!

测试

hadoop01节点:
    
      ssh hadoop02
    
    hadoop02节点:
    
      ssh hadoop01

**3.关闭防火墙(hadoop01,hadoop02)**  
\#关闭防火墙

# systemctl stop firewalld
    # systemctl disable firewalld

**4.SELINUX关闭（hadoop01,hadoop02)**  
//关闭Selinux服务

# setenforce 0
    # sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
    # iptables --flush
    # reboot  #重启生效

**5.设置文件打开数量及最大进程数(hadoop01,hadoop02)**

# cp /etc/security/limits.conf /etc/security/limits.conf.bak
    # echo "* soft nproc 32000" >>/etc/security/limits.conf
    # echo "* hard nproc 32000" >>/etc/security/limits.conf
    # echo "* soft nofile 65535" >>/etc/security/limits.conf
    # echo "* hard nofile 65535" >>/etc/security/limits.conf

**6.同步时间(master,slave1,slave2)**  
安装ntp服务：

# yum -y install ntp

启动ntp服务，并设置开机自启：

# systemctl start ntpd
    # systemctl enable ntpd

**7.安装JDK配置环境变量（hadoop01,hadoop02)**  
先删除系统自带的java:

# rpm -qa | grep java
    
    tzdata-java-2016g-2.el7.noarch
    python-javapackages-3.4.1-11.el7.noarch
    javapackages-tools-3.4.1-11.el7.noarch
    java-1.8.0-openjdk-headless-1.8.0.102-4.b14.el7.x86_64
    java-1.8.0-openjdk-1.8.0.102-4.b14.el7.x86_64
    java-1.7.0-openjdk-1.7.0.111-2.6.7.8.el7.x86_64
    java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64

//删除上面显示的包：
    rpm -e --nodeps tzdata-java-2016g-2.el7.noarch
    rpm -e --nodeps python-javapackages-3.4.1-11.el7.noarch
    rpm -e --nodeps javapackages-tools-3.4.1-11.el7.noarch
    rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.102-4.b14.el7.x86_64
    rpm -e --nodeps java-1.8.0-openjdk-1.8.0.102-4.b14.el7.x86_64
    rpm -e --nodeps java-1.7.0-openjdk-1.7.0.111-2.6.7.8.el7.x86_64
    rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64

每个节点需要安装相同版本的Java。这里采用的是rpm方式安装Java.

// 默认解压到/usr/jave/jdk1.7.0_67-cloudera
    # rpm -i oracle-j2sdk1.7-1.7.0+update67-1.x86_64.rpm    
    # cd /usr/java
    # mv jdk1.7.0_67-cloudera default  #即JAVA_HOME=/usr/java/default

最好将JDK安装在/usr/java/default中，有的版本要求安装在此目录，要不然找不到JAVA\_HOME

由于是rpm包并不需要我们来配置环境变量，我们只需要配置一个全局的JAVA\_HOME变量即可，在/etc/profile末尾添加：

# set java env
    export JAVA_HOME=/usr/java/default
    export PATH=$PATH:$JAVA_HOME/bin

再source /etc/profile 立即生效

建议手动指定一下java的使用版本 alternatives --config java ，避免在安装Spark组件时报错

**8. 安装配置mysql**

yum install mysql-server -y
    
    设置开机启动：chkconfig mysqld on
    
    启动mysql：  service mysqld start
    
    查看状态：  service mysqld status
    
    进入: mysql 
    
    use mysql
    
    select host,user from user
    
    修改 mysql 权限： GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123' WITH GRANT OPTION;
    
    刷新权限：flush privileges;
    
    删除多余会对权限造成影响的数据：delete from user where host !='%';
    
    刷新权限: flush privileges;
    
    select host,user from user;
    
    quit 退出

创建数据库：

#为hive建库hive
    mysql>create database hive DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
    
    #为Activity Monitor建库amon
    mysql>create database amon DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
    
    #为Oozie建库oozie
    mysql>create database oozie DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
    
    #为Hue建库hue
    mysql>create database hue DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
    
    设置root授权访问以上所有的数据库,因为CM安装时会创建数据库，这里设置后安装CM时可以设置数据库的host为master:
    
    mysql>grant all privileges on *.* to 'root'@'master' identified by '123456' with grant option;
    mysql>flush privileges;

补充： 安装完成集群后，运行Sqoop程序出现如下错误：

Caused by: java.sql.SQLException: null,  message from server: "Host 'slave1' is not allowed to connect to this MariaDB server"  
  
是因为MariaDB不允许远程连接导致的,在MariaDB中运行：

mysql>grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
    mysql>flush privileges;

即可运行Sqoop程序了。

**9.安装第三方依赖包（hadoop01,hadoop02)**  
不安装这些依赖，安装Cloudera Manager时可能会报错

yum -y install chkconfig python bind-utils psmisc libxslt zlib sqlite cyrus-sasl-plain cyrus-sasl-gssapi fuse fuse-libs redhat-lsb
    
    yum  -y  install psmisc MySQL-python at bc bind-libs bind-utils cups-client cups-libs cyrus-sasl-gssapi cyrus-sasl-plain ed fuse fuse-libs httpd httpd-tools keyutils-libs-devel krb5-devel libcom_err-devel libselinux-devel libsepol-devel libverto-devel mailcap noarch mailx mod_ssl openssl-devel pcre-devel postgresql-libs python-psycopg2 redhat-lsb-core redhat-lsb-submod-security  x86_64 spax time zlib-devel

##       Cloudera Manager安装 ##

**1.安装Cloudera Manager Server 和Agent**  
主节点解压安装(hadoop01)

tar -zxvf cloudera-manager-centos7-cm5.11.1_x86_64.tar.gz -C /opt/

**2.配置 CM Server数据库（master）**  
将mysql-connector-java-5.1.44-bin.jar放到/opt/cm-5.12.0/share/cmf/lib下并初始化数据库:

# cp mysql-connector-java-5.1.44-bin.jar /opt/cm-5.12.0/share/cmf/lib
    /opt/cm-5.12.0/share/cmf/schema/scm_prepare_database.sh [-数据库类型] [-创建的数据库名] [-h主机名] [-u用户名] [-p密码]
    # cd /opt/cm-5.12.0/share/cmf/schema
    # ./scm_prepare_database.sh mysql temp -h hadoop01  -uroot -p123456 --scm-host hadoop01 scm scm scm

**3.配置 CM Agent(master)**  
修改/opt/cm-5.12.0/etc/cloudera-scm-agent/config.ini文件中的server\_host为主节点主机名

# vi /opt/cm-5.12.0/etc/cloudera-scm-agent/config.ini

[General]
    # Hostname of the CM server.
    server_host=hadoop01  //修改为主节点主机名

4.将Agent文件从主节点分发到其他从节点:(master)

# scp -r /opt/cm-5.12.0 hadoop02:/opt

**5.创建用户cloudera-scm(hadoop01 ,hadoop02)**  
每个节点上执行命令创建cloudera-scm用户，因为CM使用cloudera-scm用户管理。

# useradd --system --home=/opt/cm-5.12.0/run/cloudera-scm-server/ --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

**6.准备Parcels，用以安装CDH5**  
（1）在主节点hadoop01上，将cdh parcels安装包放置到/opt/cloudera/parcel-repo目录下，并修改权限：

cp CDH-5.12.0-1.cdh5.12.0.p0.29-el7.parcel /opt/cloudera/parcel-repo/
    cp CDH-5.12.0-1.cdh5.12.0.p0.29-el7.parcel.sha1 /opt/cloudera/parcel-repo/
    mv /opt/cloudera/parcel-repo/CDH-5.11.1-1.cdh5.11.1.p0.4-el7.parcel.sha1 /opt/cloudera/parcel-repo/CDH-5.11.1-1.cdh5.11.1.p0.4-el7.parcel.sha
    
    //这一步可以不用做
    chown -R cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo

（2）在所有cloudera-agent上创建parcels目录（这一步可以不用做）：

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

**7.启动 CM Server和Agent**  
（1）启动服务

//主节点启动(hadoop01)：
    # /opt/cm-5.12.0/etc/init.d/cloudera-scm-server start
    //所有节点启动(hadoop01,hadoop02)：
    # /opt/cm-5.12.0/etc/init.d/cloudera-scm-agent start

CM Server首次启动会自动创建表以及数据，不要立即关闭和重启，否则需要删除所有表和数据，重新安装

（2）添加开机自启动

# chmod +x /etc/rc.d/rc.local
    # vi /etc/rc.d/rc.local
    
    // 在此文件中添加启动命令即可实现开机启动
    //主节点启动(master)：
    # /opt/cm-5.12.0/etc/init.d/cloudera-scm-server start
    //所有节点启动(master,slave1,slave2)：
    # /opt/cm-5.12.0/etc/init.d/cloudera-scm-agent start

（3）启动错误

启动服务器时，使用tail -f /opt/cm-5.12.0/log/cloudera-scm-server/cloudera-scm-server.log 可以查看日信息，如果出现：
    
    2017-08-03 08:05:18,558 ERROR WebServerImpl:com.cloudera.server.web.cmf.search.components.SearchRepositoryManager: The server storage directory [/var/lib/cloudera-scm-server] doesn't exist.
    2017-08-03 08:05:18,558 ERROR WebServerImpl:com.cloudera.server.web.cmf.search.components.SearchRepositoryManager: No read permission to the server storage directory [/var/lib/cloudera-scm-server]
    2017-08-03 08:05:18,558 ERROR WebServerImpl:com.cloudera.server.web.cmf.search.components.SearchRepositoryManager: No write permission to the server storage directory [/var/lib/cloudera-scm-server]
    
    则：
    
    mkdir -p /var/lib/cloudera-scm-server
    chmod 777 /var/lib/cloudera-scm-server

(3)启动成功

首次启动成功，tail -f /opt/cm-5.12.0/log/cloudera-scm-server/cloudera-scm-server.log显示：
    
    2017-08-09 16:09:30,123 INFO ParcelUpdateService:com.turn.ttorrent.common.Torrent: Single-file torrent information:

非首次启动成功，显示：
    
    INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server

8.登录  
CM Server启动成功后，可以登录http://master:7180进行CDH部署。   
用户名：admin   
密码：admin

CDH部署  
1.选择节点

![cdh5SetupCM_E5_AE_89_E8_A3_8502.png][]  
  
  
![cdh5SetupCM_E5_AE_89_E8_A3_8503.png][]  
  
  
![cdh5SetupCM_E5_AE_89_E8_A3_8504.png][]

2.选择本地Parcel

![cdh5SetupCM_E5_AE_89_E8_A3_8505.png][]

![cdh5SetupCM_E5_AE_89_E8_A3_8506.png][]

### 3.服务器检查 ###

![cdh5SetupCM_E5_AE_89_E8_A3_8507.png][]

3.服务器检查

![cdh5SetupCM_E5_AE_89_E8_A3_8507.png][]  
出现如上图所示警告，则：

# sysctl -w vm.swappiness=10
    # echo "vm.swappiness=10" >>/etc/sysctl.conf
    
    //将下面两句添加到系统启动脚本中如`/etc/rc.local`，以便系统重启生效
    # echo never > /sys/kernel/mm/transparent_hugepage/defrag
    # echo never > /sys/kernel/mm/transparent_hugepage/enabled

4.选择服务

5.服务配置

![cdh5SetupCM_E5_AE_89_E8_A3_8509.png][]  
6.数据库设置

![cdh5SetupCM_E5_AE_89_E8_A3_8510.png][]  
  
  
![cdh5Setup_E6_95_B0_E6_8D_AE_E5_BA_93_E8_AE_BE_E7_BD_AE01.png][]   
  
  
![cdh5Setup_E6_95_B0_E6_8D_AE_E5_BA_93_E8_AE_BE_E7_BD_AE02.png][]

7.集群设置

![cdh5SetupCM_E5_AE_89_E8_A3_8511.png][]  
8.启动服务

![cdh5SetupCM_E5_AE_89_E8_A3_8512.png][]

遇到上述错误，如若安装hive组件且使用Mysql类型的数据仓库，那么需要为hive增加MySQL connector的驱动。

cp mysql-connector-java-5.1.42-bin.jar /opt/cloudera/parcels/CDH/lib/hive/lib/

![cdh5SetupCM_E5_AE_89_E8_A3_8513.png][]

oozie组件同样也需要数据库驱动：

# mv mysql-connector-java-5.1.41-bin.jar mysql-connector-java.jar
    # cp mysql-connector-java.jar /usr/share/java/

9.安装完成

![cdh5SetupCM_E5_AE_89_E8_A3_8515.png][]  
  
  
![cdh5SetupCM_E5_AE_89_E8_A3_8516.png][]

10.测试  
在主节点上执行以下模拟Pi的示例程序：

sudo -u hdfs hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 10 100

执行过程需要花一定的时间，通过YARN的后台也可以看到MapReduce的执行状态。

测试Spark2:

spark2-submit --class org.apache.spark.examples.SparkPi 
    --master yarn 
    --deploy-mode client /opt/cloudera/parcels/SPARK2/lib/spark2/examples/jars/spark-examples_2.11-2.2.0.cloudera1.jar 100

11.其它  
在Cloudrea Manager页面上，可以向集群中添加/删除主机，添加服务到集群等。

Cloudrea Manager页面开启了google-analytics，因为从国内访问很慢，可以关闭google-analytics

管理 -> 设置 -> 其他 -> 允许使用情况数据收集 不选

后记  
工欲善其事必先利其器，管理 Hadoop 集群，Cloudrea 是个不错的选择。
