Cloudera Manager安装之利用parcels方式安装3或4节点集群（包含最新稳定版本或指定版本的安装）（添加服务）（CentOS6.5）（五）

参考博客

Cloudera Manager安装之利用parcels方式安装单节点集群

 Cloudera Manager安装之Cloudera Manager 5.3.X安装（三）（tar方式、rpm方式和yum方式）

　　ClouderManager官网的安装历史稳定版

https://www.cloudera.com/documentation/manager/5-1-x/Cloudera-Manager-Installation-Guide/cm5ig_install_older_cm5.html

说在前面的话（看清楚就好！！！）

　　 我这篇博客，是两种方式都使用过：（在/etc/yum.repos.d下的）

[hadoop@clouderamanager01 yum.repos.d]$ sudo vi cloudera-manager.repo
[hadoop@clouderamanager02 yum.repos.d]$ sudo vi cloudera-manager.repo
[hadoop@clouderamanager03 yum.repos.d]$ sudo vi cloudera-manager.repo

即（博主我推荐用这种！！！）（但是不需）

[cloudera-manager]
# Packages for Cloudera Manager, Version , on RedHat or CentOS  x86_64
name=Cloudera Manager
baseurl=https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5.3.6/
gpgkey =https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/RPM-GPG-KEY-cloudera
gpgcheck = 

或者（但是，需要自定义存储库）

[cloudera-manager]

　　我这里是，使用CM 5.3.x利用parcels方式集群安装CDH 5.3.x的3节点集群！（开始开工）

下载以下三个文件就好：

　　需要改CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel.sha1的名称和CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel.html的名称

　　同理，机器clouderamanager03也要去做。

关于/opt/cloudera/parcel-repo和/opt/cloudera/parcel（必须弄懂，别怕）

　　192.168.80.148   clouderamanager01　 （部署ClouderaManager-server和Mirror server）  （部署Agent） 　　　　（分配1G，我这里只是体验过程，当然你可以分配更多或更小)　

　　192.168.80.149   clouderamanager02    （部署Agent）　　　　　　　　　　　　　　　　　　　　　 （分配1G，我这里只是体验过程，当然你可以分配更多或更小)

　　192.168.80.150   clouderamanager03   （部署Agent）

　　部署ClouderaManager-server和Mirror server的机器，默认是存储在/opt/cloudera/parcel-repo。

　　部署Agent的机器，默认是存储在/opt/cloudera/parcel。

　　即，这也是为什么，我在下面这篇博客里写到。

Cloudera Manager安装之Cloudera Manager 5.3.X安装（三）（tar方式、rpm方式和yum方式）

　　博客里，提及到的tar方式来安装。

　　

　　

　　进入，CM安装的机器，自动生成的默认/opt/cloudera/parcel-repo目录下（在clouderamanager01主节点）

[hadoop@clouderamanager01 opt]$ pwd

　　将我们之前上传在/opt/softwares/cdh-5.3.6（其实这个用作为备份，万一以后丢失了再可以重新安装。免得再下载）的CDH离线安装包，

移动到这个/opt/cloudera/parcel-repo目录上去。

　　将

gpgcheck = 

　　改为

name=Cloudera Manager
baseurl=http://clouderamanager01/cm5/redhat/6/x86_64/cm/5.3.6/
gpgcheck = 

　　注意，此时，所有的机器（比如我这里是clouderamanager01、clouderamanager02和clouderamanager03）都要更改为

[cloudera-manager]
# Packages for Cloudera Manager, Version , on RedHat or CentOS  x86_64
name=Cloudera Manager
baseurl=http://clouderamanager01/cm5/redhat/6/x86_64/cm/5.3.6/
enabled =1
gpgcheck = 1

　　于是，将所有机器的/etc/yum.repos.d/clouder-manager.repo改好为本地的之后，再次刷新就好

clouderamanager[-]

　　

　　

　　有时候会是如下， 　　

　　这是，因为。我之前前面3台机器都没有启动服务，所以会是如下。三个自动会勾选。

　　以及重启下

[hadoop@clouderamanager01 parcel-repo]$ 

　　等上几分钟。

　　如果还是没有解决的话，说明那个文件cloudera-manager-agent-5.3.6-1.cm536.p0.244.el6.x86_64.rpm已经损坏了。重新下载它，再上传。

　　然后，再重启

sudo service cloudera-scm-server restart

　　就可以解决问题了。

　　如果还是没解决的话，那就换成在线的吧！（哎）

　　然后，接着下面

　　重复，执行上面的过程。这里省略，.....

直至如下界面.....

　　

　　如果你的网速慢的话，则会出现，

　　比如我还遇到过这样的一种情况，也就是说，clouderamanager01先安装成功，然后再次执行上面的重头开始，再来clouderamanager02和clouderamanager03安装成功！

安装Parcel到所有主机上（我这里是clouderaManager01、clouderaManager02和clouderaManager03这台机器上）
　　因为Parcel文件已经提前下载好了，第一个进度条会直接显示已下载，然后开始分配。这个过程实际上就是将Parcel内的软件解压缩安装到各个主机上的过程。耐心等待，时间会比较长，我安装3台主机（即在clouderaManager01、02和03上，安装3节点集群）大概是需要30分钟时间。（这里看个人的网速）

　　其实啊，这里分配就是解压。

 主机检查
　　检查就可以了，建议不要跳过。静静地等一分钟多点的时间

　　检查结果如下：

http://clouderamanager01:7180/cmf/express-wizard/wizard#step=hostInspectorStep

　　因为我这里，之前是在clouderaManager01、clouderaManager02、clouderaManager03和clouderaManager04安装过。

然后，后面，再clouderamanager01、clouderamanager02和clouderamanager03。

　　所以，会已经有了记录的痕迹。（当然，若是你第一次安装的话，就不会有这个问题出现的哈！）

　 Cloudera Manager安装之Cloudera Manager安装前准备(CentOS6.5）（一）

　　永久修改，我们直接修改配置文件，我们直接修改/etc/sysconfig/network

NETWORKING=yes
HOSTNAME=clouderaManager01

　　对应三台都要修改。我这里是自己，当时失误！主机名弄错大小写字母M了。

　　然后

sudo reboot

　　　这个问题怎么解决呢？

　　说白了swap就是交换区，当内存容不下这些数据时，就移动到磁盘那去。由于我们是大数据，不希望移动到磁盘。

[hadoop@clouderaManager01 ~]$ sudo free -m
             total       used       free     shared    buffers     cached
Mem:
-/+ buffers/cache:
Swap:
[hadoop@clouderaManager01 ~]$ sudo cat /proc/sys/vm/swappiness

[hadoop@clouderaManager01 ~]$ sudo sysctl -w vm.swappiness=
vm.swappiness =
[hadoop@clouderaManager01 ~]$ 

　　clouderaManager01和clouderaManager02和clouderaManager03都要执行。

　　

　　这个怎么来解决呢？是我们的Linux版本的bug问题。

touch /var/lock/subsys/local

echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag

　　clouderaManager01和clouderaManager02和clouderaManager03都要执行。

　　带你认识下安装成功之后的目录结构

安装完成之后，再安装所需的服务（其实，这一步，若你的内存和空间足够，最好选择所有服务）

　　其实啊，这步是选择集群中要安装的CDH服务，为了将来新增服务麻烦，我们这里选择所有服务。其中有暂时用不到的服务，我们可以在界面中停止服务，这样可以节省内存资源

　　这里，添加Cloudera Management Service服务

　　然后，关于安装其他的，如Zookeeper、Hive、HBase和Spakr、Hadoop等。这些。我就不赘述了。

　　因为，这是，我在自己的电脑虚拟机里搭建的。过卡和内存不够，以下不贴图和不写了。

　　

安装完毕后点继续

　　贴图，这里不写了。

　　

角色分配
　　分配各个节点的角色

数据库设置
　　CDH默认内嵌了一个数据库，如果你需要MySQL或者Oracle请选择使用自定义数据库，

　　  我这里，先点击测试连接，即选择CDH默认的内嵌数据库成功后点继续。

审核更改
　　 这里全部默认就可以了，直接继续。

安装完成，初始化
　　到这里集群已经安装部署完成了，CDH会自动对你选择的服务进行初始化设置，你也可以稍后自行开启。

初始化完成后，将进入主页面

常见错误

[hadoop@clouderaManager01 parcel-repo]$ sudo service cloudera-scm-server restart

./cloudera-scm-server: line 109: pstree: command not found
Starting cloudera-scm-server:                              [  OK  ]

　　主要因为没有安装pstree包。

解决办法：

[hadoop@clouderaManager01 parcel-repo]$ sudo yum install epel-release (安装yum 源)
[hadoop@clouderaManager01 parcel-repo]$ sudo yum provides pstree (找到提供pstree命令的包)
[hadoop@clouderaManager01 parcel-repo]$ sudo yum install psmisc (安装对应的包)

然后，
[hadoop@clouderaManager01 parcel-repo]$ sudo service cloudera-scm-server restart

解决办法：

　　在失败的主机上，终端执行

sudo mv /usr/bin/host /usr/bin/host.bak

　　然后重试。

　　安装过程一直卡在"正在获取安装锁"状态界面

　　解决办法：
在卡住的主机上，删除/tmp文件夹中的所有scm_prepare_node.开头的文件，清空yum缓存，然后重启主机。

sudo cd /tmp
sudo rm -rf  scm_prepare_node.*
sudo yum clean all
sudo reboot

安装完毕后NameNode格式化失败，报以下错误

IncorrectVersionException: Unexpected version of storage directory /data/dfs

　　解决办法：

　　删除NameNode节点的/data/dfs文件夹，重新添加主机。

如何更改节点ip

　　解决办法：
　　重新设置每台主机的hosts文件，完成后进入主机界面，点击重新运行升级向导，再走一遍之前的流程即可。

[bigdata@cmbigdata2 ~]$ ntpdate pool.ntp.org
[bigdata@cmbigdata3 ~]$ ntpdate pool.ntp.org
[bigdata@cmbigdata4 ~]$ ntpdate pool.ntp.org

　　对于，第二个黄色警告的解决办法！

    Cloudera 建议将 /proc/sys/vm/swappiness 设置为 。当前设置为 6。使用 sysctl 命令在运行时更改该设置并编辑 /etc/sysctl.conf 以在重启后保存该设置。您可以继续进行安装，但可能会遇到问题，Cloudera Manager 报告您的主机由于交换运行状况不佳。以下主机受到影响：
cmbigdata[-]

　　

[bigdata@cmbigdata1 ~]$ su root
Password:
[root@cmbigdata1 bigdata]# echo  > /proc/sys/vm/swappiness

　　最后，我的初步安装是

　　因为，在以后，自己是可以修改的。

所以，CDH默认内嵌了一个数据库，无法通过。我这里选择需要MySQL或者Oracle请选择使用自定义数据库，

　　比如Hive， oozie 元数据库配置，使用我们安装的mysql来存放元数据，其中数据库名，用户名和密码需要预先创建好的。这里。请移步

　如果你是一名有经验大数据工程师，无论是安装jdk（注意：CentOS6.5有自带的jdk），还是安装mysql。都是先查看系统是否已经安装Mysql包。
