cdh-5.10.0搭建安装

 

1.修改主机名为master, slave1, slave2

vim /etc/sysconfig/network

 

HOSTNAME = master

HOSTNAME = slave1

HOSTNAME = slave2

 

2.修改hosts文件(三个节点都要设置)

vim /etc/hosts

192.168.1.7 master

192.168.1.8 slave1

192.168.1.9 slave2

 

3.IP设置(三个节点都要设置)

DEVICE=eth0

HWADDR=4C:CC:6A:54:0B:D0

TYPE=Ethernet

UUID=0d5eac54-f26f-430e-8c7a-d2abea4df79e

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=static

IPADDR=192.168.1.7

GATEWAY=192.168.1.1

NETMASK=255.255.255.0

DNS1=114.114.114.114

DNS2=8.8.8.8

 

4.Selinux(三台机器都要设置)

  service iptables stop

   禁用

    sudo vim /etc/sysconfig/selinux

    内容:

     SELINUX=disabled

service iptables status

5.卸载与安装jdk(三台机器都要设置)

卸载:

  sudo rpm -qa|grep java

  sudo rpm -e --nodeps xxx yyy zzz

 安装:

  jdk-7u79-linux-x64.gz

  tar zxf jdk-7u79-linux-x64.gz

修改配置

  vim /etc/profile

   export JAVA_HOME=/usr/java/jdk1.7.0_79

   export JAVA_BIN=/usr/java/jdk1.7.0_79/bin

   export PATH=$PATH:$JAVA_HOME/bin

   export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

   export JAVA_HOME JAVA_BIN PATH CLASSPATH

初始化:

   source /etc/profile

6.ssh免密码登录(三台机器都要设置)

ssh-keygen

 

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

去掉三行注释

vim /etc/ssh/sshd_config

RSAAuthentication yes

PubkeyAuthentication yes

AuthorizedKeysFile  .ssh/authorized_keys

 

设置免密码

# cat ~/.ssh/id_rsa.pub | ssh master "cat - >> ~/.ssh/authorized_keys"

# cat ~/.ssh/id_rsa.pub | ssh slave1 "cat - >> ~/.ssh/authorized_keys"

# cat ~/.ssh/id_rsa.pub | ssh slave2 "cat - >> ~/.ssh/authorized_keys"

 

7.设置NTP服务

1)检查是否安装ntp服务器:rpm -q ntp

2)ntp安装

yum -y install ntp

service ntpd status

chkconfig ntpd on

安装完成后配置NTP服务为自启动:

chkconfig ntpd on

chkconfig ntpdate on

查看服务器自启动状态

chkconfig --list | grep ntp

  ntpd   0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

  ntpdate   0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

配置参数:

vim /etc/ntp.conf

 

restrict 192.168.1.7 mask 255.255.255.0 nomodify notrap

server 192.168.1.7 perfer

server  127.127.1.0     # local clock

fudge   127.127.1.0 stratum 10

 

注销:

 

#server 0.centos.pool.ntp.org iburst

#server 1.centos.pool.ntp.org iburst

#server 2.centos.pool.ntp.org iburst

#server 3.centos.pool.ntp.org iburst

 

重启ntp

service ntpd restart

检查ntp

ntpstat

 

同步cmserver时间

ntpdate -u 192.168.1.7

8.搭建MySQL数据库

  检查是否安装

  rpm -qa | grep -i mysql

  卸载

  yum -y remove mysql-libs*

  

  安装mysql

  cd /usr/sg/mysql

  

  rpm -ivh MySQL-server-5.6.29-1.el6.x86_64.rpm

  rpm -ivh MySQL-devel-5.6.29-1.el6.x86_64.rpm

  rpm -ivh MySQL-client-5.6.29-1.el6.x86_64.rpm

  

  修改配置文件位置

  cp /usr/share/mysql/my-default.cnf /etc/my.cnf

  

  初始化mysql及设置密码

  /usr/bin/mysql_install_db

  启动

  service mysql start

  

  cat /root/.mysql_secret  #查看root账号密码

  登陆

  mysql -uroot –pqKTaFZnl

  修改密码

  SET PASSWORD = PASSWORD('root1234');    

  重新登陆

  mysql -uroot -proot1234

  创建数据库:

> create database hive DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

> create database amon DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

> create database hue DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

> create database oozie DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

设置远程登陆

grant all privileges on *.* to 'root'@'%' identified by 'root1234' with grant option;

生效

flush privileges;

 

9.下载安装包:

  cm下载

https://archive.cloudera.com/cm5/cm/5/cloudera-manager-el6-cm5.10.0_x86_64.tar.gz

  cdh下载

  http://archive.cloudera.com/cdh5/parcels/5.10.0/CDH-5.10.0-1.cdh5.10.0.p0.41-el6.parcel

http://archive.cloudera.com/cdh5/parcels/5.10.0/CDH-5.10.0-1.cdh5.10.0.p0.41-el6.parcel.sha1

http://archive.cloudera.com/cdh5/parcels/5.10.0/manifest.json

10.安装cm

Master:

cp /usr/sg/cm/cloudera-manager-el6-cm5.10.0_x86_64.tar.gz /opt

tar zxf cloudera-manager-el6-cm5.10.0_x86_64.tar.gz

 

拷贝mysql的jdbc驱动包到/opt/cm-5.10.0/share/cmf/lib

 

所有节点创建Cloudera SCM User用户

useradd --system --home=/opt/cm-5.10.0/run/cloudera-scm-server/ --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

 

Master上初始化数据库

/opt/cm-5.10.0/share/cmf/schema/scm_prepare_database.sh mysql cm - -h192.168.1.7 -uroot -proot1234 --scm-host 192.168.1.7 scm scm scm

 

Master上修改Agent配置

vi /opt/cm-5.10.0/etc/cloudera-scm-agent/config.ini

修改server_host为master

 

 

同步Agent到其他节点

scp -r /opt/cm-5.10.0 root@slave1:/opt/ &

scp -r /opt/cm-5.10.0 root@slave2:/opt/ &

 

准备parcles(master)

mv CDH-5.10.0-1.cdh5.10.0.p0.41-el6.parcel /opt/cloudera/parcel-repo/

mv CDH-5.10.0-1.cdh5.10.0.p0.41-el6.parcel.sha1 /opt/cloudera/parcel-repo/

mv manifest.json /opt/cloudera/parcel-repo/

 

重命名sha文件(master)

mv CDH-5.10.0-1.cdh5.10.0.p0.41-el6.parcel.sha1 CDH-5.10.0-1.cdh5.10.0.p0.41-el6.parcel.sha

 

启动master上的server

/opt/cm-5.10.0/etc/init.d/cloudera-scm-server start

设为开机启动 vi /etc/rc.local(master)

/opt/cm-5.10.0/etc/init.d/cloudera-scm-server start

 

Master,slave1,slave2启动agent

/opt/cm-5.10.0/etc/init.d/cloudera-scm-agent start

设为开机启动 vi /etc/rc.local(每台机)

/opt/cm-5.10.0/etc/init.d/cloudera-scm-agent start

 

访问web页面http://192.168.1.7:7180

默认用户名/密码: admin/admin

 

 

 

 

11.常见问题

1)Cloudera 建议将 /proc/sys/vm/swappiness 设置为 10。当前设置为 60。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:

解决echo 10 > /proc/sys/vm/swappiness

2)

已启用“透明大页面”,它可能会导致重大的性能问题。版本为“CentOS release 6.7 (Final)”且发行版为“2.6.32-573.el6.x86_64”的 Kernel 已将 enabled 设置为“[always] madvise never”,并将 defrag 设置为“[always] madvise never”。请运行“echo never > /sys/kernel/mm/transparent_hugepage/defrag”以禁用此设置,然后将同一命令添加到一个 init 脚本中,如 /etc/rc.local,这样当系统重启时就会予以设置。或者,升级到 RHEL 6.5 或更新版本,它们不存在此错误。将会影响到以下主机:

解决:

方法2:设置/etc/rc.local文件

[root@getlnx06 ~]# vi /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

if test -f /sys/kernel/mm/redhat_transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
fi

使用上面的配置后必须重启操作系统才能生效,你也可以运行下面命令不用重启操作系统。

You must reboot your system for the setting to take effect, or run the following two echo lines to proceed with the install without rebooting:

[root@getlnx06~]#echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
[root@getlnx06~]#cat /sys/kernel/mm/redhat_transparent_hugepage/enabled
always madvise [never]
[root@getlnx06 ~]# 

 

Hive 缺失mysql驱动jar无法正常启动

 

Oozie缺失mysql驱动jar无法正常启动

mysql-connector-java-5.1.36-bin.jar 拷贝到/var/lib/oozie
